UV-C disinfection boxes in the test: protection against viruses, bacteria and co

How often do you pick up your smartphone, key and wallet every day without washing your hands first? If you have a bad feeling about it, you can easily kill germs, bacteria, viruses and sometimes even fungi with a UV-C box.

The high-energy radiation from UV-C light attacks the genetic make-up of viruses, germs, bacteria and the like and kills them in just a few minutes. However, UV-C light is also harmful to humans in direct contact: the eyes and skin are acutely endangered, and the high-energy light is also potentially carcinogenic. We can therefore only advise against using open UV-C lamps.

If the light is used in a closed system, things are different. In the course of the corona pandemic, boxes for domestic use are increasingly coming onto the market that disinfect everyday objects with UV-C light and are safe to use.

We looked at models from Philips and Einova, the latter combining disinfection with charging technology.

Philips UV-C mini disinfection box

Philips is part of Signify, the world market leader in lighting, and has had expertise in UV-C disinfection for 35 years, primarily in the professional sector. For home use, Signify presented the Philips UV-C disinfection box for 180 euros in March 2021. It is quite large and even held an iPad Air in our test.

The UV-C mini disinfection box for 55 euros is much smaller and can even be taken with you when traveling. A USB-C cable is included for power supply; buyers have to borrow the 5V power supply unit from the smartphone. This is annoying at home, but offers the option of connecting the box to a power bank on the go.

Four UV-C LEDs sit on the back of the box and radiate the interior. According to Signify, they eliminate viruses, bacteria, mold and spores. So that the inserted parts are also illuminated from below, large knobs are attached to the floor, which prevent an object from lying flat.

The interior is elongated and open. It only fits a smartphone, but thanks to its height of 4.4 centimeters it can also hold larger things like a computer mouse. At the longest point, the interior measures 21.2 centimeters, with the long sides being strongly rounded. In front of and behind the phone, for example, you can pack in-ears or smaller pieces of jewelry.

Safe operation

A flashing LED around the power switch indicates that cleaning is in progress. Philips does not use a sound signal. The light lid engages with a full click when pressed down. Very good: The UV-C LEDs are only active when the lid is firmly closed and switch off immediately when it is lifted. According to Signify, an additional layer of plastic around the lid prevents light from escaping. With success: we did not see light from the interior in the test. One round is over after 8 minutes.
