- NEW and patented refill process!
- When properly installed and maintained the granules effectively help to prevent the release of minerals in the air.
- Granules should be replaced every 2 – 3 months; hard water usage may require more frequent replacement.
- One box includes 3 single refill packets - use just one packet per refill.
- For use with the AIR-O-SWISS demineralization cartridge AOS 7531.
AIR-O-SWISS offers two options for replacing the demineralization cartridge: Replace the whole cartridge with a new part (model AOS 7531) or use replacement granules (model AOS 7533 Refill Granules 3-Pack) to extend the life of the cartridge.
