Breathing Clean Air At 30,000 Feet On American Airlines, Thanks To HEPA Filters
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. (news.flightag.com) Mais...Sort type: [Top] [Newest]
Nice, but how often are the filters cleaned or replaced. Does HEPA remove SARS-CoV-2 virus as well?
Ventilation systems would be best if fitted with ultra violet light
Unfortunately using industrial UV-B in an aircraft air system would produce too much ozone. If they could get UV-C to kill "nasties" at a faster rate, then it would not be so bad.
This would be similar to those which will eventually be installed in all public buildings.
Anyway, it's time for the people in the white lab coats to get cracking

Those would be UV-B..the reason being is the air is recirculated more at a faster rate, along with huge amts of fresh air intake. Ozone levels would be very very low.
Most, if not all, household air cleaners that use a UV light, use UV-C but it is because the air is not circulated as fast, and so the light can do it's job. All about the lights wavelength.
You are right thou, time for researchers to discover better air cleaning methods besides just using HEPA, for aircraft.

I call BS marketing that offers minimal virus protection, This is keeping mosquitoes out with a chain link fence. HEPA filters must remove: 99.97% of particles that have a size greater than or equal to 0.3 µm. Problem is corona virus is 5 nm which is 0.005 µm or 60 times less than the holes in the filter,
