Why Our Filters Last Longer

End Cap
Made with anti-microbial, crack resistant polyurethane, that inhibits growth of bacteria, and is resistant to chlorine and bromine.

Core
Designed to maximize flow for improved efficiency, while reduces wear and tear on the pump, and extends cartridge life.

Band
Tightly secured to each pleat to prevent pleat from folding over, and maximize usable filter area. Many filters have none.

Fabric
Made of the highest grade spun bonded filtration fabric. More resistant to rot and mildew, easy to clean, and designed to retain physical shape even when exposed to solvents so that it will withstand more frequent cleaning cycles.
