The connectivity of the Mi Air Purifier 3H is in WiFi at 2.4GHz, while for the noise we have a maximum level of 69dB. What is at minimum speed is really imperceptible; increasing the intensity it starts to be audible and at times annoying.

The Xiaomi Mi Home app, available for Android and iOS, allows you to view the work of the air purifier in real-time, to manage the different functions and to program both on and off. There is no real report with statistics, which would have been useful to understand the state of your home and the habits on which to improve.

It should be noted that for the control of the Xiaomi Mi Air Purifier 3H it is also possible to use the voice commands present in Google Assistant and Amazon Alexa.

The maintenance of the Xiaomi Mi Air Purifier 3H is quite simple. The filters can be cleaned without any problem and have an average life of about 150 days, after which they will have to be replaced: the price of the filters is variable, depending on the type chosen and the store where you will buy them, but the figure is around 47 dollars.
