Bought a water tester to test my newly installed 6ppm reverse osmosis system. Tested bottled water: 20 ppm. Fridge water: 150 ppm Tap water tested: 200 ppm This filter: 200 ppm. (3 months of light use as of test date) I felt like my $99 purchase was in the closet. I suspect it doesn't actually filter anything.
