Does the Friedrich C90B Air Cleaner produce ozone?
Like a fax machine or copier, the Friedrich C90B does produce minimal amounts of ozone during operation. The maximum allowable indoor concentration recommended by the Food and Drug Administration (FDA) and American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) is .050 parts per minute (PPM). However, the Friedrich C90Bs highest ozone level measured was only .014 PPM.
