Household Dust

Cleaning dust can reduce short-term exposure but does not remove the hidden mold source. Dust testing is framed as a better long-term exposure record than a short air sample. Household dust is presented as a major pathway for exposure to mold-related contaminants. Ordinary movement can push contaminated dust back into the breathing zone. Household dust is described as a reservoir for mold spores, mold fragments, bacterial fragments, and other pollutants. Cleaning dust with HEPA vacuuming, microfiber wiping, and wet mopping is treated as central after mold contamination. Dust can become airborne during routine activity and be inhaled repeatedly. Dust can repeatedly expose occupants even when the original source remains hidden. MSQPCR is described as a DNA-based dust testing method for identifying mold and bacteria.
