Here Are The Top 10 Best Large Room Air Purifiers 2022

Our list of the latest large room air purifiers includes only air purifiers that satisfy these specifications:
  • AlphaChooser considers that the most interesting metric to identify large air purifiers is their clean air delivery rate (CADR) figure. We set the bar for this list of the best large room air purifiers to a minimum CADR for dust of 230 cubic feet per minute.
  • Since the CADR rate is not provided by so many manufacturers, this list remains limited, simply because we list other rather large air purifiers, but for which we could not find the CADR. For that reason, you may want to take a look at our full list of True HEPA air purifiers too, because it contains other models.
