AIR DISINFECTION – GUV OPTIONS

Upper Room Air Disinfection

• Inactivates virus directly in the room – safest option for occupants. • Permanent fixtures mounted above 7 feet continuously disinfect air in the space. • Best if used with low velocity ceiling fan to circulate air through the disinfection zone. • Saves energy. Only a couple of watts per room is needed. • Occupants should avoid direct exposure. Maintenance staff must be trained in safely operating the system.

Unoccupied Air Disinfection

• Robots using high powered pulsing xenon lamps can disinfect air after hours. • Not recommended for primary surface disinfection – hard to get direct access to all surfaces. Chemical disinfection has many advantages. • Doesn’t help during occupied hours.
