Abstract
An air sampler includes an inertial impactor with a compressible porous collector that receives particles greater than a lower threshold size from an air sample. Before reaching the collector, the air sample may pass through a sorter that prevents that removes particles above an upper threshold size. A mechanism transfers the compressible porous collector and base between the air sampler and a wash position outside of the air sampler. An agitator at the wash position may agitate the compressible porous collector to remove particles therefrom. The compressor may be wetted with various substances to facilitate particle collection from the air, preservation of particles on the collector, and removal of particles from the collector.
