How Does Germicidal UV Light Work?

September 08, 2020

Perhaps you realize that the sun’s ultraviolet light (UV) results in painful sunburn. But did you realize that a different type of ultraviolet light can be installed to keep your home’s air clean?

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

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

Franklin's Heating & Air Conditioning, Inc uses this light in several of our products to boost air filtration in Oxford houses.

Applications for Ultraviolet Light

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

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

It’s growing in popularity to purify air in residences in Oxford. That’s because it can also wipe out typical indoor contaminants such as mold, mildew and bacteria. This is an added perk for loved ones who deal with seasonal allergies or asthma.

Uses for Germicidal UV Light in Your Home

We install a germicidal UV light in your HVAC system’s ductwork. As the light is put in the ductwork, it makes it compatible with the majority of heating and cooling equipment. This also keeps its light safely housed while giving powerful cleaning for your house’s air.

Filthy air is purified in a two-step process, first flowing through your air filter and then the UV light prior to moving around your home. Even when your heat or air conditioning isn’t running, these lights still function to keep your air, ductwork and home comfort system clean.

This whole-house product is better than a portable air purifier, which is restricted to cleaning the air in one space. Portable air purifiers also can’t purify your ductwork or the interior of your HVAC equipment. A clean HVAC system is usually a more efficient one that can even run for a longer life span. And, the majority of portable air purifiers are notorious for creating ozone.

When considering adding a germicidal lamp to your home, it’s essential to choose one that doesn’t produce ozone. While ozone is good at eliminating odors and chemicals, it might also irritate your lungs and lead to other respiratory symptoms.
