How Does Germicidal UV Light Work?

September 08, 2020

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

The sun lets off two types of damaging UV rays, UVA and UVB. These dangerous rays can result in sunburn, skin cancer, wrinkles and other types 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.

Tokay Heating and Air Conditioning uses this light in a few of our products to boost air filtration in Lodi houses.

What is an Ultraviolet Light Used For?

This precise wavelength is called “germicidal” because it kills the DNA of bacteria and viruses. When pathogens pass through this light, they eventually perish as they can’t multiply.

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

It’s becoming more popular to disinfect air in residences in Lodi. That’s due to the fact it can also wipe out common indoor contaminants such as mold, mildew and bacteria. This is an extra benefit for family members who suffer from seasonal allergies or asthma.

Uses for Germicidal UV Light in Your House

We put a germicidal UV light within your HVAC system’s ductwork. Because the light is set within the ductwork, it makes it compatible with many heating and cooling equipment. This also keeps its beams securely restricted while giving powerful disinfection for your house’s air.

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

This whole-house option is better than a portable air purifier, which can only clean the air in one room. Portable air purifiers also can’t purify your ductwork or the interior of your HVAC equipment. A clean HVAC system is often a more efficient one that can even last for an extended period of time. And, many portable air purifiers have a bad reputation for making ozone.

When thinking about getting a germicidal lamp for your home, it’s important to buy one that doesn’t make ozone. While ozone is good at eliminating odors and chemicals, it could also irritate your lungs and lead to other respiratory issues.
