Product review (1 stars): Doesn't filter anything!
I have 2 GE refrigerators, both under 2 years old.  I purchased 2 of these replacement filters...and an HM water meter, to see how good the the filters work.  To my extreme surprise, the water filters remove nothing from the water, the contaminent levels are equal with the tap water in each of my two houses!!!  I ran gallons of water through the filters and the readings never went down.  So I called GE, customer service informed me there was a small chance I could have received 2 defective filters, and I should try to return them to Amazon.  I tested the HM water meter on bottled water that is supposed to be very pure, and it was.  Arrowhead water is at a "marginally safe tap water" level.  My neighbor's reverse osmosis worked well. (I highly recommend everyone get a water meter...especially if you are putting any kind of trust in these GE filters!).
