UVC Light

UVC light is a type of ultraviolet light in the 200-280 nanometer wavelength range, known for its ability to disinfect by destroying the DNA or RNA of microorganisms like viruses, bacteria, and mold. When these pathogens are exposed to UVC light, they become inactive and unable to replicate, making UVC an effective tool for improving air quality and surface cleanliness in various environments, including schools, offices, and healthcare facilities.

Yes, UVC light is safe when used properly. Airtech’s UVC solutions are designed with safety in mind, ensuring that UVC light is contained within devices like air purifiers and upper-room systems. These products are engineered to prevent direct exposure to people, making them suitable for continuous use in occupied spaces such as classrooms, offices, and patient areas in healthcare facilities.

UVC light is highly effective at inactivating a wide range of viruses, including those responsible for COVID-19. Studies have demonstrated that UVC light can inactivate up to 99.9% of viruses and bacteria by disrupting their genetic material. While UVC is a powerful tool in the fight against airborne and surface pathogens, it should be part of a comprehensive approach to hygiene that includes cleaning and ventilation.

Yes, Airtech’s UVC air purifiers are designed for safe use in occupied spaces such as classrooms, office areas, and healthcare facilities. These devices contain the UVC light within enclosed systems, ensuring no harmful exposure to people. For surface disinfection, UVC light is most effective when used in unoccupied spaces, such as during off-hours or between shifts.

UVC light complements traditional cleaning and disinfection methods by targeting airborne and surface microorganisms that manual cleaning may not fully address. While cleaning removes visible dirt and contaminants, UVC light neutralizes pathogens at a microscopic level, providing a more comprehensive approach to maintaining a clean and healthy environment in schools, businesses, and healthcare facilities.

Airtech’s UVC devices require regular maintenance to ensure they operate at peak efficiency. Typically, UVC lamps need to be replaced annually, depending on the intensity and duration of use. Our team provides maintenance services and can work with you to establish a maintenance schedule that suits your facility’s needs.

ASHRAE Standard 241, Control of Infectious Aerosols, establishes guidelines to reduce disease transmission through exposure to infectious aerosols in new and existing buildings. Implemented in the USA in 2023, this standard is likely to be adopted in New Zealand in the coming years.  Visit the ASHRAE website to find out more.
