Covid-19 has led to a rapid development in the use of UVC LED technology for air disinfection. Aerosol transmission is now widely accepted as the principal way that COVID‐19 is spread, and the importance of ventilation, both natural and mechanical, is widely understood. This has driven a need for safer and more efficient air disinfection, particularly in high traffic areas such as airports, hospitals and theatres.
Airborne microorganisms such as viruses, bacteria, yeasts and mold can jeopardize people’s health, contaminate raw materials, and cause food to spoil. Disinfecting air in the supply air ducts ensures reduction of microorganisms for the long term.
However, air conditioning systems are designed for comfort, and cannot achieve the level of air changes recommended for airborne infection control. SARS‐CoV‐2 and other microorganisms are highly susceptible to UV, that has been shown to safely, quietly, effectively and economically produce the equivalent of 10 to 20 or more air changes per hour under real life conditions.
