Product review (4 stars): Long-lasting water filter
We have used these filters since our GE refrigerator was purchased new 6 years ago.  They have provided us with clean, odor-free water.  We change them when the "replace filter" light comes on. We usually get 9 - 10 months of use from each one.

I've always considered the filters to be expensive, so when I run out I always buy a 3-pack to lower the cost/filter, and I shop Amazon to get the best price possible.
