Product review (2 stars): Not buying the 2-pack again.
I installed one of the filters from the 2-pack and the water ran extremely slow and inconsistent. I put up with it thinking it would get better. Nope! So I opened the second filter from the 2-pack and installed it, then the water ran normally! Unfortunately, I waited too long for the first filter to get better and missed the return/exchange deadline. Now I have one bad filter and one good filter. Bum deal.
