How Germicidal UV Light Works

September 08, 2020

You probably know that the sun’s ultraviolet light (UV) causes painful sunburn. But did you realize that a different type of ultraviolet light can be installed to keep your house’s air clean?

The sun lets off two types of harmful UV rays, UVA and UVB. These damaging rays can cause sunburn, skin cancer, wrinkles and other signs of premature aging.

There’s another variety 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 purify air, water and certain surfaces.

Dial One Mears Air Conditioning & Heating Inc uses this light in several of our solutions to boost air filtration in Phoenix houses.

Applications for Ultraviolet Light

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

This makes UVC light a potent alternative to chemical disinfection. Germicidal light is applied in many disinfection applications, including 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 disinfect air in residences in Phoenix. That’s due to the fact it can also eradicate common indoor contaminants like mold, mildew and bacteria. This is an added advantage for family members who suffer from seasonal allergies or asthma.

How to Use Germicidal UV Light in Your Home

We install a germicidal UV light within your HVAC system’s ductwork. Since the light is put within the ductwork, it makes it compatible with most heating and cooling systems. This also keeps its rays securely confined while delivering powerful disinfection for your home’s air.

Contaminated air is freshened in a two-step process, first moving through your air filter and then the UV light before moving across your home. Even when your heat or air conditioning isn’t running, these lights still function 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 a lone room. Portable air purifiers also can’t purify your ductwork or the interior of your HVAC equipment. A clean HVAC system is usually a more efficient one that can even work for an extended period of time. And, many portable air purifiers have a bad reputation for creating ozone.

When thinking about getting a germicidal lamp for your house, it’s critical to buy one that doesn’t make ozone. While ozone is great at eliminating odors and chemicals, it might also irritate your lungs and lead to other respiratory troubles.
