The Difference Between UVA, UVB, and UVC Light — And Why Do You Need UV-C Air Purifiers

You often hear about ultraviolet light when purchasing sunglasses or sunblock. More often than not, the advice is to use these items for enhanced protection against both UVA and UVB rays. What you may not know is that there exists a third type of UV light called UVC. In addition, this light can be used to help purify the air in your home, thus protecting you from various pathogens, like the cold and flu.

Types of UV Light

While you may not be able to see ultraviolet light due to its relatively short wavelength when compared to visible light, it still exists. Here is a quick primer:

• UVA- Wavelength of 320 to 400nm. Comprises 90 to 95 percent of the UV radiation on Earth. It is typically used for fluorescent inspections and to polymerize certain adhesives. It is considered the safest of all types of UV light.
• UVB – Wavelength of 280 to 320nm. Comprises 5 to 10 percent of UV radiation on Earth. It is what is responsible for sunburns and skin cancer. In industries, it’s used to cure certain inks and lacquers.
• UVC – Wavelength of 200 to 280nm. It is eliminated in nature by the Earth’s atmosphere. In industries, it is used to kill microbes for sterilization purposes.

The Right UV Purifiers for Your Home

The best type of UV purifiers is one that contains UVC light. Having UV air purifiers as the perfect complement to air conditioning systems can help improve indoor air quality by neutralizing viruses and other microbes.
