Demineralization Cartridge AOS 7531

System and Use

All AIR-O-SWISS ultrasonic humidifiers are equipped with a powerful and exchangeable demineralization cartridge to ensure water mist without lime scale or mineral residues.
The cartridge has a silver treated plastic housing with Ag⁺ Ionic Silver Technology. That inhibits microbial growth on the surface of the cartridge.
Cartridge is refillable – 3-Pack refill granules available (AOS 7533)
Easy replacement
Odorless granules used
The demineralization cartridge needs to be replaced every 2 – 3 months depending on the water hardness. If the water is very hard (= high amount of minerals), it may be necessary to replace the cartridge after 1 – 2 months.
In case distilled or reverse-osmosis water is used with the ultrasonic humidifier, the use of the demineralization cartridge is not necessary.

AOS 7531 is an accessory for all these:

AOS 7131, AOS 7133, AOS 7135, AOS 7142
