Product review (5 stars): Long lasting, easy install
This was the first replacement for the new refrigerator.  I was nervous about what might go wrong like with Whirlpool fridge.  Absolutely no problems, easy breezy to remove the old.  It is filled with water, so keep upright and drain in sink.  Add some water to the new and align the arrows, push up and slightly tighten.  No drips.  Then purge the air from the water line by pouring off about 1 1/2 gal, or until no pops of air in line. This filter is good for approx 500 gallons. We have high chlorine taste in tap, and this filter makes it fresh as rain water.
