How Germicidal UV Light Works

September 08, 2020

You probably know that the sun’s ultraviolet light (UV) causes painful sunburn. But were you aware that another kind of ultraviolet light can be useful for keeping your home’s air clean?

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

There’s another type 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 used to disinfect air, water and certain surfaces.

Pliescott HVAC Services LLC uses this light in some of our solutions to enhance air filtration in Cambridge houses.

What is an Ultraviolet Light Used For?

This precise wavelength is referred to as “germicidal” since it wipes out the DNA of bacteria and viruses. When pathogens pass through this light, they eventually cease to exist because they can’t multiply.

This makes UVC light a potent substitute to chemical disinfection. Germicidal light is used in a lot of disinfection procedures, such as medical laboratories and hospitals. It’s also used to clean drinking water and other liquids made in food processing.

It’s growing in popularity to purify air in residences in Cambridge. That’s since it can also wipe out frequent indoor contaminants like mold, mildew and bacteria. This is an added perk if someone in your household has seasonal allergies or asthma.

How to Use Germicidal UV Light in Your Home

We install a germicidal UV light in your HVAC system’s ductwork. Since the light is put in the ductwork, it makes it compatible with most heating and cooling units. This also keeps its light securely housed while giving powerful disinfection for your residence’s air.

Dirty air is purified in a two-step process, first moving through your air filter and then the UV light in advance of flowing throughout your residence. Even when your heat or air conditioning isn’t running, these lights still operate 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 lone area. Portable air purifiers also can’t freshen your ductwork or the inside of your HVAC system. A clean HVAC system is usually a more efficient one that could even run for a longer life span. And, many portable air purifiers have a bad reputation for producing ozone.

When considering buying a germicidal lamp for your residence, it’s critical to choose one that doesn’t produce ozone. While ozone is good at eliminating odors and chemicals, it might also irritate your lungs and create other respiratory problems.
