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. But Aluminium cassette filter is lighter, easy to handle, but carefully cleaning is required whereas stainless steel is heavier, a little bit tricky to handle but cleaning is very easy. Clean chimney can be done with dishwashing liquid, baking soda. Need to wash once a week. As per our Indian cooking habit mesh / cassette filter is not suitable for us.
The baffle is flow control panel. The panel made of multiple curves through which air moves, during this process panel retains oil, grease particles in it. Mostly baffle filters made up of stainless steel. Aluminium baffle filters are also available in market but rarely. As grease, oil particles are not an obstacle to the flow of air, so it affect on the suction power. Need to clean once a 3 to 4 weeks. Best suitable filter for Indian cooking habits.
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.
The chimney filters should be cleaned for every 3-4 weeks because the greasy filters will reduce the chimney efficiency. So it is better to clean the chimney filters at least once in a month. Cleaning baffle filter is little easy than mesh filter as well as mesh filter needs frequent cleaning, whereas baffle filters not. You can clean the chimney filters using simple ingredients like hot water, baking soda, lemon, vinegar, caustic soda or paint thinner.
