Indoor air UV disinfection is achieved by installing germicidal ultraviolet lamps in the air handlers, in the air ducts or directly inside the rooms.

Environmental surfaces are disinfected by permanently installed UV fixtures or mobile room disinfection UV systems while the rooms are unoccupied.

Water disinfection occurs in special chambers with one or more UV lamps inside with the water piped through the chamber.

Germicidal UV is an accepted alternative to pasteurization for inactivating of pathogens and other microorganisms which shorten the shelf life of beverages and foods.
