Types of Kitchen Chimney Filters Every Desi Cook Must Know

Appearance and design aren’t just enough to buy a kitchen chimney. The performance of your chimney merely depends on the type of filter it has.

There are basically three types of kitchen chimney filters, Baffle, Mesh and Charcoal; each with varied properties, performance abilities and cleaning processes. The type of filter you must choose depends on the type of cooking you mostly do.

For instance, a mesh filter can be good for you if your cooking doesn’t involve much oil. A baffle filter can be your option if your cooking takes much time.

A charcoal filter is good for capturing pungent smells preventing occasional coughing and sneezing while your spices splutter.

Confused? Let’s discuss these types of chimney filters in detail and so that you choose the right one for your kitchen. We have also answered some of your queries to help you make a better purchase.

What is a Kitchen Chimney Filter?

Indian cooking mostly involves oil and spices which release heavy smoke, soot and sticky particles that can be difficult to remove. Here’s where a chimney filter comes into action.

It has the potential to suck the smoke, oil particles, and grease from the air which helps you to keep your kitchen odour-free and tidy.

The chimney filters these days are more flexible and can be removed from your chimney and cleaned easily.

Chimney Filter Types:

1. Mesh/Cassette Filter

This type of filter resembles a mesh that traps the oil particles and grease while allowing the smoke to escape through the tiny pores in it.

Materials Used:

Mesh filters are usually made of aluminum or stainless steel.

The stainless-steel filters are expensive than aluminum ones and heavier. However, they are easy to clean.

The aluminum filters are lighter but require much effort to clean. These are also prone to corrosion.

Suitable For:

Mesh filters can only handle little load. So, Indian kitchens with smaller families where the cooking time is less can go for this.

Cleaning Process and Frequency:

Dip the mesh filter into hot soapy water and let it rest for 30 minutes. Then, using baking soda and dish washing liquid, scrub the filter till the pores of the mesh are clearly visible.

Both stainless-steel and aluminum mesh filters must be cleaned once a week.

You can even hire a member from the chimney cleaning agency to do the work.
