Do aerosol products cause or contribute to asthma?
No. According to a recent review of the scientific literature by the National Academy of Sciences, the only exposures known to cause asthma are house dust mites, cockroaches, cats and environmental tobacco smoke. Other exposures associated with increased asthma are dogs, rhinovirus, molds and nitrogen dioxides. Many aerosol products indeed are designed to lower exposures to these types of biological contaminants.
