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) Más...Sort type: [Top] [Newest]
ISn't HEPA technology over half a century old already ? Doesn't every plane have HEPA filters?
Pretty much any pressurized airliner
Why the H does AA make it seem like they are the only carriers with a HEPA system? Donaldson APS systems have been going in 787's A320's and A330's for a while now, bleed air or not, and not just for AA. Most all aircraft have HEPA system of some sort.
Sell the sizzle! Most ppl have no idea what HEPA even stands for.
A HEPA filter is one thing and protection from Covid-19 is another. Just because HEPA *can* trap Covid-19 virii doesn't mean it will, and it doesn't mean that Covid-19 won't spread like wildfire on a plane with a good HEPA system. What is needed is a good science that measures the risks for this specific environment. That simply doesn't exist yet. This is nothing more than a misleading advert for American Airlines.
You are correct, no science here. HEPA filters are designed to filter particles of 300 nano meters or more. Not probable to have any ability to filter a virus that is 5 nano meters.
Well, not really true. First of all the virus that causes COVID19 is approximately 125 nanometers (.125 microns) not 5. Secondly, NASA quotes this study study they did (https://ntrs.nasa.gov/search.jsp?R=20170005166) that clearly shows almost 100% efficiency at .01 micron or 10 nanometers or above.
