Softub, Dolphin, Leisure Bay Spa Filter Cartridge 25 Sq Ft FC-0305

These replacement spa and hot tub filter cartridges are identical to Filbur part number FC-0305, Unicel part number 6CH-25 and Pleatco part number PTL20W-SV-P-4. These filters are constructed with thermally bonded polyurethane caps and a punched PVC pipe core that will ensure consistent water flow through your filters along with the durability you depend on.

To clean your spa filter remember these 4 simple steps; rinse, soak, rinse, dry. Rinse your filter out with a garden hose to remove any debris or dirt still attached to your filter. Next, soak your filter in a filter cleaner solution overnight then remove your filter from the solution and rinse with a garden hose. Set your filter in a sunny location and let it air dry completely. Finally, reinstall your spa filter per your manufacturer's instructions.
