Upper Air Room Disinfection Solution

Built on Honeywell IAQ legacy, the ‘U’-PRISM solution offers better air disinfection and improved indoor air quality, reduces risk of cross infection due to contagious airborne pathogens. With Honeywell’s expertise in IAQ and optics, ‘U’-Prism is designed to deactivate upto 99%* of airborne pathogens. The product is subject to stringent testing and quality checks that is in accordance to NIOSH safety guidelines, ensuring safety to occupants and achieves continuous air disinfection in the room.

How does 'U'-Prism by Honeywell work?

Upper room air disinfection using UV-C is a technology used to reduce airborne pathogens and cross infections. A UV lamp in a specially designed fixture directs UV energy to the upper area of the room. The convective air currents push the pathogens present in the lower area to the upper part. The powerful UV-’C’ rays causes DNA/RNA damage to the pathogens there by inactivating them and creating a sterile ‘Upper –Zone’ or ‘Deactivation Zone’. Pathogen inactivation is exhibited over multiple passes and the microbial load is diluted over a period of time. This is a 24x7 cycle, providing continuous air disinfection for the facility.

False/True Ceiling recommended height - 9 ft
Natural convection/air movement to carry the lower section of the air to upper section
With UV rays directly concentrating on the upper air section
Air again moves down completing the process
The process is repeated multiple times
U-Prism Recommended Installation Height is 7.5 ft From Floor Level
Lower Air Contaminated Zone
Upper Air Sterile Zone

    Safety is Priceless!

    ‘U’-Prism by Honeywell is extensively tested and designed for optimum performance, suitable for upto 250 Sq ft area in verticals such as Healthcare, Commercial Buildings, Educational Institutes, etc.
