4. Operation
Once installed, the KLUfo MJXFJ-150-A1 Composite Filter operates passively as part of your Xiaomi Mijia Fresh Air System A1. The air system will draw air through the filter, which then removes particles and odors. The integrated RFID chip allows the air system to monitor the filter's usage and estimate its remaining lifespan.
Ensure your air system is set to the appropriate operating mode (e.g., automatic, manual fan speed) to optimize air purification based on your environment's needs.
5. Maintenance
Regular filter replacement is essential to maintain optimal air purification performance and extend the lifespan of your Xiaomi Mijia Fresh Air System A1.
- Filter Life: The lifespan of the KLUfo MJXFJ-150-A1 filter varies depending on air quality, usage frequency, and operating environment. Your Xiaomi Mijia Fresh Air System A1 will typically indicate when a replacement is needed, often through an indicator light or an alert in the companion app.
- Replacement Frequency: As a general guideline, it is recommended to replace the filter every 6 to 12 months. However, in environments with high pollution levels or continuous use, more frequent replacement may be necessary.
- Disposal: Used filters should be disposed of responsibly according to local waste disposal guidelines.
