You breathe crawl space air, like it or not.
As warm air rises in the home, it leaks out of the upper levels. New air must enter to replace the air that escaped. This creates suction on the lower levels to draw in replacement air.
What this ‘stack effect’ does is create an airflow in your home from bottom to top. Air from the basement or crawl space is drawn upwards into the first floor, and then to the second floor. Building scientists say that up to 50% of the air you breathe on the first floor is the air that came from the crawl space.
Therefore, whatever is in your crawl space air is in your house and affecting you and your family, whether you spend any time in your crawl space or not. If there is high humidity in the damp crawl space, there are higher than normal humidity levels upstairs. If there is mold in the crawl space, there are mold spores upstairs.
Air enters the crawl space through the open vents, and then it makes its way upstairs. Air is a very small thing and can find ways into the crawl space through holes around wires and pipes as well.
