In the past few months, we have covered a bunch of personal and large air purifiers. The Samsung Air Purifier [AX7500] is an air purifier designed for smart homes. It offers WiFi control, so users can turn it on/off from the app. There is also a real-time filter monitor that shows when to replace filters.
The device has a smart display to show the level of dust and gas. It also comes with a 5 layer purification system. Samsung has more on this smart air conditioner here.
