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 realize that a different type of ultraviolet light can be used to keep your residence’s air clean?

The sun lets off two types of harmful UV rays, UVA and UVB. These dangerous rays can result in sunburn, skin cancer, wrinkles and other kinds 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 purify air, water and certain surfaces.

Discount Mechanical Heating & Plumbing Services uses this light in some of our solutions to improve air filtration in Anchorage houses.

How Ultraviolet Light is Used

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

This makes UVC light a powerful replacement to chemical disinfection. Germicidal light is used in a lot of disinfection uses, like medical laboratories and hospitals. It’s also applied to purify drinking water and other liquids made in food processing.

It’s becoming more popular to disinfect air in residences in Anchorage. That’s due to the fact it can also eradicate frequent indoor contaminants such as mold, mildew and bacteria. This is an additional advantage for family members who suffer from seasonal allergies or asthma.

Installing Germicidal UV Light in Your House

We put a germicidal UV light inside your HVAC system’s ductwork. Since the light is set within the ductwork, it makes it compatible with most heating and cooling units. This also keeps its light safely housed while providing strong cleaning for your home’s air.

Filthy air is cleaned in a two-step process, first flowing through your air filter and then the UV light prior to moving throughout your home. Even when your heat or air conditioning isn’t working, 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 is limited to cleaning the air in a single room. Portable air purifiers also can’t clean your ductwork or the inside of your HVAC equipment. A clean HVAC system is often a more efficient one that may even run longer. And, the majority of portable air purifiers are known for producing ozone.

When thinking over getting a germicidal lamp for your residence, it’s critical to select one that doesn’t make ozone. While ozone is good at eradicating odors and chemicals, it might also irritate your lungs and cause other respiratory troubles.
