How Does Germicidal UV Light Work?

September 08, 2020

Perhaps you realize that the sun’s ultraviolet light (UV) results in painful sunburn. But were you aware that another variety of ultraviolet light can be useful for keeping your residence’s air clean?

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

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

Airmen HVAC Service uses this light in some of our systems to enhance air filtration in Montoursville residences.

Applications for Ultraviolet Light

This precise wavelength is classified as “germicidal” because it wipes out the DNA of bacteria and viruses. When pathogens pass through this light, they eventually perish as they can’t spread.

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

It’s growing in popularity to freshen air in residences in Montoursville. That’s since it can also eradicate frequent indoor contaminants including mold, mildew and bacteria. This is an additional benefit for family members who suffer from seasonal allergies or asthma.

Uses for Germicidal UV Light in Your Home

We place a germicidal UV light within your HVAC system’s ductwork. As the light is put within the ductwork, it makes it compatible with most heating and cooling units. This also keeps its beams carefully restricted while providing strong cleaning for your home’s air.

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

This whole-house option is greater than a portable air purifier, which can only clean the air in a lone room. Portable air purifiers also can’t clean your ductwork or the innerworkings of your HVAC equipment. A clean HVAC system is often a more efficient one that could even operate for a longer life span. And, some portable air purifiers are known for making ozone.

When thinking over getting a germicidal lamp for your residence, it’s important to get one that doesn’t create ozone. While ozone is fantastic at eliminating odors and chemicals, it can also irritate your lungs and cause other respiratory issues.
