To change the air in a room, you primarily want to introduce fresh, outdoor air.
Here’s a breakdown of how to do it:
-
Open doors and windows: The most straightforward method is to open doors and windows to create airflow. According to the reference, it's best to open them as much as possible to maximize fresh air intake. Even slightly opening a window can make a difference.
-
Create cross-ventilation: If possible, open multiple doors and windows on opposite sides of the room or house. This allows for better cross-ventilation and more efficient air exchange.
In essence, you facilitate air exchange by allowing the stale indoor air to escape and fresh outdoor air to enter.
