Shop Pentair Cartridge, Sand & D.E. Filters

Pentair manufactures several well-known filtration families, including Clean & Clear, Clean & Clear Plus, Clean & Clear RP, FNS Plus, Triton, Triton II, Tagelus, Sand Dollar, and FullFloXF. Each filtration type has different maintenance requirements, flow characteristics, and installation considerations.

Pentair Cartridge Filters

Cartridge filters are popular because they do not require backwashing and can offer a large filtration area in a relatively compact footprint. Pentair Clean & Clear and Clean & Clear Plus models are available in multiple square-foot sizes, including popular 100, 150, 320, 420, and 520 sq. ft. configurations. Larger cartridge area can help extend the time between cleanings when the system is properly sized.

Pentair Sand Filters

Pentair Triton, Triton II, Tagelus, and Sand Dollar filters are common choices for customers who prefer traditional sand filtration and backwashing. When replacing a sand filter, confirm tank diameter, sand capacity, plumbing size, valve configuration, and available equipment-pad space.

Pentair D.E. Filters

Pentair FNS Plus D.E. filters provide fine filtration and are available in multiple square-foot ratings. D.E. systems require additional maintenance compared with cartridge filters, including grid inspection and proper recharging after cleaning or backwashing.

How to Choose the Right Pentair Pool Filter

Filter selection should be based on more than pool gallons alone. Important factors include pump flow, plumbing size, turnover requirements, debris load, maintenance preferences, equipment-pad space, and whether the pool includes a spa or high-flow features. The filter should never be undersized relative to the pump and plumbing system.

If you are upgrading to a larger variable-speed pump, it is especially important to confirm the filter's maximum flow rating and plumbing limitations.

Pentair Filter Replacement Help

Replacing an older filter can involve more than matching tank diameter. Send us the existing filter model, square footage, pump model, plumbing size, valve information, and clear equipment-pad photos. We can help identify current Pentair replacement options and point out important size or plumbing differences.

Pentair Filter Parts & Compatibility

Many Pentair filters use model-specific cartridges, grids, manifolds, air-relief assemblies, clamps, drain plugs, and internal plumbing components. Always verify the complete filter model and square-foot rating before ordering replacement parts.
