It achieves 99.97% filtration efficiency for 0.1 to 0.3µm airborne particulates, including pollen, dust, pet dander, and smoke.
- Smart Air Quality Monitoring: An integrated PM2.5 display and infrared sensor monitor air quality in real-time, automatically adjusting fan speeds to maintain a clean and safe environment.
- Quiet Sleep Mode: Operating at an ultra-low noise level of 15dB, the Sleep Mode ensures minimal disruption for restful nights. All indicator lights turn off in this mode.

Maintenance
Filter Replacement:
For optimal performance, replace the H13 True HEPA filters every 3-6 months, depending on usage and air quality. Use only official AMEIFU replacement filters (search B0D17S8SKT on Amazon). The Filter Reminder light will illuminate when replacement is needed. After replacing, press and hold the Filter Reminder button for 3-5 seconds to reset the indicator.
Washable Pre-Filter Cleaning:
The pre-filter can be vacuumed weekly to remove larger debris like pet hair and dust. For deeper cleaning, rinse the pre-filter with water. Ensure the pre-filter is completely dry before reinstalling. Always disconnect the power before cleaning or replacing filters.
