The Tier1 DPFPCC0021DTL-2PK is a 2-pack of replacement pool and spa cartridge filters designed as a direct fit for Pleatco PCC60, Unicel C-7459, and Filbur FC-1940. It is engineered to fit Pentair Clean & Clear Plus 240 systems, providing 60 sq. ft. of filtration area per cartridge (240 sq. ft. total when used as a 4-cartridge set in compatible systems).

This Tier1 cartridge features a 20-micron filtration rating, capturing fine debris such as dirt, sand, body oils, leaves, and small particulates from your pool or spa water. Each cartridge offers 60 sq. ft. of reinforced polyester pleated media for high dirt-holding capacity and improved water clarity throughout the swim season.

Tier1 DPFPCC0021DTL cartridges typically last 12–18 months, depending on pool size, bather load, and water chemistry. For optimal performance, rinse the pleats every 2–4 weeks with a garden hose and chemically clean (soak in a filter cleaner solution) every 3 months. Replace the cartridges when pleats appear flattened, torn, or when pressure rises 8–10 PSI above the clean starting pressure.

Yes. Each Tier1 DPFPCC0021DTL cartridge is built with reinforced polyester pleated media, break-resistant polypropylene end caps, and a rugged inner core that resists collapse under high flow conditions. The deep-pleat design maximizes surface area while the heat-bonded construction prevents bypass, ensuring consistent filtration in Pentair Clean & Clear Plus 240 and compatible systems.

Turn off the pool pump and release pressure using the air relief valve. Remove the filter tank lid and lift out the old cartridges. Rinse the tank interior, then insert the new Tier1 DPFPCC0021DTL cartridges onto the manifold, ensuring they seat properly. Reinstall the lid, tighten the clamp, open the air relief valve, and restart the pump. Once water flows steadily from the air relief valve, close it and note the clean starting pressure for future reference.
