Description

The Pentair Clean & Clear Plus Cartridge Filter 320 (SKU EC-160340) delivers high-capacity performance for residential swimming pools where clarity and ease of maintenance are key. With 320 square feet of media, the filter traps more debris and extends the time between cleanings. Its tank, made from fiberglass-reinforced polypropylene, is built for long life in harsh pool environments. The four coreless cartridges simplify maintenance—just remove, rinse, and reinstall. Supporting flow up to ~120 GPM, this filter keeps pace with higher-capacity systems. The full drain port and built-in air relief streamline seasonal servicing and maintenance chores. For pool owners who want premium filtration without constant upkeep, this model ticks the boxes.

Pro Tip

Keep your pump flow ideally under ~120 GPM and allow sufficient vertical clearance above the filter for cartridge access (12-16″ is a good guideline). When your pressure gauge climbs ~10 psi above its starting level, remove and rinse the cartridges. While servicing, check the clamp ring and O-ring for wear to ensure a reliable seal.
