You can check this list to get an idea of how much CFM the best air purifiers can produce for reference It is also interesting to see how the CADR rating for dust removing air purifiers depends on airflow You can freely use the CFM calculator to calculate airflow for any room and for any ACH Answer 1 350 400 CFM per ton of HVAC capacity That s the answer to the question What CFM do I need for my HVAC system to do its job This answer of 350 400 cubic feet per minute for each 12 000 BTUs of AC cooling is optimal for the system to run efficiently while adequately cooling and dehumidifying the space 12 000 BTUs 1 Ton
