How Does Germicidal UV Light Work?

September 08, 2020

You likely are aware that the sun’s ultraviolet light (UV) causes painful sunburn. But did you know that another kind 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 kinds of premature aging.

There’s another kind 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 purify air, water and some surfaces.

Clean Air HVAC uses this light in a few of our solutions to better air filtration in Pacheco residences.

Applications for Ultraviolet Light

This distinct wavelength is called “germicidal” since it eradicates the DNA of bacteria and viruses. When pathogens travel through this light, they eventually cease to exist because they can’t spread.

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

It’s growing in popularity to disinfect air in residences in Pacheco. That’s due to the fact it can also eliminate typical indoor contaminants such as mold, mildew and bacteria. This is an extra advantage for loved ones who deal with seasonal allergies or asthma.

How to Use Germicidal UV Light in Your Home

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

Contaminated air is cleaned in a two-step process, first flowing through your air filter and then the UV light in advance of spreading around your home. Even when your heat or air conditioning isn’t running, these lights still run to keep your air, ductwork and home comfort system clean.

This whole-house solution is greater than a portable air purifier, which is limited to cleaning the air in one space. Portable air purifiers also can’t clean your ductwork or the interior of your HVAC system. A clean HVAC system is typically a more efficient one that may even run for a longer life span. And, some portable air purifiers have a bad reputation for making ozone.

When thinking about adding a germicidal lamp to your house, it’s critical to look for one that doesn’t create ozone. While ozone is fantastic at eradicating odors and chemicals, it might also irritate your lungs and lead to other respiratory problems.
