Filter Cassette

A Filter Cassette is a compact, enclosed holder used in air sampling to capture pollutants, particulates, or aerosols for analysis. It is a key tool in environmental and occupational health assessments. These cassettes contain a pre-weighed filter, usually made of materials like PVC or mixed cellulose esters, depending on the target analyte. Air is drawn through the filter, trapping particles. After sampling, the cassette is sealed and sent to a lab for gravimetric analysis or substance identification. This method is crucial for monitoring air quality, ensuring compliance with safety standards, and protecting human health in various settings.
