Apparatus and method for supplementary cleaning of cotton fibers employing a housing having an interior dividing screen separating the housing into two chambers and a fan adapted to entrain the fibers in a moving airstream and direct them into the housing against the screen for passage of the airstream and debris through the screen into one chamber and retention of the fiber in the other chamber. Reciprocably pivoting vanes divert the airstream back and forth across the screen to prevent accumulation of the fiber on the wall under the force of the airstream and to permit the fiber to fall from the wall after impact thereagainst. Alternatively, the conveying conduit may be movably mounted for side-to-side emission of the airstream into the housing. Ion emitters may be located at strategic locations to eliminate electrical attractive forces between the fibers and the debris.
