Extra coarse filter

Coarse filter mats for supply and extract air often become dirty faster than the fine filter cassette for supply air. By ordering extra coarse filters, you can replace only the coarse filter mats for supply and extract air without replacing the fine filter cassette if necessary.

FILTER REPLACEMENT

Remember to change the filter often enough. Clogged filters will not work as intended.

• The recommended filter replacement interval is 2 times per year. A good rule of thumb is to change the filter in your ventilation unit at least in the spring and autumn.
• Also remove any loose debris from the ventilation unit, e.g. by vacuuming.
• Also check that the heat recovery cell is clean and wash it if necessary with a suitable cell cleaner.

GOOD INDOOR AIR

When indoor air is of good quality, it is dust-free, odor-free, draft-free and tasteless! It is somehow “non-existent”. But everyone, consciously or unconsciously, feels its positive effects within themselves.

In contrast to good indoor air, poor indoor air and related problems are identified very quickly.

Filters are one of the most important components in ventilation systems and have a significant impact on indoor air quality. It is therefore worth investing in replacement and quality filters to minimize harmful air pollutants and particles from outdoor air and thereby improve the health effects of indoor air.
