Pro Filter Cartridges | Standard & High Flow | 2-Pack

This 2-pack includes one standard and 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 pairing 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 standard + 1 high flow pro-filter cartridge (verify this is accurate — adjust if both are the same type)
Replacement interval: Every 4–8 months depending on usage and water conditions
