Product review (5 stars): I've Been Using This Brand For 8 Years Now - Always Works Great
I've been using these GE MWF refrigerator water filters since 2007 and I pretty consistently get about 9 months out of them.  This might be due to turning off the ice maker for a day or two at a time, then turning it back on only when the ice is getting low.  When replacing a filter, I always mark it with the month and year of installation.  Never had a problem with any that I've bought over the years.  I'll be back to buy more next year.
