For peak performance, it's generally recommended to replace the filter in your Smartmi E1 Air Purifier every 3 to 6 months. Your device will also notify you via the app when a filter change is needed. Timely filter replacement is vital for maintaining the air purifier's effectiveness and ensuring clean air. To guarantee optimal performance and longevity, always purchase genuine, compatible filters directly from official Smartmi channels.
