Abstract

An external filter assembly adapted for modifying a suction cleaning device to sample relatively small particles from various surfaces and/or the ambient air, includes a housing having a first open end, a second open end and a throughbore between the first and second open ends, a filter adapted for capturing particles with particle sizes greater than 0.1 micrometer, the filter being mounted on and enclosing the first open end, and means for securely retaining the second open end of the housing on an exhaust port of the suction cleaning device in communication with the housing throughbore.
