I have 2 window air conditioners in my house. None of them seem to have a setting to bring in (a little bit of?) fresh air. When we cook, the house becomes a bit smokey. Also, the vapors of freshly cut onion can can be felt even in the rooms adjacent to the kitchen. On cool days, I open the windows and place a fan near a window to drive out air from the house (and get in fresh air from other windows). But what is the best solution on hot&humid days when turning off the AC and using the above method is not an option?
