How can improper ventilation affect indoor air quality?

Improper ventilation significantly impacts indoor air quality by trapping odors and pollutants within a space. When ventilation is inadequate, stale air is not properly exchanged with fresh outdoor air. This means that harmful substances, such as volatile organic compounds (VOCs), dust, mold spores, and other pollutants produced from indoor activities (like cooking or cleaning) accumulate over time.

This accumulation can lead to poor air quality, which can cause discomfort, health issues, and exacerbate allergies or asthma symptoms. Proper ventilation helps dilute and remove these contaminants, improving the overall indoor air quality. Therefore, it's crucial to maintain good ventilation practices to ensure that air circulation effectively minimizes the concentration of indoor pollutants and odors.
