How Does Germicidal UV Light Work?

September 08, 2020

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

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

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

Jett's Heating & Air Inc. uses this light in several of our systems to better air filtration in McHenry houses.

Applications for Ultraviolet Light

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

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

It’s growing in popularity to freshen air in houses in McHenry. That’s due to the fact it can also eliminate typical indoor contaminants such as mold, mildew and bacteria. This is an added benefit for loved ones who deal with seasonal allergies or asthma.

Installing Germicidal UV Light in Your Home

We place a germicidal UV light within your HVAC system’s ductwork. Since the light is installed in the ductwork, it makes it compatible with most heating and cooling units. This also keeps its beams safely housed while providing powerful cleaning for your house’s air.

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

This whole-house solution is better than a portable air purifier, which is restricted to cleaning the air in a lone room. Portable air purifiers also can’t freshen your ductwork or the interior of your HVAC unit. A clean HVAC system is typically a more efficient one that could even run for a longer life span. And, the majority of portable air purifiers are known for producing 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 great at getting rid of odors and chemicals, it could also irritate your lungs and cause other respiratory symptoms.
