Quality Water Filters 4 You Posting Page
Wednesday, May 5, 2010
So, you decide you want to protect your family against the harmful effects often found in tap water. You decide that buying bottled water is simply too expensive and cumbersome. After some research, you decide that installing water filters is your best and most affordable option. But how do you know if water filters you are considering are reliable? There is an easy way to determine which water filters are going to be effective and which you should steer clear of. It is called filter certification.

It makes no sense to purchase a water filter if you cannot feel confident that it is performing the tasks you want it to perform. The simple truth is water filters are not all the same. Some perform certain tasks, while others perform other tasks. You need to know which is which before you buy. It is also important to buy filters that have been tested and rated and certified as to their effectiveness and reliability.

There are three types of certifications that you can look for on water filter labels. Filter labels will also detail what the filter can and cannot do. It is important to read this information before you purchase. In the event you come across a water filter that has not been certified, you should either bypass that model or you may want to contact the maker of the filter to get more information.

The three organizations that provide certification for water filters are all accredited by ANSI (American National Standards Institute). Before a water filter can be certified, it must first undergo a series of tests. Some of the issues that the filter must pass before it is allowed to be certified include: verification that it does, indeed, reduce or remove the contaminants that it says it removes or reduces; physical testing of the unit to see if it holds up under normal wear and tear; inspection and testing of its internal parts and filter media; and other performance tests.

In order to receive its certification, the unit must meet or exceed the ANSI and EPA standards for drinking water.

Here are the three certification organizations that you want to look for as you choose your water filter. A product does not need to be certified by all three, just one.

Underwriters Laboratories: World famous and with a long history, Underwriters Laboratories, Inc., is an accredited and independent testing and certification organization.

NSF International: The NSF Water Treatment Device
Certification Program conducts intensive product testing on water treatment devices. They only certify products that have met or exceeded national standards for materials, design, and performance requirements.

The Water Quality Association: The WQA is a trade organization that conducts extensive water treatment device testing. It awards a Gold Seal to those devices that meet or exceed ANSI/NSF standards for water contaminant reduction performance, material safety, and structural integrity.
