How Does Germicidal UV Light Work?

September 08, 2020

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

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

There’s another variety 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 applied to disinfect air, water and some surfaces.

American HVAC Inc uses this light in some of our solutions to enhance air filtration in Sacramento houses.

Applications for Ultraviolet Light

This distinct wavelength is classified as “germicidal” since it destroys the DNA of bacteria and viruses. When pathogens pass through this light, they eventually die since they can’t spread.

This makes UVC light a strong replacement to chemical disinfection. Germicidal light is used in a lot of disinfection procedures, such as medical laboratories and hospitals. It’s also employed to sterilize drinking water and other liquids made in food processing.

It’s becoming a popular choice to freshen air in houses in Sacramento. That’s due to the fact it can also eradicate typical indoor contaminants like mold, mildew and bacteria. This is an additional advantage for loved ones who deal with seasonal allergies or asthma.

Installing Germicidal UV Light in Your Home

We install a germicidal UV light inside your HVAC system’s ductwork. Because the light is placed inside the ductwork, it makes it compatible with most heating and cooling equipment. This also keeps its light carefully contained while giving strong cleaning for your residence’s air.

Dirty air is cleaned in a two-step process, first traveling through your air filter and then the UV light before circulating around your residence. Even when your heat or air conditioning isn’t operating, these lights still operate to keep your air, ductwork and home comfort unit clean.

This whole-house option is superior to a portable air purifier, which is limited to cleaning the air in a lone space. Portable air purifiers also can’t purify your ductwork or the inside of your HVAC unit. A clean HVAC system is typically a more efficient one that could even work for an extended period of time. And, some portable air purifiers have a bad reputation for creating ozone.

When thinking over adding a germicidal lamp to your residence, it’s critical to select one that doesn’t create ozone. While ozone is great at getting rid of odors and chemicals, it could also irritate your lungs and cause other respiratory problems.
