How Does Germicidal UV Light Work?

September 08, 2020

You probably know that the sun’s ultraviolet light (UV) results in painful sunburn. But were you aware that another kind of ultraviolet light can be used to keep your house’s air clean?

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

There’s another variety of UV light, known as UVC. While full exposure to this ultraviolet light isn’t good for your skin or eyes, it can safely be used to disinfect air, water and certain surfaces.

Brandon Heating and Plumbing uses this light in a few of our products to enhance air filtration in Brandon residences.

Applications for Ultraviolet Light

This distinct wavelength is classified as “germicidal” as it kills the DNA of bacteria and viruses. When pathogens travel through this light, they eventually perish because they can’t multiply.

This makes UVC light a mighty alternative to chemical disinfection. Germicidal light is used in a lot of disinfection applications, including medical laboratories and hospitals. It’s also employed to clean drinking water and other liquids made in food processing.

It’s becoming a popular choice to disinfect air in homes in Brandon. That’s since it can also wipe out typical indoor contaminants such as mold, mildew and bacteria. This is an additional advantage for family members who suffer from seasonal allergies or asthma.

Having Germicidal UV Light in Your Home

We place a germicidal UV light within your HVAC system’s ductwork. Because the light is put within the ductwork, it makes it compatible with most heating and cooling systems. This also keeps its rays carefully restricted while giving powerful cleaning for your house’s air.

Contaminated air is cleaned in a two-step process, first flowing through your air filter and then the UV light before circulating around your house. Even when your heat or air conditioning isn’t operating, these lights still operate to keep your air, ductwork and home comfort system clean.

This whole-house option is greater than a portable air purifier, which is limited to cleaning the air in a lone area. Portable air purifiers also can’t freshen your ductwork or the innerworkings of your HVAC unit. A clean HVAC system is often a more efficient one that may even last for a longer life span. And, some portable air purifiers are notorious for making ozone.

When thinking over buying a germicidal lamp for your house, it’s essential to choose one that doesn’t create ozone. While ozone is good at eradicating odors and chemicals, it could also irritate your lungs and create other respiratory issues.
