There are many benefits to sterilizing surfaces with UV light in addition to a highly effective kill rate of viruses and bacteria. While surfaces should still be cleaned with manual cleaning methods to ensure a clean surface free from organic compounds prior to UV exposure, by adding UV light disinfection to your cleaning regimen you can ensure a higher level of protection against disease without the use of additional chemicals.
UV radiation on food is highly beneficial in that there is no need to expose food items to chemicals to prevent infestations and foodborne illnesses. UV sterilization is extremely cost-efficient, operating 24/7 with no need for additional labor or maintenance. Surface sterilization is extremely effective and cost-efficient when using high-quality UVC germicidal lamps.
