Product review (2 stars): Expensive
This a necessity but I think that's where they (GE) get you. I've looked at the generics but have been scared away by horror stories of leaking. There's no real way to know if it really needs replacement. The built in "timer" in the refrigerator that says it's time to change. It registers the same as my neighbor with 3 kids!  There's 5 in their family and just me in my household. Both of our filters expire at the same time. GE must think we are idiots.
