How Does Germicidal UV Light Work?

September 08, 2020

You likely are aware that the sun’s ultraviolet light (UV) causes painful sunburn. But were you aware that another kind of ultraviolet light can be useful for keeping your house’s air clean?

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

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

Goode Bros AC & Heating uses this light in some of our products to boost air filtration in Longview homes.

What is an Ultraviolet Light Used For?

This distinct wavelength is referred to as “germicidal” as it wipes out the DNA of bacteria and viruses. When pathogens pass through this light, they eventually cease to exist since they can’t spread.

This makes UVC light a powerful alternative to chemical disinfection. Germicidal light is employed in lots of disinfection uses, like medical laboratories and hospitals. It’s also applied to sterilize drinking water and other liquids produced in food processing.

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

Uses for Germicidal UV Light in Your Home

We put a germicidal UV light within your HVAC system’s ductwork. Because the light is placed inside the ductwork, it makes it compatible with most heating and cooling equipment. This also keeps its light safely housed while giving strong disinfection for your home’s air.

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

This whole-house solution is better than a portable air purifier, which is restricted to cleaning the air in a single room. Portable air purifiers also can’t clean your ductwork or the innerworkings of your HVAC unit. A clean HVAC system is often a more efficient one that can even last for an extended period of time. And, many portable air purifiers have a bad reputation for creating ozone.

When considering buying a germicidal lamp for your residence, it’s important to select one that doesn’t make ozone. While ozone is great at eliminating odors and chemicals, it may also irritate your lungs and lead to other respiratory problems.
