Costly to get it clean from professionals

If you hire professionals for cleaning it regularly then it will cost you a lot. Many kitchen service providers selling their packages for cleaning them four times a year. They charge around 1100 INR (approx. ) for their 4 services. Chimney cleaning charges in western countries may be high.

But in three months it becomes too dirty. So why spend money on cleaning it. Instead, learn the ways to clean filters at home without spending money.

When was the last time you cleaned or get cleaned your chimney’s filter?

If you do not regularly clean the chimneys. It collects oil, and it becomes so grease and clogged. Then their suction power will reduce.

Drawbacks of dirty and greasy chimney filters

  1. It does not look good. It completely ruins the look of your kitchen.
  2. Over the period of time filters blocked from grease. And due to that sucking power of chimney will reduce.
  3. Grease/oil may drops from the filters on the stove. Due to that, it can ignite a fire in the house.
  4. Sometimes due to the less effectiveness of chimney, smoke and steam are showing in your kitchen. And the surrounding area near the stove also gets dirty.
  5. If you are using a mesh filter and not cleaning it regularly. Then filters can be blocked with oil and grease. And you need to replace it with new filters.

That’s why it’s important to clean filters regularly.

There are many types of filters present in the market. But mesh filters over baffle filters are more common. For Indian kitchen baffle or mesh filter are more suitable.

I would suggest that use the baffle filter in your chimney.

Charcoal filter chimneys cannot be cleaned. They need to replace every six months. So, it is not suitable for the Indian kitchen.

How often you should clean the filters

We should clean chimney filters every 15 days. Otherwise, once in a month cleaning is required.

In the Indian kitchen scenario, cleaning of chimney filters every 15 days is suggested. In other countries, you can clean it according to your cooking style etc. If you are using fewer oils and do less cooking then once in a month is suggested.

In a simple way, look at the filters and check how dirty are they. If they are dirty and cleaning is required. Then, clean it, otherwise, use it for a few more days.

From the above methods which I mentioned, we can clean chimney filters at home. But the chimney gets oily and greasy from the inside over a period of time. For cleaning chimneys from inside you need the help of professionals.

They will remove the whole chimney from its place. They will disassemble it and remove the motor, electronic buttons, filters etc. Then they will clean it from the inside.

Cleaning from inside is required once a year. So, it is advisable to take the help of professionals. As it is not easy to install and disassemble it for cleaning and reassemble it. This service is also not costly.

  1. IN Method (5) Keeping MESH FILTER WITH PLASTIC PARTS get damaged if we keep them in HOT BOILING WATER WILL DAMAGE THE PLASTIC CLIP OF THE MESH FILTER. WE have to handle the Plastic part side very carefully.

    1. Hi,
      In my chimney’s filters, there are no plastic parts thats why I used this method. If your chimney’s filter has any plastic part then you should choose other methods which I mentioned above.
      and thank you so much for highlighting this point.

  2. Dear Neetu,

    Your tip of cleaning the filter with washing powder was awesome. Tried it and got excellent results. Didnt have a big patila where my filter could fit in, so i just closed my kitchen sink n dropped a vessel of hot water (boiled again after adding washing powder) on the filter and in no time got a clean mesh. Gave a bit of scrub with the toothbrush. Thanks for the tip.
