Product review (4 stars): It was fine for a few weeks
After the price hike, I tried a cheaper filter.  It was fine for a few weeks, but then the water started tasting funny.  So, back to the MWF filter.
Can't beat it for filtering performance, but I knocked a star off since GE felt the need to jack up the price.
And what is the deal with multi packs being more expensive than buying multiple single filters?
