As people's awareness of health issues continues to increase, many companies have released various UV sterilization products to the market. You may be curious about how it works and whether it is worth trying. Let's go deeper.
Which type of UV can kill germs?
As far as UV disinfectants are concerned, not all brands of UV are suitable. As a reference, ultraviolet (UV) is also called "beyond violet" and can be divided into three bands, namely UVA, UVB and UVC, with reduced wavelength and increased energy. In terms of ultraviolet disinfection, only ultraviolet (100-280nm) has the highest power, which is sufficient to kill microorganisms including viruses and bacteria. Therefore, when you decide to use UV disinfection products as daily necessities, please remember to ensure that the wavelength of the UV lamp is between 100-280nm.
How does UV kill germs?
In 1877, the research found that UVC has bactericidal and antibacterial effects, which can kill bacteria and prevent bacterial growth. There is no doubt that UV sterilization is an invaluable and growing solution, and its powerful features can prevent the spread of infection. In particular, the most common use of ultraviolet rays is usually related to the medical field that helps to create a clean workspace.
For more in-depth information, bacteria on the surface of the object will be killed by ultraviolet germicidal radiation (UVGI). It can inactivate microorganisms by destroying and destroying the structure of their DNA molecules, making them unable to reproduce and preventing reproduction. It is considered dead because it is no longer contagious. For your reference, the DNA absorption peak of ultraviolet light is 260 nm, which is in the range of UVC wavelength (100-280nm). However, sterile UVC lamps can purify 99% of most bacteria.
Will it be harmful to humans?
Long-term investigations and studies have shown that if installed correctly, UVGI is safe and effective in the field of disinfection, which can inhibit the spread of a variety of airborne infections. In the long run, although UVC lamps directly exposed to the skin or eyes can cause temporary adverse reactions, they will never cause any permanent damage when installed correctly.
What sterilization application is UV lamp applied?
Medical use-used in the disinfection system and a wide range of facilities in different rooms of the hospital.
Household-UVC germicidal lamp, used for surface disinfection and air disinfection.
Daily use - Portable UV sterilizer for disinfecting belongings everywhere and anytime.
