Product review (1 stars): Bad, bad, bad! Short life, bad taste, no value in being "green".
I bought a couple of these filter back in early 2014 as replacements for my whirlpool 4396510 filters.  As I am an Engineer and like data, I always write the date on an item when I install it like light bulbs) so I can get an idea of how long they really last. So the genuine whirlpool filter I removed on 4/16/2014 said I installed it on 11/29/2012 (16.5 months).  In goes my first SGF-W01 filter and I drop the old one in a drawer.  A few months later my family is all complaining the water tastes bad and I have noted an off taste myself.  The fridge says it is still ok, but I replace it with the second Swift filter on 12/02/2014 (7.5 months) and dropped the used one in the drawer.  Now I just had to replace it again based on the sensor in the fridge on 5/01/2015 (6 months).  While these were cheaper than the whirlpool filters when I originally bought them, they now cost more than I just paid for two genuine whirlpool 4396510 filters on Groupon. And the fact that they only lasted 6-7months vs 16 for the genuine filters, shows these are cheap knock offs and offer no value to the consumer other than some slick marketing saying they are "green" (but they are still in a non-recyclable plastic housings...). Don't buy this junk.
