co2 indoor air quality

CO2 Explained - Indoor Air Hygiene Institute

There are no CO2 filter mechanisms to remove CO2. Ventilation (replacing indoor air with outdoor air) is the only way to keep CO2 at acceptable levels. Ventilation can be done either naturally or mechanically. Naturally, by opening enough windows and doors to let the outdoor air flow freely through the building. Mechanically, by using an HVAC system that adds outdoor air to the circulation and removes indoor …

Read why ventilation is so important for indoor air quality

But, CO2 is a good indicator of the indoor air quality in houses, where the occupants and their activities are the main source of pollution, as CO2 is emitted by all humans while breathing and not by many other sources. However, CO2 is rarely a health issue in itself. It is nevertheless a very good indicator of human presence and the level of ventilation. Outdoor air contains approximately 400 ppm; breathing …
