Anyone in Wi-Fi range can exploit the device. The sensors of the air purifier can be used for spying, and the device could also serve as a hopping point for exploiting other devices in your home.

To be able to... know if your target's house has a lot of pollutants? Is particularly warm? There is practically no useful information that can't be gleamed by just looking through their windows, blinds and all.

It's not connected to your home network, that's the whole reason for the hotspot existing. How, exactly, could it be used as a hopping off point, except to other devices with hotspots that... can just be exploited in the first place.
You're lacking in imagination, and maybe the conceptual idea of "sensor fusion". Multiple seemingly innocuous data streams in isolation can be combined to create sensors you wouldn't have imagined
At a guess; if able to monitor over a period of time (e.g. pick up data from a parked car), a potential burglar can see when there is activity and figure what times of the day house occupants are normally at home.
More subtle; the burglar could just park up and go off for a few hours and gather the data they need - no need for a suspicious camera pointing out of the car to monitor patterns.
If the burglar only takes a 30 second look before breaking in, residents could be home but away from a window, with this the burglar can more confidently know when is a good time to break in, without exposing themselves to the same risk that looking around the house brings.

I have plenty of imagination. I also am practical and realize how illogical the argument of “sensor fusion” is to do something you can just use your eyes for.
Nobody is going to go out of their way to do this when KISS methods already exist and y’all don’t seem to understand practicality if you don’t see that.
