Product review (5 stars): LEARN from my mistake - Dont buy a knock off filter
Waaaaay better than the last filter.
Tell me if this is you.  Hmmmmm that name brand looks really expensive, Im going to buy the off brand.  Probably made in same factory and just dlsp a different label on it.  I do that sometimes and sometimes I am right and then sometimes I end up costing myself even more money than if I had just bought the name brand to begin with.
I bought cheap fridge filter On Amazon a few weeks back.  I experienced these stringy globs in what was supposed to be our filtered water.  I kept running water through it hoping it would clear up, but it didnt.  So I removed the cheap filter.  The family was all upset because no cold water or ice.  I was not popular around the house.
I installed this new filter in seconds and ran a few gallons of water through the system and what do you know - crystal clear water.
