Why are there black powder particles falling out of the newly unpacked Mijia Smart Air Purifier Max Filter?
If there are black powder particles falling out of the newly unpacked Mijia Smart Air Purifier Max Filter, please refer to the following information:
1. During transportation, the filter can experience slight powder shedding due to vibration and friction. This is normal.
2. If you find black powder on the filter after opening the device or the new filter packaging, it can be activated carbon powder.
3. Please wipe it clean with a damp soft cloth before re-installing. After the device is running, there will be no further continuous powder shedding. Please use it with confidence.
4. Make sure the filter is installed correctly and fully seated in its slot. Improper installation may cause residual particles to fall.
5. Avoid shaking or tipping the filter excessively when handling it, as this can dislodge more powder.
6. If you notice unusually large amounts of powder or continuous shedding after the device is running, contact the after-sales service center for inspection.
