- Micron rating
- 5
This two-cartridge set combines a coconut shell carbon block filter with a spun polypropylene sediment filter for standard 20" x 4.5" Big Blue / Full Flow housings. The carbon stage helps reduce chlorine taste and odor, while the sediment stage retains sand, dirt, silt and rust particles.
Both cartridges are individually wrapped and fit standard 20" Big Blue housings.
