Should You Use Air Purifiers with UV Light?

What Are Air-Cleaning UV Fixtures?

Our upper-air UV fixtures utilize enclosed UV-C lamps that continuously clean the air. Working together with ceiling fans, ACs, or HVAC systems, air in your space will be circulated through the disinfecting beam of light. The light combats airborne viruses, bacteria, and fungi, and is safe for use in occupied rooms.


  • No changes need to be made to your existing HVAC system.
  • Can safely be used in occupied rooms.
  • Best choice for reducing airborne transmission of microbes.


  • Does not disinfect surfaces.
  • Must be mounted on the wall or ceiling.

What does UV Light Do in Air Purifiers?

How it Works

Disinfection with ultraviolet light uses specific wavelengths (not chemicals) to inactivate pathogens. Ultraviolet (UV) light is germicidal, meaning it attacks the DNA structure of a variety of cell types, rendering them inactive.

Upper-room UV units have been used in hospitals, especially in tuberculosis wards, for decades. They have even been recognized by the World Health Organization and US Center for Disease Control as an important environmental control to reduce airborne TB transmission.

Are Air-Cleaning UV Lights Safe?

If used correctly, our UV air cleaners are 100% safe. Using any UV light products comes with some risk, but upper-air UV lights are safer than most other options. These fixtures can be safely operated in occupied rooms because the UV light is kept away from any occupants by facing up toward the ceiling or being completely contained in the unit.

Due to its cell-inactivating properties, prolonged, direct exposure to UV rays can be dangerous to humans or animals and can accelerate material degradation, so these devices should be used with care and only according to the included instructions.
