Product review (3 stars): Ok, but I have found better
I was ordering these filters pretty regularly for a while but have stopped. The water quality itself was ok, but they simply do not last that long.

The water quality at my home is not the best in regards to being hard and the properties of various elements. I bought some different filters and had the chemist at work run both samples of water with each filter and there was literally no difference. The big difference came with the lifetime of about 2 1/2 months longer with the other filters.

When this filter starts getting royally clogged, my ice maker starts knocking like a bent rod in a 400. you can hear it across the house.
