At colder temperatures, a minimal opening of just a few millimeters ensures sufficient and draft-free ventilation. The minimum opening can be adjusted according to installation conditions. The vent can also be manually closed if needed. The filter, made from 3M Filtrete™ material, has unique efficiency based on an electrical charge that actively attracts airborne contaminants like a magnet. According to VTT research, the filter removes 100% of pollen and significantly reduces harmful fine particles affecting health. The vent is easy to install. The telescoping pipes included in the package (each approximately 150 mm long) partially slide into each other and can be easily shortened if needed.
