Which practice can effectively help mitigate indoor air pollutants?

Minimizing the usage of pollutant-emitting products is an effective practice in mitigating indoor air pollutants because many common household items release volatile organic compounds (VOCs) and other harmful substances into the air. These products can include certain paints, cleaners, adhesives, and personal care items. By reducing the use of such products, occupants can significantly decrease the concentration of these pollutants indoors, thereby improving overall air quality.

Additionally, being mindful of the types of materials and products brought into a living or working space helps to create a healthier indoor environment. This proactive approach encourages the use of low-emission or non-toxic alternatives, further contributing to air quality improvement.

In contrast, the other options do not effectively reduce indoor air pollutants. For instance, increasing the use of air fresheners may mask odors but can actually introduce more chemicals into the air. Keeping windows closed at all times can trap pollutants indoors instead of allowing for air exchange. Lastly, using non-ventilated spaces for storage may also lead to the accumulation of pollutants or odors without addressing the air quality issues in the main living areas.
