Also, fangen wir mal hinten an, Ich werde jetzt nach und nach #Literatur zu den #Luftreinigern twittern, um die Diskussion zu substantivieren.

I'll do that mainly in English, at times in German.

Let's start. (AC-1) Nature News, October 2021.

Of course, this is only a #News article in @Nature. The paper, at that time only a preprint, now appeared here:

In this work, authos state "Here we present
the first data providing evidence for the removal of SARS-CoV-2 and microbial bioaerosols from the air using portable air filters with UV sterilization on a COVID-19 ward."

I think this is true, in the paper actually particles...

1/ Interesting paper showing high efficacy of portable HEPA #filtration to reduce aerosol concentration in a high school classroom during use.

By very experienced German aerosol group Curtius et al.; via @ASTJournal.

With short🧵on room air filtration.
doi.org/10.1080/027868…
2/ "In times when classes were conducted with windows and door closed, the aerosol concentration was reduced by more than 90% within less than 30 min. when running the purifiers (air exchange rate 5.5 ACH). The reduction was homogeneous throughout the room ..."
[note log y-scale]
3/ Figure 3: Highly reproducible reduction in aerosol particle concentration [uCPC] in a closed classroom without air purifiers (blue line) and with 3 or 4 air purifiers operating at speed 3 or 4 (max).
