UVC Wavelength 253nm

About UVC Wavelength

UVC Wavelength 253nm is particularly useful. UV rays come from sunlight with different types of spectrum, categorized into 3 different wavelengths: UVA(320nm ~ 400nm), UVB(280nm ~ 320nm), UVC(200nm ~ 280nm).

Among these spectrums, UVC Wavelength 253nm provides the strongest germicidal effect, which has been used in various applications.  Furthermore, 253.7 nm is proven to be the best spectrum, inactivating bacteria and viruses in the air and surface.

UVGI is a viruses inactivation technology for your business.

  • UV-C damages DNA/RNA

  • Damaged organisms can’t replicate

  • Maximum germicidal effectiveness with UVC spectrum

  • Used for air, surface, and water treatment

AIAN UV Sterilizers are a robust UVGI machine suitable for businesses and healthcare applications since AIAN Sterilizers not only uses UVC 253.7 nanometer together with InfraRed or plasma ionizer but also it is a chamber type without exposing rays to your valuable space.  Furthermore, you will find other valuable features: fastest operation(20 min or 30 min; depending on the models), one-touch operation, audio messaging, and durable body, which allows AIAN Sterilizer a perfect fit for businesses. Check further details of different types of AIAN Sterilizers.

AIAN Sterilizer and Dryer is an example of using UVC 253.7 nanometer with InfraRed combined together for sterilizing baby bottles.  Here is the video to watch.


It works against COVID-19, proven by recent research on UVC 222 nanometer spectrum at Hiroshima University.  UVC 222 nanometer removes COVID-19, while it is safe for humans; however, this particular spectrum doesn’t penetrate inside of living cells. Above 253 nanometer spectrum is highly effective for UVGI (Ultraviolet ultraviolet germicidal irradiation) applications since the spectrum breaks up the DNA of viruses and bacteria.
