Do UVC Air Purifiers Work?

September 08, 2020

Perhaps you realize that the sun’s ultraviolet light (UV) causes painful sunburn. But were you aware that a different type of ultraviolet light can be used to keep your home’s air clean?

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

There’s another variety of UV light, referred to as UVC. While direct exposure to this ultraviolet light isn’t good for your skin or eyes, it can safely be used to purify air, water and some surfaces.

US Air Heating and Cooling uses this light in some of our solutions to enhance air filtration in Rock Hill residences.

What is an Ultraviolet Light Used For?

This specific wavelength is called “germicidal” as it wipes out the DNA of bacteria and viruses. When pathogens travel through this light, they eventually cease to exist because they can’t reproduce.

This makes UVC light a mighty alternative to chemical disinfection. Germicidal light is applied in a lot of disinfection applications, including medical laboratories and hospitals. It’s also employed to sterilize drinking water and other liquids created in food processing.

It’s becoming a popular choice to freshen air in residences in Rock Hill. That’s because it can also eradicate common indoor contaminants including mold, mildew and bacteria. This is an additional advantage if someone in your household has seasonal allergies or asthma.

How to Use Germicidal UV Light in Your Home

We place a germicidal UV light within your HVAC system’s ductwork. Because the light is put inside the ductwork, it makes it compatible with many heating and cooling systems. This also keeps its light safely contained while giving great disinfection for your home’s air.

Filthy air is purified in a two-step process, first traveling through your air filter and then the UV light prior to moving across your residence. Even when your heat or air conditioning isn’t working, 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 a single room. Portable air purifiers also can’t purify your ductwork or the inside of your HVAC system. A clean HVAC system is usually a more efficient one that could even last for a longer life span. And, the majority of portable air purifiers are known for producing ozone.

When considering getting a germicidal lamp for your house, it’s essential to select one that doesn’t make ozone. While ozone is fantastic at eliminating odors and chemicals, it can also irritate your lungs and create other respiratory issues.
