Product review (1 stars): 6 consecutive failures
The filter that came with the new fridge lasted nearly a year before water flow slowed to a trickle. Ordered a replacement from this site. It started out fine, but slowed to a trickle within a week. No hassle exchange. But same problem repeated. And repeated.

So we got a refund instead of another replacement. Purchased next replacement at W-Mart. Same problem.

Contacted GE. They were quick to send someone out. (The fridge was still under warranty for a few more days.) GE diagnosis: somewhere in our 10-year-old house, we had a backflow problem. Either that or sediment was getting into the local pipes. Second theory seemed shot, considering that none of our neighbors experienced such problems. Also: none own GE appliances.  In any case, GE guy gave us a new replacement filter, no charge, along with a recommendation to open all our taps for an hour to flush out sediment before installing the replacement. We followed his Rx (a sin in this arid land) but we experienced the same problem a week later.

So, suspecting backflow problems, we called in a plumber, who, after an hour inspection and a $62 fee, determined there were no possible avenues for blackflow. His diagnosis cast our suspicion back to city water. (We are gullible sometimes.)

Talked with a guy there--one who was unusually knowledgeable and caring (by city-employee standards)--but this problem had him stumped. In the end he recommended an in-line filter to pre-filter the GE filter. So we installed one, and then ordered yet another GE filter. This one lasted 6 weeks, then eventually slowed to a trickle.

Why did the filter that came with the fridge last so much longer? Why did all of the replacements fail so quickly? Does it even matter anymore?

You decide if it's worth the trouble.
