Question about Xiaomi MI Air Purifier Pro H

Yes, it works without the internet. The Mi Air Purifier Pro is controlled by the button on the top of the device as soon as it is switched on. The button switches between the different modes. The display at the front then shows which mode is currently in operation.

The Internet functionality is only additional, you can then control the Air Purifier Pro. But it does not have to be set up in the WLAN for it to fulfil its function. The laser sensor built into the device detects polluted air and switches to a higher cleaning level as long as necessary and will then select a lower cleaning level again.

Another tip: the air filters do not need to be replaced when the unit asks for them. Simply vacuum up superficial dust with the hoover, reinsert the filter and perform a filter reset. This saves a lot of money, because these filters are intended for Asian countries, where the air is incredibly dirty. For us, a 180-day filter easily lasts a year or more.
