AHAM’s “two-thirds” rule is to choose an air cleaner whose smoke CADR rating is two-thirds the size of the room’s area; its example is that a 200 square foot room needs a smoke CADR of at least 132. For wildfire smoke AHAM recommends a smoke CADR equal to the room’s size in square feet.
The EPA says the CADR rating system is for particles only, and that to filter gases you need an activated carbon filter or another filter designed to remove gases. It also says ozone generators sold as air cleaners intentionally produce ozone and that no federal agency has approved them for occupied spaces; it says the California Air Resources Board and AHAM maintain lists of air cleaners tested and shown to emit little or no ozone.
