How Does Germicidal UV Light Work?

September 08, 2020

You probably know that the sun’s ultraviolet light (UV) causes painful sunburn. But were you aware that another kind of ultraviolet light can be used to keep your residence’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, referred to as UVC. While unprotected exposure to this ultraviolet light isn’t good for your skin or eyes, it can safely be used to disinfect air, water and various surfaces.

Bishop Heating & Air Conditioning uses this light in a few of our products to improve air filtration in Bishop houses.

Applications for Ultraviolet Light

This specific wavelength is classified as “germicidal” since it wipes out the DNA of bacteria and viruses. When pathogens travel through this light, they eventually die since they can’t multiply.

This makes UVC light a potent substitute to chemical disinfection. Germicidal light is used in lots of disinfection procedures, such as medical laboratories and hospitals. It’s also employed to clean drinking water and other liquids made in food processing.

It’s growing in popularity to purify air in houses in Bishop. That’s since it can also wipe out common indoor contaminants including mold, mildew and bacteria. This is an extra benefit for loved ones who deal with seasonal allergies or asthma.

How to Use Germicidal UV Light in Your Home

We put a germicidal UV light in your HVAC system’s ductwork. Since the light is installed within the ductwork, it makes it compatible with most heating and cooling equipment. This also keeps its rays safely housed while giving strong cleaning for your home’s air.

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

This whole-house solution is better than a portable air purifier, which can only clean the air in a lone room. Portable air purifiers also can’t purify your ductwork or the inside of your HVAC system. A clean HVAC system is often a more efficient one that could even work for a longer life span. And, some portable air purifiers have a bad reputation for making ozone.

When thinking about buying a germicidal lamp for your residence, it’s critical to look for one that doesn’t make ozone. While ozone is good at getting rid of odors and chemicals, it can also irritate your lungs and cause other respiratory symptoms.
