How Does Germicidal UV Light Work?

September 08, 2020

Perhaps you realize that the sun’s ultraviolet light (UV) results in painful sunburn. But did you realize that a different type of ultraviolet light can be installed to keep your house’s air clean?

The sun lets off two types of damaging UV rays, UVA and UVB. These dangerous 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 unprotected exposure to this ultraviolet light is harmful for your skin or eyes, it can safely be applied to clean air, water and certain surfaces.

Cool Air Solutions uses this light in a few of our products to enhance air filtration in Murrieta houses.

How Ultraviolet Light is Used

This specific wavelength is classified as “germicidal” because it kills the DNA of bacteria and viruses. When pathogens pass through this light, they eventually perish since they can’t reproduce.

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

It’s becoming more popular to freshen air in homes in Murrieta. That’s due to the fact it can also eliminate frequent indoor contaminants including mold, mildew and bacteria. This is an added benefit if someone in your household has seasonal allergies or asthma.

Uses for Germicidal UV Light in Your Residence

We place a germicidal UV light inside your HVAC system’s ductwork. As the light is installed inside the ductwork, it makes it compatible with many heating and cooling equipment. This also keeps its light securely restricted while giving great disinfection for your home’s air.

Contaminated air is purified in a two-step process, first moving through your air filter and then the UV light in advance of spreading across your house. Even when your heat or air conditioning isn’t running, these lights still work to keep your air, ductwork and home comfort equipment clean.

This whole-house option is superior to a portable air purifier, which is limited to cleaning the air in a lone space. Portable air purifiers also can’t freshen your ductwork or the inside of your HVAC system. A clean HVAC system is usually a more efficient one that may even run longer. And, many portable air purifiers are notorious for creating ozone.

When thinking about buying a germicidal lamp for your home, it’s essential to get one that doesn’t produce ozone. While ozone is good at getting rid of odors and chemicals, it may also irritate your lungs and cause other respiratory troubles.
