    Ultraviolet germicidal irradiation, or UVGI, is the use of ultraviolet (UV) energy to kill viral, bacterial, and fungal organisms. UVGI fixtures produce UV-C energy, which has shorter wavelengths than more penetrating UV-A and UV-B rays and pose less risk to human health. Upper-room UVGI refers to a disinfection zone of UV energy that is located ab...

    Air passes through the disinfection zone from air flow through HVAC system, fans, and/or open windows.
    The airborne pathogens are killed once they receive an appropriate amount of UV energy. The particles remain in the air, but they are no longer infectious.
    The most important locations for UVGI are high-risk indoor settings. These include:
    UVGI is especially recommended in spaces with insufficient or no mechanical HVAC systems or where adequate natural ventilation cannot be maintained year-round. Spaces must be at least 8 feet tall,...
    If the HVAC system allows for efficient filtrationor provides outdoor air flow above minimum code requirements, it will remove most airborne virus particles and upper-room UVGI would not add as muc...

    Upper-room UVGI has been used for over 70 years to eliminate airborne pathogens. Since 1950, the bulk of the research on upper-room UVGI systems focused on controlling the spread of tuberculosis (TB). Current guidance [6 MB, 87 pages]from CDC and National Institute for Occupational Safety and Health (NIOSH) on the design, installation, testing, and...

  3. The International Ultraviolet Association (IUVA) believes that UV disinfection technologies can play a role in a multiple barrier approach to reducing the transmission of the virus causing COVID-19, SARS-CoV-2, based on current disinfection data and empirical evidence.

  4. Oct 22, 2020 · UVC light can effectively kill SARS-CoV-2, the new coronavirus that causes COVID-19. Much of the research on this topic focuses on far-UVC light.

  5. Sep 8, 2022 · CLAIM UV light destroys the novel coronavirus that causes COVID-19. FINDING TRUE. Specifically, UVC light has been shown to quickly inactivate the novel coronavirus, SARS-CoV-2. It can be an effective disinfectant but needs to be used correctly to avoid damage to the skin and eyes.

  6. Jan 11, 2024 · New research has revealed how ultraviolet light destroys infectious virus particles. The knowledge could help develop new technology to disinfect hard-to-clean surfaces or equipment. Damaging the virus. The virus that causes COVID-19 is known as SARS-CoV-2.
