The Pentair 420 Cartridge Filter (part of Pentair’s Clean & Clear line) and is built for high-capacity, low-maintenance performance in medium to large pools. Here’s what you need to know if you’re trying to figure out if you should consider it for your setup.
What swimming pools work best with the Pentair 420?
The Pentair 420 Cartridge Filter is best suited for medium to large pools and high-flow systems, as well as for setups with water features. It’s built to handle up to 150 gallons of water per minute using standard 2-inch pool pipes, so it’s a good choice if your pool needs powerful and consistent circulation.
Sharing the workload inside the tank are four cartridges, which spread out the water flow and debris load while helping each cartridge last longer and maintain steady filtration. With a fiberglass-reinforced polypropylene tank, the filter ensures that you don’t have to worry about corrosion and wear and tear, even if you use your pool frequently.
How does the Pentair 420 Cartridge Filter keep your pool cleaner with less effort?
- Quick draining for easy maintenance: The oversized drain port lets you flush out water fast when it’s time to clean the filter. With proper use, the cartridges typically only need cleaning every few weeks — much less often than smaller filters.
- Built-in air relief: An internal air bleed system automatically releases trapped air, so you don’t have to manually vent it or deal with performance dips.
- Durable design: The one-piece, fiberglass-reinforced tank and base hold up against pressure and outdoor wear for many, many years.
With these features, you’ll spend less time on maintenance while keeping your pool water cleaner and your system running smoothly!
