permalyt® recirculation filter

A self-cleaning recirculation filter

The berbel permalyt® recirculation filter is maintenance free: It is the first recirculation filter system to regenerate itself! A thermal catalysis process makes this possible. With berbel, clean air in your kitchen is child's play.

Lasting odour trapping - maintenance free

The filter mats consist of a special active carbon block - unique in kitchen technology as yet. This binds up to 97% of the odour molecules that arise during cooking. They are neutralised with the help of a catalyst (thermal catalysis process). The one-off installation of the innovative filter ensures lasting function - without even having to change the active carbon.

More details on the features


1. Normal mode:
During normal operation, air flows through the filter mats, which capture the odorous substances. The odour elimination rate is 97%.

2. Thermal catalysis:
During the regeneration phase, the heating cartridge in the catalyst heats the core to around 140°C.

Once the target temperature is reached, the circulation fan starts. The hot air flowing from the catalyst heats up the inside of the filter to around 50°C.

This temperature ensures that any embedded odour molecules are released from the active carbon mats and then flow through the catalyst. Here, they are broken down and converted into CO2 and oxygen.

After a total time of around 120 minutes, all of the odour molecules have been broken down and the filter is regenerated. The regeneration process can be interrupted at any time by switching on the hood.
