A filter vent system and method for separating entrained airborne particulate matter from the conveying fluid is disclosed, particularly as it relates to filling a storage vessel. The filter system employs a simplified, yet more efficient filter cleaning arrangement, in which the entire clean air plenum on the downstream side of a filter array of one or more filter units is periodically pulsed with a large burst or pulse of relatively high pressure air from a single source which rapidly raises the plenum pressure to, in turn, produce a temporary pulsed flow reversal in the filter units which blasts through the filter pores to displace particulate matter collected on the upstream side of all of the filter units alike thereby cleaning or re-generating the filter surfaces.
