      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. Better answer: follow @jljcolorado @ShellyMBoulder @kprather88https://twitter.com/__apf__/status/1292085934767316997 …

      I wish there were guidance on whether high quality HEPA air purifiers that change the air several times an hour are useful indoors, and when or whether that's better than opening windows. (In winter, are we going to need to freeze, or will air purifiers substitute?)

      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 …

      7/ Selecting HEPA cleaner, DO NOT want ones that also have UV, ions or other bells-and-whistles. More $, don’t help, can be dangerous (see below). Filter already capturing the virus, which will decay there. Just change filter carefully, put in sealed bag, wash hands

      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 …

      Fourth option: it's more that person's problem than people around them. The virus seems to mostly spread *out* in drops of various sizes through the mouth, but is inhaled *in* and attaches well to the ACE2 receptors in the nose. Mouth-only mask is less protection for the wearer.

      Same dynamics that led to misrepresentation of mask research early on—ignoring evidence (a-presymptomatic spread), making baseless claims (false sense of security/harm), treating the public like children, lack of clarity on evidence to action etc. are in-play with ventilation.🙄

      "More research is needed." Yep, as usual. Just like with masks in March, there's a preponderance of evidence to act on ventilation. The answer to shortages was to treat the public as a partner & adults who deserve information; the answer to "don't scare the public" is.. the same.

      zeynep tufekci Retweeted Brian Resnick

      FWIW, the reason I got into ventilation/short-range aerosol research was what I heard from *epidemiologists* first who decisively argued that that epi data was the strongest reason to suspect this mode of transmission. This isn't a US-only conversation!https://twitter.com/B_resnick/status/1293934375009165312 …

      zeynep tufekci added,

      Brian ResnickVerified account @B_resnick
      Epis ask: "what are the patterns of contagion we're actually observing, and which known model do they fit?" Engineers ask: "what are the physics/mechanics of disease spread, and can we observe it, experimentally?"

      That engineers are arguing for aerosol transmission while Epi/ID folks are against works only if one cherry-picks examples plus ignores countries with top-notch experts and solid track record outside the US/EU. Even here, despite disagreements, the consensus/overlap isn't small.

      This week, the WHO is holding a "wear-a-mask" challenge and our outlets are writing a "how did the WHO/US/CDC/UK/EU/media got it so wrong" articles. How about we do better this time and practice evidence-based causal inference and communication that treats the public like adults?

      Honestly, the idea that there's some sort of engineers vs. epidemiologists/infectious-disease specialists divide on airborne/aerosol transmission is just not true the moment you step out into the world. Japan, Hong Kong, South Korea, Taiwan.. US is just behind, again, that's all.

      There is an overall infantilization going on here in the US...it’s related to the upsurge in authoritarianism. I’m writing about an aspect of it.
