How Does Germicidal UV Light Work?

September 08, 2020

Perhaps you realize that the sun’s ultraviolet light (UV) causes painful sunburn. But did you realize that a different type of ultraviolet light can be used to keep 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 types of premature aging.

There’s another variety of UV light, referred to as UVC. While direct exposure to this ultraviolet light is harmful for your skin or eyes, it can safely be utilized to clean air, water and some surfaces.

Lakeside Heating & Air uses this light in some of our solutions to improve air filtration in Chelan and Wenatchee homes.

How Ultraviolet Light is Used

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

This makes UVC light a potent replacement to chemical disinfection. Germicidal light is applied in a lot of disinfection uses, including medical laboratories and hospitals. It’s also used to clean drinking water and other liquids made in food processing.

It’s growing in popularity to purify air in residences in Chelan and Wenatchee. That’s because it can also wipe out typical indoor contaminants like mold, mildew and bacteria. This is an additional advantage for family members who suffer from seasonal allergies or asthma.

How to Use Germicidal UV Light in Your Home

We install a germicidal UV light inside your HVAC system’s ductwork. Since the light is put in the ductwork, it makes it compatible with many heating and cooling equipment. This also keeps its light safely housed while giving strong purification 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 residence. 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 can only clean the air in a single area. Portable air purifiers also can’t purify your ductwork or the interior of your HVAC system. A clean HVAC system is usually a more efficient one that could even run for an extended period of time. And, the majority of portable air purifiers have a bad reputation for creating ozone.

When considering buying a germicidal lamp for your house, it’s important to choose one that doesn’t make ozone. While ozone is great at eliminating odors and chemicals, it could also irritate your lungs and lead to other respiratory problems.
