How Does Germicidal UV Light Work?

September 08, 2020

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

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

There’s another concentration of UV light, known as UVC. While unprotected exposure to this ultraviolet light isn’t good for your skin or eyes, it can safely be utilized to disinfect air, water and various surfaces.

Osceola Air, LLC uses this light in some of our systems to improve air filtration in St. Cloud houses.

Applications for Ultraviolet Light

This distinct wavelength is classified as “germicidal” because it destroys the DNA of bacteria and viruses. When pathogens pass through this light, they eventually cease to exist as they can’t multiply.

This makes UVC light a powerful replacement to chemical disinfection. Germicidal light is employed in many disinfection procedures, 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 purify air in homes in St. Cloud. That’s due to the fact it can also wipe out common indoor contaminants such as mold, mildew and bacteria. This is an added advantage if someone in your household has seasonal allergies or asthma.

Having Germicidal UV Light in Your Residence

We put a germicidal UV light within your HVAC system’s ductwork. Since the light is put in the ductwork, it makes it compatible with the majority of heating and cooling equipment. This also keeps its rays safely restricted while delivering great disinfection for your residence’s air.

Dirty air is freshened in a two-step process, first moving through your air filter and then the UV light prior to flowing around your home. Even when your heat or air conditioning isn’t on, these lights still operate to keep your air, ductwork and home comfort equipment clean.

This whole-house product is greater than a portable air purifier, which is limited to cleaning the air in one area. Portable air purifiers also can’t purify your ductwork or the inside of your HVAC unit. A clean HVAC system is typically a more efficient one that may even last for an extended period of time. And, some portable air purifiers are known for producing ozone.

When thinking about buying a germicidal lamp for your house, it’s essential to look for one that doesn’t make ozone. While ozone is great at getting rid of odors and chemicals, it might also irritate your lungs and cause other respiratory troubles.
