How to Choose the Right Water Filter

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!
