5. Maintenance

The air purifier filter is a consumable item and requires regular replacement to maintain optimal air quality and system performance. The Xiaomi Mijia A1 Fresh Fan System typically monitors filter life and will notify you when a replacement is due.

• Replacement Frequency: Filter life varies depending on usage and air quality conditions. Generally, filters should be replaced every 3-6 months. Refer to your air purifier's display or app for specific replacement indicators.
• Cleaning: The filter itself is not washable and should not be cleaned. Attempting to clean the filter can damage its structure and reduce its effectiveness.
• Disposal: Dispose of used filters according to local waste disposal regulations.

6. Troubleshooting

If you encounter issues after installing a new filter, consider the following:

• Air Quality Not Improving:
  • Ensure the filter is correctly seated and the cover is securely locked.
  • Verify that the air purifier itself is functioning properly.
  • Check if the RFID chip on the filter was recognized by the device. If not, try re-installing the filter.
  • Consider external factors affecting air quality, such as open windows or new sources of pollution.
• Filter Not Recognized (RFID Error):
  • Remove and re-insert the filter, ensuring it clicks into place.
  • Restart the air purifier.
  • If the issue persists, the RFID chip might be faulty, or the filter may not be fully compatible. Contact customer support.
• Unusual Noises:
  • Ensure the filter is installed correctly and not obstructing any moving parts.
  • Check for any foreign objects inside the air purifier.

7. User Tips

• Regular Checks: Even if your air purifier has a filter life indicator, periodically check the physical condition of the filter. A visibly dirty filter may need earlier replacement, especially in environments with high pollution or pet dander.
• Optimal Placement: Ensure your air purifier is placed in an area where it can effectively circulate air, away from walls or obstructions, to maximize filter efficiency.
• Genuine Compatibility: This filter is specifically designed for the Xiaomi Mijia A1 Fresh Fan System MJXFJ-150-A1. Using filters not designed for this model may lead to reduced performance or damage to the appliance.
