Building scientist and writer Jeffrey C. May likens air circulation in a home to breathing. “A house ‘breathes’ as air flows from the outside to the inside,” he writes.

May gives several examples of designs and appliances that are detrimental to a home’s air quality, and possibly detrimental to the home’s occupants.
