There are many factors that you must consider before buying a Kitchen chimney or an Exhaust fan. Both exhaust fan and kitchen chimney remove the smoke from your kitchen and vent it into the outside atmosphere.
The major difference between the way a kitchen chimney and an Exhaust fan work is the way the smoke travels. In case of the Kitchen chimney the smoke is sucked into a duct directly above the hob/stove and does not interact with any other kitchen components. But an exhaust fan pulls the smoke in one place and thus allowing the smoke to interact with other kitchen elements.
