Review on Xiaomi Mi Air Purifier 2S CN Air Purifier, white by Czesawa Wlazo ᠌

The first thing you encounter is super buggy software, connecting this device to wifi and phone is a whole story. But even after connecting, the application continues to fail, but this is more a matter of the Chinese software itself and its localization (work in the 2022). As they say here, you need to choose the region of China, and there are features on how to connect to the device, for example, if via the Internet without connecting to a router, or if the phone is in the same Wi-Fi network. It works better for me over the Internet than through a router. The noise from the fan (in the quietest night mode) is still there, it can be compared with a laptop fan, the farther, the noisier it becomes, it is logical that dust gradually gets into the mechanisms. The next key question is what do you expect from this device. It practically does not affect the amount of dust, after a week a standard layer of dust covers objects, even those that are next to the device. Wet cleaning will be done as before with the same frequency. The software has the ability to configure it to automatically turn on if the level of pollution in the room exceeds a certain level. Here, either the soft / sensor is buggy, or it is specially made that with a certain frequency it activates itself (the condition worked), the indicator shows an increased value for the first minute, and then drops to the standard one (in my case, around 003-005). One gets the feeling that it is tuned in order to develop a filter resource. The filters cost about 3k a piece, the device has an RFID tag that will force you to replace the filter when a certain number of days have passed. That is about a couple of times a year.
