Device and method for collecting debris entering into a duct

A collection device for collecting debris entering into an opening of a duct in a building, the collection device comprising:

• (a) a basket including an open end and a closed end and defining a chamber extending from the open end toward the closed end, the basket further including a collecting portion for receiving the debris and a fastening portion adapted to be engaged with the duct such that the collecting portion extends into the duct opening and the closed end is within the duct, the collecting portion including a material defining an annular vent adjacent an upper end of the collecting portion;
• (b) an annular damper for closing the vent and for opening the vent when air is forced through the duct, the damper being secured to an inner surface of the collecting portion and being constructed of a material that is less porous than the material of the collecting portion defining the vent;
• and
• (c) a strap associated with the basket for removing the collecting portion from the duct after a predetermined amount of the debris has been received by the collecting portion.
