What are common sources of dust particles found indoors?

Common sources of dust particles found indoors primarily relate to the accumulation of materials and neglect in maintaining cleanliness. Poor housekeeping is a significant contributor to indoor dust because it allows dust to build up from various sources such as skin cells, hair, textile fibers, and dirt that enters from outside. When surfaces are not regularly cleaned, these particles can accumulate and become airborne, especially when disturbed by movement within the space.

While outdoor pollutants can introduce dust into the indoor environment, they are not a direct source of dust accumulation within the indoor space itself. Fresh air circulation may help dilute indoor dust levels, and efficient vacuum cleaners can assist in removing dust rather than being a source of it. It is the regular maintenance and cleanliness that play a crucial role in minimizing the presence of dust particles indoors, which is why poor housekeeping stands out as the most common source.
