Multiple layers of mesh retain grease, oil particle from smoke and throw out remaining smoke. Mesh holes blocked by grease, oil particles it results reduction of suction capacity. Stainless steel or aluminium is used for cassette filter. Stainless steel cassette filters little bit expensive relative to the aluminium filter.

The charcoal filter is optional filters that are used along with cassette or baffle filter. As the name suggest this type filters made up of charcoal. Charcoal filter absorbs the grease, oil particles in it. Absorption power depends on the thickness of filters and the charcoal granules. The charcoal filter is not washable, depending on the usage you have to change.
