CASSETTE FILTER VS BAFFLE FILTER Comparisons & Differences – Which Chimney is Better

We have already discussed the advantages and disadvantages of both of the filters. In this section, we will study the detailed features of both of them.

The holes in the cassette filter segregate the oil and grime from the sucked air and the somewhat cleaner air is upheld through the PVC pipes to be deported from the home. 

On the other hand, the superior airflow of the baffle filter has a productive suction power of the motor. Due to centrifugal forces, oil particles are compelled to move toward the blower wall and compiled simply to eliminate and washable collectors or bowls. 

This detachable oil collector needs to be rinsed once a month, confiding on use. That is why the baffle filter lasts long.


Construction Material:

Cassette filters are composed of aluminum and stainless steel. The aluminum cassette filters are low in price. So, it is lightweight. On the other hand, baffle filters are composed of multiple curves in the panel of stainless steel. The stainless steel in the baffle filter helps in catching grease and dirt particles. 


Working of the filters

Cassette filters are mainly composed of stainless steel and aluminum. The aluminum has ample chances of getting fire from the grease and oil. There are fewer chances of catching fire in the stainless steel. 

However, one needs to be careful in this matter. On the other hand, baffle filters possess curves in the panel of stainless steel to catch the oil and grease effortlessly. To avoid these risky circumstances, it is better to clean the cassette filter regularly at least once a week. 

In the case of baffle filters, no such risks are associated. One can clean the filters once in two to three weeks.



Cassette filters can be made up of two metals: aluminum and stainless steel. The one which is made up of aluminum is easy to handle because of its lightweight. However, it needs proper maintenance so that it doesn’t catch fire.

It is effortless to clean. But the baffle filter is heavyweight, so cleaning it is difficult.

The cassette filter produces lots of noise during the operation. Sometimes the noise becomes unbearable. People may have to shift from the kitchen to avoid the noise. On the other hand, the baffle filter does not produce sound at all. 

Sometimes, a moderate noise comes. It gives a smooth operation without any annoying noise. One would not feel any disturbance while the operation goes on.
