How Germicidal UV Light Works

You likely are aware that the sun’s ultraviolet light (UV) results in painful sunburn. But did you realize that another kind of ultraviolet light can be installed to keep your house’s air clean?

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

There’s another type of UV light, called UVC. While unprotected exposure to this ultraviolet light is bad for your skin or eyes, it can safely be utilized to clean air, water and some surfaces.

Oak Point Heating and Air LLC uses this light in a few of our systems to better air filtration in Denton homes.

How Ultraviolet Light is Used

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

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

It’s growing in popularity to purify air in residences in Denton. That’s because it can also eradicate typical indoor contaminants including mold, mildew and bacteria. This is an additional benefit for loved ones who deal with seasonal allergies or asthma.

Uses for Germicidal UV Light in Your Home

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

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

This whole-house option is better than a portable air purifier, which can only clean the air in one area. Portable air purifiers also can’t purify your ductwork or the inside of your HVAC system. A clean HVAC system is typically a more efficient one that can even last for an extended period of time. And, some portable air purifiers have a bad reputation for making ozone.

When thinking about adding a germicidal lamp to your home, it’s critical to get one that doesn’t create ozone. While ozone is fantastic at wiping out odors and chemicals, it can also irritate your lungs and create other respiratory problems.
