EPA’s chart calls for about 195 CFM of CADR for 300 sq ft, 325 CFM for 500 sq ft and 390 CFM for 600 sq ft with 8-foot ceilings.
Count the filter cost
Check the price and life of the replacement filter before you buy. A cheap purifier with expensive filters can cost more over two years.
Run it faster and longer
EPA notes higher fan speeds and longer run times filter more air, so an oversized purifier on medium can beat a small one on high.
