    (1/2) Are searching for an air cleaner? 1st, I recommend HEPA only for COVID risk mitigation indoors. Want to treat a 600 sq ft room? FYI an air cleaner with a CADR of around 400 cfm will give you 5 air changes of particulate-free air (assuming an 8 ft ceiling).

        (2/2) CADR (in cu ft/min) = room volume in cu ft x 5 air changes per hour / 60 min/h. See page 5 https://shellym80304.files.wordpress.com/2020/06/air-cleaner-report.pdf …

        Perfect timing for me. I was just trying to advise some clinical researchers on air cleaning for an indoor space. I didn't know what to recommend and now I do. Perfect. Will forward to my Dean as well.
