Product review (3 stars): Not as good as PUR
I don't know why, but the PUR filters are harder to find for refrigerators. I guess Whirlpool is gradually phasing them out in favor of their own brand. I flushed about 5 gallons through my new Whirlpool and the water doesn't taste as 'clean' as the older PUR filter. I'd compare it to the plastic taste derived from a cheap plastic bottle of Vodka. I'll splurge for the PUR next time.
