Filter installation
Before replacing the filters, it is recommended to read the unit’s user manual. During installation you must follow the direction of the airflow – the arrows printed on the filter must point towards the rotor (heat exchanger).
Make sure that the filter frame sits straight and seals well, without gaps around the edges where air can bypass the filter.

- more frequently if:
- you live in a high‑traffic or polluted area
- there are construction works nearby
