Product Overview

The Pentair Clean & Clear Plus 520 sq ft (EC-160332) is a high-capacity, four-cartridge filtration system engineered for large residential pools. With approximately 520 sq ft of total filtration area, it provides exceptional debris-holding capacity, extended cleaning intervals, and superior water clarity. Its rugged injection-molded, fiberglass-reinforced tank is built to resist corrosion and heavy usage, while the tool-free removal of cartridges keeps maintenance fast and simple.

Ideal For

• Pool owners with larger inground pools who need extended cartridge service intervals.

• Installations upgrading from smaller filters to handle heavy swimmer usage, oak pollen zones, or fine debris loads.

• Users looking to minimise maintenance and water usage by switching to a no-backwash cartridge system.

• Service professionals who want a robust, low-maintenance filter that supports high-performance pumps.

Customer-Facing Q&A

Q: How often do I need to clean the cartridges?
A: Cleaning frequency depends on pool use, debris load, and pump flow, but the large-capacity design significantly extends time between cleanings compared to smaller filters.

Q: Does this filter require backwashing?
A: No. This cartridge system does not require backwashing. Simply remove, rinse, and reinstall the cartridges for fast, effective maintenance.

Q: Is it suitable for saltwater pools?
A: Yes. The corrosion-resistant materials and solid construction are fully compatible with salt chlorination systems.

Q: Which pump should I pair it with?
A: It pairs best with variable-speed or two-speed pumps sized appropriately for your pool volume and plumbing layout, ensuring balanced flow and efficient filtration.

Q: What are the benefits over a smaller filter or sand/DE system?
A: The Clean & Clear Plus 520 provides greater cartridge surface area (thereby higher flow and clarity), quicker maintenance (no backwashing), and reduced water waste—ideal for high-demand environments.
