Product review (1 stars): IFFY buy at best.
These filters, well the first one out of a 2-pack, worked as expected. They are not the same physical size as the former Whirlpool PUR filters. The second filter was installed November 1 and the water tastes of chlorine. The old filters were fine and cost the same and I could rely on them. When I called EveryDrop they told me only warranted for 90 days and only if you bought the filter from their website. They also tried to blame on local water provider using more chemicals than usual possibly.  Either these filters aren't the real thing, or EveryDrop quality is a lesser quality than the former Whirlpool PUR product, which are now nowhere to be found. Buy at your own risk! You can't return to Amazon and EveryDrop won't help. Even though first one worked well, I'm giving this rating because of the crappy way EveryDrop acted.
