Air purifier: where to put it and how often to change the filter

An air purifier will not help much if it sits in a corner behind the sofa. A few simple rules improve results at no cost.

Where to put it

In the room where you spend the most time, usually the bedroom or living room. Leave free space around it so it can draw in and push out air without obstacles.

How often to change the filter

Follow the Mi Home app and its filter life indicator. In dusty rooms or when cooking, the filter wears out sooner.

Auto mode

Thanks to the air quality sensor, the purifier adjusts its power by itself. At night, quiet mode is often best.
