  • Filtration

When it comes to the efficiency of filtration, the chimney does the job very well. It vents the smoke out of the kitchen after filtration, not giving any chance to spread inside the room.

On the other hand, the exhaust fan directly vents out to the atmosphere, further polluting the air.

  • Cooking Environment

A chimney keeps the cooking environment clean by expelling out the bad odor, smoke, and grease particles in the kitchen instantly.

Contrary to this, an exhaust fan takes a certain time to expel out the smoke, odor, and hot steam. This is because the placement of an exhaust fan is far away from the stove.

The oily or greasy particles stick to the blades of the fan. Hence, the exhaust fan requires frequent cleaning, at least once a month.

  • Maintenance

The maintenance of the chimney is very important to maintain and ensure its working conditions. An unclean chimney may create more noise and even performs badly.

The exhaust fan requires low maintenance when compared to a chimney.

  • Electricity Consumption

A chimney consumes approximately about 230 watts of electricity.

An exhaust fan consumes less electricity than a chimney, which is approximately about 65 watts.


If you consider the benefits that chimney has over exhaust fans, the chimney is the obvious solution for Indian kitchens. While exhaust fans are less expensive and consume less electricity, they do have certain limitations. Chimney provides you with more comfort while cooking. It reduces the effort of kitchen cleaning and keeps the kitchen free from smoke and grease.
