A kitchen chimney, also known as a range hood or exhaust hood, is a ventilation device installed above a stove or cooktop in a kitchen. Its primary function is to remove airborne grease, smoke, heat, and cooking odors from the air in the kitchen.

Kitchen chimneys typically consist of a canopy or hood that captures the airborne particles, a fan or blower that creates airflow to draw the air through filters, and a duct system that vents the air to the outside of the building. Some models also include additional features such as lights to illuminate the cooking area or variable speed controls to adjust the airflow.

There are various types of kitchen chimneys available, including wall-mounted chimneys, island chimneys (suspended from the ceiling over a kitchen island), and built-in or under-cabinet chimneys. The choice of chimney depends on factors such as kitchen layout, cooking habits, and aesthetic preferences.
