Even the best air purifier can’t do much without airflow. So ideally, you won’t shove your air purifier off in a corner right next to a wall.

Most cylindrical models have intake vents all around the outside, but box models may have them on just one side, so make sure you point the vents outwards towards the center of the room. Smaller air purifiers work better if they’re up off the ground by a couple feet, such as on top of a stool or end table.
