Overview

Harmsco BetterFilters are electropolished stainless steel housings that hold reusable pleated cartridges, so a pool can be filtered without backwash water or a waste line. The BF-Series holds 7 to 50 cartridges and handles up to 450 gpm per housing at 50 psi in a footprint of roughly one to two square feet; the BF-SC single-cartridge housings serve smaller pools and spas.
