What is the first priority for improving air quality?

The first priority for improving air quality is removing the contaminant when feasible. This approach directly addresses the source of poor air quality. By identifying and eliminating pollutants, whether they are harmful particles, chemicals, or biological contaminants, a significant improvement in air quality can be achieved.

When the contaminant is removed, the air will naturally improve without relying solely on secondary measures. While airing out the space can help by bringing in fresh air, it does not eliminate existing indoor pollutants. Similarly, installing air purifiers can be beneficial, but they serve more as a mitigation tactic rather than a fundamental solution. Adding indoor plants can also contribute to improved air quality but is much less effective at directly removing significant sources of contaminants compared to addressing the source itself.

Thus, prioritizing the removal of contaminants ensures the most effective and immediate improvement to indoor air quality.
