The concept described here is what us homebuilders call “make up air.” In a tight envelope, when you need to exhaust air, you have to forcibly introduce fresh air to make up the difference. Otherwise your envelope (home) will sit in a vacuum and air won’t move anywhere.
Usually, there is only one window in a bathroom. If you have a fan, turn it on and open the window and it should disappate quickly. If you only have the window and no fan, punch a hole through the drywall to the next room, preferably close to the baseboard for optimal airflow. I assume you are at your “special friend’s house” and trying to hook up. Wait a few minutes and it should clear. Hope this helps!




For your interest in cultural history, I think that Budapest would win, as it has been a crossroads for centuries. For environmental studies, Iceland would win hands down. They are global leaders in that field.
Something that has not been mentioned yet is that Budapest is rather large, with a metropolitan population of over 2 million. The entire country of Iceland has under 400K people. Iceland is remote and feels remote. To me, that’s perfect. Your results may vary.
