Product review (1 stars): Not an exact replacement of old filters.  Does not fit!
I have bought the PUR Whirlpool filters since we bought the fridge back in 2009.  Now they've been replaced by the more expensive Every Drop filter and it doesn't even fit!

I tried for a while to figure out why it won't go in all the way, because at first, second, and third glace, they look exactly the same.  I even got out some calipers to do some measurements and trim what I thought was some slight excess, thinking that might help.  Nope, still wouldn't click all the way in.

Finally noticed at the end that where it clicks in that all the way around there is a tapered end on the new filter.  The old filter is all flat until the end.  Sure enough, where I tried to put it in again, I noticed that's where it stops from going in all the way.

Seriously?!?  Not only does the manufacture take away what has always worked, but replaces it with what I and many others can't use.  What can I do now about filtered refrigerator water besides try my luck with possibly shady third party filters?
