FAQs
How often should I replace the filter?
It is recommended to replace the filter every 6 to 12 months depending on the air quality in your home and how frequently you use the purifier.
Can I wash this filter with water?
No, this filter should not be washed. Water will damage the electrostatic charge and the high-efficiency media, rendering it ineffective.
Does this filter work with older Xiaomi air purifier models?
This filter is designed specifically for the Xiaomi Smart Air Purifier 4. Always check your specific model's manual before purchasing to ensure compatibility.
How does this differ from a standard HEPA filter?
Xiaomi's high-efficiency filter uses a combination of electrostatic charge and mechanical filtration, allowing for better airflow, lower noise, and lower power consumption compared to traditional HEPA filters.
Will the app notify me when to buy a new filter?
Yes, the Mi Home/Xiaomi Home app tracks your usage and will send a notification when the filter reaches the end of its effective lifespan.
Troubleshooting
The app is not showing the correct filter usage percentage.
Ensure your air purifier is connected to a stable Wi-Fi network and that the device is synced with the latest version of the Mi Home app.
The air purifier emits an unusual odor.
The activated carbon layer may be saturated. Check the filter life in the app; if it is near the end of its life, replace the filter.
Airflow seems significantly reduced.
Check the exterior primary filter mesh for a thick layer of dust or hair. Use a soft brush or a vacuum hose on low suction to gently clean the outside.

Setup, Compatibility & Care
To install the filter, power off your Xiaomi Smart Air Purifier 4, open the filter compartment, and remove the old unit. Insert the new filter, ensuring the dimensions (210mm x 210mm x 293mm) are seated correctly in the housing. Once installed, reset the filter life timer within the Mi Home app. For maintenance, you may gently brush off visible dust from the primary filter layer periodically, but avoid washing the filter with water or chemicals, as this will destroy the specialized filtration media. Always keep the air intake clear of obstructions to maximize the filter's service life.
