Abstract: Kitchen fumes, as one of the three major sources of air pollution worldwide, pose a serious threat to human health. In order to the problem of fume filtration and purification, there is an urgent need to find a range hood with an ultra-high purification rate. By experimentally testing and comparing range hood with the new dynamic centrifugal interception device and other cooking fume exhaust devices with similar products on the market, it has been proven that the product with dynamic centrifugal interception device has better oil separation and filtration effects for fume particles with a diameter of less than PM₁₀. This not only improves the quality the cooking environment but also greatly reduces the impact on the external air environment, which is bound to lead the industry's new development momentum and provide strong support for green environmental, and sustainable development.

Key words: Oil fume suction device, Oil fume separation, Centrifugal dynamic separation
