Any recent PhD (2023 or later) aerosol scientists out there interested in studying airborne transmission of respiratory infections? My group is looking for a postdoc to work on human challenge studies with influenza virus at Emory University. Full description at drive.google.com/file/d/1HzJZ...

🧪Our new paper measuring the bio inactivation by Far UVC is out. We look at ventilation rate, two bacteria (S aureus, P aeruginosa) and some initial tests on distance www.sciencedirect.com/science/arti... 1/

Our latest paper on the efficacy of germicidal UV radiation just landed at Journal of Hazardous Materials. Thank-you JHM for a smooth peer review process. doi.org/10.1016/j.jh...

Thread for those new to BlueSky. First of all, welcome. It feels like a safer space, doesn’t it? But also perhaps a bit disorienting initially? Here’s some tips for getting your bearings.

No, SARS-CoV-2 isn’t a little bit airborne. It’s not “situationally” airborne. It’s an AIRBORNE VIRUS, spreads via the air. I’m granting an amnesty on people who said (5y ago) that it wasn’t. I won’t say I told you so if you finally acknowledge the evidence. Let’s just get this right and move on.

Latest from Vic health dept SM: Credit for acknowledging airborne transmission & educating about the importance of ventilation 👍 Nb: given they acknowledge transmission is airborne, advice to wear a respirator when ventilation is not optimal (eg crowded public indoor spaces) would’ve been helpful

Great paper on the theory of why not-HEPA is actually better. It makes two assumptions that I think need to be updated. My guess is with electret media, 90% is probably target 1. Doesn't consider electrostatic filter media 2. That blower efficiency curves are fixed, but still good first order est.

[1/2] All that matters is CADR! Ignore things super-hyper-mega HEPA. Often times a filter that only provides 70-80% actually provides more clean air than a filter that is 99.97%(HEPA). I used a 16x20 3M filter taped to a Taotronic AP-003(with no internal HEPA installed) and got a 30% boost in CADR.

This paper from 20 years ago has the math and theory for an greatly improved air cleaner design at ~80% filtration that has turned out to be correct. The "must be HEPA 99.97% filtration" is hard to overcome.

Steve Rudnick described the theory behind this phenomenon in a paper in Aerosol Science and Technology in 2004. For submicron particles, he estimated that 82% efficiency was optimal. www.tandfonline.com/doi/abs/10.1...

When it comes to the airborne transmission of viruses, how fast the air is physically removed from the room is important. In my latest explainer video, I discuss how you can measure how well your home is ventilated, and what you can do improve it. youtu.be/dMTOLgIc8-I #ventilation

The report released today by @saferairproject.bsky.social makes a strong case for safer shared air as an accessibility and inclusion issue. www.saferairproject.com/safer-shared...
