What's a UV-C Light Filter? Is it Safe to Use?
A UV-C light filter with one of four types of ultraviolet light (UV-A, UV-B, UV-C and UV-V) is widely used in air purifiers or serves as a standalone air sanitizer to remove germs, mold spores, mildew, bacteria and even viruses.
This air purification technology can be used not only in high-end units, but also in inexpensive ones.
In real-world use, the UV-C light filter can work on its own to end the life of bacteria and viruses, but you still need other physical air filters to collect airborne particles. For our air purifiers, the most common air filter to be paired with the UV-C light filter is the True HEPA filter.

I hope you're ready to learn more about the UV-C LIGHT FILTER. Let's just keep reading.
What's the UV-C Light Filter?
UV-C light, such as radio waves and x-rays, is an invisible source of electromagnetic radiation. It consists of all wavelengths of electromagnetic radiation, including light, radio waves and x-rays, which are grouped by frequency and wavelength.
UV light is a special form of radiation that can not be detected by the naked eye since it is part of the invisible portion of the electromagnetic spectrum. Its wavelength is, to be exact, from 400 nm (750 THz) to 100 nm (30 PHz), shorter than that of visible light.
In air purifiers, the UV-C light filter with a wavelength of just 256 nm is capable of effectively destroying microorganisms such as germs and viruses. By destroying the cells, the UV-C light filter sterilizes the microorganisms. However, it prevents the DNA reproduction of these microorganisms, but it does not remove them from the air.
Therefore, if you do use a UV-C light filter on your own, it will only destroy bacteria and viruses that cause many of your diseases, so it will not eliminate other possible allergens such as dust, dust mites, pollen or pet dander. You will need the True HEPA filter to do this job. Below are the most common air purifiers with the combination of True HEPA filter and UV-C light filter.
Is there UV-C Light Harmful to Humans?
While several air purifier manufacturers have claimed that UV-C light is absolutely harmless to humans, you need to know the essence of UV-C light.
The strength of the UV-C light is greatly decreased over time, so the farther away you are from the UV-C light source, the less exposed you are to it. Moreover, the absorption length of UV-C radiation in human skin is really, really short, so that it can't reach the living cells.
UV-C light usually does not cause damage to humans. Perhaps significantly, the UV-C light bulb is fully concealed within the air purifier, and there's no chance you'll be exposed to ultraviolet radiation.
Nevertheless, the UV-C light filter is capable of releasing a quantity of ozone, and ozone is also responsible for causing asthma and many other respiratory problems. If you don't know, or if you experience the side effect of using a UV-C light filter, this function should be switched off as soon as possible.
You should check this California Certified Air Cleaning Devices to help you learn which air purifier is certified by the California Air Resources Board (CARB) to be safe to use with or without a UV-C light filter. Or else, all you need to do is read our air purifier reviews to see whether you can trust one air purifier or not.
