PB 3334166 Synthetic Panel Air Filter for Minuteman Power Boss Sweepers and Scrubbers. An upgraded spun-bond polypropylene, water-washable hopper air filter. Synthetic poly filters have the advantage over standard cellulose filters in that they can be removed and washed with water (be sure to fully dry poly filters before re-installing). Measures 15 x 30" and includes poron or urethane gasket material. Fits Minuteman Power Boss models including AM7D-III, Armadillo 6X, SW/6X, SW/6XV (Badger), SW/62 Deluxe, SW/62E, SW/62IC, SW/72, and SW/72 Deluxe. Most models require one filter. There was a design change on some of the SW/72 models. Please check your model before ordering to see if it requires a 15 x 30" panel air filter. Replaces Minuteman Power Boss 3334166.
