How Germicidal UV Light Works

September 08, 2020

Perhaps you realize that the sun’s ultraviolet light (UV) causes painful sunburn. But did you know that a different type of ultraviolet light can be used to keep your home’s air clean?

The sun lets off two types of harmful UV rays, UVA and UVB. These damaging rays can cause sunburn, skin cancer, wrinkles and other signs of premature aging.

There’s another variety of UV light, known as UVC. While unprotected exposure to this ultraviolet light is bad for your skin or eyes, it can safely be utilized to clean air, water and some surfaces.

Faust Air Conditioning and Heating uses this light in a few of our products to better air filtration in Wharton homes.

Applications for Ultraviolet Light

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

This makes UVC light a strong alternative to chemical disinfection. Germicidal light is applied in many disinfection uses, such as medical laboratories and hospitals. It’s also applied to clean drinking water and other liquids created in food processing.

It’s growing in popularity to disinfect air in homes in Wharton. That’s due to the fact it can also eradicate typical indoor contaminants like mold, mildew and bacteria. This is an extra benefit for family members who suffer from seasonal allergies or asthma.

How to Use Germicidal UV Light in Your House

We put a germicidal UV light within your HVAC system’s ductwork. As the light is put inside the ductwork, it makes it compatible with the majority of heating and cooling systems. This also keeps its light safely confined while giving strong cleaning for your home’s air.

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

This whole-house product is better than a portable air purifier, which is limited to cleaning the air in a lone space. Portable air purifiers also can’t clean your ductwork or the inside of your HVAC equipment. A clean HVAC system is usually a more efficient one that could even work for a longer life span. And, many portable air purifiers have a bad reputation for creating ozone.

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