There are similarities and differences between oil fume purifier and range hood. The same point is that they are all pumping air to the outside, but there are many differences. For example, in terms of purification, the effect of the purifier is much better than that of the range hood, because the range hood can only exhaust smoke but can't effectively filter it, but in the purifier, it can effectively purify the lampblack and make it reach the emission standard, while the range hood can only simply control the oil, but can't effectively treat the lampblack, which can't meet the national emission standard; In terms of cleaning degree, the oil fume purifier adopts a filter, which is safe, hygienic, reliable and convenient to clean. Take Fangtai kitchen utensils and Shaanxi Daming Puwei as examples. In terms of air treatment, Fangtai's range hood is fast, but it has no filtering effect, while the oil fume purifier perfectly solves the problem, so I suggest you choose the person in charge of the production of oil fume purifier. Therefore, people who work in the catering industry can understand, and in recent years, the state has intensified its efforts to rectify the emission of polluted gases. It is recommended to use an oil fume purifier.
