How Does Germicidal UV Light Work?

You probably know that the sun’s ultraviolet light (UV) results in painful sunburn. But did you realize that another variety of ultraviolet light can be used to keep your house’s air clean?

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

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

PWA Heating & Cooling Inc uses this light in some of our products to boost air filtration in Plainfield houses.

How Ultraviolet Light is Used

This distinct wavelength is referred to as “germicidal” as it kills the DNA of bacteria and viruses. When pathogens move through this light, they eventually perish since they can’t spread.

This makes UVC light a strong replacement to chemical disinfection. Germicidal light is applied in many disinfection uses, like medical laboratories and hospitals. It’s also employed to sterilize drinking water and other liquids made in food processing.

It’s becoming more popular to disinfect air in residences in Plainfield. That’s since it can also wipe out common indoor contaminants including mold, mildew and bacteria. This is an additional advantage for family members who suffer from seasonal allergies or asthma.

Having Germicidal UV Light in Your Home

We place a germicidal UV light in your HVAC system’s ductwork. Since the light is set in the ductwork, it makes it compatible with most heating and cooling units. This also keeps its light securely confined while providing powerful disinfection for your house’s air.

Filthy air is freshened in a two-step process, first moving through your air filter and then the UV light before circulating throughout your residence. 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 solution is better than a portable air purifier, which is restricted to cleaning the air in one room. Portable air purifiers also can’t clean your ductwork or the innerworkings of your HVAC system. A clean HVAC system is often a more efficient one that can even last longer. And, the majority of portable air purifiers have a bad reputation for producing ozone.

When thinking over buying a germicidal lamp for your house, it’s important to get one that doesn’t make ozone. While ozone is great at wiping out odors and chemicals, it could also irritate your lungs and create other respiratory issues.
