How does increasing ventilation affect indoor air quality?

Increasing ventilation enhances indoor air quality primarily by introducing fresh outdoor air into indoor spaces. This influx of fresh air dilutes and displaces indoor pollutants, such as volatile organic compounds (VOCs), carbon dioxide, and other contaminants that accumulate in sealed environments. Proper ventilation helps to reduce the concentration of these harmful substances, promoting healthier air for occupants.

Moreover, increased ventilation can help regulate humidity levels, preventing issues related to mold or dust mites, which thrive in damp conditions. By exchanging stale indoor air with cleaner outdoor air, ventilation plays a crucial role in maintaining a breathable and comfortable indoor environment.

While fresh air can indeed help improve indoor conditions, there could be instances where excessive ventilation might inadvertently lead to increased energy consumption or temperature fluctuations. However, these are secondary effects and do not negate the primary benefit of improved indoor air quality.
