How frequently should you clean the kitchen chimney?

The period of cleaning the kitchen chimney depends upon the type of food prepared in your kitchen. Overall, a kitchen chimney should be cleaned up at least once in 2 months. But if you frequently prepare a lot of oily and spicy food, then you should consider cleaning the meshes and filters of your kitchen chimney once a month. The frequency of cleaning chimney also depends upon the type of filters present in the chimney, such as :

  • Cassette Filters – If your chimney has this type of filter, you would be required to clean the filters once in 8-10 days. It is because these filters are made up of multiple layers of aluminum. They contain small pores and grease sticks, which easily get blocked. 
  • Baffle Filters – These filters come with the technology of separating smoke and grease. That means they don’t get clogged with dust and grease easily. So, with these types of chimney filters, you are required to clean them once in 2-4 weeks. 
  • Charcoal Filters – The charcoal granules present in the filter absorb the smoke, odor, and grease. That’s why these filters cannot be cleaned, so they should be replaced once in 3 – 6 months.

Why is it important to clean the kitchen chimney periodically?

The chimney in your kitchen helps remove all the smoke, airborne grease, vapor fumes, and steam that accumulate in your kitchen environment while preparing Indian food. A chimney has several components such as meshes, filters & baffles, which gets greasy after some time. Once a thick layer of grime gets deposited over the small pores and surface of the chimney’s components, it blocks the flow of gases through them.

Therefore, it becomes necessary to clean them periodically to keep the chimney in a functional state. The microbial infestation is another problem that can be caused if the chimney is not cleaned correctly. In this problem, the deposited grime areas grow bacteria and fungus, which can cause health problems and can also lead to foul odor in the long run.
