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 were you aware that another kind of ultraviolet light can be installed to keep your residence’s air clean?

The sun gives off two types of damaging UV rays, UVA and UVB. These damaging rays can result in sunburn, skin cancer, wrinkles and other types of premature aging.

There’s another type of UV light, called UVC. While direct exposure to this ultraviolet light is bad for your skin or eyes, it can safely be used to clean air, water and certain surfaces.

Freed Heating & Air Conditioning uses this light in a few of our products to boost air filtration in Moline residences.

Applications for Ultraviolet Light

This precise wavelength is called “germicidal” since it destroys the DNA of bacteria and viruses. When pathogens move through this light, they eventually die as they can’t multiply.

This makes UVC light a strong substitute to chemical disinfection. Germicidal light is employed in a lot of disinfection uses, including medical laboratories and hospitals. It’s also used to clean drinking water and other liquids created in food processing.

It’s becoming a popular choice to disinfect air in residences in Moline. That’s because it can also eradicate common indoor contaminants including mold, mildew and bacteria. This is an added benefit for family members who suffer from seasonal allergies or asthma.

How to Use Germicidal UV Light in Your Home

We put a germicidal UV light in your HVAC system’s ductwork. As the light is installed within the ductwork, it makes it compatible with many heating and cooling systems. This also keeps its light safely contained while delivering powerful cleaning for your residence’s air.

Dirty air is cleaned in a two-step process, first flowing through your air filter and then the UV light before spreading throughout your residence. Even when your heat or air conditioning isn’t running, these lights still run to keep your air, ductwork and home comfort system clean.

This whole-house product is greater than a portable air purifier, which can only clean the air in one room. Portable air purifiers also can’t freshen your ductwork or the inside of your HVAC system. A clean HVAC system is often a more efficient one that may even work longer. And, many portable air purifiers are known for creating ozone.

When thinking over getting a germicidal lamp for your home, it’s important to get one that doesn’t create ozone. While ozone is fantastic at wiping out odors and chemicals, it may also irritate your lungs and create other respiratory issues.
