Installation

No tools or special expertise required.

1. Turn off your Xiaomi Smart Air Purifier 4 Compact and set it to standby.
2. Remove the existing filter by turning it counterclockwise to unlock.
3. Align the new filter's unlocking mark with the alignment mark on the purifier.
4. Turn the filter clockwise to lock it into place.
5. Reset the filter life indicator per your unit's manual, if needed.

Filtration and Maintenance

• Pre-filter layer: Blocks large particles such as hair, dust, and debris from entering the purifier
• True HEPA layer: Captures up to 99.97% of airborne particles as small as 0.3 microns
• Activated carbon layer: Helps reduce household odors

Tip: The activated carbon layer may give off odors after prolonged use. Placing the filter in a well-lit, ventilated area for a period can help refresh the carbon's adsorption capacity.

For best results, replace approximately every 6 months, depending on usage and indoor air quality.
