This inner filter is for Master Spas manufactured 2004 and later. It is used with an outer filter. Click Here to see the outer filter used with this cartridge.

NOTE:This filter does not have minerals embedded in the filter media. Many of our customers use this filter as a direct replacement for their original inner filter. If you prefer the mineral effect we recommend that you use this filter in conjunction with a SpaRX mineral cartridge, which lasts 4-6 months and is a very cost-effective solution.

If your inner filter has a `screw-in` bottom, we recommend that you use our One Piece Replacement which replaces both filters with a single filter.
