Filtered Far-UVC: Safe Sterilization for Public Spaces

SPONSORED BY:

UV sterilization is a method of disinfection that uses short-wavelength UVC light (in the 200-280nm range) to kill or inactivate bacteria, viruses, and protozoans by destroying the nucleic acids and disrupting their DNA. DNA absorbs the most light at about 260nm and proteins at about 220nm.

The use of UVC light for sterilization has been an accepted practice since around the mid-20th century and is used in applications ranging from medical sterilization to sterilizing work facilities and water and air treatment.

Early applications of UV sterilization used an unfiltered UV lamp inside an enclosure, but in newer applications where people are present in the space, UV filters are required to protect the occupants.

Research and use cases performed in recent years have demonstrated the proven safety of properly implemented, tested, certified, and filtered far-UVC for sterilization applications in public spaces.

This white paper offers an in-depth look at UV sterilization, including how the latest developments in filter technology have improved the safety of sterilization devices, as well as presents a number of use cases.
