How Do UVC Air Purifiers Work?

September 08, 2020

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

The sun emits two types of harmful UV rays, UVA and UVB. These dangerous rays can cause sunburn, skin cancer, wrinkles and other kinds of premature aging.

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

Davis Heating & Air Conditioning uses this light in some of our systems to enhance air filtration in Rocky Mount residences.

How Ultraviolet Light is Used

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

This makes UVC light a strong substitute to chemical disinfection. Germicidal light is applied in a lot of disinfection applications, like medical laboratories and hospitals. It’s also used to sterilize drinking water and other liquids produced in food processing.

It’s growing in popularity to purify air in houses in Rocky Mount. That’s due to the fact it can also wipe out typical indoor contaminants such as mold, mildew and bacteria. This is an additional benefit if someone in your household has seasonal allergies or asthma.

Uses for Germicidal UV Light in Your Home

We place a germicidal UV light within your HVAC system’s ductwork. Because the light is installed within the ductwork, it makes it compatible with many heating and cooling systems. This also keeps its rays carefully restricted while giving strong purification for your house’s air.

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

This whole-house solution is greater than a portable air purifier, which is limited to cleaning the air in one area. Portable air purifiers also can’t freshen your ductwork or the interior of your HVAC system. A clean HVAC system is usually a more efficient one that can even operate for an extended period of time. And, many portable air purifiers are notorious for producing ozone.

When thinking over buying a germicidal lamp for your residence, it’s critical to get one that doesn’t make ozone. While ozone is great at getting rid of odors and chemicals, it might also irritate your lungs and lead to other respiratory troubles.
