How Germicidal UV Light Works

September 08, 2020

You probably know that the sun’s ultraviolet light (UV) is to blame for your painful sunburn. But did you realize that another kind of ultraviolet light can be useful for keeping your residence’s air clean?

The sun emits two types of harmful UV rays, UVA and UVB. These harmful rays can result in sunburn, skin cancer, wrinkles and other kinds of premature aging.

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

Giordanos Heating and Air Conditioning uses this light in several of our solutions to improve air filtration in Derby homes.

How Ultraviolet Light is Used

This distinct wavelength is classified as “germicidal” since it eradicates the DNA of bacteria and viruses. When pathogens move through this light, they eventually perish as they can’t multiply.

This makes UVC light a powerful alternative to chemical disinfection. Germicidal light is used in many disinfection uses, like medical laboratories and hospitals. It’s also applied to purify drinking water and other liquids made in food processing.

It’s growing in popularity to disinfect air in houses in Derby. That’s because it can also wipe out frequent indoor contaminants including mold, mildew and bacteria. This is an additional benefit if someone in your household has seasonal allergies or asthma.

How to Use Germicidal UV Light in Your House

We place a germicidal UV light in your HVAC system’s ductwork. Because the light is set inside the ductwork, it makes it compatible with most heating and cooling units. This also keeps its beams carefully confined while delivering great purification for your house’s air.

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

This whole-house product is better than a portable air purifier, which can only clean the air in one room. Portable air purifiers also can’t purify your ductwork or the inside of your HVAC unit. A clean HVAC system is usually a more efficient one that could even operate for an extended period of time. And, many portable air purifiers are notorious for creating ozone.

When thinking over getting a germicidal lamp for your residence, it’s important to get one that doesn’t make ozone. While ozone is good at eradicating odors and chemicals, it could also irritate your lungs and lead to other respiratory issues.
