If it is used in the kitchen, it depends on the type of kitchen. If it is a small kitchen at home, you can only use a range hood. It is suggested that exhaust fans and range hoods should be used together in larger kitchens. If only one kind is installed, the range hood is relatively better than the range hood.
The function of the kitchen range hood is to discharge the steam and lampblack when cooking, which requires a relatively large air volume. General ventilators do not have such a large air volume, and the air volume of range hoods can reach more than 2000. There is an oil smoke filter screen in front of the centrifugal impeller, which can absorb the oil smoke produced by cooking, while the function of the exhaust fan is mainly to exhaust polluted air and hot air, which does not have the oil smoke filtering function and the air volume is not large.
