An oil fume purifier is a device that can effectively remove oil fumes and odors from places such as kitchens and restaurants and improve air quality. The principle is mainly based on electric fields, mechanical filtration, and chemical adsorption. 
The principle of electric field is to use the principle of electrostatic adsorption to charge the particles in the oil smoke and adsorb them by the electrode. Mechanical filtration is to intercept the particulate matter in the oil smoke through mechanical devices such as filter screens or filter cartridges. Chemical adsorption is the use of adsorbents to adsorb harmful substances in oil smoke, thereby separating them from the air. In the operation process of the oil fume purifier, the particles in the oil smoke are first charged through the electric field principle, and then these particles are intercepted by mechanical filtration. Finally, chemisorption separates these harmful substances from the air. After these three treatments, the harmful substances in the oil smoke are effectively removed, thereby improving the air quality. 
In addition to the above principles, oil fume purifiers also have the characteristics of low noise, easy cleaning and maintenance. At the same time, its efficient purification ability has also been widely recognized. In homes and commercial places, oil fume purifiers have become one of the must-have devices. 
In conclusion, the working principle of oil fume purifiers is mainly based on electric fields, mechanical filtration, and chemical adsorption. Through the synergy of these three methods, it can effectively remove oil smoke and odor and improve air quality. In modern homes and commercial places, oil fume purifiers have become one of the indispensable equipment to create a healthier and more comfortable environment for people.
