Should you run an air purifier with the windows open?

You can run your air purifier with the windows open if you’d like. It’ll improve your indoor ventilation. Just don’t put the air purifier too close to your window.

I would crack open a window, put your air purifier on a counter, and run it on Auto. Run it for a few days and see if you notice any difference in your air. If not, try moving it to the floor or manually controlling the purifier.
