How Does Germicidal UV Light Work?

September 08, 2020

Perhaps you realize that the sun’s ultraviolet light (UV) causes painful sunburn. But were you aware that another variety of ultraviolet light can be installed to keep your home’s air clean?

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

There’s another type of UV light, called UVC. While unprotected exposure to this ultraviolet light is bad for your skin or eyes, it can safely be utilized to clean air, water and certain surfaces.

Evenaire Heating & Air Conditioning uses this light in a few of our systems to improve air filtration in Pflugerville homes.

Applications for Ultraviolet Light

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

This makes UVC light a potent substitute to chemical disinfection. Germicidal light is employed in a lot of disinfection applications, such as medical laboratories and hospitals. It’s also applied to purify drinking water and other liquids made in food processing.

It’s growing in popularity to disinfect air in residences in Pflugerville. That’s because it can also eliminate frequent indoor contaminants including mold, mildew and bacteria. This is an additional advantage for family members who suffer from seasonal allergies or asthma.

How to Use Germicidal UV Light in Your House

We install a germicidal UV light in your HVAC system’s ductwork. Since the light is placed inside the ductwork, it makes it compatible with many heating and cooling equipment. This also keeps its beams carefully contained while delivering great cleaning for your house’s air.

Dirty air is freshened in a two-step process, first traveling through your air filter and then the UV light before circulating across your home. Even when your heat or air conditioning isn’t working, these lights still operate 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 area. Portable air purifiers also can’t clean your ductwork or the interior of your HVAC unit. A clean HVAC system is often a more efficient one that may even work for an extended period of time. And, the majority of portable air purifiers are notorious for producing ozone.

When thinking over adding a germicidal lamp to your residence, it’s important to get one that doesn’t produce ozone. While ozone is great at wiping out odors and chemicals, it could also irritate your lungs and cause other respiratory issues.
