[–] FunkyMonkey@feddit.de 15 points 3 years ago* (last edited 3 years ago) (1 child) The majority of airplanes are equipped with HEPA filters. As in, removing 99,97% of particles over 0.3 micron in size. The unfiltered air is fed in from the outside. It's pretty clean and not a consideration for allergens like peanut particles.

HEPA filters remove 99.97% of particles that are 0.3 micron in size. (That is the size of particles they're tested with, as it's the most difficult to filter.) They remove over 99.97% of particles larger or smaller than 0.3 microns. permalink fedilink source parent
