How Germicidal UV Light Works

September 08, 2020

You probably know that the sun’s ultraviolet light (UV) results in painful sunburn. But were you aware that a different type of ultraviolet light can be useful for keeping your house’s air clean?

The sun lets 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 type of UV light, called UVC. While full exposure to this ultraviolet light isn’t good for your skin or eyes, it can safely be used to purify air, water and some surfaces.

A&M Heating & Cooling LLC uses this light in several of our products to boost air filtration in Tucson homes.

How Ultraviolet Light is Used

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

This makes UVC light a mighty replacement to chemical disinfection. Germicidal light is used in a lot of disinfection uses, such as medical laboratories and hospitals. It’s also used to purify drinking water and other liquids made in food processing.

It’s growing in popularity to purify air in residences in Tucson. That’s due to the fact it can also eliminate common indoor contaminants like mold, mildew and bacteria. This is an extra advantage for loved ones who deal with seasonal allergies or asthma.

Uses for Germicidal UV Light in Your Residence

We put a germicidal UV light inside your HVAC system’s ductwork. Because the light is put in the ductwork, it makes it compatible with most heating and cooling equipment. This also keeps its rays securely restricted while delivering great cleaning for your house’s air.

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

This whole-house option is greater than a portable air purifier, which can only clean the air in one area. Portable air purifiers also can’t freshen your ductwork or the inside of your HVAC unit. A clean HVAC system is typically a more efficient one that may even work for an extended period of time. And, the majority of portable air purifiers have a bad reputation for creating ozone.

When considering getting a germicidal lamp for your home, it’s critical to get one that doesn’t make ozone. While ozone is great at eradicating odors and chemicals, it can also irritate your lungs and cause other respiratory troubles.
