Why Should You Clean the Kitchen Chimney?

Now that you know how to clean kitchen chimney let us focus on why you need to do that. To be honest, the function of your kitchen chimney is to ensure that there is no smoke, vapor fume, steam from the kitchen which remains.

Check out the 5 most important benefits of using a kitchen chimney.

The chimney sucks all the smoke, steam and oil particles through the chimney filters. The chimney filters are designed in such a manner as to only allow smoke to pass through them. This smoke is sucked by the exhaust fan of the chimney and released in the open air through the duct pipe.

But what happens to all the oil particles?

The chimney filters trap all the oil particles. These oil particles get deposited inside the filter and on the filter surface and form a greasy layer over time. If filters are not cleaned regularly then this can create thick layers of grease which can clog the filters and reduce the suction capacity of the chimney.

It is important to clean up the chimney filters regularly to maintain the efficiency and suction capacity of the kitchen chimney.

Another reason for cleaning the kitchen chimney is a microbial infestation. The areas with deposited grime can be an ideal source for bacterial growth which might spread diseases.

Hence, cleaning the kitchen chimney is important because of safety, improved power/suction efficiency, longer life of the blower, and effective removal of oil-grease, odor, and smoke.

How Often Should You Clean the Kitchen Chimney?

It totally depends on the load that is handled by the kitchen chimney of yours and all the different types of food that you tend to prepare as well.

However, if you want a clean and smoke-free kitchen, then you should clean your kitchen chimney at least once in a month. In case you are preparing a lot of oily and spicy food, cleaning the chimney twice a month is recommended.

For those who are using a kitchen chimney which has charcoal filters, replacing the filter every 6 months or earlier is essential.


So, there you have it, people. These are some of the best ways with which you will be able to clean your kitchen chimney with little effort. Use any one of the materials for cleaning your chimney filters in the best way.
