UV or ultraviolet lights are known to deactivate the DNA of dangerous bacteria, viruses, fungi, mold, and other microorganisms. These lights have been used in hospitals, universities, urgent care centers, and air purifiers for decades for sterilizing equipment and maintaining a sanitary environment. 

It is no secret that the air inside our homes is a lot more polluted than the air outside. The Environmental Protection Agency (EPA) claims that indoor air pollution is among the top five environmental hazards in the United States. On average, Americans spend 90% of their time indoors, making them more vulnerable to the ill effects of indoor pollutants.
