HEPA Air Filters: HEPA air filters, or high-efficiency particulate air filters, are a standard in most modern aircraft, but in the age of COVID-19, are particularly important because. - JRH, Reno, Nevada The HEPA (high energy particulate arrestance) filters on board commercial jets already perform that level of filtration. With apologies for the omitted word in the original post! Americans entire mainline and regional fleet features HEPA filtration. That stale, warm air you occasionally notice when a plane is on the ground sitting at the gate or idling might mean theres little circulation through those filters.

This Delta video shows a HEPA filter being replaced. This is both expensive [and much more expensive than the jetway mounted PCUs which use electricity, at that], plus of course, results in much higher carbon emissions vs electricity used to power PCUs); c.) Air quality for planes parked at the gate and using below jetway mounted PCUs can be upgraded from the garden variety G4 category used for commercial grade HVAC units to HEPA category filtration levels, but until then, the air quality during boarding and deplaning is NOT nearly as high as airlines are touting in the marketing hype.
