Range hoods are essential kitchen appliances designed to remove smoke, odors, grease, and heat generated during cooking. These ventilation systems mount above cooktops and ranges, drawing contaminated air through powerful blowers and either expelling it outside through ductwork or filtering it through internal systems before recirculating clean air back into the kitchen. Modern range hoods come in various configurations including wall-mounted, cabinet insert, microwave combination units, and island installations.

Kitchen ventilation systems typically measure 30 to 36 inches in width to cover standard cooktops, with commercial-grade units reaching 48 inches or more. These appliances feature stainless steel construction for durability and easy cleaning, with options for both ducted and ductless operation. Ducted models exhaust air directly outside through wall or ceiling ducts, providing superior performance for heavy cooking. Ductless units use internal filters to trap contaminants and odors before recirculating air, making them ideal for installations where external exhaust isn't possible.
