UV air purifiers are designed to use short-wave ultraviolet light (UV-C light) to inactivate airborne pathogens and microorganisms like mold, bacteria and viruses. They have the same ultimate goal of all air purifiers: to reduce indoor air pollutants. The technology is also referred to as UV germicidal irradiation, or UVGI air purifiers. This is different from other air purifier technologies that contain UV light technology but do not use it directly against air pollutants. On the market, UV-C air purifiers are currently sold as stand-alone, freestanding devices or as systems installed into pre-existing residential or commercial HVAC units. As air is forced through the device, it passes UV lamps, which directly attempt to disinfect the air by means of germicidal irradiation. The biggest safety concern is that ozone may be generated during this process. Rarely a stand-alone product, UV-C light air purifiers often require additional systems for full effectiveness and are most often included in larger High-efficiency Particulate Arrestance (HEPA) air filtration systems. In fact, the EPA says that a UV-C air purifier does not seem effective as a stand-alone unit because it cannot trap or remove particles.
Should every home run an air purifier to ensure good air quality?
Air Quality is a big issue, and for some people it’s a really big deal. There are many reasons why you might want one in your home – not just because of allergies or asthma. There are also environmental benefits from running one year round. Most air purifiers are very quiet, so you won’t have to worry about noise pollution. There are some purifier models that do require occasional cleaning out or replacing parts after prolonged use, however, these pieces typically come with easy instructions for how to replace those as well. Remembering when it needs maintenance isn’t difficult either – most companies will list on the manual when to replace filters or take it in for a checkup.
