The indoor environment contains many different contaminants. An often overlooked contaminant, however, is dust. Dust can contain a multitude of allergens including dust mites, animal dander, and mold spores. Carpet is a major reservoir for collecting and holding dust. The ACGIH lists carpet as one of the nine potential sources of biological agents in occupied spaces. Collecting dust for lab analysis can be an important test in an IAQ assessment.
Our Recommendation:
Invest is a great air cleaner and make sure your house is positively pressurized otherwise you are doomed to fight large quantities of dust.
