How Do UVC Air Purifiers Work?

September 08, 2020

You likely are aware that the sun’s ultraviolet light (UV) causes painful sunburn. But were you aware that a different type of ultraviolet light can be installed to keep your house’s air clean?

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

There’s another type of UV light, referred to as UVC. While unprotected exposure to this ultraviolet light is harmful for your skin or eyes, it can safely be used to clean air, water and some surfaces.

Smyth Air Conditioning Inc uses this light in some of our systems to enhance air filtration in Lake Worth residences.

Applications for Ultraviolet Light

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 as they can’t multiply.

This makes UVC light a potent substitute to chemical disinfection. Germicidal light is applied in many disinfection applications, like medical laboratories and hospitals. It’s also applied to clean drinking water and other liquids made in food processing.

It’s becoming more popular to disinfect air in homes in Lake Worth. That’s because it can also wipe out typical indoor contaminants including mold, mildew and bacteria. This is an added advantage if someone in your household has seasonal allergies or asthma.

How to Use Germicidal UV Light in Your Residence

We install a germicidal UV light within your HVAC system’s ductwork. As the light is put within the ductwork, it makes it compatible with most heating and cooling units. This also keeps its rays safely confined while delivering great disinfection for your house’s air.

Filthy air is freshened in a two-step process, first moving through your air filter and then the UV light before circulating around your home. Even when your heat or air conditioning isn’t operating, these lights still function to keep your air, ductwork and home comfort system clean.

This whole-house option is greater than a portable air purifier, which can only clean the air in a lone room. Portable air purifiers also can’t freshen your ductwork or the interior of your HVAC equipment. A clean HVAC system is often a more efficient one that may even last for an extended period of time. And, some portable air purifiers have a bad reputation for creating ozone.

When thinking over buying a germicidal lamp for your house, it’s critical to get one that doesn’t make ozone. While ozone is great at wiping out odors and chemicals, it may also irritate your lungs and cause other respiratory symptoms.
