COVID-19 and the Benefits of UVC
Germicidal UVC has been used for well over 100+ years for its ability to combat viruses, bacteria, and spores. UVC has played a major role in inactivating pathogens such as Tuberculosis, Measles, and SARS in recent history. During the threat of a new, highly-contagious virus, COVID-19, UVC was at the forefront again, providing disinfection solutions.
What is UV-C and how does it work?
Ultraviolet light in the C spectrum (UV-C) is energy-rich light with a wavelength of 254 nanometers (nm). UV-C works by deactivating and damaging the DNA of bacteria, viruses and other pathogens and destroys their ability to multiply and cause disease.
How interested are businesses in UVC products? What was the interest pre-COVID vs. now?
Interest in UV-C significantly increased in 2020. Before COVID-19, interest was primarily focused on hospitals, correctional facilities, K-12 schools, universities, and energy saving projects. Not only did we see an increase of interest with these applications, but we also saw interest from all types of facilities looking to create safer environments for occupants, such as salons, grocery stores, restaurants, health clubs, and others. This resulted in starting new conversations in order to create new standards for indoor air quality, such as ASHRAE Standard 241-2023.
What impact can UVC have on a business?
The benefits of incorporating UVC technology can include improved performance of staff, reduction of illness and absenteeism, and peace of mind for customers. By continually inactivating pathogens in the air and on surfaces, businesses can provide a safer indoor environment for employees and patrons now and in the future.
What solutions does Lumalier offer for various applications?
We offer a broad range of products ranging from those that provide facility-wide disinfection to models engineered for emergency disinfection. In AHU & In Duct products, installed in air handling units (AHUs), offer facility-wide disinfection as the air is being distributed throughout the building. Upper-air products are for use in high-occupancy areas for targeted disinfection to mitigate the spread of pathogens from person to person. We also offer surface disinfection units in both fixed and portable options to ensure that cleaning protocols and practices are as efficient and as effective as possible.
What are the benefits to installing UVC equipment beyond the COVID-19 pandemic?
Reduction of HVAC maintenance, reduction of energy consumption, improved occupant performance, and reduction of sick days/absenteeism are all benefits of UVC applications.
How do you see UVC technology impacting people’s lives now and in the future?
We are providing one important solution to help create safer indoor spaces. In the future, we expect building codes to require proper, scientifically proven standards of UV-C for the safety, protection, and welfare of the building occupants.
Industry Expertise and Recommendations
What is ASHRAE (American Society of Heating, Refrigerating and Air Conditioning Engineers) saying?
UV technology is listed by ASHRAE as a viable solution to the spread of pathogens via airstreams.

Timely, helpful, problem-solving information.
“Air disinfection by means of UVGI could effectively reduce the amount of air changes required for infection control in a space provided by mechanical ventilation and save energy. Such air disinfection may be the single most cost-effective engineering intervention under circumstances where air circulation is an important transmission factor.” Read more >
