Request to air purifier manufacturers (please reply here)
Demande aux fabricants de purificateurs.

Il est couteux de faire des boites de Corsi-Rosenthal en 🇫🇷 => les purificateurs d'air du commerce y sont compétitifs.

Vous savez le rôle que peuvent jouer les purificateurs d’air dans la lutte contre les maladies à virus comme le COVID-19, le VRS, la grippe…
Les critères importants sont:Â
- ACH (Air Change per Hour) = 6 (10 Ă l’hĂ´pital)Â
- Filtre HEPA 14 ou plus

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.

Like always Air Pollution becomes a topic of discussion when Delhi is facing it during crop fire season and it's eventually forgotten. Interestingly people also search for #AirPurifiers when #AirPollution also trends as shown in Google Search Trends
