Product review (5 stars): Also fits some Kenmore refrigerators
My mother needed a replacement for her Kenmore refrigerator and I noticed it was the filter looked just like this and even had PUR in small print.  This filter fit perfectly (it was identical to the old filter, just a different label).  Sears doesn't really make anything  (I recently had problems with another Kenmore appliance and Sears told me they didn't make and I should complain to the manufacturer), so I was very happy to buy this at a lower price from Amazon rather than being force to buy it from Sears.  You should always try to figure out who made any store brand appliance you own (humidifiers, air filters, etc.) since it is nearly always possible to get the identical replacement parts cheaper on Amazon.
