Frequency Asked Questions
FAQ: What is ultraviolet germicidal irradiation?
Answer: Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. UVGI is used in a variety of applications, such as food, air, and water purification.
FAQ: How effective is ultraviolet sanitization for killing viruses and bacteria?
Answer: A 2014 study in the American Journal of Infection Control found that UV light killed 100 percent of several types of bacteria commonly found on surfaces after just five seconds. According to the researchers, a UVC device is a reasonable alternative to using chemicals to disinfect surfaces.
The effectiveness of UV depends on the length of time a microorganism is exposed to UV, the intensity and wavelength of the UV radiation. The most effective wavelength for destroying the DNA of microorganisms is 265 nm as shown below. The majority of the research in this area has shown a UV light with 2-4 mJ per cm square can kill most germs.

FAQ: How the Quince UV Sanitizer should be used to avoid any health issues?
Answer: The best way to avoid any safety risks, our devices are suggested to be used inside an enclosed box or bag to sanitize the items inside. The best case would be using enclosures that have reflective interior, such as thermally isolated bags, to reflect the UV light and expose all sides of the items inside to the UV light for sanitization. The items will be completely sanitized in 10 minutes using Quince H0400 and in 2 minutes using Quince H3300.
Our UV sanitizer devices are strongly recommended not to be pointed toward your own or others body.
FAQ: Can UV sanitization remove smell from clothes?
Answer: Yes. UV light kills viruses, bacteria and other microorganisms, some of which are responsible for creating smell in the clothes. By removing these germs your clothes will smell a lot fresher.
FAQ: Is it safe to sanitize food with UV light?
Answer: The use of ultraviolet light has been a part of food industry for more than 50 years. UV-C is proven to reduce or eliminate E. coli, Salmonella, Listeria, and other foodborne pathogens. Many food products such as juices and apple cider, as well as grains, cheese, baked items, frozen foods, fresh fruits and vegetables, and liquid egg products, among other food and beverage items are processed using UV-C.
FAQ: What is the difference between ultraviolet LEDs and UV lamps?
Answer: Historically, mercury lamps have been the only option for disinfection and sterilization. With UV LED technology advances, there are new options that are smaller, more robust, toxin-free, long lived, energy efficient and allow for infinite on/off switching. This allows solutions to be smaller, battery powered, portable and with instant full light output. UV lamps emit lights in all directions and therefore cannot be controlled, while in LEDs, the light beam is highly directional and can be focused in a specific area.
Low pressure mercury lamps emit an almost monochromatic light with a wavelength of 253.7nm. Low-pressure mercury lamps (fluorescent tubes) and high-pressure mercury lamps are also used for disinfection and sterilization. These lamps have a much broader spectral distribution that includes germicidal wavelengths. UVC LEDs can be manufactured to target very specific and narrow wavelengths. This allows solutions to be tailored to the particular application need.
FAQ: Is Quince UV device harmful for my eye?
Answer: Any light intensity (ultraviolet, visible or infrared) that is above the eye's tolerance limit can cause an eye safety issue. Looking directly at our UV sanitizer devices for longer than 5 seconds creates major risks for the safety of your eyes.
FAQ: Can Quince UV Sanitizer be used for sterilizing baby stuff?
Answer: Yes. Just place the turn on the UV sanitizer next to the items you need to sanitize inside a box or a bag. Make sure to close the box or bag and leave it for 10 minutes. After that all items inside are completely sterilized.
FAQ: Why the beam of my UV sanitizer is weak?
Answer: Not seeing the beam of the UV sanitizer does not mean it is weak. Our UV devices use 260-300 nm deep ultraviolet light, which is proven to be the most effective wavelength for destroying the DNA of microorganisms. This light spectrum is hardly visible to the human eye.
