What do the exhaust air filters do?

The exhaust air filters regulate exhaust air flow to ensure that it is discharged evenly into the ambient air and also protect the interior of the device against dirt. Whilst these filters do not have an active filtering function, the backward flowing ambient air can soil them very easily.

We recommend changing them every 1-2 years.

If the exhaust air flow in the room is of secondary importance (e.g. in large halls without permanent work stations close by), it is also possible to opt for terminal metal filters for the exhaust air, which do not need to be replaced at all.
