Product review (1 stars): Didn't work
Bought the 5 pack and opened and installed one and the water would not flow no matter how many times I reseated it. After comparing my old one to the new one I noticed that there was only the hole in the middle and not any other place for the water to pass through the filter like the old one. It was basically blocked one way with no way for the water to enter or exit (not sure if the hole in the middle is the in or out) through the filter. Didn't bother opening any other ones to try and started the return process through Amazon. Old one worked fine as soon as I put it back in. Not sure if it was a manufacturers defect or what but it's a basic mistake.
