Types of Chimney Filters – A Comprehensive Guide

A kitchen chimney is essential for keeping a kitchen clean, sneeze-free, pollution-free, and hygienic, as well as ensuring that there is no bad odor. The chimney’s primary function is to remove smoke, oil particles, and grease from the air. The overall cleaning efficiency of a chimney is dependent on the type of filter installed inside the chimney.

That’s why we recommend buying an auto-clean filterless chimney if you don’t want this headache. According to The Chimney Guide, these are the best auto-clean chimneys in India.

To make things easier for you to understand, here in this article we have discussed the functioning of three major types of chimney filters available in the Indian market. Each filter has its own set of capabilities and cleaning procedures.

We’ll go through each one of them and make you understand which one is the best to choose from considering Indian kitchen usage. Basically, these are the three types of chimney filters in India. If you want a complete buying guide on which model to buy, here’s a complete kitchen chimney buying guide.

  • Cassette or Mesh Filter
  • Carbon or Charcoal Filter
  • Baffle Filter

Cassette/Mesh Filter

In a cassette filter, multiple layers of aluminum or stainless steel (stainless steel filters are more expensive) are commonly used to capture various particles such as smoke, grease, oil droplets, and so on. The wires are tightly coiled against one another to keep the filter structure in place against the suction pressure of the fan inside the chimney column. To improve the efficiency of the chimney, many layers of the cassette filter are stacked one on top of the other. If you have a convection microwave oven at home, getting this type of chimney as well would add up more points to your overall kitchen.


  • Advanced cleaning capabilities are included with the Mesh filters.
  • It’s the right size, lightweight, and easy to handle. You can take the filter out of the chimney at any time.
  • They are simple to clean and ensure optimum hygiene, enhancing the kitchen chimney’s overall usage.
  • The most significant advantage of cassette filters is that they are less expensive than other sorts.


  • It makes a lot of noise.
  • It is unable to endure high temperatures.
  • Frequently clogs and requires cleaning


This is used as a secondary filter with cassette and baffle filters. It helps both filters absorb oil particles, smoke particles, and grease by sucking up the unwanted scent. They are formed of charcoal, as the name implies. The size and thickness of the charcoal granules determine the filter’s absorption power. It’s typically seen in ductless chimneys and is never available as a built-in filter. This filter will cost you extra money if you want it in your kitchen chimney.


  • Because this type of filter allows nearly every particle to attach to the surface, the chimney can discharge 99 percent pure air.
  • The chimney’s efficiency improves significantly thanks to the charcoal filter layer’s high adsorbing power.
  • It works as a second layer of filtration, preventing greasy chimney walls.
  • Their cutting-edge technology substantially improves kitchen hygiene.


  • The charcoal filter cannot be washed. As a result, the only option you’ll have when it quits operating is to replace it.
  • Because charcoal is used as a secondary layer of protection, chimneys are highly costly.

Baffle Filter

Aluminum/steel layers are used to make baffle filters. The panel is constructed up of several curves through which air passes, retaining oil and grease particles in the process. Stainless steel is used in the majority of baffle filters. During this process, it employs “Cut and chop” technology to retain the oil, smoke, and grease. These filters are ideal for Indian cooking since the oil and grease they gather do not obstruct the air passage.


  • These filters require little upkeep and are simple to clean.
  • A filter’s longevity far exceeds your expectations.
  • It aids in the improvement of airflow in the kitchen, resulting in a more pleasant atmosphere.
  • To increase airflow, the Baffle filter has an effective suction power motor.
  • If you enjoy making spicy foods, go ahead and try them.


  • Because the baffle filters are heavier, they are more difficult to remove from the chimney while cleaning.
  • These filters are also pricey.


By just having a better understanding of the types of chimney filters, you can easily select the most efficient one from the crowd. The two most common types of chimney filters on the Indian market are cassette and baffle filters.

Cassette filters are inexpensive—you don’t have to spend a lot of money to keep your kitchen clean with these filters. However, this filter is inappropriate for the Indian market because we Indians cook our spicy food with a lot of masalas, ghee, and oil.

These filters will not be able to distinguish between oil and spices that are created while cooking. Baffle filters are the most suitable for the Indian market because they can readily separate oil, ghee, and spices, making them ideal for the Indian market. They are ideal for Indian kitchens because of their efficiency, low noise level, and ease of cleaning, as we cook a lot of spicy and oily cuisine.
