Are recirculation extractor hoods good?
I am looking for a extractor hood, and I see that there exist ones with air recirculation, so a pipe to lead the smoke/greasy air away is not needed.
So I wonder, how good are these?
Can they really clean the smoke/greasy air they pull in?
Best Answer
If you have a gas stove, you need a hood to send the exhaust outside. One that recirculates is not sufficient.
In my experience, the recirculator hoods work OK if you're not doing a lot of cooking. If you do, however, you'll end up with a nasty, greasy dusty coating on everything in your kitchen. I wouldn't bother with a recirculation hood if you ever cook things that involve grease or smoke. For someone who mostly heats up processed foods, it's probably good enough.

Quick Answer about "Are recirculation extractor hoods good?"
The Recirculation Hood Recirculation/self-circulating cooker hoods are often much cheaper than extraction hoods because they don't include ducting. However, they are less effective at dealing with smells, grease, and smoke because they have to process the air, and inevitably they don't do that 100% perfectly.Is extraction better than recirculation?
Although extraction hoods are more effective than recirculation hoods, they are more expensive to install due to all the extra requirements. A recirculation hood pushes the air up through filters inside, which then remove any moisture and smells before the air is then reintroduced into your kitchen.What is the difference between extraction and recirculation cooker hood?
Extraction is when the stale air is extracted out of the room through ducting in an outside wall to the air outside. Recirculation is used when it is not possible to duct out through an outside wall. The air is sucked into the hood, filtered, purified and pumped back into the room.What is the difference between ducted and recirculation?
With ducted hoods, air is extracted from the kitchen through a pipe that leads from the hood to an outside vent, whereas with recirculating hoods, air is extracted through a filtration system built into the hood, working to remove any grease and odour from the air before releasing it back into the kitchen.Does a recirculating hood need a vent?
Recirculating hoods simply recirculate air inside the home instead of pulling the greasy cooking exhaust and venting it outside the home, which is never ideal. A recirculating hood can also be noisier than ducted models; they often require much more fan power.What is a Recirculating Range Hood?- What is a Ductless Range Hood?

Answer 2
In some kitchens external exhaust just cannot be done e.g. a flat in a block of flats, with shared ventilation shaft. In such case the choice is: recirculation hood or no hood at all. In such case the former may be better that nothing, as it catches at least a bit of the unwanted particles and odors, provided the filters are regularly replaced.
Answer 3
Burning gas produces noxious gases such as carbon monoxide and nitrogen dioxide that recirculating hoods do not remove.
Ducted hoods can be made quieter by locating the extractor fan at the far end of the ducting, away from the kitchen.
Recirculating hoods require regular replacement of their carbon filters, meaning expense. Ducted hoods don't have or require filters.
Because of the carbon filters in recirculating hoods they can not achieve the airflow ducted hoods can for equivalent motor sizes. If you're doing lots of frying or high heat wok cooking, your hood must be sufficiently capable or you will just get a horrible nasty grease film EVERYWHERE. This is indeed a fire hazard with under-spec'd extraction often being the cause of Chinese restaurants burning down.
Answer 4
Depending on the brand/model you purchase you may not have to buy replacement filters, but instead clean them in the dishwasher and/or by baking them in oven.
