The 420 SqFt Pentair Clean & Clear Plus Cartridge Filter offers superior filtration with a range of features designed for durability, efficiency, and ease of maintenance.

The filter tank is made from corrosion-resistant, injection-molded, fiberglass-reinforced polypropylene, providing exceptional strength and reliability. This construction ensures long-term performance, even in harsh pool environments. In addition, the filter assembly uses four non-woven, polyester cartridges, which offer excellent dirt-holding capacity while eliminating the need for backwashing, thus saving both water and time on maintenance.

Key Features:

• Large filter area increases dirt-holding capacity, allowing for longer filtration cycles without frequent cleaning or cartridge replacement. As a result, you can enjoy extended performance with fewer interruptions.
• 100% drain clean-out port makes it easy to fully drain the system, enabling a quick and thorough cleaning process. This ensures optimal performance and extends the life of the filter.
• Continuous High Flow™ Internal Air Relief works by preventing air pockets from disrupting the filtration process, thus maintaining smooth water flow and enhancing system efficiency. Consequently, the filter operates more effectively with consistent pressure.
• Durable injection-molded tank resists corrosion and wear, ensuring long-lasting performance. This feature guarantees better durability and reliability, even in demanding pool conditions.
• Balanced hydraulic flow optimizes the system’s performance by preventing pressure loss, which ultimately ensures consistent, effective filtration.

Overall, with these advanced features, the Clean & Clear Plus filters provide high performance, reduced maintenance, and exceptional reliability. Therefore, they make an excellent choice for both residential and commercial pools looking for efficient, low-maintenance filtration solutions.
