Under Sink Water Filter Systems - A Guide to Finding the Best One
0 comments Posted by ariya at 22:41When it comes to quality, filtering devices that use multiple filter technologies are always more effective at removing contaminants. This is because it's impossible to remove all the different types of contaminants with one type of filter. For example, sediment filters will remove particulate that give water a bad taste and odor, sediment, and maybe chlorine, but a carbon filter is needed to remove synthetic chemicals, chlorinated byproducts, and pharmaceutical drugs.
The best under sink water filter systems will also refrain from removing all the beneficial trace minerals that are naturally found in water. Minerals like potassium, iron, calcium, magnesium, and sodium are all an important part of our health, and water is a major source of them.
Then to really assure that under sink water filter systems are reliable, look for proof that the claims made about it are true. Some manufacturers will have their systems certified by highly-regarded agencies in order to show that the claims made about it are true.
Now here's one of the biggest secrets to finding under sink water filter systems that are affordable: buy them factory-direct through the manufacturer. This can often be done on the Internet. By doing this, you won't have to pay the ridiculous markups that retailers always tack on to make themselves a nice profit. In my opinion, this is the ultimate gift from manufacturers!
And understand that you don't' have to pay hundreds of dollars for quality under sink water filter systems. Most manufacturers feel that consumers will pay a higher price, or premium, to use a filtration system that has their name on it. But trust me, you can get a system that's just as good for a lot less!
You can learn about the under sink water filter systems that I recommend, which I use in my home and only cost $100 by visiting my website listed below. As far as quality goes, you won't find anything better at a lower price. You know why I know? Because I've compared them all!

Renovating Your Kitchen? - Water Filters and Reverse Osmosis Systems
0 comments Posted by ariya at 23:53Water filtration systems have become a standard fixture in most kitchens today, especially as more and more scientists and health professionals report that most if not all of our drinking water supplies are contaminated with human-made pollutants, including not just municipal systems, but wells, lakes, rives, and glaciers. Unfortunately, bottled water has been shown to have its own host of problems, including serious health and environmental effects. However, while a good water filtration system is the best way to ensure healthy and safe drinking water, it's not enough to install just any filter in your home. Though the purpose of any water filtration system is to improve the quality and taste of drinking water, there is a wide range of filters available, each with varying costs and effectiveness. The process of planning a kitchen renovation is a perfect time to consider the different water filter options. Some of the most popular filters are explained below to help you choose the best water filter for your home.
Reverse Osmosis
Reverse osmosis is one of the most effective filtration methods available today. Even though the process has been known for over 100 years, it wasn't until the 1950s that the U.S. government developed it as a way for the Marines to desalinate water to make it drinkable. By way of brief explanation, "regular" osmosis occurs when molecules pass through a permeable membrane to equalize the concentration of molecules on both sides. As its name implies, reverse osmosis is when the opposite occurs. Instead of equalizing the concentration of substances on both sides of the membrane, water pressure pushes pure water on one side of a membrane, leaving a concentration of pollutants on the other.
Reverse osmosis typically also employs two carbon filters and/or other pre-filters, which work to remove a wide range of dangerous contaminants, including lead, mercury, and arsenic. Reverse osmosis is also effective at removing virtually all pharmaceutical drugs, coliform bacteria, E. coli, percolate, VOCs, viruses, fluoride, chlorine, chloramines, herbicides, pesticides, cryptosporidium, THMs, and MTBEs. In fact, while typical faucet or counter top filters are 1 stage filters, meaning they have only 1 basic carbon filter, reverse osmosis systems typically offer a 5 stage filtration system. Furthermore, while countertop filters have a 1-5 micron rating, which means contaminates smaller than 1 micron (such as asbestos, insecticides, may not be filter out), a reverse osmosis filter typically holds a micron rating of.0001. While reverse osmosis systems can cost more upfront, their filters only need to be replaced once a year, whereas counter top filters need replacing every couple of months.
Although reverse osmosis effectively removes an impressive array of unhealthy contaminants, it can also remove important minerals that contribute to taste and health of water, including magnesium, calcium, and potassium. Some researchers suggest these important minerals are also found in common foods and are therefore not needed in drinking water. Other health professionals, however, report that long-term intake of de-mineralized water can be unhealthy and can lead to mineral deficiency and/or an unhealthy level of acidity in the body. Additionally, reverse osmosis generally requires between two to three gallons of water to produce one gallon of purified water, which some experts consider wasteful.
Other Popular Water Filters
Other popular filters include water filter pitchers, which are very easy to use and have a low initial cost. Water pitcher filters typically can reduce lead, copper, chlorine, and chlorine by-products. However, while any filter is better than no filter, pitcher filters are probably the least effective filters for their cost, especially considering that filters will need to be replaced every few months. Some pitcher filters may also be slow and prone to clog. Because pitcher filters have such a short life, they may not be practical for a family of four or more who might consume a couple of gallons of water a day.
Filter faucets or filters installed directly on the faucets are also popular because, like pitcher filters, they are very easy to use. Filter faucets are usually easily placed onto the head of a faucet, and they conveniently allow a person to switch from filtered to unfiltered water. Most filter faucets effectively remove lead, pesticides, sediments, and chlorine. However, because they typically use a similar type of filter as a water pitcher, the filter needs replacing often and filtering can be slow.
Another popular type of filter are counter-top water filters, which hook directly to the faucet after the aerator is removed. Counter-top filters provide a level of filtration higher than a water pitcher or filter faucet because it uses a combination of carbon filters and other filters. Counter-top filters are also less likely to clog than a pitcher filter or a filter faucet. They also allow a large amount of water to be filtered without having to alter any plumbing.
Similar to counter-top water filter, under sink filters can filter large amounts of water. However, unlike counter top filters, they don't take up valuable counter space and instead attach to pipes under the sink. They are also typically more effective than pitcher types of water filters because under sink filters offer a two-step filtering process. However, under sink filters require modification to the plumbing (sometimes by a professional) and drilling a hole through the sink or countertop for the dispenser, which may mean longer installation time than other filters. They also take up room under the sink.
Kitchen renovation can be an exciting and creative time. As you consider which type of water filtration system would work best in your kitchen keep in the mind the following tips. First, you may want to either have your water tested or you may want to refer to your local annual quality report to ensure your water filter is removing contaminants specific to your drinking water supply. Second, your water filter should be certified by the National Sanitation Foundation (NSF), and, third, to ensure the life and quality of your filter, your filter needs to be maintained according to manufacture recommendations.

Water filtration or treatment in itself is a quite a large topic with many methods and technologies involved. Most household water filters/treatment systems are designed to remove various contaminants such as chlorine, lead, mercury, Volatile Organic Chemicals (VOCs), Total Dissolved Solids (TDSs), Cryptosporidium, Chloramines, pesticides, herbicides, Giardia and other bad smell or taste elements.
Feature and Function Differences
Most water filters work on the same general process. Water is passed through a filtration agent (physical, chemical or ultra-violet) where contaminants are either removed or neutralized. The treated water is then either dispensed out of the system or is stored in a storage tank for future use. Generally, most water filters are fairly simple and inexpensive items that aren't very different from one manufacturer to the next. Below is a list of features and functions which you should consider before buying a water filtration system.
1). Filtering Technology
The first and most common sort of filter uses a physical barrier to remove suspended particles such as mud, silt, sand or rust as well as micro-organisms such as Giardia or Cryptosporidium. Physical filters are measured by microns. The finer the filter the smaller the micron number and the more types of particles can be removed from the raw water.
Another type of filter uses chemical processes to remove or neutralize potentially harmful contaminants in raw water. Depending on the type of contaminant, the filter elements can comprise of activated charcoal, copper, zinc etc.
The newest form of filtration technology is to use ultra-violet light to destroy bacteria, viruses or pathogens in water. The ultra-violet light is typically encased in a tank where-by the water is treated either when in storage or is run through a ultra-violet canister. The ultra-violet light deactivated the DNA of the organic particulates which ruin their ability to reproduce and cause disease.
Typically, a water filtration system will contain more than one type of filter because each filter has its own specific strengths and together enable a much wider spectrum of filtration.
2). System Types
There are a few basic types of water filters that range from small portable units to units that can supply an entire house or office. Here are the more common types:
Counter-top: These types of filters are placed on top as of the counter as suggested by the name and is connected to the faucet. The system normally has limited capacity while the filtered water is only available at the faucet.
Under-counter: These systems are very similar to the counter-top systems in that they have smaller capacities and only provide treated water to one faucet. The difference is that these systems don't take up valuable counter space however would require more sophisticated plumbing which makes it slightly more expensive.
Faucet Mounted: These systems are the cheapest and easies to install however offer the least amount of filtration. The system is mounted on the faucet itself and offers treated water to that faucet alone.
Whole House: These water filter systems are typically the most comprehensive and costly filter types that will be needed for a house or office. These systems attach to the pipe mains before entering the house/office which means that they will supply treated water to the entire house/office. These water filters are generally quite expensive to buy and maintain however all water in the house is treated.
Water Softeners: These types of water filters are used specifically to remove only some types of contaminants, namely unwanted elements such as calcium, magnesium, lime, and iron from a household's water supply. These elements make water taste metallic and salty.
Dispensers/Pitcher Water Filter: These systems are normally very simple filter assemblies that are built into a Pitcher/Dispenser. Again, this type of filter is very simple and cheap however doesn't filter contaminants all that well compared to the more comprehensive examples.
Portable: These water filters are made to be portable, some are designed for camping and light travel while some are built into sports drink bottles. Interestingly, an ultra-violet light pen is available which should act as a microbe de-activator similar to more complex household systems as mentioned earlier.
3). Capacity
There are generally two measurements for water filters that use "capacity". Capacity can be used as a measure to determine how much water the filter can actually treat before it needs filter replacements.
On the other hand, capacity is also a measure of the storage tank if the water treatment system is built with a storage tank. This goes hand-in-hand with the flow rate. This measurement is normally in gallons per minute. It should be noted that for counter-top or under-sink applications, flow rate isn't that important as waiting a few seconds longer to fill a glass of water won't be much of an issue. However, flow-rate is very important for Whole House systems, you won't want to be stuck in the shower with no water.
It should be noted that capacity and flow rates are directly related to how expensive the system will be.
4). Costs
When choosing to buy a water filter, you must also consider the maintenance and running costs of the filter. Generally the more complex and higher capacity systems will cost more to maintain and also more to run. Depending on the amount of water treated, water filter systems will need their filters replaced or treated every so often.
Additionally, some complex filters like Reverse Osmosis water filters will only produce 1 gallon of water for every 4 gallons of water supplied which will mean an increase in your water bills too. Further to this, ultra-violet light systems will also require a power source which will also affect your electricity bills.
In conclusion, I hope I have shed some light on buying water filters. The list of points in this article are by no means exhaustive but should serve as a rough guide in the selection process.

Get Better Tasting Water in Your RV by Installing a Drinking Water Filter
0 comments Posted by ariya at 23:15The drinking water filter mod is one of those things that should come straight from the factory for all RVs. The way RV holding tanks and plumbing systems are designed and utilized tends to promote bacterial growth if not sanitized on a regular basis. And more importantly, it's not all that uncommon to get a bad batch of water from a seemingly safe water source. In addition to sanitizing your RVs plumbing system frequently, filtering the water before it get's in to your system goes a long way in preventing bad water taste and potentially harmful parasites and bacteria from having their way with your system. The last thing you need when camping is to be enjoying your toilet more than the outdoors.
Using Your Water for Drinking and Cooking
Although there are several approaches to providing clean water for your RVing needs, this mod focuses on drinking and cooking water filtration. Of course, filtering your entire RV water supply system is an option but it is not always necessary. Most water sources are chlorinated and have enough protection to minimize bacterial growth. It just might not taste very good. Again, sanitizing often and not letting your water pipes, water heater, and fresh water tank sit without use will stave off 99% of bacterial growth. Assuming you have decent water to start with, the drinking water filter will provide great taste and protection in a simple to use manner.
Drinking Water Filter Types - Portable and Under-Counter Mount
The simplest approach to modding your RV with a drinking water filter is the countertop style filter. This system uses a standard, replaceable 10-inch filter cartridge and houses it in a plastic canister that sits on your counter. The water is fed to the unit through a tube hooked up to your sink faucet, and includes a spigot to serve the filtered water. This has the advantage of being portable. You can take the filter system with you for use in another RV, or even your home for that matter. If you are looking for a quick and easy way to get great tasting water, then your mod work here is done.
The most arguably popular drinking water filter mod though is the permanent-mount under-sink type, where the filter cartridge is mounted under the sink and the dispenser is mounted to the countertop or sink. The water supply to the dispenser is connected via a tee fitting placed in the cold water supply pipe used by the sink faucet. This makes using the dispenser easier and requires less counter space. And the filter housing is placed in an out of the way location under the sink, in a cabinet, or other convenient spot.
Tools Needed for Permanent Installation
Doing this mod is pretty straightforward, but requires a few tools you might not have handy in your mod tool set. These are a PEX or plastic tubing cutter, and a hole saw. Using a tubing cutter will help ensure there are no burrs on the tubing after cutting, which reduces the chance of a leak at the fittings where the tubing slides in. The hole saw is necessary since the dispenser is secured by a threaded shaft on the bottom of the dispenser, which must go through the sink or countertop, and is secured underneath the sink or countertop using a large washer and nut. Some dispensers only require a 1/2" hole for the threaded shaft so you might not need a hole saw. A 1/2"drill bit will work. Others may need a larger mounting hole so a hole saw is a must.
Beginning the Installation
Once you have the right tools for the job, installation is easy. Start by locating where you want to mount the dispenser. If you plan to mount the dispenser through the countertop, place some masking tape over the area you will be drilling through to help prevent splintering. If you plan to mount the dispenser through a metal sink shoulder, drill slowly if using a hole saw to prevent overheating the bit. After drilling the dispenser mounting hole, place the dispenser mounting shaft through the hole and secure with the supplied hardware.
Finding a Water Source to Tap In To
The next step is to locate a suitable place for the tee fitting in the cold water line going to the sink faucet. The tee fitting taps in to the line and provides the water supply connection for the dispenser. You can tap in to any cold water line but under the sink is the most convenient. Here is where you use your handy dandy PEX tubing cutter. Before cutting, be sure your water pump it switched off and all pressure in the line is relieved. Otherwise you're in for a real mess. Now carefully cut a 1" section out of the cold water line, which will require two cuts. If you have enough room to move the lines away from each other 1", then you may not have to do the second cut.
Installing the Tee Fitting
Water filter kits usually come with all the fittings necessary for a typical installation. This mod uses a plastic tee fitting which slips in between the cut tubing and a brass shutoff valve that serves both to provide the water supply to the dispenser and to turn off the supply if you need to change the filter or winterize. Thread the brass fitting in to the tee fitting using plumbers tape around the threads to prevent leakage.
Fitting the Brass Water Supply Shutoff Valve
Next, the water supply tubing needs to be attached to the brass shutoff valve. Don't worry about the length of the tubing at this point. The idea here is to secure the tubing to the fitting first since doing this requires a couple of end wrenches to secure. You might not have much room to use the wrenches in a tight compartment. The brass fitting is a compression type fitting so you need to slide the compression nut on first, then the small compression ferrel. Insert the tubing in to the fitting and tighten the compression nut fairly tight but not too tight.
Now secure the plastic tee fitting to the cold water line by sliding the round plastic threaded nuts on to each side of the cut tubing, then insert the tee fitting. Secure the nuts to the fitting taking care to not over tighten. You can use pliers to do this but make sure you hold the fitting body securely so you don't damage the water line.
Mounting the Water Filter Cartridge
The next step is to mount the water filter. Find a suitable location near the the tee fitting you just installed. The mod shown in the pictures uses a simple plastic bracket that the filter snaps in to. Secure the bracket and snap the filter in to place. Now you can measure how much tubing you need to go from the dispenser to the filter, and from the filter to the shutoff valve. Measure the distance for each and then add 6". This extra tubing will help with any bends required when routing the tubing. Cut the tubing with the tubing cutter to the appropriate length.
Attaching the tubing is incredibly simple with the type of filter and dispenser used in this mod. All you have to do is insert the tubing in to the ends of the filter and in to the bottom of the dispenser. No compression fittings or special tools are required. The tubing may appear to be loose in the filter and dispenser but try pulling the tubing out. You can't. The fittings hold the tubing in place and water pressure actually prevents the connections from leaking. Just be sure to connect the lines correctly, observing the filter input and output arrows.
Do a Final Leak Check
All that is left is to do now is turn on the water pump and check for leaks. Tighten fittings if necessary but don't overtighten. Let the dispenser run for a minute or two to eliminate charcoal sediment in the new filter. Now enjoy a great tasting glass of water!
Tips
1. Whatever brand filter you choose to buy, be sure it has been certified by the National Sanitation Foundation, or NSF. The NSF tests water filters to make sure that the manufacturer labels are telling the truth about performance. Avoid "generic" filters that have little or no information on the filter housing or packaging. Also avoid buying solely on price. Cheaper doesn't always mean good. Remember the Yugo?
2. Although the drinking water filter in this mod is suitable for drinking and cooking needs, it does nothing for the rest of the water in the system. If you are not one to sanitize your plumbing system often, you should probably use a whole house filter to minimize bacterial growth and ensure safe water for other uses. See the resources below for filters designed for applications like this.

The tap water that comes out of your faucet is perfect. Get a filter or be a filter. Which of these two sentences are more true? Both are partially true.
In many places, tap water does not taste good. In other places, tap water has tiny amounts of substances you would not want to drink - and over a lifetime might have an affect on you.
There are many kinds of potential problems in tap water. Even if your city provides good water, it has to travel a long way through old pipes on the way to your house.
I use a whole-house ten micron sediment filter to filter all water going into my house. I change the filters every five months, and they are filthy and red-colored, because of the rust and dirt in the water. When you use a whole-house filter, shower heads and faucet screens don't clog. Whole-house filters are separate from drinking water filters.
All reverse osmosis water systems require both sediment and carbon pre-filters. All filters need to be changed. Plan on changing sediment and carbon filters every six months or sooner, and reverse osmosis membranes every 2-3 years.
It's best to buy a dissolved solids meter, and test your water every month to make sure the system is working right. Pure water will measure zero parts per million of dissolved solids. Tap water will usually measure at least 200 parts per million.
Don't get a liquid chemical test set, get a $25-$50 portable battery-operated tester with a LCD readout. These cheap meters only show the total dissolved solids in water - they do not tell you what is in the water.
Water filter systems and replacement filters are available on Ebay and Amazon, and many other places - even retail stores.
The hardest parts of installing water filters are connecting to the supply side of the water into your house, connecting to a drain line for the waste water, and installing a clean water faucet onto your sink. The rest of a water filter installation is easy.
You may need a plumber, or to buy a system where they will install it for you. The best systems have clear plastic casings, so you can see how dirty the filters get. The best systems also use standard-sized replacement filters, so you don't have to buy tiny, expensive, and proprietary filters.
Reverse osmosis water filters require both a sediment and a carbon filter in front of them, to screen out the dirt and most of the junk, before the water enters the reverse osmosis filter.
A sediment filter blocks particles larger than five or ten microns. That's an improvement over tap water, but it does not help the taste, or filter out tiny or dissolved nasty stuff in the water. The next step is a carbon block filter.
Almost all carbon block filters are activated. Activation is a process where high pressure steam is passed through coal to purify it so that it becomes almost pure carbon. Carbon is the fourth most common element in the universe, and is needed for life. Carbon makes an excellent filter, especially when extruded into a solid block.
Activated carbon block filters strain water to trap much more particles than a sediment filter can. Activated carbon filters have a positive charge to attract chemicals and impurities. As the water passes through the positively-charged carbon, the negatively-charged contaminants are attracted and bound to the carbon.
Activated carbon block filters strain out sediment, dirt, bacteria, algae, chlorine, some pesticides, asbestos, and much more. They filter sub-micron size particles, making quality water that tastes good.
The water passing through activated carbon blocks still has some particles, chlorine, nitrates, fluoride, and other dissolved junk. The next step for the best quality water is a reverse osmosis filter.
Reverse osmosis filters force water through 0.0001 micron-wide holes, through semi-permeable membranes. Long sheets of membranes are sandwiched together and rolled up around a hollow central tube in a spiral.
The reverse osmosis filter removes 99% of the remaining junk in the water. It takes almost everything out, even the calcium and magnesium in the water. Most often a small carbon filter is used after the reverse osmosis filter, to improve the taste and catch a bit more of that 1% of junk the reverse osmosis filter lets go though.
Even after sediment, carbon block, and reverse osmosis filters, water is still not perfect. Chloramines and metal ions, while reduced, may still be in the water. For this reason, some systems include a final deionizing (DI) filter.
DI filters are usually cartridges filled with plastic-like resin crystals that grab the remaining ions in the water. After the DI filter, the water is very pure.
Reverse osmosis water filter generate waste water, and they produce only a few drops of clean water per minute. For this reason, most reverse osmosis systems have a storage tank to accumulate water. All reverse osmosis systems have a drain line for waste water, that is "wasted". The waste water can be used for plants, dumped down the drain, etc.
Ultra-pure water can grow algae very easily. When you take chlorine and other nasty stuff out of water, tiny microbes and sunlight can combine to make a perfect environment to grow harmless algae.
The quality of water filtered this way is cleaner than even distilled water. Some people think pure water tastes flat. Some people add a tiny amount of sea salt to pure water. For me, no salt is needed, pure water tastes like water should.
The Internet has baseless scare stories about how ultra pure water is dangerous. Hogwash. If you inject pure water, it may hurt you. Drinking pure water does not hurt anyone unless they are fasting.
The instant that pure water hits your mouth it's no longer pure. Nothing is better for making coffee, cooking, and ice cubes, than using pure water.
My observations over 20 years show that pets, plants, and people really like it. When growing sprouts - with pure water, I found they grew twice as fast as with tap water.
The truth is that ultra-pure water is missing minerals. If you get calcium and magnesium in your diet, you are more than ok. Ultra pure water has no lead, copper, barium, or other garbage.
For me the trade-off is clear. What I want from water is water. As long as you get calcium and other minerals from food or supplements you should be fine. Also, too much copper is not good for you, so why get it in your water?

If you are looking for a quick and easy way to get great tasting water, then your mod work here is done.
The most arguably popular drinking water filter mod though is the permanent-mount under-sink type, where the filter cartridge is mounted under the sink and the dispenser is mounted to the countertop or sink. The water supply to the dispenser is connected via a tee fitting placed in the cold water supply pipe used by the sink faucet. This makes using the dispenser easier and requires less counter space. And the filter housing is placed in an out of the way location under the sink, in a cabinet, or other convenient spot.
Tools Needed for Permanent Installation
Doing this mod is pretty straightforward, but requires a few tools you might not have handy in your mod tool set. These are a PEX or plastic tubing cutter, and a hole saw. Using a tubing cutter will help ensure there are no burrs on the tubing after cutting, which reduces the chance of a leak at the fittings where the tubing slides in. The hole saw is necessary since the dispenser is secured by a threaded shaft on the bottom of the dispenser, which must go through the sink or countertop, and is secured underneath the sink or countertop using a large washer and nut. Some dispensers only require a 1/2" hole for the threaded shaft so you might not need a hole saw. A 1/2"drill bit will work. Others may need a larger mounting hole so a hole saw is a must.
Beginning the Installation
Once you have the right tools for the job, installation is easy. Start by locating where you want to mount the dispenser. If you plan to mount the dispenser through the countertop, place some masking tape over the area you will be drilling through to help prevent splintering. If you plan to mount the dispenser through a metal sink shoulder, drill slowly if using a hole saw to prevent overheating the bit. After drilling the dispenser mounting hole, place the dispenser mounting shaft through the hole and secure with the supplied hardware.
Finding a Water Source to Tap In To
The next step is to locate a suitable place for the tee fitting in the cold water line going to the sink faucet. The tee fitting taps in to the line and provides the water supply connection for the dispenser. You can tap in to any cold water line but under the sink is the most convenient. Here is where you use your handy dandy PEX tubing cutter. Before cutting, be sure your water pump it switched off and all pressure in the line is relieved. Otherwise you're in for a real mess. Now carefully cut a 1" section out of the cold water line, which will require two cuts. If you have enough room to move the lines away from each other 1", then you may not have to do the second cut.
Installing the Tee Fitting
Water filter kits usually come with all the fittings necessary for a typical installation. This mod uses a plastic tee fitting which slips in between the cut tubing and a brass shutoff valve that serves both to provide the water supply to the dispenser and to turn off the supply if you need to change the filter or winterize. Thread the brass fitting in to the tee fitting using plumbers tape around the threads to prevent leakage.
Fitting the Brass Water Supply Shutoff Valve
Next, the water supply tubing needs to be attached to the brass shutoff valve. Don't worry about the length of the tubing at this point. The idea here is to secure the tubing to the fitting first since doing this requires a couple of end wrenches to secure. You might not have much room to use the wrenches in a tight compartment. The brass fitting is a compression type fitting so you need to slide the compression nut on first, then the small compression ferrel. Insert the tubing in to the fitting and tighten the compression nut fairly tight but not too tight.
Now secure the plastic tee fitting to the cold water line by sliding the round plastic threaded nuts on to each side of the cut tubing, then insert the tee fitting. Secure the nuts to the fitting taking care to not over tighten. You can use pliers to do this but make sure you hold the fitting body securely so you don't damage the water line.
Mounting the Water Filter Cartridge
The next step is to mount the water filter. Find a suitable location near the the tee fitting you just installed. The mod shown in the pictures uses a simple plastic bracket that the filter snaps in to. Secure the bracket and snap the filter in to place. Now you can measure how much tubing you need to go from the dispenser to the filter, and from the filter to the shutoff valve. Measure the distance for each and then add 6". This extra tubing will help with any bends required when routing the tubing. Cut the tubing with the tubing cutter to the appropriate length.
Attaching the tubing is incredibly simple with the type of filter and dispenser used in this mod. All you have to do is insert the tubing in to the ends of the filter and in to the bottom of the dispenser. No compression fittings or special tools are required. The tubing may appear to be loose in the filter and dispenser but try pulling the tubing out. You can't. The fittings hold the tubing in place and water pressure actually prevents the connections from leaking. Just be sure to connect the lines correctly, observing the filter input and output arrows.
Do a Final Leak Check
All that is left is to do now is turn on the water pump and check for leaks. Tighten fittings if necessary but don't overtighten. Let the dispenser run for a minute or two to eliminate charcoal sediment in the new filter. Now enjoy a great tasting glass of water!
Tips
1. Whatever brand filter you choose to buy, be sure it has been certified by the National Sanitation Foundation, or NSF. The NSF tests water filters to make sure that the manufacturer labels are telling the truth about performance. Avoid "generic" filters that have little or no information on the filter housing or packaging. Also avoid buying solely on price. Cheaper doesn't always mean good. Remember the Yugo?
2. Although the drinking water filter in this mod is suitable for drinking and cooking needs, it does nothing for the rest of the water in the system. If you are not one to sanitize your plumbing system often, you should probably use a whole house filter to minimize bacterial growth and ensure safe water for other uses. See the resources below for filters designed for applications like this.

Under sink water filters are an extremely handy thing to have. They allow you the convenience of having clean, safe drinking water coming out of a separate faucet on your kitchen sink that can also be used for cooking. It will require either a plumber or someone with professional experience to install an under sink water filter. Once it is done though, there is very little maintenance. There are several different kinds of under sink water filters. The one you need will depend on how contaminated your water is.
Reverse Osmosis Drinking Water Systems
This is typically the most powerful type of under sink water filters. It is excellent for removing lead, arsenic, copper, chlorine, cadmium, giardia, pesticides, salt, trihalomethanes, sulfates, cysts, nitrates, as well as some bacteria and viruses. However there some disadvantages to a reverse osmosis filtering system. For one, it tends to waste a lot of water in the filtering process. Second, it will filter out the good minerals that your body needs as well as the bad. Before choosing this type of system, get your water tested. Use a reverse osmosis system only if your water is full of contaminants and bacteria. Then get yourself some trace minerals from the health food store to replace the healthy minerals you would be missing. If you decide to go for a simpler system than a complete reverse osmosis unit, the two best under sink water filters on the market right now are:
Aquasana - Aquasana water filters were voted ‘best buy’ by Consumer Magazine 5 years in a row. That shows great quality. They have a basic under sink water filter as well as a deluxe model. Their water filters are priced great and have a good manufacturer’s warranty which is very important.
Crystal Quest - Crystal Quest has been around a long time and has over 30 years of industry expertise. Their water filters are known for being of excellent quality and produce some of the healthiest and great-tasting water around. They also come with an excellent manufacturer’s warranty.
These two under sink water filters use a combination of filter technologies which is why they are so great. They use one or more of these technologies:
- ATS Ion Exchange - removes heavy metals like lead
- Carbon Block - removes chemicals that cause bad taste and odor
- Doultion Ceramic - removes biological contaminants
- KDF-55 - removes heavy metals and kills bacteria
- UltraFiltration - removes extremely small contaminants
Our tap water has been shown to have traces of prescription drugs, including antibiotics, anti-convulsants, mood stabilizers and sex hormones. That is scary stuff. Finding a great under sink water filter can help to ensure that you are drinking and cooking with clean and safe water.

How To Choose The Right Home Water Filters And Water Purifiers For Your Needs
0 comments Posted by ariya at 22:15When it comes to home water filters and water purifiers, consumers have many choices. You can choose from leading name brands such as Brita, Culligan, PUR, and Braun. You can go with counter top water filters, under the sink models, or whole house water filters. You can pick from systems that use carbon filters, reverse osmosis water filters, and ultraviolet (UV) light technology. It’s great to have so many options, but how do you know which home water purifier is right for you?
Do You Need a Home Water Purifier?
The first question to ask when considering a residential water purifier is whether you even need one. If you have a municipal water source then your water is already treated. But many people don’t want to drink the chlorine or other additives that city’s use to treat water supplies. And there have been many instances when city water supplies have become contaminated despite treatment procedures.
If you feel secure about your city water supply and enjoy the taste of chlorinated water, then you may not need a purifier. If you’re not sure what’s in your water, you can ask to see a water quality report that all cities are required to provide.
Although well water isn’t treated, it comes from an underground source that can often be cleaner than municipal water. But if you live in areas with farming, manufacturing, and other industries that may inadvertently or purposely dump chemicals into the water table, your water is at risk.
Additionally, well water may contain sediments, such as iron, that can cause discoloration and odor. These sediments can also build up in dishwashers and other appliances and cause malfunctions. Many home water filters and purifiers can help improve the taste and quality of well water. To find out what type of impurities are in your well water, purchase a home testing kit or for more reliable results, have your water professionally tested.
What Contaminants Do You Want To Target?
If you’ve decided you need a home water purifier, the next step is to decide what type of contaminants you want to filter out or protect against. Are you concerned about bacteria and other microorganisms? Do you want to remove chemicals and compounds such as chlorine? Maybe you know your water contains sediments and high mineral content. Or perhaps like many people, you’re concerned about all of these things and you want a comprehensive home water purifier/filtration system.
Bacteria and microorganisms
If bacteria and other organisms are your targets, then you want to consider home water purifiers that use UV technology. Of the three most common water purification technologies, UV is the only one that effectively immobilizes bacteria. However, it does not remove sediments, chemicals and other contaminants.
Chemicals and sediments
Home water purifiers that use either carbon filters or reverse osmosis technology will remove suspended solids such as sediments, dissolved chemicals, and many other contaminants. Of the two, reverse osmosis is effective on a wider range of contaminants. However, neither of these technologies is effective at removing bacteria.
For a comprehensive home water purification system, it is important to combine UV technology with one of the other options. A carbon pre-filer is the most common choice. It’s also critical that you change your home water filters regularly and follow manufacturers’ maintenance schedules. If you don't routinely change the filters on your home water filters and water purifiers, you could wind up creating an even bigger problem with bacteria than the one you may be trying to avoid in the first place.
Where Will You Put Your Home Water Purifier?
Where you want to locate the filter/purification system can also influence your decision. Faucet mount and countertop water filters typically only come in carbon filter technology. You can usually find both carbon filters and reverse osmosis water filters in under sink systems. And both reverse osmosis and UV technologies come in whole house systems. Each of these can also be fitted with a carbon pre-filter for comprehensive treatment.
If your only concern is your drinking water, then you may prefer one of the many countertop or under sink water filters. They are less expensive than whole house systems, ranging from about $20 to $30 for a countertop pitcher or faucet filter to around $200 or $300 for an under the sink model. The under sink water purifiers are capable of processing water much more quickly, and the filters tend to last longer.
If you want to treat your bathing water and keep sediments and bacteria from building up in your appliances, then you will need to consider a whole house system. They start at around $400 for basic models and can cost upwards of $1000 for high-end systems. In the end, your budget may be the ultimate factor in your decision.
Installation and Maintenance
One final aspect to consider when choosing between different home water filters and purification systems is whether or not you want to install and maintain it yourself. Faucet mounts and countertop models basically require no or minimal installation. And the only maintenance is changing the filters, which is a simple process.
Depending on your mechanical aptitude, under sink models and whole house water purifiers may require professional installation and maintenance. Some companies require that their technicians perform all the work. The companies say this is to avoid mistakes and improper setup. Others say it is simply another means of charging more money.
But for those who don’t want to deal with the fuss and possible mess, a service plan may be well worth the extra money. In addition, a service plan often covers the equipment if it malfunctions or breaks down.
There are several factors to consider when choosing between the various types and styles of home water filters and water purifiers. The best place to start is with an analysis of your water. Different water purifier technologies target different types of contaminants, and a water test will help you determine which technology will meet your needs. Considering how much we depend on clean water for drinking, cooking, bathing and other daily activities, a home water purifier can be an inexpensive way to provide safe and healthy tap water for you and your family.

Many under the sink water purification systems have replacement water filter cartridges which need to be changed every 600 to 1200 gallons; unless there is a gallon-o-meter attached to the average person’s faucet, the number of gallons used could be somewhat difficult to determine.
One simple way to decide if it is time to use a replacement water filter is if the sink begins to loose water pressure; the sink will loose water pressure because the filter is clogged with dirt or other sediments. Depending on the microns the filter is able to keep out of the water some units may be washed out and reused for a time; usually if a filter stops less than 5 microns from escaping the filter, rinsing out the filter is useless.
A good rule of thumb is that an average household will use about 600 gallons of water per month from their kitchen sink for drinking, cooking, and cleaning; using the replacement water filter before the water actually starts to taste or smell bad is a good idea, however waiting until there are signs that the filter is loosing effectiveness is a good idea to prevent waste.
Whole House Units
Whole house water purification systems are the most practical for homes with hard water or contaminates which irritate the skin because impurities such as lead take a time to dispel with most whole house units and are treated more effectively using point of use or under the sink units.
Using replacement filters for whole house units is very similar to using replacement water filters for countertop/ under the sink units; the difference will usually lie in the amount of microns it filters. Whole house units in general allow more contaminates to pass to provide adequate water pressure for the entire home; as a result many of these replacement water filters can be rinsed out to prolong their usefulness.
Lessening water pressure is a good sign that the whole house water filer cartridge needs to be replaced; though these types can be rinsed out, it is a good idea to only rinse them one time before using a replacement water filter cartridge.
Also if a peculiar smell or taste returns to the water a replacement water filter cartridge is also necessary; most water filter cartridges will last for three or four months in whole house water filtration units.

A Guide To Aid Consumers In Choosing An Effective, Cost Efficient, Drinking Water Filtration Unit.
Purchasing a water filter in today's marketplace can be confusing even for the most savvy of consumers. Hopefully this guide will assist you in making the right choice in purchasing any water filtration system.
There are over 400 companies that sell drinking water systems for the treatment of various contaminants. Water filters vary widely in quality, price, and performance. Although hundreds of companies make water filtration devices that can reduce chlorine from water, only a few companies offer drinking water treatment units that are certified to reduce a wide array of contaminants of health concern.
A few companies or their representatives claim their products produce PURE drinking water. I have yet to meet such an animal. No water filter produces PURE water, but some do reduce numerous contaminants to a high degree. Avoid any brand that makes such false claims.
Water filters are like everything else, quality costs money. Quality drinking water purification systems usually cost a few hundred dollars to purchase, but save money in the long run because they produce drinking water for a fraction of the cost as compared to cheap filters.
Cheap filters do little or nothing as far as purifying drinking water. One thing they are good for is costing the consumer a lot of money in purchasing replacement filters. A quality filter will give you years of service and save you money. As a rule of thumb - If it costs less than - Let's say $200.00 - Put it back on the shelf. Do not worry, I am going to show you how you will save more than the $200.00....
Here are a few simple steps to purchasing a quality water filter that will be highly effective, cost efficient, and last for years.
Step 1 - Type Of System
Which application would be best for you - Counter Top - Undersink - Inline - or a Convertable type that can be used as a countertop or be installed undersink?
Counter Top Systems usually install by the use of a valve and rubber hose attached to your existing sink faucet. They do take up some space on the counter. Many people find this to be inconvenient.
Undersink Water Filters install conveniently under the sink and have their own faucet which should be installed at the corner of the sink. They save counter space. Sure beats having a monster sitting on your counter or a hose hanging off your sink faucet. This is the preferred type as it is not only the most convenient but can also be hooked up to an icemaker.
Inline Filters install directly in the line to any appliance that uses water such as an icemaking machine, coffee pots, water coolers, beverage machines, etc.
Convertible - Undersink/Countertop can be used as a countertop or installed as an undersink water filter.
Step 2 - Technology
Determine what you are trying to accomplish by using a water filter. Chlorine reduction only? Bacteria?
Or, do you want to effectively reduce bacterial cysts, chlorine and a wide range of chemical and organic contaminants at the same time. This is what a quality water filter can do.
Another thing to consider is - Do you want to remove the "Healthy Minerals" from your water? Minerals are good for your teeth and bones.
There are a number of different technologies when it comes to water purification. Here are some examples -
Loose Carbon - This is a bacteria factory. Loose carbon allows oxygen to exist within the filter itself which encourages, infact, enhances the growth of bacteria. These filters are very cheap to purchase, but expensive in the long run because the filters have to be replaced frequently.
Distillation - Can be effective on bacteria, sediments, solids, and any organic or chemical contaminant that will not evaporate. There are some chemical contaminants found in water today will evaporate, MTBE is a good example.
Ultraviolet lighting is sometimes used in conjunction with a filter to kill bacteria and has been found to be effective.
Reverse Osmosis - A membrane which reduces radium, fluoride, and numberous other contaminants to a high degree, but it does have it's limitations. There are many contaminants found in water today that will pass through an RO membrane. Reverse Osmosis used in conjunction with a high quality filter can be very effective. Reverse Osmosis does remove the "Healthy Minerals".
Reverse Osmosis alone is capable of reducing a number of contaminants found in drinking water today. Arsenic, barium, radium, giardia, cryptosporidium, entamoeba, fluoride, lead, nitrates, nitrites,
selenium and a few others...
Solid Carbon Block - This type of filtration reduces the widest range of chemical contaminants to a very high degree. Some are higher quality than others. The density and high quality of the carbon determine the effectiveness. Water passes through a high quality solid carbon block as a molecule instead of a drop. This means all the water touches the carbon. Therefore all the water is subject to proper filtration. Look for a carbon block which will reduce contaminants to at least 1 micron, preferably 0.5 micron. The smaller the number the better.
Any high quality solid carbon block will reduce a wide range of contaminants. Contaminants such as
lead, bacterial cysts, mercury, asbestos, mtbe, and many others.
Step 3 - Performance
Performance is the key factor. Actually the most important thing to look for in any water filter. Don't waste your money on an ineffective water purification system that simply does not work.
****Carefully read the packaging. Determine which contaminants the manufacturer states the filter will reduce. The label on the product package should state exactly which contaminants it is capable of reducing based on standards set by NSF International.
**** So how do you know if the claims made on the label are correct? If the filters is not certified by the National Sanitation Foundation, put it back on the shelf. Quality water filter manufacturers put their filters through rigorous testing by NSF and are proud to advertise their certification.
**** NSF International tests and certifies drinking water treatment devices to the standard appropriate for the technology of the product. For filtration devices, NSF International may certify the product to improve the aesthetics of the water to Standard 42, the health effect of the water to Standard 53 or both. In addition, NSF has developed an additional testing standard for Reverse Osmosis units, Standard 58.
One other thing I want to mention, be sure the packaging states NSF Certified To Standard 53 for example. If it says "tested to NSF Standards" - This does Not Mean Certified.
If you want to see the actual certification, go to the NSF website: www.nsf.org - Click the consumer block and put in the make and model of the filter. If the filter is actually NSF Certified, you will be able to view the contaminants tested for and certified to remove. This way you can compare different certified filter's performance.
Step 4 - Cost Efficiency
Quality water filters have a long filter life capacity. This is what Saves You Money. Look for a water filter that has a capacity rating of at least 6 months. Understand, this is an estimate. The actual life of the filter depends a lot upon the qualities of your water. If your water has a lot of solids the filter will clog sooner than it is rated. If your water has a high level of contaminants, it will become ineffective sooner. In most cases though, the filter life rating is conservative, meaning the filter will actually outlast the capacity rating. Always keep the filter changed at the recommended intervals, even sooner if possible.
Cheap ineffective filters actually cost more to operate. Having to frequently change the filter cost a lot of money in the long run.
I hope this article helps you in your quest for a quality water filter!

Water filters are available in a huge and sometimes confusing range of types and prices. The technical terms used are sometimes confusing and before making a major purchase you should satisfy yourself that the water filter has a large enough capacity to handle all your drinking water needs.
Home Water Filters vary from simple jug or bottle filters with a basic charcoal filter up to serious water processing filters that will produce crystal clear water of far higher quality than municipal tap water.
Cost is a major factor of course but there are some outstanding bargains in home water filters.
Remembering your budget, think about how much you spend every week on bottled water. Bottled water comes in either 2 litre or 5 litre plastic bottles and according to which plastic the bottler uses can have a strong taste from the plastic material. Many brands of bottled water are just bottled tap water. Municipal tap water normally contains various chemicals and possibly micro-organisms
The average family drinks from 30 to 40 litres of water every week and that works out at over $1500 a year! That is for basic supermarket bottled water รข€" Fancy imported water would double or treble that cost. That would buy a pretty fancy tapwater filter.
Here is a breakdown of the different kinds of water filter available:
Jug type water filters - commonly the Brita is the most popular and is a good choice as it comes with a good filter cartridge. It is possible to use cheaper supermarket cartridges but these often leave an after taste and do not last as long. There is a counter top model which uses the same Brita filter and has a larger reservoir for filtered water/Filters last around 2 months. Most jug type filters are designed to fit into a refrigerator door. Lids on this type of filter are sometimes fragile.
Cartridges are widely available.
Refrigerator Filters - these are plumbed into a refrigerator.This is an easy to use filter that needs to be change every 6 months. Main advantage is that cold drinking water is always available on tap
Under sink water filters. These are plumbed in to your kitchen faucet and provide clean water on tap. They have the disadvantage of not removing micro-organisms. Should be changed every 2 or 3 months, Cost around $30 for new cartridge. Some units have a charcoal and a ceramic cartridge and the charcoal cartridge needs changing regularly. The Ceramic cartridge needs cleaning and can normally be reused.
Multi stage filters. These are usually a multi part filter system which may have three different filters. These are usually pumped systems so they need an electricity supply. First is a sand or gravel filter that removes organic matter (peat etc) next is a charcoal filter which cleans larger particles and is followed by a ceramic filter that filters out many micro-organisms. A refinement to this type of filter is a UV (Ultra Violet) filter that kills microbiological creatures like Giardia and Cryptosporidium which are the two main causes of stomach upsets from the water supply. Multi stage filters are basically similar to the filters used to filter water in aquariums for tropical fish but are on a larger scale. They can also be fitted as under counter units.
A further advanced filter is called the reverse osmosis filter. Although this filter produces excellent quality water, but the process is rather slow and can take a time to process enough for a large family.
Whole House Water filters are much larger but work on the same basis as multi stage water filters. They are correspondingly more expensive and many whole house water systems are designed for different house sizes. These will filter all water coming into your house and can also be incorporated with a rainwater collection system to cut down your water costs and needs. Think about how many bathrooms, toilets and water dependent machines you own (dishwasher, washing machine etc)when making your decision.
Advances in water filtration are always being made but these are the basic categories of water filters currently available

Respond Swiftly! Use Drinking Water Filter Systems For A Fitter And Better Life
0 comments Posted by ariya at 22:46Although these contaminants in the water are controlled by rigid government restrictions, folks who are worried about these issues can rest easy with the many fantastic water filters obtainable. The reputation of bottled water has grown during these past few years as a result, though unlike water filters, these are not regulated. So families are looking towards drinking water filter systems in their homes.
There are three basic types of filters on the market: regular, carbon, and reverse osmosis. These three types have the capability to eliminate around 99% of contaminants and bacteria in the water. A regular pitcher type filter is surely the one you need if you want something less expensive and it works by filling with tap water, while it filters down into the pitcher.
Ordinarily, pitcher filters fit in behind the refrigerator door, making them simple to set up. Brita is the cheapest brand, and they have filters that can be recycled. Brita is certainly the selection if you want to go environmentally friendly. Pur filters out lead much better than Brita.
On the consumer index, Pur III pitchers and faucet attachments have the best score. At $25 or $30, they are much more costly than Britta, but they are far better. Pur drinking water filters typically have carbon, allowing for the most effective filtration process and each filter has a graded system, letting you comprehend when replacement is needed.
Under the sink carbon block filters are becoming more well-liked, particularly in the newer homes. Considered to be the most effective, Puriclean has continually acquired high ratings in many assessments. Unlike most faucet attachments, the Puriclean can function longer, it is convenient to put in and change, and it costs about $30 to $60.
Among all the refrigerator filters, Puriclean has the highest rating on the consumer index. These are easily replaced every six months and have a sticker to put so you will remember when to replace the filter. Carbon blocks are found in these filters.
Another widely used brand of refrigerator filter is Kitchenaid. At $40 apiece, this brand of water filters includes simple renewal after every six months of use. Despite the nominal scores, these are nevertheless great filters to look into.
The most effective brand accessible is Pentek, with the carbon block, for the refrigerator. Several contaminants can be easily taken away from the water, such as microorganisms, metals, sediment, corrosion, and iron. Pentek also includes deionization reduction, which lessens water salinity.
Pentek has numerous other filter types, like the faucet filters and the inline filters, aside from the refrigerator filter. Many families are becoming aware of the assimilation of toxins in the shower and bath water and prefer to put a filter on the point of entry.
Several features, like reverse osmosis, ultra violet reduction, and bacterial and viral reduction, are also provided with Pentek, which are great for both commercial and residential applications. When eliminating all types of metals, poisons, bacteria, and viral contaminations, reverse osmosis is the best water filter system available.
In line with many doctors, a number of illnesses are increasing because of large quantities of heavy metals and poisons in the body. Though these can be obtained from the atmosphere and foods, water, as well as terrible drinking water filter systems, are the primary sources of this concern. Filtered water systems are obtainable for our better health, and they are worth the investment.
When it comes to fridge water filters, you and your family can seriously profit a whole lot. Whether it's better tasting and smelling water, better wellness, or better savings, you can gather a lot by having one setup in the kitchen or even around the whole home.
