This cartridge is a direct-fit replacement for Pentair Clean & Clear and Clean & Clear/Predator cartridge filters used on aboveground pools and spas. Built to the original equipment dimensions, the R173215 provides the surface area and pleat configuration needed to capture debris, reduce filter runs, and keep pump strain down. The cartridge measures 10 inches long, 10 inches wide, and 23-31/50 inches tall, matching manufacturer specs for a quick swap without modification.

How will this cartridge affect my pool's filtration performance?

Installing a new R173215 brings the filter back to manufacturer-intended efficiency, improving particle capture and maintaining proper flow rates. Fresh pleats mean more available media area for contaminants, so the filtration cycle runs as designed and your pump works less hard to move water.

• 100 square feet of pleated media increases contaminant capture.
• Original equipment sizing ensures consistent flow and pressure.
• Restores cleaning intervals to the filter's normal schedule.

Is this cartridge easy to install and compatible with my system?

Yes—this replacement element is manufactured to fit Pentair Clean & Clear and Clean & Clear/Predator aboveground pool and spa filters without adapters. The matching dimensions and standard end-cap design let you remove the old cartridge and seat the new one quickly, with no special tools required.

• Designed for direct-swapping into compatible Pentair housings.
• Standard end-cap profile aligns with factory filter mounts.
• Installation typically takes only a few minutes for routine maintenance.

What maintenance steps keep the cartridge working longer?

Regular rinsing and periodic deep cleaning prolong the life of the cartridge. Rinse with a garden hose at a moderate angle between uses; for thorough cleaning, soak the cartridge in a filter-cleaning solution according to product directions and let it fully dry before reinstallation.

• Rinse debris off after each filtration cycle.
• Deep clean with an enzymatic or alkaline filter cleaner seasonally.
• Inspect pleats and end caps for cracks; replace if damaged.

Will this cartridge fit aboveground pools and spa setups of various sizes?

The R173215 is intended for aboveground pool and spa filter housings that accept Pentair Clean & Clear cartridges. While it restores filtration performance, confirm housing model compatibility and clearance before purchasing to ensure proper fit and circulation.

• Fits Pentair Clean & Clear and Clean & Clear/Predator cartridge filters.
• Check housing model and available interior length for fit confirmation.
• Use with compatible pump and plumbing for balanced system operation.

Who is this for: pool and spa owners who use Pentair Clean & Clear or Clean & Clear/Predator cartridge filters and need a reliable, OEM-dimension replacement. Ideal for those looking to restore original filtration performance without modifying their system—especially seasonal maintainers, aboveground pool owners, and spa operators seeking predictable flow and easier upkeep.
