Is UV Light for My AC or Furnace Worth It?

September 08, 2020

Perhaps you realize that the sun’s ultraviolet light (UV) causes painful sunburn. But were you aware that a different type of ultraviolet light can be used to keep your home’s air clean?

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

There’s another kind of UV light, referred to as UVC. While unprotected exposure to this ultraviolet light isn’t good for your skin or eyes, it can safely be applied to disinfect air, water and certain surfaces.

Farnell Mechanical, Inc. uses this light in some of our products to boost air filtration in Opelika homes.

What is an Ultraviolet Light Used For?

This specific wavelength is called “germicidal” as it eradicates 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 potent alternative to chemical disinfection. Germicidal light is employed in lots of disinfection uses, including medical laboratories and hospitals. It’s also employed to purify drinking water and other liquids produced in food processing.

It’s becoming more popular to freshen air in houses in Opelika. That’s since it can also eradicate frequent indoor contaminants such as mold, mildew and bacteria. This is an added advantage if someone in your household has seasonal allergies or asthma.

Uses for Germicidal UV Light in Your Home

We put a germicidal UV light inside your HVAC system’s ductwork. Since the light is put inside the ductwork, it makes it compatible with many heating and cooling units. This also keeps its rays securely housed while giving strong purification for your home’s air.

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

This whole-house product is superior to a portable air purifier, which can only clean the air in one area. Portable air purifiers also can’t purify your ductwork or the interior of your HVAC equipment. A clean HVAC system is typically a more efficient one that can even operate longer. And, some portable air purifiers are known for making ozone.

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