The basic Mold air quality test kit comes with 3 air sampling cassettes. To collect additional air samples, then buy additional air sampling cassettes. Air sampling cassettes are used together with the air sampling pump to collect air. The cassettes collect both viable and non-viable particulate such as mold spores, pollen, insect parts, skin cell fragments, fibers (fiberglass, cellulose, etc.) and inorganic particles. These cassettes are specifically designed for the rapid collection and quantitative and qualitative analysis of a wide range of airborne particles including mold spores. The analysis of the air samples is performed by an experienced microbiologist.
These cassettes are sold as additional sample package when you buy the mold air quality test kit. The cost is $86 which includes the lab analysis and the cassette. The mold air quality test kit consists of the air sampling pump and 3 cassettes. If you need to take more than 3 air samples, then buy additional air sampling cassette packages.
