Has the AquaRain been laboratory tested?

Laboratory Testing

Extensive independent testing is the key to proving the performance of any water filter product. The ceramic filter elements used in the AquaRain Gravity Water Filter have been thoroughly tested by government agencies and independent laboratories. Our unique ceramic structure has been successfully tested in independent laboratories with Cryptosporidium parvum for cyst removal, and the EPA mandated Klebsiella terrigena for bacterial removal. These elements have also been successfully tested against the Health Industry Manufacturing Association’s test organism, Brevundimonas diminuta, which is approximately one-third the size of the EPA bacteria test organism. It is notable that all of these tests were performed at 60-90 p.s.i. which is far above the very low ½ p.s.i. found in our gravity operated system. This equates to an expected performance in microorganism removal far beyond the results already achieved in our laboratory testing.

What is particularly noteworthy is that all of the above laboratory tests have been performed with fully expended elements, ready for disposal. All components for testing were abraded to 10% below their end-of-life tolerance and then exposed to contaminated field water prior to being challenged in laboratory testing. In every case, AquaRain Ceramic Elements surpassed the stringent EPA standards for a bacteria and cyst purifier.

We have gone the extra mile to insure that our product will perform as promised and remain effective in producing safe drinking water throughout its entire life. To the best of our knowledge, no other manufacturer has dared to test in this way and publish the results of this type of end-of-life testing.
