Extractor fans are electric devices that are used for the purpose of ventilating rooms or buildings. First let me tell you that you should practice caution at all times while dealing with electricity and electrical things. Little carelessness and even small mistakes can lead to big and deeper complications. Hence I would tell you to get in an electrician to fit an extractor fan in your kitchen.
Extractor fans installed in kitchens would get rid of cooking smells and bring in clean air. But as I said before please get an expert to do it for you because they would solve your problem very effectively. But I would also suggest that you install a thermostat with the extractor fan because then the fan would start throwing out hot air after it reaches a certain temperature and keep the atmosphere cool and clean.
