- Generally, change the internal and external filters together.
- Only use original air filters with the prescribed filter class. Otherwise there is a danger to health from harmful substances that can accumulate in the air filter.
- Change the air filters regularly, after 6 months at the latest.
- Replace the air filters even after the ventilation unit has not been used for a longer period of time.
