Finnair is installing high-efficiency particulate absorbing (HEPA) filters on the recirculation system of its entire ATR turboprop fleet. The HEPA air filtration system is the most effective technology for cleansing and purifying aircraft compartments’ air. The particulate filtration removes dust, allergens, bacteria, viruses, and other irritating particles from the cabin’s air with an efficiency of 99.97%. Finnair’s Airbus and Embraer aircraft are already fitted with HEPA filters, and now HEPA filters are also being installed on its ATR aircraft.

Finnair’s ATR fleet currently consists of twelve aircraft, operated by Finnair’s partner company Norra on short-haul routes in domestic and regional traffic. The installations of the HEPA filters in the ATR fleet will begin in June and be completed by early 2022.
