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. Arm & Hammer Synthetic Dust Bags last twice as long, ensuring full-power suction until the bag is completely filled.

Odor Eliminating Vacuum bags.
