How Germicidal UV Light Works

September 08, 2020

Perhaps you realize that the sun’s ultraviolet light (UV) causes painful sunburn. But did you realize that another variety of ultraviolet light can be useful for keeping your house’s air clean?

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

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

H&C Heating and Cooling uses this light in a few of our products to boost air filtration in Laurel homes.

What is an Ultraviolet Light Used For?

This precise wavelength is referred to as “germicidal” as it wipes out the DNA of bacteria and viruses. When pathogens pass through this light, they eventually perish because they can’t reproduce.

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

It’s becoming more popular to purify air in residences in Laurel. That’s because it can also eliminate frequent indoor contaminants such as mold, mildew and bacteria. This is an extra perk for loved ones who deal with seasonal allergies or asthma.

Uses for Germicidal UV Light in Your Home

We install a germicidal UV light inside your HVAC system’s ductwork. Since the light is put within the ductwork, it makes it compatible with most heating and cooling units. This also keeps its rays carefully housed while giving powerful cleaning for your house’s air.

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

This whole-house solution is superior to a portable air purifier, which is limited to cleaning the air in a lone area. Portable air purifiers also can’t freshen your ductwork or the innerworkings of your HVAC unit. A clean HVAC system is typically a more efficient one that can even run for an extended period of time. And, some portable air purifiers are notorious for making ozone.

When thinking about adding a germicidal lamp to your home, it’s important to get one that doesn’t make ozone. While ozone is good at eliminating odors and chemicals, it might also irritate your lungs and cause other respiratory symptoms.
