How Do UV Lights Work?

When it comes to indoor air quality, you have a wide variety of options available to you. Some products raise or lower the humidity levels in your home, while others serve to filter out the dust and other contaminants. But here in Salt Lake City, we often recommend UV germicidal lights as a key part of any indoor air quality system. They do the most important work of all: eliminating germs and bacteria to keep your family healthy. With a UV light system installed, you can help reduce instances of illness in your household. This is of particular benefit to the elderly, to newborn babies, and to people suffering from asthma or similar conditions, but in truth, everyone could benefits from fewer creepy crawlies circulating through your air. How do UV lights work? We’ve provided a quick breakdown below.

Ultraviolet Light

The UV stands for “ultra-violet,” which, if you remember your middle-school science class, is a light wave beyond our ability to see. It appears naturally in sunlight, and will cause us to tan or burn if we spend a lot of time in the sun. UV light is quite harmless in small doses, at least to humans and pets. Indeed, you can often see it being used at rock concerts or at rides in amusement parks, where it makes our white clothes glow in the dark. (That’s the light interacting with chemicals in our laundry detergent.) But for germs and similar tiny organisms, UV light spells lights out for good.

How it Works

A germicidal light is placed safely at the apex of your air conditioning ducts, sending a field across the width of the duct that all of the air must pass through. As germs and bacteria touch it, it interferes with their DNA, rendering them unable to replicate. Not only do they die a quick death, but they can’t spread, and as the system circulates the air through the ducts, your whole home is “scrubbed clean” of them.
