ABSTRACT:
A forced air handling system filter is provided including an inwardly opening, channel-shaped peripheral frame from which corresponding peripheral portions of a panel-like filter batt is supported and an elongated bar of scented material is provided and stationarily supported within a pocket of the frame opening inwardly of the inner periphery thereof. The bar includes a scent impervious cover completely enclosing the bar and one longitudinal edge of the bar projects outwardly of the aforementioned pocket toward the remote side of the frame and that portion of the cover disposed over the bar marginal portion includes a tear strip extending longitudinally thereof. The tear strip is adjustably tearable from the remainder of the cover to expose a corresponding portion of the bar for scent release therefrom.
