Because indoor air can experience a significant amount of pollution, many HVAC contractors recommend installing an air purifier in the home. One of the best methods for purification is ultraviolet (UV) light, which will remove germs, mold, and mildew from your indoor air. It also doesn’t affect your health or the environment, ensuring your family is safe. Below is more information about how these purifiers will improve your air quality.

What Is UV Light?

Ultraviolet light is a type of electromagnetic radiation that the sun produces. However, you can’t see it with the naked eye or feel it on your skin. This is because UV light has a short wavelength of 100 to 400 nanometers, and the light receptors in your eyes can only detect 400 to 700 nanometers long. Also, you only feel heat from infrared light, which has a wavelength from 700 to 1 million nanometers long. 

There are three types of UV light: 

• UV-A: Most of the sun’s radiation that reaches the Earth is this form of UV light. Many tanning booths utilize this light, and it is one of the most common causes of premature aging and wrinkles.
• UV-B: This form of radiation is what causes sunburns. It damages the top layer of skin.
• UV-C: This UV light is the most harmful to living organisms. However, the atmosphere blocks it before it can reach humans. Artificial UV-C lights can purify the air, and are not as dangerous as the natural form.

How Does UV Light Purify the Air?

Natural UV-C light is dangerous because it destroys the nucleic acids in cells and disrupts DNA. This means that the cells will either die from prolonged exposure or fail to perform vital functions.

However, purifiers that use UV-C technology work by pulling air into the device where it flows through a fine filter. Once the air reaches this point, it enters a compartment that shines a UV light. This prevents UV-C radiation from entering the room, as it stays contained inside the purifier. Then, the light kills harmful pathogens before the air circulates back into the room.
