The [Culligan IC-EZ-1 Inline Icemaker and Refrigerator Filtration System](https://www.amazon.com/s?k=Culligan+IC-EZ-1+Inline+Icemaker+and+Refrigerator+Filtration+System&tag=thetestedhub-20) was my top pick because the quick-connect fittings made install painless and chlorine dropped to undetectable on test strips.

The Filters I Tested

I plumbed five inline water filter systems into my fridge and ice maker lines to find which ones actually improve taste without slowing flow.

Questions answered

How long do inline water filters last?

Most last six to twelve months depending on water quality. My city water pushed them to nine months before I noticed flow drop.

Do inline filters reduce water pressure?

Slightly. A clean filter loses about five percent flow. A clogged one can cut flow in half, which is your signal to swap it.
