Selection Criteria For Range Hoods

1. Smoke exhaust rate

First of all, choose the one with high smoke emission rate. Kitchen fumes can cause harm to the human respiratory system. According to data, deaths from respiratory diseases account for the first cause of death in China. Soot-type fluoride poisoning and arsenic poisoning have become endemic diseases of residents in some areas. The purpose of installing a range hood is to remove the fumes during cooking and reduce indoor pollution. Therefore, when choosing a model, you must first choose the one with high fume extraction efficiency.

2. Negative pressure

Second, choose a large negative pressure. Because the greater the negative pressure of the range hood, the stronger the smoking ability. As you mentioned, the range hoods on the market are divided into flat type, semi{{0}}deep type, deep type and cabinet type, etc. They have different "negative pressure areas" due to different structures. Most deep type range hoods The negative pressure area of the hood is about 0.14 cubic meters, and its smoke exhaust efficiency is about 60 percent . The negative pressure area of the cabinet range hood is about 0.32 cubic meters, and the smoke exhaust efficiency is greater than 95 percent . However, because the cabinet type range hood adopts the form of three-sided closed, it looks luxurious without the hanging type in appearance.
