Frequently asked
How do I find the model name of my air purifier?
It is on the label on the device and in the Xiaomi Home app under the device information.
How often do I need to change the filter?
Usually every 6–12 months. For the antibacterial filter and the Formaldehyde Filter S1 it is 3–6 months, for the Elite 10–14 months. The actual lifespan depends on use and air quality. You can see the filter status in the Xiaomi Home app.
Standard filter or Filter Pro for the 4 Lite?
Both fit the Smart Air Purifier 4 Lite. The Pro is also anti-bacterial and anti-mold.
I cannot find the original filter for my Smart Air Purifier 4 any more. What now?
The original filter (SKU BHR5120GL) is discontinued (EOL). The HEPA filter for Mijia Smart Air Purifier 6 and Xiaomi Air Purifier 4 fits as a replacement. It is intended for both devices.
There is no filter for my Mi Air Purifier Pro H any more. What can I do?
The original filter is discontinued (EOL) and can no longer be ordered. Third-party filters may still be available on the Swiss market. We do not sell or test them and cannot give any information about them.
My filter is not listed or is sold out. Can you order it?
No. Our range is the items in the online shop. We cannot give a date for when it will be back in stock because it depends on deliveries from Xiaomi.
