Don't buy an air purifier for the kitchen
The verdict
Cooking is usually the single largest pollution exposure in an Indian home, and a purifier is the wrong instrument for it. It is fighting a source emitting continuously a metre away, grease aerosol coats and ruins HEPA media quickly, and capture at the source is more effective by a wide margin. Before spending anything, check whether your kitchen chimney ducts outdoors or recirculates — a large share of Indian flat installations recirculate, which returns combustion gases to the room.
When this does not apply to you
Placed here rather than at the end, because if one of these describes your situation then the rest of this page is the wrong advice and you should know that now.
Your kitchen is open-plan into the living area
Then a purifier in the living space, positioned away from the hob, is a sensible support measure once the extraction is right. It is still second in the order, not first.
You cannot install a ducted chimney
In some rented flats and older buildings, ducting outdoors is genuinely not possible. In that case a purifier in the adjacent room with the kitchen door closed is the best available compromise — but recognise it as a compromise, and open a window while cooking.
You have a gas appliance and no CO alarm
Neither a chimney nor a purifier substitutes for a carbon monoxide alarm. That comes before both.
Why you were told otherwise
Usually not because anyone lied to you. Almost every claim in this category is technically true and incomplete, which is a much more durable technique.
- 'Kitchen air purifier' is a growing search term and marketing follows search terms.
- A purifier is a discretionary purchase you can make today; a ducted chimney is a fitting job you have to arrange.
- Chimney retailers rarely explain that recirculating models do nothing for combustion gases, because it would rule out their cheaper range.
- Nobody sells the highest-value change here, which is switching the exhaust on before you start cooking rather than when smoke appears.
What to do instead
A page that only says no is an opinion. This is the part that makes it useful.
- 1
Check whether your chimney ducts outdoors
This is the single most valuable thing to verify in an Indian kitchen. A recirculating chimney passes air through grease and carbon filters and returns it to the room, which leaves NO₂, CO and fine particulate exactly where they were.

Run the exhaust from before you light the hob
Free, and most of the achievable benefit is in the timing rather than the equipment. Leave it running ten minutes after you finish.

Cook on the rear burners and close the kitchen door
Capture efficiency is substantially higher at rear burners under the same hood, and a closed door contains the plume in one room rather than distributing it through the flat.

Put the purifier in the living room, not the kitchen
Once extraction is right, a purifier in the adjacent space handles what escapes. That is a sensible role for it.
