How Do UVC Air Purifiers Work?

September 08, 2020

You likely are aware that the sun’s ultraviolet light (UV) results in painful sunburn. But did you realize that another variety of ultraviolet light can be used to keep your residence’s air clean?

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

There’s another variety of UV light, referred to as UVC. While direct exposure to this ultraviolet light is harmful for your skin or eyes, it can safely be applied to disinfect air, water and some surfaces.

Van Haaften Plumbing & Heating uses this light in several of our systems to improve air filtration in Pella houses.

What is an Ultraviolet Light Used For?

This specific wavelength is classified as “germicidal” because it eradicates the DNA of bacteria and viruses. When pathogens travel through this light, they eventually perish as they can’t spread.

This makes UVC light a strong alternative to chemical disinfection. Germicidal light is employed in many disinfection applications, including medical laboratories and hospitals. It’s also applied to purify drinking water and other liquids made in food processing.

It’s becoming a popular choice to freshen air in residences in Pella. That’s due to the fact it can also eradicate typical indoor contaminants like mold, mildew and bacteria. This is an added perk for loved ones who deal with seasonal allergies or asthma.

How to Use Germicidal UV Light in Your Home

We put a germicidal UV light in your HVAC system’s ductwork. Since the light is put inside the ductwork, it makes it compatible with most heating and cooling systems. This also keeps its light carefully housed while delivering powerful cleaning for your home’s air.

Filthy air is freshened in a two-step process, first moving through your air filter and then the UV light prior to circulating around your home. Even when your heat or air conditioning isn’t running, these lights still run to keep your air, ductwork and home comfort unit clean.

This whole-house solution is better than a portable air purifier, which is restricted to cleaning the air in one area. Portable air purifiers also can’t purify your ductwork or the innerworkings of your HVAC system. A clean HVAC system is often a more efficient one that could even last for an extended period of time. And, many portable air purifiers are notorious for producing ozone.

When thinking about adding a germicidal lamp to your residence, it’s critical to buy one that doesn’t create ozone. While ozone is good at getting rid of odors and chemicals, it can also irritate your lungs and cause other respiratory troubles.
