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 know that another variety 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 harmful rays can result in sunburn, skin cancer, wrinkles and other signs of premature aging.

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

Ilten's Incorporated uses this light in several of our solutions to enhance air filtration in Cedar Rapids homes.

How Ultraviolet Light is Used

This distinct wavelength is called “germicidal” since it destroys the DNA of bacteria and viruses. When pathogens move through this light, they eventually perish since they can’t multiply.

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

It’s growing in popularity to disinfect air in residences in Cedar Rapids. That’s since it can also eliminate frequent indoor contaminants like mold, mildew and bacteria. This is an added benefit for loved ones who deal with seasonal allergies or asthma.

Uses for Germicidal UV Light in Your House

We put a germicidal UV light in your HVAC system’s ductwork. Since the light is put inside the ductwork, it makes it compatible with most heating and cooling units. This also keeps its rays securely restricted while delivering powerful cleaning for your house’s air.

Contaminated air is purified in a two-step process, first traveling through your air filter and then the UV light before moving throughout your home. Even when your heat or air conditioning isn’t operating, these lights still work to keep your air, ductwork and home comfort equipment clean.

This whole-house option is greater than a portable air purifier, which is restricted to cleaning the air in a single room. Portable air purifiers also can’t purify your ductwork or the interior of your HVAC system. A clean HVAC system is typically a more efficient one that may even last for an extended period of time. And, the majority of portable air purifiers are notorious for creating ozone.

When thinking over getting a germicidal lamp for your residence, it’s important to get one that doesn’t produce ozone. While ozone is fantastic at eliminating odors and chemicals, it may also irritate your lungs and create other respiratory troubles.
