Odor Filters for HLS Commercial Bins help keep a fresh and clean-smelling environment. Equipped with activated carbon, this Odor Control System with AbsorbX technology absorbs odors from rotting food and household waste as well as volatile organic compounds (VOCs) that are common, naturally occurring chemicals that can cause illness. Each filter provides up to 3 months of odor-fighting power. It fits inside the odor-filter compartment of HLS Commercial trash cans that hold 8 gallons or more.
