⚠️ Own a 2025 Master Spas Hot Tub?
Heads up — if your Master Spas hot tub was made in 2025 or later, this filter won't be compatible. Master Spas recently redesigned their filtration system, and earlier filter models like this one will no longer fit the new design. Filters made for Master Spas hot tubs and swim spas before 2025 may also be from Pleatco instead of MasterClear!
Looking for the correct filters for your 2025 model? Browse our 2025 Master Spas Filter Collection to find the right fit.
