Review on Enhance your Filtration with FRIZZLIFE M3003 Replacement Filter Cartridge by John Koch

I live in a modern city and our tap water tastes very bad, very chemical. My wife and our cat refused to drink it until I bought Frizzlife. On city water, my use of the filter is completely opposite to what is written on the manufacturer's website. I use 3rd level at 1 month, 2nd level at 4-6 months and 1st level at 6+ months. I know it's time for a new 3rd stage filter when the water isn't "sweet" anymore. It's not actually a sweetened sweetness, but I don't know how else to describe it since clean, pure water is so hard to come by these days. I love these systems, but I will say that my dear old lady could not change the filters due to the tight fit of the cartridge on the body.
