Product review (5 stars): Replaces the 4396710
A five star review equals "I love it" by Amazon's standards. I can't really say that I truly "love" a water filter, but I'm really glad I found this one. I had been searching for the 4396710, which didn't seem to exist anymore. Apparently Whirlpool replaced their numeric line with the EveryDrop and didn't bother to make a public service announcement or send out a change of address mailer or anything. I had bought some terrible Chinese knock-off, which I highly advise against, mostly because mine didn't exactly fit (it was about 5mm too short) and got lodged in the refrigerator. I had to use pliers to pull the knock-off filter out because I broke the cap on the first attempt. Thankfully they sell the caps on Amazon too.
