How Germicidal UV Light Works

September 08, 2020

You probably know 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 gives off two types of dangerous UV rays, UVA and UVB. These harmful rays can cause sunburn, skin cancer, wrinkles and other kinds of premature aging.

There’s another kind of UV light, known as UVC. While unprotected exposure to this ultraviolet light is harmful for your skin or eyes, it can safely be applied to disinfect air, water and various surfaces.

Rescue Heating & Air uses this light in several of our systems to boost air filtration in Alice houses.

Applications for Ultraviolet Light

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

This makes UVC light a potent alternative to chemical disinfection. Germicidal light is applied in a lot of disinfection procedures, such as 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 houses in Alice. That’s due to the fact it can also eradicate common indoor contaminants like mold, mildew and bacteria. This is an additional benefit if someone in your household has seasonal allergies or asthma.

Having Germicidal UV Light in Your Residence

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

Dirty air is purified in a two-step process, first flowing through your air filter and then the UV light prior to 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 system clean.

This whole-house option is better than a portable air purifier, which is restricted to cleaning the air in one area. Portable air purifiers also can’t purify your ductwork or the inside of your HVAC equipment. A clean HVAC system is typically a more efficient one that could even run longer. And, the majority of portable air purifiers are notorious for producing ozone.

When thinking over getting a germicidal lamp for your house, it’s critical to select one that doesn’t produce ozone. While ozone is great at wiping out odors and chemicals, it might also irritate your lungs and create other respiratory troubles.
