Any experiences (good or bad) out there with cooker hoods?
I don't like recirc models, It will have to extract vertically through roof
of bungalow.
Hob is Induction 4 ring .

What should the extraction rate be?
Any recommendations re Make & Model.?
Filters single/double /grease/carbon /metal?
Outlet size100mm / 150mm?
Tips on kitchen ventilation and extraction generally, should I try and
create negative pressure in kitchen?

I would be grateful for any comments on the above.
Regards
Tom
