Multi Layer Filtering Technology
Flexible, tear resistant  Synthetic Dust Bags expand as you clean. The Multi-layer construction allows air to flow through, yet traps dust, and fine particles. While paper dust bags cause suction loss when only half full. Synthetic Dust Bags last twice as long, ensuring full-power suction until the bag is completely filled.
