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 realize that another kind of ultraviolet light can be useful for keeping your house’s air clean?

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

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

B&D Air Conditioning uses this light in several of our solutions to better air filtration in Safford residences.

What is an Ultraviolet Light Used For?

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

This makes UVC light a mighty substitute to chemical disinfection. Germicidal light is applied in many disinfection procedures, including medical laboratories and hospitals. It’s also used to clean drinking water and other liquids created in food processing.

It’s becoming more popular to freshen air in houses in Safford. That’s because it can also eliminate common indoor contaminants including mold, mildew and bacteria. This is an additional perk for family members who suffer from seasonal allergies or asthma.

Uses for Germicidal UV Light in Your Home

We put a germicidal UV light in your HVAC system’s ductwork. Since the light is placed inside the ductwork, it makes it compatible with most heating and cooling units. This also keeps its beams safely housed while delivering great cleaning for your home’s air.

Dirty air is cleaned in a two-step process, first flowing through your air filter and then the UV light in advance of moving across your house. Even when your heat or air conditioning isn’t working, 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 a lone area. Portable air purifiers also can’t freshen your ductwork or the interior of your HVAC unit. A clean HVAC system is typically a more efficient one that may even operate longer. And, the majority of portable air purifiers have a bad reputation for making ozone.

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