Should house be able to breathe?

Like the lungs, homes need to be able to breathe to make sure that fresh air comes in and dirty air goes out. Air indoors can build up high levels of moisture, odors, gases, dust, and other air pollutants. To keep the air safe indoors, fresh outdoor air is needed to dilute these indoor pollutants.

Can you run out of oxygen in a house?

So changes would be even smaller in most homes. Simply put, humans don't take in as much oxygen as we think we do. Based on oxygen alone, estimates are that the average person could survive in a completely sealed, airtight room for 12 full days! Running out of oxygen in a room is quite unlikely.

Do walls need to breathe?

The removal of moisture through walls is sometimes referred to as breathing. It actually takes place, depending on the material, but does not play a role in the moisture balance of a room.
