Extractor hoods with recirculation suck in the cooking vapors, filter the air with the help of a carbon filter and then lead the purified air into the kitchen. The carbon filter ensures air purification and a pleasant kitchen atmosphere. This activated carbon filter absorbs grease and moisture and prevents unpleasant odors in the kitchen. To ensure that your appliance works perfectly and the kitchen retains a fresh smell, we recommend changing the carbon filter every 3 to 4 months - depending on how often it is used and the type of food being prepared (fried, fatty food, steam, etc.).
