Air Vent Pipes
These are the air vent pipes outside of the garage. These vent pipes are about 4 inches in diameter, they have large cartridge type air filters underneath the cans on top of the pipes. The tops of the pipes are 5 to 7 feet off of the ground. I think the intent of the difference in height is to allow induced air flow (warmer air going up the taller stack while cooler air is drawn in shorter stack) but I think the pipes are too small for that to actually work. There is also a vent pipe through the ceiling of the entry room that goes up through the roof of the garage.
