Do UV Lamps Kill the SARS-CoV-2 Virus That Causes COVID-19?

Ultraviolet (UV) light is a type of electromagnetic radiation that has more energy than visible light but less energy than x-rays and gamma rays. UV light from the sun is replicated in UV lamps for things like tanning beds and disinfection applications. UV light is broken down into different spectrums mainly UVA, UVB and UVC light. 

UVC light is the wavelength with germicidal effectiveness and is mostly absorbed by the Earth’s ozone layer before it reaches the ground. UVC germicidal lamps are designed to emit wavelengths at the optimal nanometer to kill germs which is typically 254 nm or 185 nm for ozone lamps.  According to the study Upper-room ultraviolet air disinfection might help to reduce COVID-19 transmission in buildings: a feasibility study by the National Institutes of Health, several studies have demonstrated that the SARS-CoV-2 virus that causes COVID-19 is relatively easily inactivated by UVC disinfection lamps similar to other airborne coronaviruses.  Additionally, conclusions from this study state that Upper Room Ultraviolet Germicidal Irradiation (UVGI) with UV light at 254 nm has the potential to inhibit the transmission of COVID especially in confined places like hospital rooms or public places or anywhere that achieving a high ventilation rate is not practical.

UV Lamps in HVAC Systems Fight Spread of Disease

The use of ultraviolet (UV) light in disinfecting and sterilizing surfaces is gaining as part of the fight against the spread of the novel coronavirus and to control health acquired infections (HAIs) in hospitals. HAIs are a serious problem for hospitals, especially when stretched at capacity and short on staff.  Even prior to the COVID-19 pandemic, nearly 1 in 25 patients were estimated to contract an HAI from a hospital stay, some with dire consequences. Protecting patients and staff against HAIs including drug-resistant bacteria and serious viruses with effective hospital disinfection is top priority for hospitals and healthcare facilities. 

Nearly everything that is in a hospital room from all the surfaces to airborne particles, medical equipment and the clothing and hands of healthcare workers can serve as a reservoir and vector for transmitting opportunistic pathogens.  While contaminated surfaces and insufficient hand hygiene are the primary modes of transmission, water and air supply systems also provide a mode of transmitting harmful pathogens.

UVC HVAC Air Purification Systems

While maintaining regular cleaning and manual disinfection practices is crucial in hospitals, along with proper hand hygiene, germicidal UVC lamps in moving air applications are proven to disinfect and purify the air. Ultraviolet Devices, Inc, UVDI, offers HVAC air disinfection and purification systems with advanced UV technology.
