What makes UV-C different from UV-A and UV-B?

You may already have encountered UV-C sanitizing devices in the mall or online, and wondered what UV-C stands for. We all know that these devices utilize ultraviolet lights to kill microorganisms such as germs, bacteria, and viruses, however not many of us know what makes it unique from those ultraviolet lights emitted by the sun.

In this article, I will unfold the seemingly confusing deal about ultraviolet lights—what makes one different from the other. Make sure to read further to find out!

What makes UV-C different from UV-A and UV-B?


So, here’s the thing: The sun emits three various types of UV radiation: UV-A, UV-B, and UV-C. These three have the potential to bring skin damage, but each type affects your skin differently.

Let’s start with UV-A—this type of ultraviolet radiation accounts for 95% of the radiation that reaches the planet’s surface and skin’s second layer, causing skin problems such as skin cancer, sun spots, wrinkles, and other manifestations of skin aging when exposed for too long. UV-B, also known as showave light, can also affect the skin, particularly its top layer. It can cause sunburn, skin reddening, and in worst scenarios, skin cancer.

These two types of UV radiation bring the greatest risk to skin damage. The last type, UV-C, is the shortest among all UV rays. This type of UV radiation never reaches the Earth’s surface because the ozone layer absorbs it. Even so, UV-C can be produced in medical laboratories, as well as be present in man-made sources such as welding torches and mercury lamps. It is not considered a risk for skin cancer and sunburn.

UV-C is the only type of ultraviolet light that can neutralize harmful microorganisms, including disease-causing germs, bacteria, and viruses by disabling their ability to thrive and infect humans. This is mainly the reason why brands incorporate UV-C’s sanitizing power on their tools to create well-developed, convenient, and effective sanitizing tools that can be used in our households today.

UV-C sterilizers: Are they effective?

According to several clinical studies, the power of UV-C sterilizers to disinfect items, surfaces, and even confined spaces effectively is proven and tested. If you’re still in doubt, you may check out various laboratory findings in Consumer UV Guide.

Not only will you encounter scientific findings, but you will see various UV-C sterilizer brands and tools to choose from. If you want to try using a UV-C sanitizing device, but are unsure of what to get, you can speak to one of their UV specialists online for a recommendation.

Here are some customer reviews about the e-commerce website:

"Working in a clinical setting exposes me to a number of bacteria, germs, and viruses. I wanted something to help me safeguard against exposure so I started researching UV-C sanitizers. There's so much confusing information out there. I'm glad I found you guys. You made the research and buying process so easy!" – Roberta M.

"I was looking for a way to keep my classrooms germ free without having to constantly spray and wipe. When I searched Google, I found a dizzying amount of choices. I'm glad I found this site. I used the 'speak to a UV specialist function and they called me at my preferred time and spent 30 minutes with me to find the right device. Absolutely 5-stars. Give them a try." – James K.
