摘要

The application relates according to one embodiment to an air filter (104) for grease filtering. The filter comprises a filter mounting element (112) for installing the filter in connection with an intake opening (102) of an air ventilation duct (101), at least one mechanical separation element (120) for separating solid impurities from flowing air (103), and a UV source mounting element (132) capable of being fitted with a UV source (130) for generating UV light. The UV light and a catalyst coating present inside the filter are adapted to transform the physical state of grease flowing into the ventilation duct along with the airflow.
