Keep your pool water crystal clear and ready for anything summer throws your way with the Clarus® CPF-1226 Replacement Filter Cartridge. Built to capture the gunk that clogs flow and clouds water such as dirt, sand, leaves, hair, oils, pollen, and other fine debris, before it messes with your circulation (and your swim time). This filter delivers serious cleaning power with washable, reusable performance that keeps your pool sparkling and swim-ready. Because murky pool water just isn’t an option.

• Big Capacity, Bigger Results: ProGrade™ pleated media captures everything from fine sand and dust to leaves and body oils, keeping water balanced, clean, and swim-ready.
• Built-In Defense: Treated with antimicrobial protection to help inhibit bacteria, mold, and mildew growth on the filter media, so it stays fresher between cleanings.
• Stronger Flow, Less Stress: DiamondCore™ Technology improves circulation and prevents clogging to protect your pump and extend equipment life.
• Rinse, Reuse, Repeat: Rinse when filter pressure rises 8–10 PSI above your clean baseline, about every 6–8 weeks during regular pool use (check every 5–6 weeks during peak season, heavy debris, or high bather load). Replace when pleats become frayed, bands snap, end caps are damaged, cleanings become more frequent, or if flow/pressure won’t recover after proper cleaning. With proper care and balanced water, filters typically last 3–5 pool seasons.
• Made to Last (Like Your Summer): Reinforced end caps and pleats resist pressure, backflow, and wear—even after repeated cleanings.
• Protect What Powers Your Pool: Shields your pump and filtration system from debris that causes strain, ensuring smoother performance all season long.
• Peace of Mind: Certified to NSF/ANSI 50 standards for safe, high-performance filtration that keeps your water clear and your swim days uninterrupted.

Note: This listing includes 1 cartridge, but is designed for 4-cartridge housing systems. Each cartridge delivers 106 Sq. Ft. of filtration for a total of 424 Sq. Ft. of filtration capacity. It’s recommended to clean and replace all 4 filters at the same time for even filter wear and performance.

Clarus® filters are made for clarity, built for better pool days.
