A wall-mounted range hood is a ventilation system attached to the wall directly above your cooking area. If you currently have a cabinet in this space above the stove, it can be removed to make room for this variety of vent hood.  

They are also known as chimney hoods because the structure used for ventilation resembles a household chimney, serving as a design element that adds a stylish and distinctive look to any kitchen space. This type of range hood vents smoke and odors from your kitchen to the outdoors through an exterior wall behind the appliance.
