How to check the filter element’s lifespan of the Mijia Air Conditioner Pro Eco 3.5 kW?

The Mijia Air Conditioner Pro Eco 3.5 kW does not have a filter element. Instead, it comes equipped with a built-in washable filter screen, which is designed to be durable, long-lasting, and resistant to damage under normal use.
To help maintain optimal performance, the Mi Home/Xiaomi Home APP offers filter clogging alerts, reminding you when it’s time to clean the filter. Regular cleaning ensures efficient airflow, better cooling, and improved air quality.
To clean the filter of the air conditioner, simply open the clips at both ends to remove the filter, clean it with a vacuum or mild soap and water, let it dry completely, and reinstall it securely.
