Description

The Pentair Clean & Clear Plus Cartridge Filter 520 (SKU EC-160332) is built for high-demand residential pool systems where clarity, flow, and durability matter. With 520 sq ft of cartridge media and a flow capability up to 150 GPM, this filter supports large water volumes while reducing service intervals. The robust one-piece tank withstands pool chemicals and outdoor exposure, while the four coreless cartridges enable efficient rinse-only maintenance. With high-flow plumbing and full-drain access, it represents a performance-driven, low-maintenance filtration solution for serious pools.

Pro Tip

Ensure your pump flow remains under the ~150 GPM rating to protect media life and water clarity. Leave adequate vertical clearance above the filter lid for cartridge removal. When system pressure rises ~10 psi over clean start, hose off cartridges. Replace cartridges every 3-5 years, depending on conditions.
