Product review (5 stars): exact replacement for 4396508
due to reviews on this site about mismatch between this filter and the one it replaced, 4396508, i decided to buy it from my local home improvement store - in case it didn't fit, it would have been an easy return. i found the Everydrop EDR5RXD1 to be an exact match for the filter it replaced, 4396508 (the tip was not longer, it is the exact same length). of course, you don't have to take my word for it, you can check for yourself.
