Product review (4 stars): Works but Pricy
Fits and works.  No drips.  When ordering, be sure to pay attention to the type your Whirlpool company brand requires - there are at least 4 distinct types (Type1, 2, 3, 4)...  It is certified to remove 23 contaminants. A bit of an overkill for us as we have very pure well water that is tested annually - its just like rainwater with miniscule minerals.  But might as well be extra safe.  Using this brand is a bit on the expensive side.
