Does the filter of the Xiaomi Smart Pet Care Air Purifier have an expiration date?

The filter of the Xiaomi Smart Pet Care Air Purifier does not have a specific expiration date. However, it is an accessory that should be kept unopened and unused to maintain its performance. As long as the filter remains sealed in its original packaging, its storage time will not affect its effectiveness. However, once the filter has been opened and used, its lifespan will depend on factors such as the usage frequency and air quality. To monitor when it's time for a replacement, you can refer to the device’s display screen or check the Mi Home/Xiaomi Home APP, which will provide expiration or replacement reminders based on the filter's usage.
For optimal performance, it is recommended to replace the filter every 6 to 12 months or as indicated by the purifier’s reminders. Proper maintenance ensures that the air purifier continues to provide clean and healthy air.
