How Does Germicidal UV Light Work?

September 08, 2020

You probably know that the sun’s ultraviolet light (UV) is to blame for your painful sunburn. But did you know that a different type of ultraviolet light can be installed to keep your home’s air clean?

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

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

SchagrinGAS Company uses this light in some of our systems to better air filtration in Middletown houses.

What is an Ultraviolet Light Used For?

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

This makes UVC light a strong replacement to chemical disinfection. Germicidal light is applied in lots of disinfection uses, like medical laboratories and hospitals. It’s also used to clean drinking water and other liquids produced in food processing.

It’s becoming more popular to freshen air in residences in Middletown. That’s since it can also eradicate frequent indoor contaminants such as mold, mildew and bacteria. This is an extra perk if someone in your household has seasonal allergies or asthma.

Uses for Germicidal UV Light in Your Home

We place a germicidal UV light in your HVAC system’s ductwork. Since the light is set inside the ductwork, it makes it compatible with many heating and cooling equipment. This also keeps its rays safely confined while delivering powerful purification for your home’s air.

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

This whole-house solution is greater than a portable air purifier, which is limited to cleaning the air in one area. Portable air purifiers also can’t clean your ductwork or the inside of your HVAC unit. A clean HVAC system is usually a more efficient one that can even last for an extended period of time. And, some portable air purifiers have a bad reputation for producing ozone.

When thinking over getting a germicidal lamp for your residence, it’s critical to choose one that doesn’t make ozone. While ozone is fantastic at eliminating odors and chemicals, it can also irritate your lungs and cause other respiratory troubles.
