Description

• Maintain peak filtration performance for your multi-cartridge pool system with Fil-Fresh professional-grade replacement cartridges. Engineered for Hayward SwimClear C3030/C3025/C3020, Star-Clear C580E and equivalent high-flow filtration systems, this 4-pack delivers commercial-quality debris capture and extended service intervals.
• Advanced Filtration Technology:
• Trilobal pleated media architecture maximizes surface area for superior particulate retention, capturing fine debris that standard filters miss. The unique three-lobe structure promotes even debris distribution, preventing channeling and maintaining consistent flow rates throughout the cleaning cycle. 324 sq.ft total filtration area across four cartridges ensures comprehensive system coverage.
• Critical Sizing Note:
• Measure your existing cartridge before purchase: 19-3/4" length x 7" outer diameter x 3" inner diameter. Do not rely on pool size or cleaner brand alone for compatibility verification. Incorrect sizing will result in installation failure or system bypass.

FAQ Section

• Q: How do I verify this fits my filter system?
• A: Measure your existing cartridge: 19-3/4" length, 7" outer diameter, 3" inner diameter (open both ends). This cartridge fits Hayward SwimClear C3030, C3025, C3020 and Star-Clear C580E systems. Cross-references: CX580XRE, Pleatco PA81/PA81-4, Unicel C-7483/C-7483-4.
• Q: How do I clean my C3030 filter cartridges?
• A: Remove cartridges from filter tank and rinse trilobal pleats thoroughly with garden hose from top to bottom. Rotate cartridge while cleaning to ensure all pleat surfaces are flushed. Allow to dry before reinstallation. Monthly cleaning recommended during high-use season.
• Q: How often should I replace these cartridges?
• A: With proper monthly cleaning, typical lifespan is 1-2 pool seasons. Replace when pleats remain stained after cleaning, fabric shows structural wear, or when system pressure indicates reduced flow despite clean cartridges.
• Q: What is the advantage of trilobal media structure?
• A: The three-lobe pleat design increases surface area while promoting even debris loading. This prevents premature clogging at single points and supports more efficient cleaning when rinsed.
• Q: Why is this a 4-pack?
• A: The Hayward SwimClear C3030 system uses four cartridges simultaneously. This package provides complete filter system replacement. C3025 uses three cartridges; C3020 uses two—purchase accordingly for your specific model.
