Types of Kitchen Chimney Filters

Types of chimney filters are divided into 3 categories according to the material, structure, and filter method.

  • Cassette / Mesh filter
  • Baffle filter
  • Carbon filter

Cassette / Mesh filter

Typically, filters have multiple layers of aluminum or stainless-steel mesh filters to trap solid particles while not allowing smoke to escape. However, these filters require a lot of maintenance.

They can also reduce the suction capacity of filters due to being full. It is best to wash filters regularly, either by yourself or by someone else.

Baffle Filter

Most Indian chimneys have baffle filters. In fact, it is an improvement in aluminum wire mesh filters. Research has shown that these filters are 30% better than line filters. The construction of the panel on the filter should have several curves so that the smoke does not escape freely while preventing the grease from entering.

The baffle filter is relatively easy to maintain, as it has to be cleaned once every 3 to 4 months. Nowadays you have a removable amplification filter that allows you to do this at home and clean it thoroughly. You do not need a technician to do this.

Carbon Filter

Just as your water purifier has carbon filters, you can have these filters in your filters. They remove food odors. This charcoal filter is made of charcoal and can be used both in duct and ductless chimneys.

Oil and other greasy particles can stick to carbon filters, so they need to be replaced after about six months. These kinds of filters are really quite well-liked in India.

Different Kinds of Kitchen Chimneys

The type of kitchen chimney you want to buy depends on the structure of your kitchen and the cooking platform, hob, and oven where you plan to install it. The kitchen chimney can be divided into 4 types depending on your skills.

  • Wall-mounted chimney
  • Island chimney
  • Built-in chimney
  • Corner chimney (very rare in India)

Wall Mounted Chimney

The kitchen chimney is on the wall and hob to the wall.

Wall chimneys are chimneys that are attached to the wall above the hob. Designed for traditional kitchens where the oven is close to the wall, it conforms to the Indian style of cooking.

Island Chimney

The cooking platform is in the middle of the kitchen, away from the wall. In this case, the kitchen chimney hangs on the ceiling above the hob.

By having an island kitchen, you can save on counter space by eliminating the need for a built-in oven and stove. The island also frees up space in the kitchen for extra cabinets and appliances.

An island kitchen chimney is a great way to increase the suction power of your stove. A properly installed island kitchen chimney will connect to your existing heating system and allow you to use all of the heat from your stovetop. This will save you money on your energy bill, as well as help to improve the efficiency of your cooking.

Built-in chimneys

Built-in chimneys are in the kitchen wooden furniture and work on the wall.

A built-in kitchen chimney is a great way to increase the efficiency of your stove or oven. A chimney with a built-in stove or oven will draw in more air than a traditional kitchen chimney, which can result in a greater burn rate and increased cooking performance.

Corner chimneys

The corner chimney is in the corner of the kitchen where there is a hob on the wall. A corner kitchen chimney can be a great solution for a small kitchen with limited space. By locating the chimney in a corner, the stove and oven can be placed closer to the wall, saving valuable counter space.

A Few More Important Factors to be Considered

suction power of kitchen chimney

Suction Power of the Chimney

Suction power is the engine’s ability to absorb oil particles and odors. It is measured in cubic meters per hour (m3 per hour). A kitchen chimney with high air capacity is perfect for Indian kitchens. For frequent cooking, depending on the size of your kitchen, the range should be between 400 m3 / h and 1000 m3 / h. Long hose chimneys usually have higher suction power.


If the filter does not work properly, the suction will be poor and it can be a health hazard. Choosing the right filter will improve the performance of the fire extinguisher.

Motor / Blower

The motor should be sealed to prevent dust and dirt from entering it. The non-stick fan and aluminum motor save you the hassle of regular maintenance of the interior.


The size of the chimney really depends on the size of your kitchen itself. A 3 – foot stove should have a 3 – foot chimney. Standard chimneys are available in 2 foot and 3 – foot sizes.


It is advisable to choose a chimney that requires less maintenance. Place the chimney at a low height (4 feet) to easily remove and effectively remove fumes and oil particles.


The prices of electric kitchen chimneys range from around Rs. 3000 to Rs. 1,00,000 so there is a chimney for almost everyone in the market, those with high budgets as well as those with very low budgets.


Whatever noise that you do hear from the chimney is most usually the noise of the air circulation of the chimney. There are however some chimneys in the market that come installed with a gadget or a kit called the ‘silent kit’. This silent kit makes the chimneys more or less silent or the chimneys produce sounds that are really close to being silent.


The speed of a chimney is the measure of how quickly the chimney ventilates the kitchen. Higher speeds mean faster ventilation of the kitchen. Entry-level or basic low-level chimneys only have a single speed option, whereas the latest chimneys have multiple speed options to ventilate the kitchen faster, or as fast as you want it to be ventilated.

Aesthetics of the Chimney

Chimneys are available in every part of society, and in every price – range starting from really economical and going all the way to really expensive. Depending on your budget, cooking style, and kitchen decor, you can make the best choice.

Your kitchen chimney has to look the best and not just look the best itself but the chimney also needs to make your kitchen look good by setting in with your kitchen décor. Fortunately, there is a wide range of looks and aesthetics of kitchen chimneys to choose from and you can make your kitchen look way better than before by adding the chimney.

Even if your kitchen has a unique design, or you cannot quite find the right chimney to match the style or taste of your kitchen, some brands also offer a custom look to match your kitchen decor. Hence, this way, a kitchen chimney not just keeps your kitchen atmosphere well ventilated and clean, but also adds to the beauty of your kitchen.

Warranty and Services for the Kitchen Chimneys

Warranty for the Chimney is a must as any kind of malfunction in the chimney might cause the chimney to break and cause an inconvenience for you. A chimney in warranty, however, can be replaced or repaired in such a case without any cost.

So, be careful that you buy a chimney that comes with a warranty. Fortunately, almost all chimneys come with a warranty. Most chimneys come with a 1 – year warranty, while some chimneys even come with a lifetime warranty. Kindly do go and check for the after-sales services for the best user experience that you can get for the chimney that you are trying to buy.

How to Calculate Kitchen Chimney Suction Power and Capacity

kitchen chimney suction power calculator

The suction power of your chimney generally depends upon the size of your kitchen. The basic method of how to calculate kitchen chimney suction power is to simply calculate the volume of your kitchen and multiply that by ten. Simple right? You must already be feeling like a chimney suction power calculator. 

The result will be your required chimney suction power. Here are some tips to help you get the chimney required suction power and calculation method. We hope this helps you choose the right kitchen space.

Factors that Affect the Suction Power of a Chimney

  • Ducting size 
  • Ducting length
  • Ducting diameter
  • Number of bends in ducting
  • Cooking habits

Duct size varies from house to house depending on the kitchen infrastructure. Longer pipelines require more effort to remove smoke and air, so more suction power is required. Small diameter pipes become a barrier to smoking. It is advisable to always use small pipes of large diameter.

The number of turns in the drainpipe allows more time for the cigarette air to escape. So always avoid the number of bends in the duct installation. Chimney suction power is higher for the vegetarian kitchen than for the vegetarian kitchen. Eating vegetarian food smells more smoke than vegetarian food. To emit more smoke, the smell needs more suction.

Calculating the Right Amount of Suction Power for a Kitchen Chimney

The more spacious the kitchen, the more suction you will need for the chimney. The rule of thumb is this: The kitchen chimney has to fill the kitchen ten times an hour.

To determine the required suction power of the chimney, we need to calculate the volume of the kitchen and multiply the volume of the kitchen by ten, because the chimney in your kitchen will refresh your kitchen ten times in an hour for which it has to be filled with air.

To calculate the size of the kitchen, you need to know the length, width, and height of your kitchen, which increase together. Finally, multiply the resulting volume by ten and you will get the desired chimney suction power in your kitchen.

Let us consider that the size of your kitchen for the moment is: The size of your kitchen is 4 mx 4 mx 2.5 m = 40 m³. Fresh air, equal to the volume of the kitchen, needs to be exchanged 10 times per hour, so 10 x 40 m³ = 400 m³ / h. So, your kitchen needs a chimney having at least 400 m³ / h suction power.

A Few Tips and Tricks to Improve the Suction Power of Your Chimneys

  • The higher the suction power of the chimney, the better the chimney is. The highest suction power chimneys are usually the best ones in the market.
  • Effective suction power usually comes in a kitchen chimney with a larger hose (wider filter area).
  • To improve the suction power of the chimney, it is advisable to use a baffle filter instead of a cassette filter as the effect of oil and grease on the baffle filter does not really affect the suction power of the chimney all that much.
  • Regular cleaning is recommended for the suction power needed to quickly collect fumes, odors, and oils.
  • Surya TD 1400M3 Chimney with 1400 m³ / hr is one of the best and highest suction power chimneys out in the market.

Disadvantages and Downsides of High Suction Power Kitchen Chimneys

First and foremost, you need to know that high suction power kitchen chimneys make lots and lots of noise. More suction power means more noise. The solution to this problem or an alternative to the high suction power kitchen chimney is to go for the split kitchen chimney in which suction motor is mounted outside of the home which obviously makes a drastic reduction in noise as all of the noise will be outside your house and not inside.

More suction power means more power consumption. All that extra suction does not come for free. Obviously, by having more suction power, the machine is doing quite a lot of extra work which needs quite a lot of extra energy or power. Therefore, power consumption also increases with an increase in the suction power of the kitchen chimney.
