These filters do what they say they will. They really do filter out unwanted particles and leave good, clean, delicious water.  For those that complain about having to replace the filter frequently, that is not a product defect or negative but a positive because the filter is doing what it is supposed to do.

I also like how easy these filters are to replace and install.  I like that you don't have to soak these in water and go through a tedious pre-install process.
