During a pandemic flu one of the few ways to reduce the risk of spread to yourself or others is to trap the virus particles with an air purifier that is equipped with an ultraviolet light. As the virus is drawn into the purifier the ultraviolet light kills the airborne virus particles and germs before the filtrated air goes back into the room! A main cause of influenza is through inhalation of virus particles that are spread by sick people coughing and sneezing. An infected family member, visitor or co-worker can shed flu virus for two days before showing any symptoms.
