Does UV phone sanitizer work?

With the Coronavirus Disease (COVID-19) getting more and more serious, it is now a must and a top priority for everyone to eliminate bacteria. A recent University of Arizona study found our phones can carry 10 times more bacteria than most toilet seats. After knowing this astounding result, do you still think it is already fine to sanitize your phone’s screen with alcohol wipes? 

When it comes to killing germs entirely, a UV phone sanitizer seems to be the best candidate that comes on the pudding time. Before determining whether UV sanitizer works, let us delve into what is a UV phone sanitizer and how does it work. A UV phone sanitizer is a UV disinfection box with UV lights that you just need to put your phone inside and the ultraviolet light inside the box will automatically help your phone to sanitize and disinfect, giving your cellphone a high-quality full bath.


Pros and Cons of a UV phone sanitizer

Many people may doubt the effectiveness of UV phone sanitizer. However, it can be assured that the UV sanitizer is undeniably in effect as ultraviolet lights have long been embraced by hospitals as a cleaning tool to decontaminate rooms. Besides, it has been examined that UVC rays can successfully kill between 94.98% and 99.99% of germs, which is far more effective than simply clean your phones with alcohol wipes.

Now, the phone UV sanitizer serves as a mini-version cleaning tool to disinfect phones. It has been proved that UV light is a particularly good option for sanitation because it kills bacteria regardless of drug resistance and without toxic chemicals. There are three main types of UV rays: UVA, UVB as well as UVC, which is adopted by the UV light sanitizer box. Since UVC rays have the shortest wavelength, thus they have the highest energy making them capable of killing bacteria and viruses, which are also called pathogens. UVC light has a wavelength of between 200 and 400 nanometers. It is highly effective at decontamination seeing that it destroys the molecular bonds that hold together the DNA of viruses and bacteria, including ‘superbugs’, which have developed a stronger resistance of antibiotics.


However, sad to say, every coin has two sides. Even though UV lights are conductive in disinfection, it has a little drawback. Research has found out that broad-spectrum UV light can be a health hazard linked to diseases such as skin cancer and cataracts and humans cannot be in the room when it is used. Still, the thing isn’t that bad and there is a silver lining. 


Lately, researchers have been working with narrow-spectrum UVC rays (207-222 nm) and have thus found that this type of UVC light kills bacteria and viruses without penetrating the outermost cell layer of human skin. A 2017 study showed that 222nm UVC light killed methicillin-resistant Staphylococcus aureus (MRAS) bacteria just as effective as a 254nm UVC light which would be toxic to human. This study was repeated in 2018 on the H1N1 virus, and narrow-spectrum UVC light was again found to be effective at eliminating the virus. All this comes down to one point: narrow-spectrum UV lights are beneficial to decontamination without taking a toll on humans’ health.


What do you need to consider when buying a UV phone sanitizer?

Now, it is proved that a UV phone sanitizer does work without posing any threats to our health. Are you yearning to get one as soon as possible? That’s good news but do you know what should be considered when buying a UV phone sanitizer? Here comes the reminder: make sure you purchase the right wavelength. Please note that UV-C is the only category of UV wavelengths that consistently work for sterilization, as this wavelength range is the only range capable of direct DNA and RNA destruction. Also, be aware of human, animal, and material safety risks when using UV-C. Please bear in mind that UV-C wavelengths are far more powerful than other forms of ultraviolet which can cause sunburn in human skin and also lead to skin cancer. Never expose humans or animals to UV-C radiation. Because UV-C rays are invisible, there is an extra risk of unintended exposure. Therefore, when considering UV-C as a sterilization method, be very careful when handling a UV sanitizer.
