A kitchen chimney mainly functions to keep the air cleaner at your kitchen. In case if you cannot have a proper ventilation arrangement for your closed kitchen, this appliance helps you to be the best alternative. However the kitchens with the modern planning of the house which are placed open to spread the air, still face the real challenge to reduce spreading the smoke from kitchen to the surrounding rooms for the rest of the home. So it can be installed exactly above the gas stove or hob to grab the smoke and odour produced from the food while cooking. This process of reducing the smell happens with the help of filters placed in the chimney which inhale the smoke and odour.
Chimney comes with varied suction capacity which stands to be the foremost important feature for it to be purchased. For a typical Indian kitchen, having a chimney hood with a higher Suction Capacity ofAbove 1000 m3/hris recommended. However choosing a chimney also depends on the size of the kitchen,400 m3/hr- 1000 m3/hr could be the range based on the size and usage of your kitchen.
In these kinds of chimneys the duct helps spreading fresh air round the kitchen after the air containing smoke and odour is sucked in. The suction power of the chimney depends on the length of the pipe in these cases. Efficiency which is the major thing can be improved when the bends formed in the duct are reduced. Ducted chimneys mainly use baffle filters.
Baffle filters work by changing the flow of air, such that dirt and grease gets captured in the stainless steel/aluminium panels. They are widely popular in India. Find more baffle filteroptions here.
For the ductless chimneys, Filters made of charcoal spread fresh air in your kitchen after absorbing all the grease, oil and dirt. Here lies a dis advantage for these kind of chimneys. Unlike the ducted chimneys which have a greater suction capacity and efficiency, these have very less suction capacity comparatively. So this in turn reduces the flow of fresh air in your kitchen with these type of chimneys.
Charcoal/ Carbon filter
Charcoal filters use charcoal to absorb the oil and grease in the air. It cannot be washed, but needs to be replaced for every few months. The size of the charcoal particles affects the absorption capacity of the chimney. These filters are very expensive. Find morecharcoal filteroptions here.

Mounting is another feature which needs to be looked at. When considering the style which brings a great look for the kitchen with your chimney, mounting also plays a vital role.
Chimneys can be installed or mounted in various ways :
1. Wall mounted
As the name suggests, these are mounted on a wall and are known to be the most convenient and popular chimneys. They support both ducted and ductless chimneys. They can come in a wide variety of designs and finishes, and offer different suction power options. LED lights which are an added feature can also be fixed on them. Wall mounted chimneyssave space as the duct is against the wall.
These are also called asBuilt in chimneysand they are placed into the cabinets. They do not expose out like other chimneys. They are most suitable for ductless chimneys where the air is recycled back into the kitchen. There is no plumbing involved - there are no pipes that need to be fixed. They also usually come with sensors which mean that they need not be operated manually.
They are the ones requiring huge suction capacity to suck air from the hob as they are placed at a larger height. AndCeiling mounted chimneysare also not so preferred as they require heavy installation of pipes for the air to be blown out.
They are available for both ducted and ductless chimneys. They are specifically for island layout kitchens.Islander hoods particularly for a large sized kitchen is preferable.

5. Downdraft hoods
They are fitted into the kitchen worktop and are raised by pressing a button. They are applicable for both ducted and ductless chimneys. A down drafted chimney hood includes an advantage of installation at a lower height that could be operated easily. These do not interfere with the look of your kitchen at all, since they simply are part of your worktop and can be raised only when needed. You can explore different models of Downdrafts.
Consideration of factors while choosing a kitchen chimney
Suction power: Based on the amount of cooking involved and how much oil is being used on a regular basis, suction capacity depends on choosing certain kind of chimney hood that suits the environment.
Material: Chimneys usually come with stainless steel (SS) or glass finishes. Noise level: When there are kids or people working at home, then this is the main thing to be noted. For such cases the noise delivered by the chimney might be a heavy disturbance for few chimneys available in the market. Extractors which absorb the heat or smoke are quite noisy some times, So it’s better to have an external motor which keeps the sound away while cooking.
Light:A hood with a light helps cooking easier when the room appears to be darker.
Bends in the duct: Make sure that the bends in the duct don’t halt or stop the passage of air. The air flowing through the pipes have a free flow only with smooth curves, while the right angled bends or too much curved bends in the duct prevent smooth flow of air flowing outside through the duct.
So while choosing a chimney, make sure to keep filter and suction capacity into consideration. Check with the best setup that suits your kitchen. Based on the use of the kitchen, if you have heavy duty appliances for cooking it’s always better to have ducted chimneys which can be wall mounted or islander. Else you can go for the ductless chimneys with less cooking activities happening at kitchen.
