ABSTRACT:
An air cleaning method and apparatus in which air to be cleaned is drawn toward and through a filter (44, 45) along a normal path having a first component extending from a first to a second end of the filter, so as to initially collect particulate matter on the filter,in which momentary pulses of clean air are directed through the filter in a direction opposed to the normal path, to interrupt flow of the air in the normal path so as to dislodge collected particles from the filter and enable migration of the particles toward the second end of the filter, and in which the migrated particles are withdrawn, in a portion of the air, from a site (33, 115) near the second end of the filter.
