An air sanitizer is a sanitizer that acts on airborne microbiological organisms or microorganisms. In the United States, a sanitizer is a disinfectant that is intended to disinfect or sanitize, reducing or mitigating growth or development of microbiological organisms including bacteria, fungi or viruses on inanimate surfaces in the household, institutional, and/or commercial environment and whose labeled directions for use result in the product being discharged to publicly owned treatment works (POTWs).
