A range hood is an essential gadget in the kitchen

 A range hood is an essential gadget in the kitchen, and choosing the wrong one can be really frustrating. My previous cheap one made a buzzing noise whenever I used it. Cooking in the summer is already hot, and with this noise, my mood plummeted to the bottom.When choosing a range hood, there are several parameters to keep in mind. The noise level should not be too high, otherwise cooking will feel like a battle. The air volume should generally be above 20 cubic meters, as too much air volume will also result in high noise. For low-rise buildings with public flues, wind pressure is very important, and it should be chosen to be above 900Pa, otherwise the fumes will not be able to be discharged. Additionally, a self-cleaning function is necessary, otherwise it will cost 150-500 yuan to have someone clean it, which is both expensive and troublesome.
