It doesn't do any of those things, it just senses AQI, PM 2.5 and puts it on the screen. My experience with the devices that attempt to do the things you want is that they suck. They do each of those things poorly and their basic detection functionality (most important feature) is also bad. (The reddit thread I linked to has details). If a device existed that did those things and was actually good I'd recommend it. As it is, everything in the market is awful. At least these Temtops have the basic functionality down and do that part really well.
