How does the C17502 (175 sq ft) compare to the C12002 (120 sq ft)?
Both are Star-Clear Plus single-element filters in the same narrow 13.4-inch tank with the same single locking knob design. The C17502 has 55 sq ft more filter area and a taller profile (ships 44.8 in vs. 37.7 in, requires 30 in vertical clearance vs. 25 in). It also features a glass-reinforced copolymer tank vs. standard injection-molded polymer for the C12002. Both are rated for 120 GPM. Choose the C17502 for more filter area and a more durable tank.
How often does the cartridge need cleaning?
Clean when pressure rises 8–10 PSI above the clean starting pressure. Unscrew the locking knob, remove the cartridge, and rinse with a garden hose.
