Can a single wavelength eliminate all bacteria?

Yes, a single wavelength can be used. However, since bacteria have different optimal absorption wavelengths, power and time of irradiation need to be calculated to achieve the desired disinfection level.

Are UVC disinfection devices safe?

UVC devices must be used properly. They produce light much stronger than sunlight and can cause severe skin burns or eye damage if exposed. Some devices also produce ozone or heat, so safety compliance and training are essential.

Are there performance standards for UVC disinfection devices?

There is a lack of uniform standards, so consumers should look for third-party testing and certification by organizations like UL, CSA, or DVGW-OVGW. Industry groups are working to develop better testing standards for healthcare applications.

Product Q&A

Q:Can UVC help prevent transmission by reducing contamination?

Based on existing evidence, yes. UVC light has been used for over 40 years to disinfect water, air, and surfaces against human pathogens, and all tested bacteria respond to UV disinfection at appropriate doses.

Q:What is the sterilizing range of UV?

The sterilization range important for water and air disinfection is about 200-300nm, which is the range absorbed by DNA. The bactericidal range extends up to 300nm.

Q:What is the optimal wavelength for disinfection?

While 254nm is common due to mercury lamps, 265nm is generally considered optimal as it is the peak of the DNA absorption curve. However, a range of wavelengths have disinfection effects.

Q:What is the difference between UVC LEDs and mercury lamps?

Mercury lamps emit nearly monochromatic light at 253.7nm with broader spectral distribution. UVC LEDs can be focused on narrow specific wavelengths, allowing solutions to be tailored to specific needs, and are smaller, more powerful, and energy-efficient.

Q:Does the peak absorption wavelength of DNA vary by bacteria?

Yes, different types of bacteria have different peak absorption wavelengths, but most are around 265nm.
