Coarse Filters

The supply and exhaust air coarse filter fabrics typically become dirty more quickly than the fine filter cassette in the supply air. By ordering extra coarse filters, you can replace only the dirty supply and exhaust filter fabrics without needing to replace the fine filter cassette.

Made in Finland

We have selected a domestic manufacturer for our replacement filters, whose high-quality Finnish materials, structure, and properties closely match those used in the original factory filters. Our goal is to offer solutions for healthy indoor air, low pressure drop, long service life, and low energy consumption.

FILTER REPLACEMENT

Remember to replace the filters often enough. Clogged filters do not function as intended.

The recommended replacement interval for filters is 2–3 times per year. A good rule of thumb is to replace the ventilation unit's filters in the spring and autumn.

Also clean any loose dirt from the ventilation unit, for example by vacuuming. Check the cleanliness of the heat recovery unit as well, and clean it with a suitable coil cleaner if needed.

GOOD INDOOR AIR QUALITY

High-quality indoor air is dust-free, odorless, draft-free, and tasteless—it feels almost like "nothing." However, its positive effects are felt, whether consciously or subconsciously.

In contrast, poor indoor air quality is quickly recognized by the problems it causes.

Filters are one of the most important components of a ventilation system and have a significant impact on indoor air quality. That’s why it’s worth investing in regular filter changes and in high-quality filters—to minimize harmful pollutants and particles from outdoor air and to improve the overall healthiness of indoor air.
