Pro Filter Cartridge | Combo | 2-Pack

Replace both filters at once with this 2-pack of combo pro-filter cartridges for Arctic Spas Custom series hot tubs (2020 and newer). Combo cartridges use a multi-media design that targets a wider range of particles and contaminants than single-method filters, helping reduce chemical demand and extend time between water changes.

Swapping both cartridges at the same time ensures even filtration across your spa's system. The 2-pack also offers better value per cartridge compared to buying singles. Fits the factory pro-filter housing with no adapters needed.

Fits: All 2020+ Arctic Spas Custom series models with pro-filter system
Includes: 2 combo pro-filter cartridges
Replacement interval: Every 4–8 months depending on usage and water conditions
Save: Better value compared to buying two singles separately
