How Does Germicidal UV Light Work?
Ultraviolet lamps are placed inside your ductwork, near your HVAC system, and run constantly. These lamps use ultraviolet radiation and special lightbulbs to alter the DNA of bacteria or viruses.
In as little as 10 seconds, this powerful light stops contaminants from replicating throughout your HVAC system and home. Without the ability to reproduce or replicate itself, contaminants will soon die off.
Two studies have shown how beneficial UV light is in fighting germs and mold. In 2012, researchers at Duke University Medical Center successfully used it to wipe out 97 percent of drug-resistant bacteria in 50 hospital rooms. And in 2001, researchers found UV light “significantly lowered” mold levels in a commercial office building’s HVAC equipment.
A germicidal system can also take care of scents and airborne bioaerosols like pollen or pet dander. It’s not effective against dust, which is best regulated by an air filtration system.
Is a UV Germicidal Light Safe?
Using UV light in your home is not dangerous as long as you stick to a couple of basic safety measures.
The sun lets off ultraviolet light, which has a shorter wavelength than visible light. It’s behind creating painful sunburns. Ongoing overexposure can result in wrinkles, skin cancer and eye problems.
The type of light used in a germicidal system is more powerful, so it’s important to let Broad Ripple Service Experts handle installation and maintenance. You should never look right at the light or permit bare skin touch it.
