Infrared vs Ultraviolet Sterilizer Cabinets: What Is the Difference?

Infrared and UV sterilizer cabinets are often mentioned—but what are they, how do they differ, and which is better? CHINENG explains.

What is an infrared sterilizer cabinet?

It disinfects by high heat with strong kill performance, but tableware must tolerate temperature—plastics and some materials may warp.

What is a UV sterilizer cabinet?

It works at low temperature. UV travels in straight lines with weak penetration and kills only exposed microbes—place items in the light path.

Key differences

Infrared is high-heat with lasting residual effect but harsh on plastics, melamine, and wood chopsticks. UV suits more materials yet has shadows and no lasting residual kill.

Which is better?

Choose UV for plastic, wood, or melamine; choose infrared for ceramic, glass, or stainless steel.

Either way, buy reputable brands for quality and after-sales support.
