What should I pay attention to when buying a range hood?
Buying a range hood requires the following considerations: ** 1. Basic functions ** 1. ** Smoke discharge rate or suction rate ** - Kitchen fumes are harmful to the human body, so you should choose a range hood with a large smoke exhaust rate, which can reduce indoor pollution and avoid adverse effects on the human respiratory system and body appearance, such as dark complexion, coughing, etc. 2. ** Negative pressure ** - Negative pressure was an important indicator of the range hood. The greater the negative pressure, the stronger the smoking ability. Different structures (such as side suction, top suction, European-style, etc.) of the range hood produce different "negative pressure zones", and the effect of the smoke suction is also different, so it is important to consider when purchasing. 3. ** Fat Separation Rate ** - According to the energy efficiency standards of the range hood industry, the grease separation degree should not be less than 80%. A higher degree of grease separation could separate the oil from the oil and collect it in the oil cup. If the degree of separation was too low, it would cause excessive oil deposits. 4. ** Wind volume ** - The exhaust air volume of the range hood on the market was between 13m cubic meters/min and 22m cubic meters/min. The best exhaust air volume for a general household kitchen was 15m cubic meters/min. However, if it was an open kitchen, a larger exhaust air volume was required, which should be determined according to the size and design of the kitchen. 5. ** Wind pressure ** - The wind pressure of the range hood on the market was generally around 300Pa. For safety reasons, one could choose a range hood with a wind pressure of more than 320Pa or an automatic pressurizing function. However, the higher the wind pressure, the better. Too high a wind pressure might mean greater noise, and many manufacturers had a false standard. ** 2. Quality of the product ** 1. ** Eligible product ** - It was necessary to pay attention to whether the range hood was qualified, that is, in line with the national listing standards. If you don't have the relevant certification, it's not recommended to buy it. Three-no products are easy to cause safety risks. 2. ** Brand and After-sales ** - It is recommended to choose a branded range hood product, which is more guaranteed in terms of quality and after-sales service. ** 3. User Experience ** 1. ** Noises ** - According to the relevant regulations, the noise level of the range hood should not exceed 65 - 68 decibels. The lower the noise level, the better. When buying, you can pay attention to the noise of the range hood, especially the front noise, and touch the outer shell to see if there is vibration. Give priority to a quiet and stable range hood. 2. ** Style ** - The style of the range hood needed to match the kitchen. If it did not match, it would be difficult to find the installation location. Not only would it affect the use, but it would also waste money. The shape and size of the kitchen had to be considered. ** 4. Mistakes to avoid ** 1. ** Avoiding brand premium ** - Although you get what you pay for, there was no need to blindly pursue high-priced range hoods. 2. ** Avoiding the wrong brands ** - Also, don't choose an inferior range hood for cheap. 3. ** Avoiding the "gimmick" function ** - The main function of the range hood was to absorb oil and smoke, and the fancy functions that came with it might be flashy. "Choose" was equally exciting. Everyone was welcome to read it!
