How Does Germicidal UV Light Work?

September 08, 2020

You probably know that the sun’s ultraviolet light (UV) is to blame for your painful sunburn. But did you realize that another variety of ultraviolet light can be installed to keep your residence’s air clean?

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

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

American HVAC Inc uses this light in a few of our solutions to improve air filtration in San Jose homes.

Applications for Ultraviolet Light

This precise wavelength is called “germicidal” because it destroys the DNA of bacteria and viruses. When pathogens travel through this light, they eventually die since they can’t spread.

This makes UVC light a strong substitute to chemical disinfection. Germicidal light is used in many disinfection procedures, like medical laboratories and hospitals. It’s also used to sterilize drinking water and other liquids produced in food processing.

It’s becoming more popular to freshen air in residences in San Jose. That’s since it can also eradicate typical indoor contaminants such as mold, mildew and bacteria. This is an additional advantage for family members who suffer from seasonal allergies or asthma.

Using Germicidal UV Light in Your Home

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 the majority of heating and cooling equipment. This also keeps its beams safely restricted 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 prior to spreading throughout your residence. Even when your heat or air conditioning isn’t on, these lights still run to keep your air, ductwork and home comfort unit clean.

This whole-house product is superior to a portable air purifier, which is restricted to cleaning the air in a single space. Portable air purifiers also can’t freshen your ductwork or the inside of your HVAC equipment. A clean HVAC system is often a more efficient one that could even work longer. And, the majority of portable air purifiers are notorious for creating ozone.

When thinking over buying a germicidal lamp for your residence, it’s essential to select one that doesn’t create ozone. While ozone is great at wiping out odors and chemicals, it can also irritate your lungs and cause other respiratory issues.
