Product review (5 stars): Great Filter for Whirlpool ED2SHAXMT00
There were a couple filters for my refrigerator, a Whirlpool ED2SHAXMT00, however this was the only one that actually filters impurities it seems.  The previous owners of my place had these Chinese off brands or whatever, and they made the water taste like rust.  This made it taste like water again, and they do last for almost exactly 6 months.
