Breathing clean air at 30,000 feet on American Airlines, thanks to HEPA filters. American has been using these filters to purify the air on their entire mainline and most regional fleet since the late 1990s. The HEPA technology is also used help keep medical environments clear of bacteria and viruses while providing clean air.

While the cabin air circulates every 2 to 4 minutes, the HEPA filters capture at least 99.97% of airborne microbes providing a comfortable experience for passengers.

“Over the past several years, American has been further improving our HEPA filters by adding a layer of activated carbon to our filters to provide additional removal of fumes, odors and volatile organic compounds,” said Ben Thiesse, American’s Senior Engineer for the Airbus A320 Family. “Today, these carbon HEPA filters are installed on all of American’s A320 and 787 aircraft.”
