How Germicidal UV Light Works

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

The sun gives off two types of damaging UV rays, UVA and UVB. These damaging rays can lead to sunburn, skin cancer, wrinkles and other types of premature aging.

There’s another concentration of UV light, known as UVC. While full exposure to this ultraviolet light isn’t good for your skin or eyes, it can safely be utilized to clean air, water and some surfaces.

B&D Air Conditioning uses this light in a few of our systems to enhance air filtration in Safford residences.

What is an Ultraviolet Light Used For?

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

This makes UVC light a powerful replacement to chemical disinfection. Germicidal light is employed in many disinfection applications, such as medical laboratories and hospitals. It’s also employed to purify drinking water and other liquids produced in food processing.

It’s becoming more popular to purify air in houses in Safford. That’s due to the fact it can also eradicate common indoor contaminants including mold, mildew and bacteria. This is an additional advantage if someone in your household has seasonal allergies or asthma.

Using Germicidal UV Light in Your Home

We install a germicidal UV light inside your HVAC system’s ductwork. As the light is set in the ductwork, it makes it compatible with many heating and cooling units. This also keeps its light carefully contained while delivering strong disinfection for your residence’s air.

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

This whole-house option is superior to a portable air purifier, which can only clean the air in one room. Portable air purifiers also can’t freshen your ductwork or the inside of your HVAC equipment. A clean HVAC system is typically a more efficient one that can even operate for an extended period of time. And, many portable air purifiers are known for producing ozone.

When thinking over buying a germicidal lamp for your home, it’s important to buy one that doesn’t create ozone. While ozone is good at eliminating odors and chemicals, it can also irritate your lungs and lead to other respiratory symptoms.
