Carbon filter set – for odours and VOC reduction
The carbon filter set for Systemair SAVE VTR 250/B contains activated carbon, which helps to reduce:

- volatile organic compounds (VOCs)
This set is especially recommended for homes in high‑traffic areas, near industrial zones or where odour control is important.
How often should SAVE VTR 250/B filters be replaced?
Recommended replacement interval for Systemair SAVE VTR 250/B:
- 1–2 times per year in standard residential use
- more frequently if:
- you live in a high‑traffic or industrial area
- there are construction works nearby
- there is a lot of dust or pets in the home
Filters should be replaced earlier if they are visibly dirty or if the unit indicates a filter/maintenance alarm. A clogged filter increases pressure drop, reduces airflow and raises energy consumption.
Filter installation in Systemair SAVE VTR 250/B
When replacing filters:
- switch off the unit before opening the service door
- remove the old filters carefully to avoid dust spreading inside the unit
- check the airflow direction arrows on the filters and install them accordingly
