All you need to know before buying a Chimney and Kitchen Hood

Indian cooking  involves lot of frying, grilling using lot of oil and masalas.  The sound of spluttering tadka though gives a lovely aroma and taste but it also leaves its impression on your kitchen tiles and ceiling.  Over a period of time grime collects on the cabinets and over-the-counter appliances. More than cooking, it’s cleaning the kitchen that is cumbersome and discourages many from cooking that sumptuous meal.

A chimney or a kitchen hood is a boon to many who love to cook but withdraw themselves with the thought of watery eyes, odor and grimy kitchen. Now you can cook to your hearts delight by embracing this wonderful appliance.

An electric chimney sucks the air inside the kitchen. The air then passes through the filters which absorbs the heat and traps the grease particles thereby removing fumes and odor and ventilates your kitchen keeping it fresh and odor free.

On the basis of installation, chimney are of two types.

Ducting or extracting:

How it functions: The air that is sucked in passes through the filters. Grease and grime adhere to the filters and the air is expelled out through PVC pipes or a duct. It requires plumbing installation. The number of bends and the length of the hose pipe affects the suction power.  Filter used is either a mesh or baffle filter.

Recycling or ductless:

How it functions:  It has fan or blower and motor. The air passes through the grease filter which traps grease particles. The air then passes through the charcoal filters which absorb the heat, smoke and odors. The purified air is circulated back into the kitchen.

Filters: A filter is the heart of the Electric Chimney. It traps the oil particles and purifies the air. On the basis of material and construction filters are of three types.

Mesh Filter: Layers of Aluminum mesh overlapping each other slightly offset. The mesh has very small holes. When the air passes through the filter, oil and grime adhere to the layers. The pores get clogged very soon and affects the performance of the chimney. Requires cleaning every fortnight.

Higher maintenance and frequent cleaning is needed for Indian kitchen because the masalas get coated onto the filter blocking the holes and thus the suction power gets reduced.

Maintenance:  Warm soapy water/detergent. Can be cleaned in dishwasher too. The cleaning is easier than baffle filters.

Baffle Filter: Layers of steel/aluminum are overlapped in a fashion which changes the direction of air flow. It uses the ‘cut and chop’ technology to separate oil and spices from the smoke. The suction power gets hardly affected even if the oil gets collected in the first layer. Perfect for Indian style of cooking.

Maintenance: Needs cleaning once in 5-6 months. Gets rusted with use. Some models have easy removal others require technician. The filters need change in 4-5 yrs.

Charcoal Filters: They are primarily used for odor absorption. It has a block with charcoal granules. The absorption capacity depends upon the thickness of filter and size of charcoal granules. It is used in Ductless chimneys. It does not come in-built in always but available at an extra cost.

Maintenance: Needs periodical replacement 3-6 months depending upon the intensity of cooking. It cannot be washed.  Some high end models have indicators for filter change.

On the basis of functionality and fashion chimneys can be categorized into conventional and contemporary.

Conventional chimneys are straightline chimneys that basically perform the sole function of keeping the kitchen fresh and ventilated are available in both ducting and ductless mode

The contemporary chimneys come in various design and types to suit your budget and lifestyle. They have a hood which again comes in various styles.

Wall Canopy Hood

Wall Canopy Hood

Types of hoods

  • Wall canopy They are the most common hoods. They are fixed onto the wall and the hood hangs above the stove. It comes in various styles and designs.
  • Downdraft chimney   It is a very stylish and sleek chimney which comes over the stove when in use.  It has a push button which pops and retracts the chimney.
  • Island canopy They are fixed on the ceiling and seem like hanging from nowhere. They are for the counter-top cooking ranges and gas stoves. It is an ideal choice for hobs with western styled counters.
  • Built-in or integrated hood They remain concealed behind or under the cabinets and blend with the tapestry of the kitchen.

Pointers to ponder before buying a chimney

  • Suction Power Is the capacity of the motor to suck oil particles and odor. It is measured in cubic meter per hour(m3 per hour). For Indian kitchen a chimney with higher air suction capacity is ideal. For frequent cooking the range should be between 400 m3/hr to 1000m3/hr depending on the size of your kitchen. The chimneys with a long hose have generally more suction power.
  • Filters If the filter does not function properly the suction becomes poor and can pose a health hazard. The choice of the right filter improves the performance of the chimney.
  • Motor/Blower The motor should be sealed so that dust and grime does not get into it. Aluminum non-stick blower and motor saves you from agony of periodic servicing of internal parts.
  • Size The size depends on the size of the kitchen. A 3feet stove should have a 3feet chimney. Standard chimneys come in 2ft and 3ft size.
  • Maintenance and Care It is advisable to go for a chimney which requires less maintenance. Install the chimney at low height (4feet) so that cleaning is easy and it effectively removes the smoke and oil particles out.
  • Budget Electric chimneys come in the price range of Rs 3000 to Rs 100000.
  • Noise The noise that is heard is that of the air circulation. You may like to consider this before buying your chimney. Some chimneys have a silent-kit installed which makes it silent or less noise.
  • Speed Entry level chimneys have single speed option but advanced ones have variable speeds to ventilate the kitchen faster.
  • Aesthetics Chimneys are available to suit every section and taste of the society ranging from modest rates to expensive ones. Depending on your budget, lifestyle and kitchen décor you may choose the best. Some brands have the option of customizing the looks to match your kitchen décor.
  • Warranty and Service Most chimneys come with warranty of 12 months but some chimneys come with lifetime warranty. Check for after sales services in your locality because some baffle filters need technician for cleaning them.

Advanced features

Auto Clean chimneys:  Once you switch the chimney ON, the coil that cover the motor gets heated up for 15 to 20 mins. The oil gets liquidized and is let out .The chimney stops after auto cleaning itself..

Split chimney: The motor is installed outside the kitchen hence reducing the sound.

Convertible kits: Some brands have kits wherein a ducting chimney can be converted into a ductless chimney.

Soundproof kits: They ensure that there is absolutely no noise of the chimney.

Detachable oil collector: The oil particles get collected in this and its easy to detach and clean thereby improving the efficiency of the filter.

Auto heat sensor: It detects heats and oil particles and automatically switches on and off.

Indicator/buzzer:  They have indicator lamps or alarms for filter cleaning or replacement.

  • senthil kumar

    Hi sir.
    This site very useful to understand about kitchen appliances. one question please clarify there is any formula to calculate suction capacity of the chimneys & kitchen hood. if available means explain me to my understanding.

    • Hi Senthil,

      To calculate the suction power of a chimney, calculate the area of your kitchen so say for example a 10*12 kitchen with a ceiling height of 10 feet – 10*12*10 = 1200 cubic feet which is roughly 34 cubic meter. So this much space which needs to be cleaned. This much air needs to be cleaned say every 15 times per hour.
      so 34*15 air exchange = 510 should be your chimney’s minimum suction power.

      However keep in mind that if you do lots of frying or regular non-vegetarian food then you need chimneys with better suction powers.

    Can you recommend any specific brands / models of ductless chimneys that are currently available in the market?

  • Sachin Kathare

    can i place a chimney near the window. some say its not ideal to place a chimney near the window as it sucks the dust from outside . your suggestions plz..

    • Hi Sachin,

      Thanks for getting in touch with us.
      The function of a chimney is to throw out impurities like smoke, food particles, carbon, oil out etc and not suck it in. So you can place a chimney near the window. However if you are putting the chimney near a window we are assuming that your hob is near the window too. In that case please take care of safety as the flame can be blown out if the window is open during cooking. So buy a hob which cuts off the gas supply when there is no flame or change the placement of the hob to another location.

      Hope this helps.

  • ajay

    what should be the distance between the celing and the exhaust of the ductless chimney, given the purified air is circulated back. And if the gap is less it will throw up on the gastop causing gas loss.

    • Hi Ajay,

      The minimum safety distance between the bottom of the hood and the top of the cooking hob must be between 60 cm – 80cms. For optimum suction. Smaller or Higher distances must be previously authorised by the manufacturer as it may affect the suction power of the chimney.
      Hope this helps.

  • Debashish Sarkar

    Hi !! Please help me out. I have installed Megaleo chimney but I am not happy with the suction power. Smoke is not sucked though the fan is running in high speed mode. The paper is not sucked when checked below 1 ft distance. Is there any proper method to check the suction power? What is auto mode functioning? please explain.
    .

    • Hi Debashish,

      The suction power of the chimney cannot be calculated by the paper test you did.
      To calculate the suction power of a chimney, calculate the area of your kitchen so say for example a 10*12 kitchen with a ceiling height of 10 feet – 10*12*10 = 1200 cubic feet which is roughly 34 cubic meter. So this much space which needs to be cleaned. This much air needs to be cleaned say every 15 times per hour.
      so 34*15 air exchange = 510 should be your chimney’s minimum suction power.

      However keep in mind that if you do lots of frying or regular non-vegetarian food then you need chimneys with better suction powers.

      Auto mode relates to the auto clean feature in chimney.

      Hope this helps.

  • Rahul Verma

    i have purchased hindware 60 autoclean , currently i used sunflame autoclean which have a water lid to use auto clean , but in hindware water lid is absent , can u tell me how it can works, autoclean without water

    • Hi Rahul,
      Thanks for writing to us.

      More recent autoclean chimneys do no use water to clean. Here the centrifugal force draws the fumes towards the blower so the oil particles gets liquidized and gets collected in a washable oil collector that can be removed and washed once in a month or so depending on the usage.This feature prevents the accumulation of oil, smoke, or grease particles that affects the suction power of kitchen chimney which in turn decreases kitchen chimney performance.

  • Vishant Joshi

    Hi, i am setting up my modular kitchen.
    Please help me to decide
    – shall I go for ducted or ductless chimney?
    – in ductless chimney as air will be recirculated to kitchen, will that affect freshness in kitchen, humidity, etc ?
    – will there be any odours of frying /tadka’s in kitchen and entire home by ductless chimney

    Appreciate your suggestion for making right decision

    Thanks
    Vishant

    • Hi Vishant,

      If space is not a factor then you can go for ductless chimney. Generally ductless chimneys are more affordable than ducted range hoods, and easier to install without the need to externally duct or make changes to the kitchen’s ventilation systems.
      But the charcoal filters used in these type of chimney needs to be cleaned or replaced regularly; ductless hoods generally capture and filter certain types of particles only, so excess heat and moisture is released right back into the kitchen unlike ducted ones.
      In case of oil particles which aren’t always visible, without a range hood/ ducted, these oil particles will have free rein to spread and stick to everything in the near vicinity. This may leave you with sticky cabinets and other surfaces in the kitchen if the space is very less.

      Hope this helps.

  • Tushar Anthony

    Hi! I purchased a Hindware Nevio 60 Thermal Autoclean chimney about a month back.It’s been a month so to try cleaning, I touched the auto clean button, timer of 10 minutes had started but nothing else is noticed like blower on and chimney remained cool and filters didn’t heat up! Is the chimney faulty? How do I check whether the thermal auto cleaning system is working or not? Can someone help?

    • Hi Tushar,

      The chimney must show some sign that auto cleaning is on.
      Since the chimney must be under warranty we would suggest you to call customer care to show your chimney. Even if it is not faulty this might help in rectifying any problems you have in future.
      Hope this helps.
