Product review (1 stars): DO NOT WASTE YOUR MONEY on this!
Not only does this filter NOT REMOVE ANYTHING, IT ADDS CRAP!!

TDS meter readings on water from an OLD FILTER attached to the sink: 181  (Obviously, that filter is bad and we never use it).

TDS meter readings on TAP water: 134!!

TDS meter readings on the water FILTERED WITH THIS GE MWF FILTER: 149!!!  Not a typo, that's 149!!

It's WORSE WITH the filter!!  WTF??  No wonder my cats won't even drink water filtered by this filter!

Meter is an HM TDS-4 (sold here).

I'm getting a refund, total waste of money.
