I am one that is very picky about how my water tastes and won't drink enough if it's not good. After trying multiple filters I came across PureEffects and haven't looked back.
I have been using this for a number of years, it moved with me and we added another sink in a remodel so I have 2 in the house now. Plus we bought the 2 version (not quite as wonderful, but still so much better) for our RV.

It gets a little expensive, but worth it for our health. Helps our coffee taste so much better too!
