How Germicidal UV Light Works

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 installed to keep your house’s air clean?

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

There’s another concentration of UV light, known as UVC. While unprotected exposure to this ultraviolet light isn’t good for your skin or eyes, it can safely be utilized to disinfect air, water and certain surfaces.

Carefree Heating and Cooling, LLC uses this light in several of our systems to improve air filtration in Hamilton residences.

Applications for Ultraviolet Light

This precise wavelength is called “germicidal” since it wipes out the DNA of bacteria and viruses. When pathogens move through this light, they eventually perish as they can’t spread.

This makes UVC light a powerful alternative to chemical disinfection. Germicidal light is used in a lot of disinfection applications, such as 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 purify air in homes in Hamilton. That’s since it can also eradicate frequent indoor contaminants such as 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 House

We install a germicidal UV light inside your HVAC system’s ductwork. Since the light is put in the ductwork, it makes it compatible with most heating and cooling units. This also keeps its light safely contained while giving strong disinfection for your residence’s air.

Dirty air is freshened in a two-step process, first traveling through your air filter and then the UV light in advance of spreading around your house. Even when your heat or air conditioning isn’t operating, 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 a lone space. Portable air purifiers also can’t clean your ductwork or the interior of your HVAC equipment. A clean HVAC system is usually a more efficient one that could even last for a longer life span. And, many portable air purifiers have a bad reputation for making ozone.

When thinking about getting a germicidal lamp for your house, it’s essential to choose one that doesn’t create ozone. While ozone is great at eliminating odors and chemicals, it can also irritate your lungs and lead to other respiratory symptoms.
