How Do UVC Air Purifiers Work?

September 08, 2020

Perhaps you realize that the sun’s ultraviolet light (UV) is to blame for your painful sunburn. But were you aware that a different type of ultraviolet light can be useful for keeping your home’s air clean?

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

There’s another type of UV light, called UVC. While direct exposure to this ultraviolet light is harmful for your skin or eyes, it can safely be used to disinfect air, water and various surfaces.

Watts Electric & A/C Inc uses this light in a few of our systems to better air filtration in Columbia houses.

What is an Ultraviolet Light Used For?

This precise wavelength is referred to as “germicidal” because it kills the DNA of bacteria and viruses. When pathogens move 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 employed in a lot of disinfection procedures, like medical laboratories and hospitals. It’s also employed to purify drinking water and other liquids made in food processing.

It’s growing in popularity to freshen air in houses in Columbia. That’s due to the fact it can also wipe out common indoor contaminants like mold, mildew and bacteria. This is an added benefit for loved ones who deal with seasonal allergies or asthma.

How to Use Germicidal UV Light in Your House

We put a germicidal UV light in your HVAC system’s ductwork. As the light is set within the ductwork, it makes it compatible with many heating and cooling units. This also keeps its rays safely housed while giving strong purification 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 prior to spreading throughout your house. Even when your heat or air conditioning isn’t working, these lights still work to keep your air, ductwork and home comfort unit clean.

This whole-house solution is greater than a portable air purifier, which is limited to cleaning the air in a single room. Portable air purifiers also can’t clean your ductwork or the interior of your HVAC system. A clean HVAC system is often a more efficient one that can even last longer. And, many portable air purifiers are known for making ozone.

When considering getting a germicidal lamp for your house, it’s critical to buy one that doesn’t create ozone. While ozone is good at eliminating odors and chemicals, it could also irritate your lungs and cause other respiratory troubles.
