Far UV 222nm Upper-Room or Ceiling-Mount Disinfection Light

The Krypton-36 disinfection lights are ideal for rooms with high ceilings that range from 11 to 36 feet high. Far UV (222nm) Krypton-36 disinfection light can be used within almost any budget to increase the safety of occupants in any environment. Since it is unknown if the immune system of any occupant of space will be protective against viral infection, the goal is to reduce the ambient viral load in the space as much as possible. The Krypton-36 disinfection light is a practical, safe, and effective disinfection method in sanitizing air and surfaces while space is occupied. Far UV light (at 222nm) is a safe UV wavelength for human exposure. Please click here to learn more about the Far UV 222nm technology or refer to our FAQ page for more information.
