This portable smoke-free 15” Black & Decker smokeless wood-burning fire pit is the brand-new way to enjoy a wood-burning fire, without the smoke odor saturating your clothing. The advanced design uses intake vents in the double-insulated fire pit walls and base to super-heat the air and then feed it back into the fire bowl. This new technology removes up to 70% of the particulates in the smoke when the wood level is kept below the top edge.
