To Whom it May Concern:

We have been using a ForeverWater purifier in my laboratory for several months now. We are extremely pleased with its performance. There are eight scientific researchers in my lab, both predoctoral and postdoctoral scientists. We conduct biomedical research. Our research requires 2-3 gallons of ultra pure water a day for performing a wide variety of biochemical reactions including molecular biology analysis of protein, DNA and RNA, and preparation of media to culture cells.

Prior to purchasing a ForeverWater purifier, we were using a Barnstead reverse osmosis filtering system. We were dissatisfied with the quality of water from the Barnstead unit. We experienced periodic experiment failure due to poor water quality. However, since using the ForeverWater purifier, which we are running on straight tap water, we have experienced no experimental problems attributable to poor water quality.

We have been using water from our ForeverWater unit in all of our experiments requiring pure water. We have specifically tested its performance in experiments handling RNA, protein and DNA. We have observed no degradation in any case. We have also tested it in enzymatic reactions involving RNA, DNA and protein with perfect success.

In summary, I recommend the use of a ForeverWater purifier to anyone conducting biomedical research. I enthusiastically endorse this product and am currently recommending it to my colleagues at Oregon Health Sciences University.
