The Beam 110356 Self cleaning filter is an 11 inch weighted filter bag used to replace the permanent filter bag in a number of Beam, Honeywell, Frigidaire, Smart and Imperium central vacuum units.
While vacuuming the filter bag is drawn up inside the vacuum unit. When the vacuum unit is turned off the weighted filter bag drops down into the debris pail releasing the dust particles and debris into the dirt pail.
