Can a single wavelength eliminate all bacteria?

Yes, a single wavelength can be used, but bacteria have different optimal absorption wavelengths requiring calculated power and time.

Are UVC disinfection devices safe?

They must be used properly; UVC light can cause skin burns and eye damage, and some devices produce ozone, so safety compliance is essential.

What performance standards should be considered for UVC devices?

Look for third-party testing and certification by organizations like UL, CSA, or DVGW-OVGW due to the lack of uniform standards.

Product Q&A

Q:Can UVC help prevent virus transmission by reducing contamination?

Yes, based on evidence, UVC light has been used for over 40 years to disinfect water, air, and surfaces against pathogens, and all tested bacteria respond to UV disinfection.

Q:What is the sterilizing range of UV?

The sterilization range is about 200-300nm, which is the range absorbed by DNA and RNA, effective for water and air disinfection.

Q:Is 254nm the optimal wavelength for disinfection?

No, 265nm is generally considered optimal as it matches the peak of the DNA absorption curve, though a range of wavelengths is effective.

Q:What are the advantages of UVC LEDs over mercury lamps?

LEDs are smaller, more powerful, non-toxic, longer-lasting, more energy-efficient, and allow instant full-light output compared to mercury lamps.

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

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