Corona Virus #6

[RSR]

Airliner cabin air these days is recirculated plus fresh and HEPA filtered which is a significant step up from N95 filtration. It’s way purer than what you breathe in any building short of a modern hospital or clean room high tech manufacturing.

Pretty sure heat for the cabin comes from waste heat from the engines just like in a car. No extra fuel needed.

See the earlier discussion/explanation about filters in general and efficacy of them. HEPA filter are N100 filters. They still only filter particles greater that 0.3 microns in size, they just do it more effectively.

The SARS-CoV-2 virus and the droplets that it is encapsulated in from breathing/speaking/coughing are much smaller than 0.3 microns.

So, you can bet if someone is sick on an airplane, those droplets are floating around free for all to breathe in. HEPA filters won't do much at all to take them out of the air.

HEPA filters have a range that filters coronavirus. Stop trying to promote fear.

From what I have read, HEPA filter are N100. There may be different kinds, and if so, they may be more effective. If you are aware, please point me to an article discussing the particles sizes that are filtered by airplane HEPA filters. Everything I have found says they are N100.

If they are N100, that means they filter 99.97% of particles greater than 0.3 microns. The Coronavirus is significantly smaller than that. They won't work to filter it out of the air.

It's not fear, it's science. If you'd like, I'd be happy to point you to the peer-reviewed scientific papers that discuss these issues.

Cut to reality. Give links to all the coronavirus outbreaks attributable to aircraft HEPA filters ....

Yes, but you dont catch heart disease at the corner store, or from talking to someone...

For fun today, I built a "sterilizer" box to sit the mail in for an hour or two after it comes out of the mailbox. Used a UV-C light that is normally used in metal duct work to help sterilizer air flow, mounted in the top of a box I knocked together out of scrap wood. Lined the inside with aluminum foil to help bounce the light around, put a slotted piece of 1x2 in the bottom for the mail to sit upright, exposed to the most light. Bet they'd sell on Ebay

Anything would sell on eBay in this panic.

Glad you did it for fun but Can coronavirus travel though the mail? Experts say no
