HEPA filters help passengers breathe easier

September 28, 2020 in Innovation, Technology

Did you know air in an airplane goes through similar filtration processes as those used in hospitals and industrial clean rooms?

Boeing cabins are equipped with an air filtration system that incorporates high efficiency particulate air (HEPA) filters. These have been shown to be more than 99.9% effective at removing particulates such as viruses, bacteria and fungi before air is re-circulated back to the cabin.

Cabin air is a 50/50 mix of outside air and air that passes through HEPA filters. The volume of cabin air is exchanged every two to three minutes, or more than 20 times per hour.
