Upper-room UVGI
Wall- or ceiling-mounted fixtures direct 254 nm germicidal UV-C into the space above head height. Room air moving through that zone is disinfected continuously while people use the room below.
- Wavelength
- 254 nm UV-C
- Mounting
- Above 7 ft, louvered so UV stays overhead
- Best for
- Waiting rooms, corridors, dining and activity rooms, shared resident rooms
- Room needs
- Ceilings of about 8 ft or higher and good air mixing
- Guidance
- CDC/NIOSH upper-room UVGI guidelines
We lay out each installation for the room's size, ceiling height and airflow, and commission it so occupants below stay within recognized UV exposure limits.
