UV Diffusers, designed by EffectiV HVAC Inc., Montreal, Quebec, are a solution to contain the spread of COVID-19 through ventilation systems using UVC light, which purifies the air around us through combined high-efficiency filtering, sanitizing and diffusion of the air coming from the building ventilation system. When in operation, the three-in-one solution helps to contain the spread of COVID-19 and other airborne diseases in commercial and public buildings. At the heart of the operation is their unique plenum which integrates ozone-free UV lamps and its design to increase air contact with UVC light helping to neutralize 100% of COVID-19, Tuberculosis, Legionella and other pathogens. “Our UV solutions ensure clean and safe air in every room of the building and can sterilize pathogens with an efficiency of up to 100% based on the amount of airflow,” said EffectiV HVAC spokesman Frank Godbout.
