The Filbur FC-3910 30 Sq. Ft. Spa and Pool Filter Cartridge is a compatible replacement for the Hot Springs 31233, Unicel C-5431, and Pleatco PKW30V cartridge filter models. Noted for its swift capacity to ward off bacteria, mold and fungus, as well as its ability to reduce breakage and tears, this swimming pool filter is a viable opponent to other competing models on the market. One of its most celebrated assets is its rare compositional structure, comprising interlaced Reemay filter material and threaded inserts, all of which are strategically engineered to sustain the conditions of spas and pools.

This spa filter model features antimicrobial end caps that resist the entry of bacteria. This conserves the framework of the cartridge itself, allowing for prolonged use. This pool filter cartridge fuses the complementary features of breakage-resistant bands and a PVC center core.
