I have noticed how a sealed house seems to collect the air quality of the previous days. Maybe the furnace system pools the pollutants or it is the lack of ventilation that causes a build-up of smell. But maybe our lungs also help quite a bit with the cleaning of an occupied house. It makes sense that lungs help clean the air because they trap pollutants.

Smoke will stay in a sealed, unoccupied room for a long time until people actually enter and breathe the air. Then our lungs start removing harmful pollutants and start cleaning the air. So our lungs are natural filters. But imagine the cost of cleaning the air this way as lungs cannot be easily replaced.

One could calculate how much air pollution the citizens of Prince George filter out of the air. We do our share of helping to clean the air. Of course, lungs cannot be changed as regularly or as conveniently as we may wish. And I do not know of many who would approve of this method of cleaning the air of Prince George.
