Anti Radiation and Waterproof
You and your laptop need to have a break.
Keep away from electromagnetic radiation, and enjoy better sleep all night.
The case lining is made 100% silver fiber, which can be damaged by frequent or improper washing.
Little or not washing is recommended to maintain the shielding performance of the item.
If washing please follow these instruction:
- Wipe clean with a damp cloth
- Do not use bleach
- Air dry in shaded or indirect light
- Iron in a low temperature
- Do not machine wash or dry clean
Please refer to the attenuation measurement below db/%
- 10dB = 90%
- 20dB = 99%
- 30dB = 99.9%
- 40dB = 99.99%
- 50dB = 99.999%
- 60dB = 99.9999%
Because of different phone using environment, we can’t make sure that the phone in the case can’t be connected completely.
Also from expert’s viewpoint, it’s not right and not scientific to take this method as a testing shielding performance standard.
This case just can shield phone itself radiation completely.
