Unicel 3.5 sq ft Spa In A Box Cartridge - C-2305

Unicel 3.5 sq ft Spa In A Box Cartridge has been designed for use in pool filters. Mineral scale, rust and oils build up in most swimming spa filters and are not completely removed by backwashing, causing filtration quality to deteriorate. Keep two complete sets of spa filter cartridges on hand to eliminate down-time.
