Product review (4 stars): Quality Skeptic
Bought a two pack and tried one in our LG fridge.  It seems to work OK.  We have a lot of iron in our well water.  Unfiltered, it stains the toilets with rust.  The ice cubes look clear and taste good.  I only gave this four stars because I believe this filter only removes impurities of five microns and above.  I believe an original equipment filter removes impurities down to two or three microns.  That's probably why they cost more.  Someone set the record straight if I am wrong.  They don't advertise this important specification in the product summary.
