It's pretty common in my city that all of the apartment buildings are ventilated through the exhaust fans in the bathrooms, i.e., the bathrooms exhaust air continuously and fresh air is expected to come into the unit from the exterior wall and through cracks in the exterior windows. This is what we have been doing as well for a few years but it makes me uneasy every time we do this.
Can 40 to 50 CFM really come through cracks in the exterior wall? Part of me thinks that the fans are just running ragged due to the negative pressure. Please let me know your thoughts and if you've had experience with this.
