Pool filter cartridge reference

Specified correctly, the first time.

Meridian Filtration publishes complete dimensional specs and cross-reference data for replacement pool filter cartridges, so you can confirm the fit before you order.

The same cartridge is sold under a different part number by nearly every brand that makes it. A Unicel C-7470, a Pleatco PCC80, and a Filbur FC-1976 are the same physical part for the same filter. That inconsistency is why pool owners order the wrong cartridge. The reference pages here resolve it, part number by part number.

Start here

If you have a part number in hand, go straight to its page for specs, verification steps, and the full cross-reference. If you are not sure which cartridge you have, start with the fitment guide.
