Pro Filter High Flow Cartridge (2020+ Custom Series)

This 1-pack includes one high flow pro-filter cartridge, designed for 2020 and newer Arctic Spas Custom series hot tubs that use a dual-cartridge filtration setup. The high-flow filter is to be paired with a standard or hybrid filter which gives you the particle-trapping performance of a standard filter alongside the improved water circulation of a high flow cartridge. The high flow cartridge is engineered with a more open media structure that allows greater water throughput, which can improve jet performance and reduce strain on your circulation pump. Together, this combination balances clean water with strong flow — the best of both approaches in one set. Fits: All 2020+ Arctic Spas Custom series models with pro-filter system Includes: 1 high flow pro-filter cartridge Replacement interval: Every 4–8 months depending on usage and water conditions Not sure which cartridge combination your spa runs?
