Filters that Ensure Fresh, Clean Fun

High-Performing, Long Lasting Filtration Media for Pools & Spas

Keep your pools, spas, and hot tubs clean and comfortable with Porex filters. These rigid, lightweight filters maximize surface area and flow rates and have excellent chemical and physical resistance while cleaning to ensure a long serviceable life. Radial, tube, and sheet filters are easy to install into new and existing pool and spa filtration systems, provide a high flow capacity, and have high solids loading to eliminate debris. All of our filtration media is customizable to meet individual water filtration system requirements.

Swimming pool filters from Porex can be used with sand filters or customized to meet your filtration system needs.  To extend the life of the filter, these porous filters are back-washable, cleanable, reusable and facilitate flow to ensure optimal filtration efficiency.

Porex’s radial cartridge filters are unique, porous plastic cartridges designed to fit standard cartridge filter housings in spas and hot tubs. The single-layer, one-piece molded polyethylene (HDPE) cartridges are back-washable and cleanable.
