Cleaning of Different Types of Chimney filter

Most of the kitchen chimneys have one of the two types of filter attached to it – a baffle filter or a mesh filter. A mesh filter is made of a multiple layers of stainless steel or aluminum mesh. These filters trap the dirt and grease in the smoke. Over time, the entire filter can get clogged due to grease and dirt build-up. This is why mesh filters need regular cleaning. These filters also tend to be a little more difficult to clean due to the many tiny nooks and corners that need to be reached.

A baffle filter has panels with multiple curves fitted in it. These curves make the smoke curve around to move out, but the grease and dust will not be able to do the same. All of it gets deposited on these panels. This filter does not need cleaning as often as a mesh filter would, but requires cleaning nonetheless.

Most chimneys are fitted with mesh filters. These might be cheaper, but the filter can easily get clogged. Even so, the chimneys fitted with mesh or baffle filters are the ones best suited for an Indian kitchen. A charcoal filter fitted chimney works very well, but the filter needs to be replaced every six months, which can be a cumbersome task, not to mention the cost of these filters would also be an added expense.
