Question about Xiaomi Smart air purifier 4
How often does the filter in the bedroom need to be replaced? Does the device have to be in operation all day in the bedroom or only during bedtime?
My air purifier runs all the time. The "noise" is so low that it is not disturbing. The filter has a service life of around 290 days. The replacement of the air purifier is indicated by the app.
Filter lasts a long time, but depends on the duration and intensity of use. We have the air purifier on for 2 hours before we go to bed and switch it off at night
