Baffle Filter VS Cassette Filter: What is Difference & Which One is Better?

Your kitchen’s exhaust and ventilation system demands the best of the best components. Compromising the quality in those aspects can potentially lead to severe health consequences. One such field that requires 100% attention is the filtering system used in the chimney.

Generally, people are often confused between baffle and cassette filters as both efficiently eliminate grease from the air through the air filtration system.

As per the National Fire Protection Association, commercial kitchens must use baffle filters on top of cassette filters. But the same does not apply to home kitchens, which is why it is necessary to make the right choice.

In this article, we will discuss all the advantages and disadvantages of the baffle and cassette filter that provides a clean cooking experience.

Baffle Filter VS Cassette Filter

Cassette Filter

In this type of filter, numerous mesh layers retain the oil and grease particles and eliminate the smoke from the kitchen. The cassette filter is composed of aluminum or stainless steel. The cassette stainless steel filters are a bit more expensive than the aluminum ones. But cassette filters made of aluminum are easy to handle, lighter, and require careful maintenance. On the other hand, stainless steel models are hard to handle, bulkier, and easy to clean.

Advantages of Cassette Filter

  • It is cheaper than the baffle filters.
  • Lightweight to use and easy to detach the filter from the chimney
  • You can wash the parts in a dishwasher.

Disadvantages of Cassette Filter

  • You have to clean them regularly, at least once a week.
  • The oil or grease attached to the filter might catch fire when not clean for long enough.
  • It prevents the flow of the air.
  • The chimney with a cassette filter creates a bit of noise during operation.
  • They are not so durable in high temperatures.


Baffle Filter

The baffle is known as the panel for controlling the flow. It consists of multiple curves through which there is a movement of air during which the filter stops the grease and oil particles in it. Most of the baffle filters are composed of aluminum or stainless steel. You can clean a chimney with a baffle filter once in 2 to 4 weeks.

Advantages Baffle Filter

  • The filters are hassle-free to clean and low maintenance than the cassette filters.
  • The parts of the filters are dishwasher safe.
  • The motor power comes with effective suction to increase the flow of the air.
  • Ideal for superior filtration of grease and oil
  • Comes with corrosion and flame resistance
  • Exceptionally durable to use
  • Cost-efficient for long-term usage

Disadvantages Baffle Filter

  • A little bit heavy, thus removing them from the chimney is difficult.
  • More expensive than the chimney with cassette filters


Difference Between Baffle and Cassette Filters

Now let us check out the main differences between cassettes and baffle filters as below.

Cassette Filter Baffle Filter
Composition Composed of multiple aluminum layers Composed of multiple curve panel of stainless steel
Working Principle Aluminum can catch oil and grease particles from the smoke Curves in the panel of stainless steel catch grease and dirt particles
Cleaning process Difficult Moderate
Cleaning Frequency Once every week Once in 2 to 4 weeks
Consequences of not cleaning Grease and oil in the mesh the chimney suction power and enhance the noise The grease and oil stuck in the filter do not have an impact on the noise of suction power
Noise High Moderate
Filter durability Moderate High
Prices Cheap expensive



In the past decades, people primarily install cassette filters in commercial kitchens. However, it is always better to use baffle stainless steel filters to prevent flames and fire in the kitchen by offering a higher protection barrier. Thus we can conclude by saying if you are looking for something which will last long, it is lighter and requires less maintenance, and then it is better to choose a chimney with baffle filters. But if you want something on a budget, then cassette filter chimneys are also great options to go. So choose well which filter will be suitable for your kitchen!
