During a crisis, gimmicks can replace tried and true methods. As businesses and the general population look to remedy the health and safety issues of COVID-19, many have turned to ultraviolet (UV) light to help inactivate the airborne viruses.
UV Light Is ‘Potentially Hazardous’
While UV light is used as a disinfectant in hospital’s non-occupied spaces, it is not a credible solution to fight airborne viruses like COVID-19 in populated indoor spaces. UV light is harmful and increased exposure can cause health issues. In addition, any use of ultraviolet light in populated spaces should pass the burden of proof provided by the National Toxicology Program’s 14th Report on Carcinogens.
This is the primary reason that UV light should not be used as a primary tool to fight COVID-19 and other airborne viruses.
Despite the best intentions of businesses to keep patrons safe, using a quick scan of UV lights as patrons enter their business to inactivate COVID-19 aerosols does little to reduce the risk and could be harmful. In these short bursts, users would have to be exposed to high levels of UV light that would likely be harmful in order to be effective.
“However, UV portals that are meant to disinfect people as they enter indoor spaces are likely ineffective and potentially hazardous,” said Dr. Karl Linden, Ph.D., University of Colorado Boulder.
Adding UV light onto your ducts is proven to inactivate airborne viruses that flow through the ducts, but these add-ons are expensive and less beneficial than a MERV 16 or HEPA filter.
Alternatively, an Aprilaire Healthy Air System TM, a three-part, award-winning suite of whole-home Indoor Air Quality products, do not add any ozone or other harmful radiation levels into the air. It can be used in populated indoor spaces to help fight COVID-19 without any increased risk to the population.
By leveraging the power of humidity control, fresh air ventilation, and air filtration, you can help reduce the transmission rate of airborne viruses like COVID-19.
Humidity control allows you to keep your home between 30-60 percent relative humidity. This is the optimal range where viruses remain less viable and your body’s natural defenses and immune response are most viable.
Fresh air ventilation dilutes the home of particles and germs and fills your home with fresh, breathable air while maintaining airflow. According to the National Center for Biotechnology Information of the National Institutes of Health, ventilation is an important tool in reducing airborne pollutants in indoor air.
Air filtration captures particles that flow through the home and the filter. An Aprilaire MERV 16 filter captures up to 96% of airborne virus-sized particles passing through the filtering system.
