Xiaomi Mi Air Purifier Reset: WiFi & Filter Reset

A Xiaomi air purifier can be reset. This can be useful, for example, if it keeps giving error messages or if you want to connect it to a new WiFi network. Broadly speaking, you have two types of reset options: a WiFi reset and a filter reset.
In this manual I tell you how to reset the Xiaomi air purifier and why this is very important in some cases.
Why reset a Xiaomi air purifier?
As I mentioned in the introduction, there can be several reasons to want to reset a Xiaomi air purifier. For example, you may want to connect it to a different WiFi network or you will constantly receive error messages.
The main reasons for a reset:
- Link to another WiFi network
- Constant error messages
- If the air purifier jams
- When you want to sell it (or bought it second-hand)
- After replacing the air purifier filter
There are several ways to reset the purifier. Let’s discuss both ways.
How to reset Xiaomi air purifier WiFi-network
If you want to connect a Xiaomi air purifier to a new WiFi network, you will have to reset it. This works simply:
- Turn on the air purifier
- Hold down the power button and the mode button at the same time
- After 5 seconds you will hear a notification
After a WiFi reset, you will have to add the Xiaomi air purifier to the network again via the Xiaomi app.
How to reset Xiaomi air purifier filter
A Xiaomi air purifier indicates when it is time to replace the filter. When you have installed a new air purifier filter, it is important to reset the Xiaomi Mi air purifier. That way, the air purifier knows that you have installed a new filter and you will receive a message in a while that you need to replace it. This shows a Xiaomi air purifier with a red light.

You reset a Xiaomi air purifier filter as follows:
- After replacing the filter, turn the air purifier back on
- Press and hold the Mode button (right button) for 5 seconds
- You hear three sound signals (beeps) and the air quality indicator shines green again and flashes three times
