Product review (4 stars): Wife not satisfied compared with favorite bottled water.
received  the 3 pack, promptly installed one as per instructions. Passed 3 gallons of water before we started using as drinking water. Discarded the first 2 bins of ice as well. The municipal water tastes much better and the bad smell it had has disappeared  as well. I am satisfied with the taste, its almost the same as our favorite bottled water, but my wife is not convinced, she says that it could taste better. I know your filters are nsf 42 certified, but do you have a nsf 53 filter? I think she will not be satisfied unless I instal a filter that is both 42 and 53 tested and  certified, not just one that meets the standards .
