Collects dust & debris Before it enters your wet/dry vacuum. It improves vacuum performance and allows vacuum filters to last longer. Paid over 112$ tax included at Home Depot ( Québec ) 2025( 5 gallon bucket not included). Asking 85 $. Used for 1 project which is finished therefore no longer needed . I pass through Grenville, Gatineau, Montreal , and Laval occasionally, but live at Lac Simon in the Outaouais region.
