How Does Germicidal UV Light Work?

September 08, 2020

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 used to keep your house’s air clean?

The sun gives off two types of harmful UV rays, UVA and UVB. These harmful rays can lead to 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 is harmful for your skin or eyes, it can safely be applied to disinfect air, water and various surfaces.

Stieferman Heating Company Inc uses this light in some of our systems to better air filtration in Jefferson City residences.

Applications for Ultraviolet Light

This distinct wavelength is called “germicidal” because it wipes out the DNA of bacteria and viruses. When pathogens travel 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 many disinfection uses, like medical laboratories and hospitals. It’s also applied to clean drinking water and other liquids created in food processing.

It’s becoming more popular to freshen air in houses in Jefferson City. That’s because it can also wipe out typical indoor contaminants including mold, mildew and bacteria. This is an additional perk if someone in your household has seasonal allergies or asthma.

Uses for Germicidal UV Light in Your Residence

We place a germicidal UV light in your HVAC system’s ductwork. Because the light is put inside the ductwork, it makes it compatible with most heating and cooling equipment. This also keeps its light carefully confined while delivering strong disinfection for your residence’s air.

Contaminated air is cleaned in a two-step process, first moving through your air filter and then the UV light in advance of spreading around your home. Even when your heat or air conditioning isn’t running, these lights still work to keep your air, ductwork and home comfort system clean.

This whole-house solution is superior to a portable air purifier, which is limited to cleaning the air in a lone room. Portable air purifiers also can’t freshen your ductwork or the interior of your HVAC equipment. A clean HVAC system is usually a more efficient one that can even last longer. And, the majority of portable air purifiers are notorious for making ozone.

When considering getting a germicidal lamp for your house, it’s critical to get one that doesn’t create ozone. While ozone is great at eliminating odors and chemicals, it can also irritate your lungs and create other respiratory problems.
