Clean air system - Zeolite filter cleans itself using active oxygen Zeolite filter cleans itself using active oxygen
The active oxygen, which is generated by the Corona particle charger, passes through the zeolite filter, where it oxidizes the trapped gases and renders them harmless. This process ensures the zeolite filter is constantly rejuvenated, extending its working life over many years.

Long-lasting performance of up to 5 years
The 6-stage CleanAir system offers a long-lasting performance of up to 5 years. Thanks to its uniquely open structure, the 3-stage ElectroClean particle filter has a continuously high flow-rate. This means it can catch particles efficiently for longer without clogging up. The 2-stage zeolite filter traps gases and odours, which are subsequently oxidized by the active oxygen passing through, constantly rejuvenating the zeolite filter.

Unique technology for high-humidity conditions (>90%)
The 2-stage zeolite filter is made of advanced hi-grade zeolite, which, unlike many other materials, efficiently captures gases and odours without also capturing water molecules. This means it continues to remove gases and odours even under very humid conditions of up to 90% humidity.
