Setting it to let in outside air will let fresh air with oxygen in through the carbon activated filter. This filtered air should be much better for you than opening the window and letting unfiltered air in.

Dont know how it can become stuffy when you let fresh air in. Sure you arent using the controls backwards ?

I just usually leave it in Auto so the vents close if there is something nasty like diesel fumes from the cart in front in the air. Else they are open

..interesting.. for some reason my E92 does not seem to be triggered to recirculate when encountering diesel fumes etc.... not sure how that particulate sensor works.. if I have one ~Frost
