Which of the following is a strategy aimed at improving indoor air quality?

1. Maximizing indoor humidity

2. Using natural ventilation

3. Eliminating all cleaning products

4. Reducing outdoor air ventilation

The correct answer is: Using natural ventilation

Using natural ventilation is a highly effective strategy for improving indoor air quality. Natural ventilation relies on the movement of outdoor air into a building through windows, vents, and other openings. This process can dilute indoor pollutants, bring in fresh air, and help maintain a healthy indoor environment by removing stale air. By incorporating natural ventilation into building design, occupants benefit from increased air circulation, which can help decrease the concentration of indoor air contaminants and enhance overall comfort. This is particularly important in spaces where people spend significant amounts of time, as improved air quality can lead to better health and productivity outcomes. The other strategies mentioned do not contribute positively to indoor air quality. For instance, maximizing indoor humidity can create a conducive environment for mold growth and increase discomfort. Eliminating all cleaning products might not be practical or effective, as some level of cleaning is necessary to maintain hygiene. Reducing outdoor air ventilation can lead to the buildup of pollutants and decreased air quality.
