What do UV air purifiers do in your home?

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.

It may surprise you but the air pollution in your home can be worse than outdoor pollutants. The main benefits of HVAC UV lights are:

1. Improved efficiency and airflow
2. Reduced energy costs
3. Elimination of mold and mildew
4. Reduced allergies, asthma, and respiratory symptoms
5. Kills viruses and bacteria
6. Reduces odors
7. Improves indoor air quality
