Aside from mold, what is a common contaminant found in indoor settings?

Organic dust is a prevalent contaminant found in indoor environments due to its composition, which includes a variety of biological materials. This can encompass dust mites, pollen, mold spores, plant fibers, and human skin flakes. Organic dust can contribute to poor indoor air quality and may exacerbate allergic reactions or respiratory issues in sensitive individuals.

While pollen and pet dander are also common indoor contaminants, their presence often fluctuates based on the season or household pets. Metal dust may be relevant in specific industrial settings or construction sites but is less common in residential indoor air environments. Thus, organic dust serves as a more inclusive category that encompasses a variety of materials that can be found almost anywhere indoors, making it a significant consideration in evaluating indoor air quality.
