Product review (5 stars): Help fixed the water pressure problem with my ice maker beautifully
So far so good.

I did not realize how important changing a water filter could be on my fridge.

Apparently my water pressure had gotten so low that it was causing problems with my ice maker. (it froze up)

I got this (which appears to be the named brain) and it worked beautifully.

My cups filled A LOT quicker and after de-icing my ice maker, it started filling the fridge with ice again. I waited 2 years before changing the one that came with the fridge... I probably should have changed it in about a year.
