Baffle Filter vs Filterless Chimneys

Detailed guide on baffle filter vs filterless chimney

In order to understand the difference between baffle filter vs filterless chimney, let’s start by understanding the working mechanism of both these types of chimneys.

Let’s first talk about the baffle filter type of chimneys.

Baffle Filter

Basically, a Baffle Filter is an advanced type of mesh filter that is built with curved plates made up of aluminum or stainless steel. These curved plates on the chimney basically control the airflow and change the direction of the smoke produced in the kitchen that helps in filtering out solid dirt from the smoke fumes produced during cooking.

How does a Baffle Filter Chimney work?

Baffle Filters work on a very simple principle called the “Cut & Splash” mechanism. When the chimney starts sucking in the heavy oily & smoky air, the curved design of the filter changes the airflow to suck it inside the chimney.

As the oily solid particles do not change the direction they get stuck on the filter surface itself. Only the smoke gets entered in the chimney which is then either purified or vented out of the kitchen from the duct. That’s all how a baffle filter chimney work. It just traps the heavy particles on the filter and lets the hot fumes pass away through it.

Baffle Filter vs Other Filters

The main reason why baffle filter chimneys are getting more popular these days is that because of their curved design plates, they are more efficient in nature compared to other types of filter chimneys.

Now because it does not get clogged like other chimneys, it does not need monthly maintenance. However, you would have to get it cleaned at least once in four months.

Modular Baffle Filter kitchen chimneys come along with auto-clean technology. Trust me, the auto-clean feature of these chimneys is a lot very helpful.

You are able to clean your chimney just with a single tap of a button.

But still to maintain their efficiency, baffle filter chimneys with auto-clean technology should be get cleaned at least twice a year. You can either get it done by maintenance team or you can even clean chimney by yourself at home.


Filterless Chimney

As you already know, it does not have any filters. No filters mean it does not require any maintenance, however, you can still take care of it to sustain the long-running life of the appliance.

How does a Filterless Chimney work?

Basically, Filterless chimneys have a dedicated detachable oil collector which collects these heavy solid and dirt particles automatically so you don’t have to worry about the cleaning process yourself.

It sucks in the smoky air along with the heavy solid particles but the auto-cleaning technology of filterless chimneys automatically collects all the oil emitted during cooking. You can easily detach the oil collector to remove the oil from it.

Advantages of Filterless Chimney

The main advantage of a filterless chimney is that it removes the headache of 6 months’ regular maintenance cost. As they do not have any filter, they can not get clogged with heavy oily particles. 

But in baffle filter chimneys, oil and dirt clogging could block the airflow path which would affect the suction power of the motor as well.

Also, Filterless chimneys do not make much noise as compared to the filtered chimneys. In case you think, not having a filter might affect the motor, let me clarify that in filterless chimneys, motors are placed in such a way that there is a complete airflow & solid particles can not block or affect the suction power of the motor.

Disadvantages of Filterless Chimney

The only considerable drawback of a filterless chimney is that it is not suitable for heavy oil usage. We highly recommend you to get a baffle filter chimney if you have frequent heavy oil usage in your kitchen on a regular basis.

But for normal day-to-day usage, Filterless chimneys are considered to be the best option. If you have a small kitchen or you don’t do regular frying or grilling, filterless chimneys are very suitable for you.

Another disadvantage is that Filterless chimneys cost higher than baffle filter chimneys. But you also must consider that they do not require any maintenance so it would be a cheaper option for you in the long run.
