Filter vs Filterless Chimney | Which is better for Kitchen?



Indian cuisine involves a lot of oil and spices. As a result, there is soot and smoke in the Indian kitchens. Installing a kitchen chimney is ideal for getting rid of the smoke and odor from the kitchen.

If you wish for an ideal kitchen chimney for your home, you have two types of chimneys to choose from, the filter chimney and the filter-less chimney.

Let us compare the two technologies to understand their working to decide which of the two types is better.

Filter Chimneys

You get different types of filter chimneys on the Indian market. They are charcoal filters, mesh filters, also known as cassette filters, and baffle filters. The filter’s primary job in a kitchen chimney is to trap heavy particles like oil and grease while allowing the smoke to escape.

Here is a comparison between the three types of filters in kitchen chimneys.

Cleaning and maintenanceDifficult to clean and requires frequent cleaningModerate and requires cleaning once a quarterNot washable
What happens if not cleaned regularlyReduces suction power and increases noiseNot much effect, but it is better to clean themNot washable
Noise and filter durabilityMore noise than other filters Moderate lifespanModerate noise, Lasts longMore noise, Requires frequent replacement

From the comparison above, one can deduce that the baffle filters are best suited for Indian kitchens. Though comparatively expensive, these filters do not require much cleaning and maintenance.

The best aspect of baffle filters is that they are removable. Therefore, it is easy to clean them with soap and water.

Mesh filters are not fit for Indian cuisine at all. Charcoal filters are not feasible because they require frequent replacement.

How do baffle filters work?

Baffle Filter
Baffle Filters

Baffle filters are made of stainless steel or aluminum curved panels. The design is such that the curves cause the smoke rising from the gas stoves to change direction. As a result, the oil and grease particles stick to the baffle filters.

These filters work on a unique ‘cut and splash‘ mechanism that separates the oil particles and odor from the smoke. The smoke moves through the panels effortlessly without any resistance.

Though the baffle filters trap and stop oil particles, it does not affect the suction power of the chimney. Hence, these baffle filters are ideally suited for the Indian kitchen.

Cleaning the baffle filters is easy. Besides, they require cleaning once a quarter. You can detach the baffle filters from the chimney and clean them separately.

Why are baffle filters preferable to others?

  • They suit the Indian cooking style.
  • Cleaning and maintenance of baffle filters are easy.
  • These filters last long and provide good value for money.

What are the concerns of baffle filters?

  • Compared to the conventional mesh/cassette filters, baffle filters are expensive.
  • Baffle filters weigh more than charcoal filters and mesh filters.

What is a filter-less chimney?

The filter-less chimney is the latest addition to the Indian kitchen appliance scene. The name itself suggests that these kitchen chimneys do not have any filters. Hence, it removes a significant handicap of kitchen chimneys, that of cleaning and maintenance. As filter-less chimneys do not require any manual cleaning, it reduces maintenance costs to almost zero.

Cleaning of filter-less chimneys

Filter-less chimneys come equipped with oil collectors that collect the oil from the smoke emitted from your cooking activities. These chimneys feature an Auto Clean functionality that cleans the chimney automatically.

Advantages of filter-less chimneys

Filter chimneys have a drawback as the filters can get choked with oil and grease particles. It can affect the free flow of air and reduce the chimney’s suction power. The absence of filters in a filter-less chimney removes this handicap.

Besides, the motor in a filter-less chimney is placed strategically to allow the smooth movement of air and smoke without compromising on the suction capacity.

Compared to the filter chimneys, filter-less chimneys do not make much noise. However, these appliances are not the most ideal for households with heavy spice and oil usage.

  1. Thanks Mam, it helps a lot to decide the right chimney. Filter-less may seem attractive due to almost zero maintenance, but I learned here that baffle filter is comparatively the better choice for typical Indian spicy/oily cooking.
