Do UVC Air Purifiers Work?

September 08, 2020

You probably know 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 useful for keeping your house’s air clean?

The sun lets off two types of damaging UV rays, UVA and UVB. These damaging rays can cause sunburn, skin cancer, wrinkles and other signs of premature aging.

There’s another type of UV light, known as UVC. While direct exposure to this ultraviolet light isn’t good for your skin or eyes, it can safely be used to clean air, water and some surfaces.

Morgner Inc. Air Conditioning & Heating uses this light in a few of our solutions to boost air filtration in St. Louis homes.

How Ultraviolet Light is Used

This distinct wavelength is referred to as “germicidal” since it kills the DNA of bacteria and viruses. When pathogens travel through this light, they eventually cease to exist as they can’t multiply.

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

It’s becoming a popular choice to disinfect air in houses in St. Louis. That’s because it can also wipe out common indoor contaminants like mold, mildew and bacteria. This is an extra perk for family members who suffer from seasonal allergies or asthma.

Uses for Germicidal UV Light in Your Residence

We install a germicidal UV light within your HVAC system’s ductwork. Since the light is put within the ductwork, it makes it compatible with most heating and cooling systems. This also keeps its beams safely confined while providing strong purification for your residence’s air.

Contaminated air is freshened in a two-step process, first flowing through your air filter and then the UV light prior to circulating across your house. Even when your heat or air conditioning isn’t working, these lights still operate to keep your air, ductwork and home comfort unit clean.

This whole-house solution is greater than a portable air purifier, which can only clean 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 usually a more efficient one that may even last for a longer life span. And, some portable air purifiers are known for creating ozone.

When thinking over buying a germicidal lamp for your house, it’s critical to choose one that doesn’t create ozone. While ozone is fantastic at eliminating odors and chemicals, it may also irritate your lungs and cause other respiratory issues.
