Abstract
Vacuum cleaner canisters and vacuum cleaner filter bags are provided with weir members disposed in the path of particle laden air flowing through the vacuum cleaner. The particle laden air flows across the top and/or side edges of the weir members creating a pressure drop thereacross and an area of low pressure on the downstream sides of the weir members whereby particles in the airstream are influenced to drop out of the airstream and into the low pressure areas.
