High-Capacity Cartridge Filtration for Clear, Consistent Pool Water

For pool owners who want powerful filtration without the mess and complexity of backwashing, the Pentair Clean & Clear Plus 420 Cartridge Filter delivers proven performance. This complete cartridge filter system provides 420 square feet of filtration area, making it ideal for large residential inground pools that demand strong flow rates, excellent water clarity, and reduced maintenance.

Designed for durability and efficiency, the Clean & Clear Plus 420 is a go-to choice for homeowners and service professionals looking for long filter cycles and dependable operation.

Large Filtration Area Means Fewer Cleanings

With 420 sq. ft. of total cartridge surface area, this system captures fine debris while maintaining low system pressure. The increased surface area allows dirt to spread evenly across the cartridges instead of clogging quickly, which extends time between cleanings and improves overall circulation efficiency.

Cartridge filtration also eliminates the need for backwashing, saving water and helping maintain stable pool chemistry.

Why a High-Capacity Cartridge Filter Matters

Undersized filters lead to cloudy water, frequent cleanings, and added strain on pumps.

Why it matters:

• Provides superior water clarity

• Reduces filter cleaning frequency

• Maintains lower operating pressure

• Saves water compared to sand and DE filters

Durable Pentair Construction Built for Long-Term Use

The Clean & Clear Plus 420 features a reinforced fiberglass tank designed to withstand high pressure and harsh pool environments. Internal components are engineered for balanced flow and easy service access, making routine maintenance straightforward for both homeowners and technicians.

Pentair’s locking clamp system allows quick, secure access to the cartridges without complicated disassembly.

Ideal for Large Residential Inground Pools

This filter system is well suited for:

• Large residential inground pools

• Pools with high bather loads

• Pools paired with variable-speed pumps

• Owners seeking low-maintenance filtration

The Clean & Clear Plus 420 integrates easily into most standard pool plumbing configurations.

Maintenance & Service Notes

Cartridges should be removed and cleaned periodically based on pressure rise and debris load. Cleaning typically involves rinsing with a hose and, when needed, soaking with a cartridge cleaner. Proper cartridge care extends filter life and maintains peak filtration performance.

Replacement cartridge sets are readily available and should be replaced when fabric shows signs of wear or reduced effectiveness.
