The M-Series™ UV system provides maximum UVC germicidal disinfection for ductless air conditioning units found in hotels, motels, medical offices, homes, apartments, and condos. The high-intensity germicidal UV light kills microorganisms such as mold and bacteria that grow inside the A/C unit as well as helps reduce the airborne contaminants such as germs, viruses, and allergens passing through the HVAC system.
