Which of the following enhanced IAQ strategies is not applicable for naturally ventilated spaces?

1. Filtration

2. Natural air flow management

3. Regular cleaning procedures

4. Indoor plant integration

The correct answer is: Filtration

Filtration, while an important strategy for enhancing indoor air quality (IAQ), is primarily associated with mechanically ventilated spaces where air filtration systems are installed to remove contaminants from recirculated air. In naturally ventilated spaces, air movement relies on the natural flow of outdoor air, which typically does not include mechanical systems that require filters for air purification. In contrast, natural airflow management, regular cleaning procedures, and indoor plant integration are all strategies that can be effectively implemented in naturally ventilated environments. Natural airflow management involves ensuring that windows and openings are used strategically to enhance ventilation and reduce pollutants. Regular cleaning helps maintain a clean environment, reducing dust and allergens. Indoor plants can improve IAQ by taking up pollutants and releasing oxygen, making them a beneficial addition to spaces that utilize natural ventilation. Thus, filtration is not applicable in naturally ventilated spaces since these spaces do not have mechanical air systems requiring filtration to address indoor air pollutants.
