HF-STR3-300S7-SET Premium Cartridge Replacement

Intro

The HF-STR3-300S7-SET from Hurricane Pool Filters is a complete inner and outer cartridge replacement engineered for Sta-Rite System 3 S7M120 pools and spas. This 300 sq ft kit combines a 24-inch inner cartridge with a 18-inch outer cartridge, delivering a total of 300 sq ft of filtration media. Built to tight tolerances for a seamless, plug-and-play fit, it restores peak filtration performance and water clarity.

List of Features

  • OEM-spec fit for Sta-Rite System 3 S7M120 (25021-0200S inner, 25022-0201S outer) with exact 24" inner length and 18" outer length.
  • 300 sq ft total media: 100 sq ft inner, 200 sq ft outer, delivering robust debris capture and longer run cycles.
  • Advanced point-bond media provides tighter filtration than standard trilobal or non-woven options, trapping biomass, dirt, hair, leaves and fine particulates.
  • Durable construction with reinforced pleats and end caps resists clogging, supports easy backwashing, and extends filter life between maintenance cycles.
