I'm stumped at what to get for our 400 square foot balcony. It has a 14 foot high ceiling, and three of the four walls were formerly just screens but we've added windows. We'll have PTAC units providing heat and AC (we're in Missouri, USA). When it is very hot or very cold, we'll want to keep windows closed but will need to purify the air due to the cigar and cigarette smokers in the family. What do you recommend? When we purchase a unit (or more), do we put them next to where the smokers will be? Not necessarily tied to a tight budget.
