Can UV Light Kill Coronavirus?

April 20, 2020

The coronavirus (SARS-CoV-2) has taken an unsuspecting World by storm, but the best thing the Triad community can do is be ready, and take some steps to prepare and fight back against this virus. So can installing a UV Light in your HVAC system kill the virus?

For several decades, it has been known by scientists that broad-spectrum germicidal UV light, with wavelengths between 200 and 400 nanometers (nm), is very effective at killing bacteria and viruses by destroying bonds that hold their DNA together. This standard
UV light is often used to decontaminate surgical equipment. The virus is sensitive to ultraviolet heat and light, so radiation from ultraviolet light can eliminate the virus effectively, according to the latest guideline on diagnosis and treatment of the coronavirus released by the National Health Commissions.

According to health guidelines, ultraviolet light should be used to disinfect indoor spaces with an intensity of 1.5 watts per square meter. A UV lamp can disinfect any object within one meter for at least thirty minutes.

In air conditioning systems, UV light destroys harmful microorganisms, including mold, mildew, fungi, bacteria, and viruses like SARS-CoV-19. You can incorporate these lights into your home air conditioning system. UV lights are typically installed near your primary AC coil or in your ductwork. Microorganisms that pass within the UV bulb’s line of sight will be destroyed.

UV lights are quite easy to install, though the job is best entrusted to a professional service technician. (An HVAC expert will know how to place the lights for maximum effectiveness.) Air conditioning UV lights are usually mounted with magnets. Bulbs last for roughly 12 months, and you can easily replace them yourself. The electricity required to run UV lights typically only costs about $2 per month.

I am confident that life will soon return to normal, and we will all be able to put this unpleasant time behind us. However, flu season and allergy season is nothing new to us here in the Triad and to help give your and your family some peace of mind when that time comes give L&H Heating and Air Conditioning a call to discuss the use of a UV Air Purifier in your homes heating and air conditioning system.
