An environmental sampling system and method that collects biological contaminates in a removable cassette device via a sample capture media, such as a filter. The cassette device which is designed to specifically cause mixing of the air stream in a manner to get even distribution of the airborne particulates on the filter media has affixed thereto a data storage unit for storing other environmental parameters sensed and measured by the system in addition to the IAQ questionnaire information inputted by the investigator. After the sample period is complete, the system can be re-deployed in the field or environment by simply replacing the removable cassette device having the data storage unit. The collected biological contaminates in a removable cassette device and stored data in the affixed data storage unit are sent to a laboratory for analysis. The environmental sampling system may be operated independently of the removable cassette device to obtain and data log physical environmental data such as temperature, relative humidity, wind velocities, pressure differentials, and particulate counts.
