Finnair works toward fleet-wide fitment of HEPA filters

0

Finnair is installing HEPA (high-efficiency particulate air) filters on the recirculation systems of its entire ATR 72 turboprop fleet in a project running between June 2021 and early 2022. The Finnish airline has already fitted its Airbus and Embraer fleets with HEPA filters, which remove dust, allergens, bacteria, viruses and other potentially harmful particles from the cabin air, with an efficiency of 99.97%.

Finnair’s fleet of 12 ATR aircraft is operated by partner airline, Norra, on short-haul domestic and regional routes. Fresh air will be supplied from the overhead stowage compartment level and extracted at floor level, creating vertical airflow, rather than a lateral flow along the cabin. The HEPA system changes the cabin air every three minutes.
