Alternative Option Available: You can also use the Vortex® Spas Cam Lock Filter (SKU: 125979) as an alternative to this product.
Please Note: To use this alternative filter, you must install the Vortex® Spas Cam Lock Adapter (SKU: 200093). This adapter is a one-time purchase only; once installed, you can simply swap out the Cam Lock filters in the future.
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.)
