How Does Germicidal UV Light Work?

September 08, 2020

You probably know that the sun’s ultraviolet light (UV) causes painful sunburn. But were you aware that a different type of ultraviolet light can be installed to keep your residence’s air clean?

The sun lets off two types of harmful UV rays, UVA and UVB. These dangerous rays can cause sunburn, skin cancer, wrinkles and other types of premature aging.

There’s another variety of UV light, called UVC. While full exposure to this ultraviolet light isn’t good for your skin or eyes, it can safely be applied to clean air, water and some surfaces.

Air Alliance Team uses this light in a few of our solutions to better air filtration in Ballwin and St. Charles houses.

What is an Ultraviolet Light Used For?

This specific wavelength is called “germicidal” because it kills the DNA of bacteria and viruses. When pathogens move through this light, they eventually die because they can’t spread.

This makes UVC light a strong replacement to chemical disinfection. Germicidal light is employed in many disinfection uses, like medical laboratories and hospitals. It’s also applied to purify drinking water and other liquids created in food processing.

It’s becoming a popular choice to disinfect air in residences in Ballwin and St. Charles. That’s due to the fact it can also eliminate typical indoor contaminants like mold, mildew and bacteria. This is an additional advantage if someone in your household has seasonal allergies or asthma.

Using Germicidal UV Light in Your House

We place a germicidal UV light in your HVAC system’s ductwork. Because the light is installed within the ductwork, it makes it compatible with many heating and cooling systems. This also keeps its beams securely contained while giving strong cleaning for your home’s air.

Dirty air is purified in a two-step process, first moving through your air filter and then the UV light before moving across your home. Even when your heat or air conditioning isn’t on, these lights still work to keep your air, ductwork and home comfort unit clean.

This whole-house solution is better than a portable air purifier, which is limited to cleaning the air in a lone space. Portable air purifiers also can’t freshen your ductwork or the innerworkings of your HVAC equipment. A clean HVAC system is typically a more efficient one that could even run longer. And, many portable air purifiers are notorious for making ozone.

When thinking about getting a germicidal lamp for your house, it’s critical to select one that doesn’t create ozone. While ozone is fantastic at getting rid of odors and chemicals, it may also irritate your lungs and lead to other respiratory symptoms.
