Product review (4 stars): these filters work fine as replacements for the no longer available PUR 4396841
Functionally, these filters work fine as replacements for the no longer available PUR 4396841. I have replaced two of them over the past year with no installation issues, leaks, or other problems. I have never had a problem with them leeching charcoal into the water and ice like as some of the cheaper replacements here on Amazon have been reported to do, and the water and ice always taste great to my palate. My biggest gripe here is the price. I was able to source the PUR replacements here on Amazon for $57.98 for a 2-pack, and the over $30 increase is a bit of sticker shock. Now supposedly these new filters take out more contaminates so maybe that is how they justify the price increase. If you live in an area where the water is particularly nasty maybe it is worth the difference. Still, I am one of those people who doesn't buy off brand replacement cartridges for my laser printer, so I'll probably stick with these Whirlpool filters in the future as well.
