Cartridge filters provide premium filtration. Cartridge filters also save on water consumption because they never have to be backwashed! Every piece of organic particulate (dust, dirt, skin cells, and other contaminants) gets trapped inside your cartridge filter month after month. At least every six months your cartridge filters need to be cleaned to eliminate the organic build up. McCallum’s pool service completes a full inspection of the filtration equipment and oring associated with your cartridge filter each time we service your equipment.
