How Germicidal UV Light Works

September 08, 2020

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

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

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

Mayeuxs AC & Heating uses this light in some of our solutions to boost air filtration in Norco and St. Charles Parish houses.

Applications for Ultraviolet Light

This distinct wavelength is called “germicidal” as it eradicates the DNA of bacteria and viruses. When pathogens travel through this light, they eventually die since they can’t reproduce.

This makes UVC light a strong replacement to chemical disinfection. Germicidal light is employed in lots of disinfection applications, including medical laboratories and hospitals. It’s also employed to purify drinking water and other liquids made in food processing.

It’s growing in popularity to freshen air in residences in Norco and St. Charles Parish. That’s since it can also wipe out frequent indoor contaminants like mold, mildew and bacteria. This is an extra perk if someone in your household has seasonal allergies or asthma.

Using Germicidal UV Light in Your House

We put a germicidal UV light inside your HVAC system’s ductwork. Since the light is installed within the ductwork, it makes it compatible with the majority of heating and cooling units. This also keeps its beams securely contained while delivering strong disinfection for your home’s air.

Filthy air is purified in a two-step process, first traveling through your air filter and then the UV light prior to moving around your house. Even when your heat or air conditioning isn’t operating, these lights still run to keep your air, ductwork and home comfort unit clean.

This whole-house solution is greater than a portable air purifier, which is limited to cleaning the air in a lone space. Portable air purifiers also can’t purify your ductwork or the innerworkings of your HVAC unit. A clean HVAC system is often a more efficient one that could even run for a longer life span. And, many portable air purifiers have a bad reputation for producing ozone.

When thinking about adding a germicidal lamp to your home, it’s critical to select one that doesn’t make ozone. While ozone is great at getting rid of odors and chemicals, it can also irritate your lungs and lead to other respiratory troubles.
