How Do UVC Air Purifiers Work?

September 08, 2020

You probably know that the sun’s ultraviolet light (UV) results in 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 emits two types of damaging UV rays, UVA and UVB. These harmful rays can cause sunburn, skin cancer, wrinkles and other signs of premature aging.

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

Willco Air Conditioning, Refrigeration & Heating Inc. uses this light in some of our systems to better air filtration in Branchville houses.

Applications for Ultraviolet Light

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

This makes UVC light a powerful replacement to chemical disinfection. Germicidal light is applied in many disinfection applications, including medical laboratories and hospitals. It’s also used to sterilize drinking water and other liquids created in food processing.

It’s growing in popularity to freshen air in houses in Branchville. That’s since it can also wipe out common indoor contaminants such as mold, mildew and bacteria. This is an extra advantage for loved ones who deal with seasonal allergies or asthma.

How to Use Germicidal UV Light in Your Residence

We put a germicidal UV light within your HVAC system’s ductwork. As the light is placed inside the ductwork, it makes it compatible with most heating and cooling systems. This also keeps its rays carefully restricted while giving powerful purification for your house’s air.

Dirty air is freshened in a two-step process, first traveling through your air filter and then the UV light before circulating across your home. Even when your heat or air conditioning isn’t running, these lights still run to keep your air, ductwork and home comfort system clean.

This whole-house solution is better than a portable air purifier, which is limited to cleaning the air in a single area. Portable air purifiers also can’t purify your ductwork or the innerworkings of your HVAC unit. A clean HVAC system is typically a more efficient one that may even work for a longer life span. And, the majority of portable air purifiers are known for producing ozone.

When thinking about getting a germicidal lamp for your house, it’s important to get one that doesn’t make ozone. While ozone is great at eliminating odors and chemicals, it can also irritate your lungs and cause other respiratory issues.
