Find the part number printed on your old cartridge in the Compatibility tab. If you cannot read it, measure the outside diameter and the length, check both end caps, and compare them with the Specifications tab. A difference of about 1/8 inch is normal; more than that usually means a different filter model. Matching measurements alone do not prove a fit: some of our cartridges share a size and differ in filtration area or end caps.
