Are UVC disinfection devices safe?

They must be used properly. UVC light is stronger than sunlight and can cause skin burns or eye damage if exposed. Safety considerations must be addressed in operations manuals and user training.

What are the performance standards for UVC devices?

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

What is the warranty period for this product?

We provide a 3-year warranty for this UVC LED product.

Product Q&A

Q:Can UVC help prevent transmission by reducing contamination?

Yes, based on existing evidence. 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 is about 200-300nm, which is the range absorbed by DNA. The bactericidal range extends up to 300nm.

Q:Is 265nm the optimal wavelength for disinfection?

Yes, 265nm is generally considered optimal because it matches the peak of the DNA absorption curve, whereas 254nm is the peak for mercury lamps.

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

LEDs are smaller, more powerful, non-toxic, longer-lasting, more energy-efficient, allow more switching times, and enable instant full-light output.

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.
