A filter of a structure to remove extremely fine solid particulate matter suspended and carried by flowing compressed air which air stream has been previously treated so that it is essentially dry and liquid free. The filter is designed to operate efficiently on a continuous basis without prematurely clogging and is capable of removing all solid particulates larger than 1 micron mean diameter (0.00004 inches mean diameter) and a substantial number of particles of submicronic size.
