| Manufacturer: Sta-Rite

From $349.00 to $588.00

Posi-Flo® II Filters remove particles so small you can't even see them. And, that includes gel-like particles from suntan and body oils, as well as sand, dirt and leaves. What's more, the filter element in Posi-Flo® II Filters holds more dirt than others of the same size. The secret is a balanced-flow hydraulic design that directs water equally over the entire surface area of the element, for greater dirt holding capacity before needing cleaning.

  • Typical Installations – Inground pools and inground hot tubs
