Koch Replacement Filter Cartridges

This page lists 48 replacement filter cartridges for Koch part numbers. Most use a coded format that starts with C, such as C11H127-316, C33H127-110, C44A145-406, C55A142-502 and C88H127-215.

These numbers are long, and one letter or digit can mean a different cartridge. For example, C11H127, C11E127 and C11A127 are separate parts, and C11H138-324 and C11H138-325 are different listings. The page also has a few numbers in other formats, including K10-1498 and the 304-series numbers 304-121-006, 304-121-009 and 304-122-005.

The safest way to order is to copy the number straight off the old cartridge or from your parts list. If you only have part of the number, or yours isn’t listed, call 562-436-4228 or email info@industrialfiltrationinc.com. Industrial Filtration has supplied filters since 1956, and we can help with the cross-reference and a quote.
