According to the Centers for Disease Control and Prevention (CDC), HEPA filters capture 99.9% of particulate matter from the air, including fungi, bacteria and viruses, from 0.1 a€“ 0.3 micrometers in diameter. 1 2 HEPA stands for High Efficiency Particulate Air and is a common type of filter used on planes. What HEPA filters do, essentially, is to remove any impurities in the air, no matter how small. A New York Times report and this NASA study show that this includes tiny COVID-19 microns. 3 4 Thanks to HEPA filters and efficient circulation on commercial aircrafts, the air you breathe in flight—though not necessarily entirely virus-free—is much cleaner than the air in restaurants. 5 The air conditioning and pressurization system works in combination with the HEPA filters to recirculate the air every two to three minutes by providing 50% HEPA filtered recirculated air mixed with 50% outside air. It removes 99.97% of particles – including viruses and bacteria - during both ground and air operations. 6 HEPA filters are a very high-intensity system of fibers that you essentially run air through to filter out an incredible amount of contaminants — not just dust, not just bacteria, but moisture, any sort of contamination that could potentially harm or create an atmosphere in the cabin or the cockpit that could harm the passengers or the crews. 7 8 Alla vara flygplan fran Airbus och Boeing ar utrustade med HEPA-filter. 9 Moderna passagerarflygplan ar utrustade med sa kallade HEPA-filter, som ocksa anvands for att rengora luften vid sjukhus operationssalar. 10 12
