Standard air filtration systems are used in most homes, but some come with technologies that you wouldn’t at first think of as something that will help clean the air you breathe. Ultraviolet (UV) light is one such example, and air purifiers with this innovation are fast gaining traction among homeowners.
Today, the AC replacement and heating repair pros of Cool Zone Air Conditioning & Heating shine a spotlight on air purifiers with germicidal UV light and how they function.
UV air purifiers are systems that use short-wave ultraviolet light to inactivate bacteria, viruses, mold and other airborne pathogens or microorganisms. They have the same purpose as standard air purifiers—to reduce indoor air pollutants.
On the market, they’re sold either as stand-alone devices or systems that can be installed into pre-existing heating and cooling units. Heating and AC repair pros also note that for the purifiers to be fully effective at cleaning indoor air, they’re often included in larger high-efficiency particulate arrestance (HEPA) air filtration systems.
To better understand how UV air purifiers work, it’s worth discussing UV light. UV light is a part of the light spectrum that can’t be seen by the naked eye, but can certainly be felt after prolonged sun exposure. UV-C light, the third type of UV light after UV-A and UV-B, is the most harmful. It’s also responsible for the main disinfecting activity of these air purifiers. It can destroy cells, particularly nucleic acids. This disrupts their DNA, killing them instantly or leaving them incapacitated.
UV air purifiers work by pulling air into the appliance. The air then passes through a fine filter, like a HEPA filter. It then goes on to a small chamber where it’s exposed to UV-C light that bombards microbes and pathogens with all its energy until it damages their DNA.
Now that we’ve arrived at this so-called “new normal,” it’s more important than ever to ensure you’re well-protected against viruses and germs. As many of us are staying indoors most of the time, you need to have the right air purifier to keep your air clean and you and your family safe.
