This Purezone 400 replacement filter is designed for Vortex, O2, and Arcadia spas using threaded filter systems. It may also be compatible with other spa brands or models.
Superior Micro-Filtration:
While standard filters trap particles as small as 50 microns (50/1000th of a millimetre), Purezone micro-filtration captures particles down to 5 microns (5/1000th of a millimetre)—delivering noticeably cleaner spa water.
Compatibility Tip:
- Does your Vortex or O2 spa have three filters? If yes, this is the correct Purezone filter for your system.
- Check the filter face image in the additional views to confirm compatibility.
Color Note:
Filter color may vary (blue or brown). This does not affect performance.
Filter Configuration:
Each spa uses:
1 x Purezone filter
2 x Pleated cartridge filters
(Alternatively, 3 x pleated filters may be used.)
