How to collect an environmental dust sample: this article describes how to build (well basically just buy) inexpensive equipment & materials to perform your own dust or particle sampling for qualitative analysis. Taking a look at dust or particles collected from a suspect surface, building area, furnishings, even insulation, can be quite helpful in detecting the presence of high levels of problem particles such as mold from a nearby problem mold reservoir, animal allergens (hair, dander), insect fragments, fiberglass or other insulation particles, or other materials. Here we explain why qualitative assessment (what are the dominant particles) is often quite sufficient to screen building areas or furnishings for certain contaminants. We further argue that quantitative analysis (how many particles of a given sort are present per cubic meter of air or per square foot of surface area) are often seriously inaccurate and can be quite misleading.
