Which strategy is most effective for reducing indoor air pollutants in homes?

Explanation:
Ventilation reduces indoor air pollutants by diluting and removing contaminated air with fresh outdoor air. Opening windows or using exhaust fans and a proper ventilation system increases air exchange, lowering concentrations from cooking, cleaning products, and building materials. In contrast, increasing VOC cleaners or using perfumed air fresheners adds pollutants to the air, and keeping windows closed reduces exchange, allowing pollutants to accumulate. Because diluting and expelling indoor contaminants is the most effective way to improve air quality, adequate ventilation stands out as the best strategy.
