How Do UVC Air Purifiers Work?

September 08, 2020

You likely are aware that the sun’s ultraviolet light (UV) is to blame for your painful sunburn. But were you aware that another kind of ultraviolet light can be useful for keeping your home’s air clean?

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

There’s another concentration of UV light, called UVC. While direct exposure to this ultraviolet light is harmful for your skin or eyes, it can safely be used to clean air, water and some surfaces.

Three Rivers Heating & Cooling uses this light in several of our products to enhance air filtration in Portland houses.

Applications for Ultraviolet Light

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

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

It’s becoming more popular to purify air in homes in Portland. That’s due to the fact it can also eradicate common indoor contaminants like mold, mildew and bacteria. This is an additional perk for family members who suffer from seasonal allergies or asthma.

Installing Germicidal UV Light in Your Home

We place a germicidal UV light inside your HVAC system’s ductwork. As the light is installed inside the ductwork, it makes it compatible with many heating and cooling units. This also keeps its light safely restricted while delivering powerful disinfection for your home’s air.

Filthy air is cleaned in a two-step process, first traveling through your air filter and then the UV light prior to spreading around your residence. Even when your heat or air conditioning isn’t working, these lights still function to keep your air, ductwork and home comfort system clean.

This whole-house option is superior to a portable air purifier, which is limited to cleaning 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 often a more efficient one that can even run for an extended period of time. And, many portable air purifiers are known for making ozone.

When considering getting a germicidal lamp for your residence, it’s critical to look for one that doesn’t produce ozone. While ozone is great at eliminating odors and chemicals, it can also irritate your lungs and lead to other respiratory troubles.
