A backpack blower includes a motorized blower unit driven by an engine mounted to a frame having straps to be supported by a user's shoulders and having an air discharge pipe with openings which allow a portion of the air discharge to blow out onto a wearer's neck, head, and/or body. A deflector can further be added to direct the air discharge and the deflector can be adjustable. One or both of the deflector and openings can include a control device which allows for flow through the opening or deflector to be stopped or the volumetric flow rate of air passing there-through can be adjusted.

A solid fragrance carrier comprising a fragrance-containing polymeric matrix adhesively bonded to a filter or filter bag for filtering an air stream in a vacuum cleaner for providing a fragranced scent to air exhausted from the vacuum cleaner.
