Air Changes per Hour

Air changes =  CFM (60) / Cu ft   Room: 10’ x 8’ x 8’ ceilings = 640 cu ft  Airflow:  534 CFM + 365 CFM = 899 CFM  899(60) = 53,940/640 cu ft = 84 air changes per hr

Filter testing

HEPA filter balance: Measuring CFM, FPM, and adjusting if needed Room pressure adjustment if needed HEPA/ULPA leak testing: Establish a uniform PAO aerosol challenge upstream, this can be measured or calculated. Concentration between 10µg and 90µg. 20µg is optimal for this testing. Using the phot...
