Yes, but presenting it as an alternative to masks and other behavioral changes is not useful. Cloth masks still work to stop droplets.

I have never seen a single person in any field say HVAC works over masks.

I have not seen a single person argue that HVAC is a substitute for other mitigation measures. In fact, every aerosol scientist I've seen has gone out of their way to emphasize ventilation as a *complement* to masking, distancing, etc. The resentment here is unwarranted. 1/

What has been clear from the beginning is that some in various disciplines have been resistant to acknowledging the significant role that aerosol transmission plays or accepting the contributions of aerosol scientists/engineers in developing a robust mitigation strategy. 2/

It is crucial that experts across these areas work together, and it is frustrating for the public to see this kind of territorial bickering. It is counterproductive and erodes public confidence in a diverse group of experts, all of whom are valuable and desperately needed.

I agree on working together, but my original tweet was born out of seeing engineers attacking virologists on Twitter and elsewhere. The aerosol debate is also counterproductive because it convinces people that cloth masks aren't worth the inconvenience.

Again, you are incorrect in "quoting" engineers. There are MANY pubs showing cloth masks work well in filtering aerosols that have been tweeted over and over. I have not seen one tweet from eng saying cloth masks don't work. Quite the opposite. See

I didn't say engineers were saying that. But engineers on Twitter have presented HVAC as a solution for in-person school and indoor dining, specifically to keep people safe without masks on. And the public has heard a lot about regular masks vs N95s. cont.

So when ppl shift the conversation to emphasizing aerosol transmission, the public concludes: "If I don't have an N95, what's the point in wearing a mask?" Engineers aren't saying cloth masks don't work, but by emphasizing aerosols, they are leading laypeople to that conclusion.

I am pretty sure that is not what “the public” concludes, though. Sacrificing the imperfect because the perfect isn’t attainable seems more an expert or medical establishment ailment that a public problem.

The aerosol debate (is it a debate?) does not convince people cloth masks aren’t useful. If anything not talking about aerosols openly and clearly probably makes the public mistrust us all, and mistrust masks in total.
