Health Canada is concerned with the adverse health effects that may result from the deliberate exposure of the public to ozone from air cleaners that intentionally generate ozone gas.
Ozone is an irritant that can cause coughs, chest discomfort, and irritation of the nose and throat.
The direct and purposeful generation of ozone indoors should be avoided. Health Canada advises all owners of ozone generators to stop using them in their homes. Owners of commercial ozone generators are advised to either discontinue use or have their devices tested to ensure that recommended exposure levels for ozone are not exceeded. Commercial ozone generators should never be used in homes. The units have one or more control knobs or switches on the front face.
