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 useful for keeping your residence’s air clean?

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

There’s another type 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 disinfect air, water and various surfaces.

Brooks Heating and Air Conditioning uses this light in some of our products to boost air filtration in Bossier City residences.

How Ultraviolet Light is Used

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

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

It’s becoming a popular choice to disinfect air in houses in Bossier City. That’s since it can also eliminate typical indoor contaminants including mold, mildew and bacteria. This is an extra perk for loved ones who deal with seasonal allergies or asthma.

How to Use Germicidal UV Light in Your Residence

We place a germicidal UV light within your HVAC system’s ductwork. Because the light is installed inside the ductwork, it makes it compatible with most heating and cooling units. This also keeps its rays safely housed while providing great disinfection for your home’s air.

Contaminated air is cleaned in a two-step process, first flowing through your air filter and then the UV light in advance of circulating around your residence. Even when your heat or air conditioning isn’t running, these lights still function to keep your air, ductwork and home comfort equipment clean.

This whole-house option is greater than a portable air purifier, which can only clean the air in one space. Portable air purifiers also can’t purify your ductwork or the interior of your HVAC unit. A clean HVAC system is typically a more efficient one that could even last for an extended period of time. And, many portable air purifiers are notorious for producing ozone.

When thinking about getting a germicidal lamp for your home, it’s essential to look for one that doesn’t produce ozone. While ozone is fantastic at eradicating odors and chemicals, it can also irritate your lungs and lead to other respiratory problems.
