How Does Germicidal UV Light Work?

September 08, 2020

You probably know that the sun’s ultraviolet light (UV) causes painful sunburn. But did you know that a different type of ultraviolet light can be useful for keeping your residence’s air clean?

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

There’s another kind of UV light, referred to as UVC. While direct exposure to this ultraviolet light is bad for your skin or eyes, it can safely be used to purify air, water and some surfaces.

Farnell Heating & Air Conditioning Inc uses this light in several of our products to better air filtration in Mobile houses.

Applications for Ultraviolet Light

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

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

It’s becoming more popular to freshen air in houses in Mobile. That’s since it can also eliminate frequent indoor contaminants such as mold, mildew and bacteria. This is an additional benefit for loved ones who deal with seasonal allergies or asthma.

Uses for Germicidal UV Light in Your House

We install a germicidal UV light in your HVAC system’s ductwork. Because the light is set in the ductwork, it makes it compatible with the majority of heating and cooling equipment. This also keeps its light safely contained while providing strong purification for your home’s air.

Filthy air is cleaned in a two-step process, first flowing through your air filter and then the UV light in advance of circulating throughout your residence. Even when your heat or air conditioning isn’t on, these lights still work to keep your air, ductwork and home comfort system clean.

This whole-house solution is superior to a portable air purifier, which is limited to cleaning the air in a lone room. Portable air purifiers also can’t purify your ductwork or the inside of your HVAC equipment. A clean HVAC system is often a more efficient one that can even last longer. And, the majority of portable air purifiers have a bad reputation for creating ozone.

When considering getting a germicidal lamp for your house, it’s essential to choose one that doesn’t make ozone. While ozone is good at wiping out odors and chemicals, it could also irritate your lungs and cause other respiratory issues.
