Make air sampling fast and simple with preassembled, preloaded filter cassettes. Cassettes come preloaded with PVC membrane filter which is used to sample for airborne metals, silica, or dust. Select from 25-mm or 37-mm diameter membrane filters and two- or three-piece housing to meet NIOSH, OSHA, and EPA standards. Cassettes are preloaded in an ISO 9001:2015-certified facility ensuring high quality control standards.

Clear styrene housing provides excellent visibility, allowing you to confirm that the filter media is installed and working properly. Models with clear shrink band provide added leak protection. To ensure tamper resistance, select model with security band that goes over the end plugs.
