One significant facet of many Indoor Air Quality (IAQ) microbial investigations is the assessment of the carpeting and dust in an occupied building. Carpet is listed as one of the nine potential sources of biological agents in an occupied space (Bioaerosols Assessment and Control, ACGIH 1999). IAQ complications may arise with poor carpet maintenance and accidental water incursions. Poor maintenance leads to an accumulation of microbial contaminants while water damage incidents provide the microbial organisms with moisture and the nutritional substrate to proliferate to problematic levels.
Micro-Vac cassettes are designed for the collection of fibers and particulate from carpets and other dusty areas. Both cassette styles use a 1" piece of tubing with a 45 degree bevel fitted to the inlet port, and come preloaded with .45µ & 5.0µ MCE filter and support pad. The 25mm Cassettes use a conductive housing. It is designed and manufactured to conform with published protocols (i.e. Millette). The 37mm cassette uses a 3 piece styrene housing and helps prevent overloading.
