Product review (5 stars): Great product
I have purchased these in the past at fridge filters.com, but amazon's price is better.  I have used these filters for the past 11 years and and have been happy.  GE thinks we need to change our filters every 3 months, but since it is just the 2 of us at home, we can easily get 6-8 months out of a filter.
One of the clues that the filter needs to be changed is that the water flow from the refrigerator dispenser slows down quite a bit!  To give you a frame of reference, a fresh filter will dispense 3 qts of water in a minute, and I usually change the filter when it takes 2 minutes.
I like the taste of filtered water, and also use it in our Keurig (which helps keep the Keurig filter unclogged, because that is a pain in the neck to clean).  I easily use 3 qts of water a day, more in the summer. Even the yucky taste is gone that we get in the summer, when an algae bloom on the reservoir water grows from the intense heat.

I found the filter instructions easy to follow, as even I was able to change the filter myself without my husband's help!  Just remember to do as they suggest and run through the first 3 qts of water and then dump it.

One last trick is that I mark the filter with the date of installation so that I know at a glance if I am nearing the time to change filters and make sure I have one on hand.
