Very good for allergy issues keeps dust levels down
Hepa filter very good for cost $ replace filters not to pricey at $40-45
Fully auto increases fan when cooking, it sounds like a turbo kits in.
Only lasts a few minutes and then fan turns back down to quietly doing its job without any noise.

3H Global - Great Product
It is very easy to setup and connect to my home 2.4 GHz Wifi without any problems. I believe you can use the air purifier without connecting to the wifi (Not sure). However the app allow you to integrate into your smart home. No, it wasn't homekit compatible, but you can integrate it into homekit via homebridge.
It is very quiet, my air conditioner is louder than the air purifier when it operate on a night mode.
It features a touch display which allow you to switch it on and off, mode, temperature, humidity, air quality and filter life span displayed.
Overall, it does what's it suppose to do.
Purchased in December 2020 at eBay for $229.
Questions & Answers
Does anyone know how long the HEPA filter last in the normal daily use (i.e. 2-4 hours per day) ?
24 hours a day will last 6 months
Can the wifi be turned off completely so it does not transmit?
If for some reason you don't want it to transmit you can just operate it manually straight out of the box. I believe you need to download the app and connect it to a 2.4 ghz WiFi modem in order for the Xiaomi Mi Air Purifier to regularly be transmitting. From memory, the air purifier may look for an app and a WiFi connection when you first plug it in. (We have always had ours connected to WiFi because we want to take advantage of all the features).
