How Germicidal UV Light Works

September 08, 2020

You likely are aware 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 lets off two types of damaging UV rays, UVA and UVB. These harmful rays can lead to sunburn, skin cancer, wrinkles and other signs of premature aging.

There’s another type of UV light, referred to as UVC. While full exposure to this ultraviolet light is harmful for your skin or eyes, it can safely be utilized to clean air, water and various surfaces.

Street Heating and Cooling uses this light in a few of our products to enhance air filtration in Rapid City homes.

Applications for Ultraviolet Light

This distinct wavelength is called “germicidal” as it kills the DNA of bacteria and viruses. When pathogens pass through this light, they eventually die as they can’t spread.

This makes UVC light a mighty replacement to chemical disinfection. Germicidal light is applied in a lot of disinfection applications, such as medical laboratories and hospitals. It’s also used to purify drinking water and other liquids produced in food processing.

It’s growing in popularity to disinfect air in houses in Rapid City. That’s due to the fact it can also eradicate common indoor contaminants such as mold, mildew and bacteria. This is an extra benefit for loved ones who deal with seasonal allergies or asthma.

Installing Germicidal UV Light in Your House

We install a germicidal UV light within your HVAC system’s ductwork. Because the light is put inside the ductwork, it makes it compatible with the majority of heating and cooling units. This also keeps its rays securely contained while delivering strong disinfection for your residence’s air.

Contaminated air is cleaned 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 working, these lights still work to keep your air, ductwork and home comfort unit clean.

This whole-house option is greater than a portable air purifier, which is limited to cleaning the air in a single room. Portable air purifiers also can’t freshen your ductwork or the interior of your HVAC system. A clean HVAC system is typically a more efficient one that may even run for an extended period of time. And, many portable air purifiers are known for creating ozone.

When thinking about buying a germicidal lamp for your house, it’s critical to buy one that doesn’t produce ozone. While ozone is fantastic at wiping out odors and chemicals, it may also irritate your lungs and cause other respiratory troubles.
