There are both good and bad exhaust fans and range hoods. The best way is to match range hoods and range hoods, which is safer. Moreover, the distance between the lampblack machine and the pot is not as close as that of the oil-free stove, so there will be little lampblack when two exhaust fans are equipped with a lampblack machine, at least in my home now. The range hoods are beautiful, and the more range hoods, the higher the cost performance. Large suction, practical and easy to clean.
