Pleatco Replacement Filter Cartridges

If you've owned a hot tub or pool in the last twenty years, there's a good chance Pleatco has been quietly inside it. They're the largest cartridge manufacturer in North America and the OEM supplier for plenty of hot tub brands you'd recognize: Beachcomber, Jacuzzi, Caldera, Sundance, Waterway, Bullfrog. The original cartridges those brands ship are often Pleatco-made, just rebadged with a different sticker.

Pleatco's "PRB" prefix (short for Pool Replacement Brand) has become the de facto cross-reference standard, which is why every cartridge on this site lists its Pleatco number first. All 49 cartridges below are Pleatco originals with their full Unicel and Filbur equivalents.
