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 another kind of ultraviolet light can be used to keep your residence’s air clean?

The sun emits two types of damaging UV rays, UVA and UVB. These dangerous rays can cause sunburn, skin cancer, wrinkles and other signs of premature aging.

There’s another type of UV light, known as UVC. While direct exposure to this ultraviolet light is harmful for your skin or eyes, it can safely be applied to clean air, water and certain surfaces.

B & G HVAC uses this light in a few of our solutions to better air filtration in Marshalltown residences.

Applications for Ultraviolet Light

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

This makes UVC light a mighty alternative to chemical disinfection. Germicidal light is used in a lot of disinfection procedures, such as medical laboratories and hospitals. It’s also applied to clean drinking water and other liquids produced in food processing.

It’s growing in popularity to disinfect air in homes in Marshalltown. That’s because it can also wipe out frequent indoor contaminants like mold, mildew and bacteria. This is an extra benefit if someone in your household has seasonal allergies or asthma.

Using Germicidal UV Light in Your Home

We install a germicidal UV light within your HVAC system’s ductwork. As the light is set in the ductwork, it makes it compatible with most heating and cooling systems. This also keeps its light securely contained while giving great purification for your home’s air.

Dirty air is purified in a two-step process, first flowing through your air filter and then the UV light in advance of flowing around your house. Even when your heat or air conditioning isn’t working, these lights still operate to keep your air, ductwork and home comfort equipment clean.

This whole-house option is greater than a portable air purifier, which can only clean the air in one space. Portable air purifiers also can’t purify your ductwork or the innerworkings of your HVAC equipment. A clean HVAC system is usually a more efficient one that could even last longer. And, the majority of portable air purifiers are notorious for making ozone.

When considering adding a germicidal lamp to your home, it’s critical to select one that doesn’t create ozone. While ozone is fantastic at getting rid of odors and chemicals, it might also irritate your lungs and cause other respiratory troubles.
