Keep your pool water crystal clear and ready for anything summer throws your way with the Clarus® CPF-3753 Replacement Filter Cartridge Set. 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 cuts into your swim time. These washable, reusable cartridges deliver serious cleaning power to help keep your pool sparkling, clear, and swim-ready all season long. With this 2-pack, a fresh replacement filter is available for your next changeout. 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 every 1–2 weeks during regular pool use. Replace when pleats become frayed, bands snap, end caps are damaged, or if flow/pressure won’t recover after proper cleaning. With proper care and balanced water, filters typically last 2–4 weeks.
• 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, efficient filtration that keeps your water clear and your swim days uninterrupted.
