I have a very noisy cooker hood which I don't like to use at it shakes and is very noisy even on setting one. Also the duct pipe has a long run which goes around a corner so I don't know how much extraction it actually does. When I am doing a lot of cooking I usually open the window or back door to let out smell and steam. Is it within regs if I have a good extractor fan installed in the wall. That is if I have to have a fan due to regs otherwise is it OK just to open the window or door.
Any advice would be appreciated. Thank you
