What is a good method to improve overall indoor air quality?

Increasing ventilation is an effective method to improve overall indoor air quality. Proper ventilation helps to dilute indoor air pollutants, bringing in fresh outdoor air while expelling stale, contaminated air. This is particularly important in spaces where contaminants like volatile organic compounds (VOCs), carbon dioxide, and other particulates can accumulate. By enhancing airflow, it reduces the concentration of these pollutants, contributing to a healthier indoor environment.

In contrast, reducing ventilation would likely allow pollutant levels to rise, leading to poorer air quality. Relying solely on air fresheners can mask odors but does not eliminate the underlying sources of pollution. Additionally, using air conditioning alone does not necessarily enhance air quality unless it is equipped with effective filtration and is combined with adequate ventilation practices.
