Exactly. Aerosols are like short-range mist—the closer you are to the person emitting it, the more exposure *but* under the right conditions (poorly ventilated indoors space), the mist can accumulate and even be pushed around by air currents beyond 6 feet. https://twitter.com/dylanhmorris/status/1289612851762667521
What it's like to be a woman writing about tech/science/society. Two things happened the same day, and one of them is random dude telling me I "clearly have no clue" about airborne spread, just after I wrote a ~5K article about it. No track record is ever good enough for women.
Because of my piece on ventilation, I keep getting asked for practical advice. CDC and health authorities should update guidelines. But for individuals? I'd say avoid Japan's 3Cs: closed spaces, crowded places, close-range conversations. And wear masks. https://www.theatlantic.com/health/archive/2020/07/why-arent-we-talking-more-about-airborne-transmission/614737/
Pandemic theater. Broncos players are coming out of an *indoors* locker room, to pant at each other at close range, but not before being sprayed by, uh, mumbo-jumbo nano-crystalline disinfectants!. (Do more! Activate the holosensors! Use positronic beams too!)

I mean if we’re going to do pandemic theater, at least let’s do it right, with some elegance amd history. My grandmother would’ve put an evil eye charm on all of them.

Write an article about aerosols, get a LinkedIn inbox that feels like who's who of HVAC/IAQ companies.
No I can't endorse products. But my own AC is on the fritz? (And my landlord is trying to evict me, so not going corrupt and helping fix his AC for free at the same time!)

YES! Dr. Fauci acknowledges some aerosolization. Says indoor/outdoor different, indoors "much greater risk than outside.” Emphasizes "mask-wearing indoors." Acknowledges ~5-10 μm can float, says they likely got that wrong.Now, hopefully new guidelines! https://www.cnbc.com/2020/08/03/fauci-says-theres-a-degree-the-coronavirus-is-spreading-through-air-particles.html

Thrilled to see the message about the importance of ventilation *finally* breaking through to the broader public (at least, I hope so!). (Sane policies for/media coverage of the safer activities outdoors, maybe, too, one can hope?) https://twitter.com/misguidedsoul7/status/1291069337600774144
Why important to understand the role aerosols may play correctly even though they, too, cluster in close-range of the person. Droplets=only in front of one. Aerosols=escape behind one if mask is poorly fitting. Keep your mask on indoors even at distance. https://twitter.com/jljcolorado/status/1280935408398766080
Short answer: Hepa filters with no gimmicks (ionizer, UV) are good for unventilated spaces. Higher CADR (smoke rating) is better. If you can open windows/doors for good air circulation, better.

Thread below with some answers. Also more experts to follow: @linseymarr, @corsiaq, @JimRosenthal4, @stephensbrent. That said, it's past time for CDC to step up and give us guidance on ventilation. As I wrote, Japan has been doing that since the beginning. https://twitter.com/jljcolorado/status/1291760621822726145
The dearth of communication from health authorities on even the most basic questions like the one below is maddening. The few experts on social media are doing what they can, but it's really time for the academy to form it's own shadow CDC to communicate. https://twitter.com/zeynep/status/1291777886014365696
