How Does Germicidal UV Light Work?

September 08, 2020

You likely are aware that the sun’s ultraviolet light (UV) is to blame for your painful sunburn. But did you realize that another kind of ultraviolet light can be used to keep your home’s air clean?

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

There’s another kind of UV light, referred to as UVC. While full exposure to this ultraviolet light isn’t good for your skin or eyes, it can safely be utilized to purify air, water and some surfaces.

Home Comfort Heating & Air uses this light in a few of our systems to improve air filtration in Elk River homes.

How Ultraviolet Light is Used

This specific wavelength is called “germicidal” because it wipes out the DNA of bacteria and viruses. When pathogens travel through this light, they eventually cease to exist because they can’t multiply.

This makes UVC light a mighty substitute to chemical disinfection. Germicidal light is used in lots of disinfection procedures, including medical laboratories and hospitals. It’s also employed to sterilize drinking water and other liquids produced in food processing.

It’s growing in popularity to freshen air in homes in Elk River. That’s since it can also wipe out typical indoor contaminants such as mold, mildew and bacteria. This is an extra perk for family members who suffer from seasonal allergies or asthma.

How to Use Germicidal UV Light in Your Home

We place a germicidal UV light in 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 securely housed while providing great disinfection for your residence’s air.

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

This whole-house product is superior to a portable air purifier, which can only clean the air in one room. Portable air purifiers also can’t freshen your ductwork or the inside of your HVAC unit. A clean HVAC system is often a more efficient one that may even operate for a longer life span. And, many portable air purifiers are notorious for creating ozone.

When thinking over buying a germicidal lamp for your house, it’s important to buy one that doesn’t create ozone. While ozone is fantastic at eradicating odors and chemicals, it might also irritate your lungs and create other respiratory troubles.
