Abstract: A method for filtering airborne particulates is described. The method includes providing an exhaust hood, and the exhaust hood defines an intake and the exhaust hood being adapted to receive airborne particulates via the intake. The method also includes conveying a portion of a filter media from a media source area to an active media area, transferring the portion of the filter media from the active media area to a media discard area, the media discard area and the media source area being disposed on substantially opposed sides of the active media area, and severing the portion of the filter media in the media discard area from a remainder of the filter media.
