Bought it for a senior who is living in an apartment with a wall heater which emits stale unfiltered air. This handles that issue by delivering filtered air, hot or cold. Easy to set up and connect to the app. Love that it can be monitored and controlled remotely to check on temperature and air quality and use of the heat. You can adjust the arc of turning side to side and many other settings. Downside is that due to some government regulation, it said you cannot control the heat remotely. Bummer. I can see how that could be a safety problem so oh well. I think DYSON should make that limitation clear in the description because it would be a deal breaker for some people. Otherwise, a top performer so far.
