Product review (5 stars): Perfect
in response to the ongoing debate in the ratings, my filter paperwork lists it as 42/53 filtration.  filled it with water and drained it as instructed. installed in minutes, ran about a gallon of water through it after installation.  water appeared clear from the start. no unusual odors or taste.  water flow improved immediately from the slow trickle with the old filter.  6 months now, and every thing is fine.  haven't had to contact customer support, but they have contacted me twice by e-mail to ask if had any questions or problems, so seems as though they would be quite responsive to any problems. can't see how product or distributer could be any better.
