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 realize that another kind of ultraviolet light can be used to keep your residence’s air clean?

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

There’s another kind of UV light, known as UVC. While full exposure to this ultraviolet light is bad for your skin or eyes, it can safely be applied to disinfect air, water and certain surfaces.

Wallpe Heating & Cooling uses this light in several of our systems to better air filtration in Greensburg residences.

Applications for Ultraviolet Light

This specific wavelength is referred to as “germicidal” since it eradicates the DNA of bacteria and viruses. When pathogens travel through this light, they eventually die because they can’t spread.

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

It’s becoming a popular choice to freshen air in houses in Greensburg. That’s due to the fact it can also eradicate frequent indoor contaminants like mold, mildew and bacteria. This is an additional perk if someone in your household has seasonal allergies or asthma.

Having Germicidal UV Light in Your Home

We put a germicidal UV light in your HVAC system’s ductwork. As the light is installed within the ductwork, it makes it compatible with many heating and cooling systems. This also keeps its light carefully housed while providing great cleaning for your house’s air.

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

This whole-house solution is superior to a portable air purifier, which can only clean the air in a lone room. Portable air purifiers also can’t freshen 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, some portable air purifiers are known for producing ozone.

When considering adding a germicidal lamp to your house, it’s essential to choose one that doesn’t make ozone. While ozone is fantastic at getting rid of odors and chemicals, it can also irritate your lungs and lead to other respiratory problems.
