The Best Smart Fan: Blueair Pure Fan Auto
The newest model of the Blueair Pure Fan Auto ($300) does the work for you. The smart device can actually sense the air quality, and work at a level to improve it in your room, while keeping you cool. It also comes with pre-filters that are washable, to help catch larger particles. The pre-filters are avaliable in five colors, so you can choose one that'll match your style.
