BioIdea has EMS AllergencoD spore trap air cassettes to supply,  and vacuum pump, flowmeter, cassette adaptor, timer, Anderson Impactor to rent.
Be careful if you never did sampling before. Very importantly, if you are sampling using air cassettes (which are expensive), follow each manufacturer's instruction!  BioIdea is not liable for any mistake you make. 
Make sure the air-flow direction through cassettes or E6 Microbial Impactor (Anderson Impactor) is correct! Overloading air cassettes will render reading impossible, wasting expensive air cassettes. Overloading molds or bacteria onto medium plates in Anderson Impactor will make reading inaccurate.
A. Sample your air with Air-Cassette

Forair cassettes such as EMS AllergencoD and Zefon AOC, with a vacuum pump of flow-rate of 15 L/Min, sample very clean indoor air for 10 min, dirty air for 2-3 min, very dirty air in such as demolition site, moldy basement etc, for only 1 minute. For wall check, time is 0.5 min!
