What is a critical consideration when improving indoor air quality?

Ensuring balanced ventilation is essential for improving indoor air quality because it helps maintain an appropriate exchange of indoor and outdoor air. Proper ventilation is critical for diluting indoor pollutants, such as volatile organic compounds (VOCs), allergens, and other harmful particulates, which can negatively impact health. Balanced ventilation takes into account the supply and exhaust of air, ensuring that air is neither over-pressurized nor under-pressurized, which can lead to drafts, humidity issues, or insufficient removal of contaminants.

Moreover, balanced ventilation systems typically incorporate filters that clean incoming air, further enhancing air quality. This balance prevents the accumulation of moisture and pollutants, promoting a healthier living environment.

In contrast, maximizing the number of windows may increase airflow, but it does not guarantee that the air entering is clean or that it is properly regulated. Using heavy furniture to absorb odors could be ineffective if the source of the odors is not addressed or if the furniture itself emits VOCs. Controlling thermostat settings can influence temperature, but it does not directly contribute to the effectiveness of air quality management without a well-balanced ventilation system in place.
