The HG mechanical metal cyclone aerosol separator can effectively remove large and medium-sized particles and can be cleaned in a dishwasher The CFW fume separator with an invention patent can effectively deal with particles of 5 microns and above with an efficiency as high as 99%. (Optional The grade of the disposable pre-filter is M grade. ESP (Electrostatic Precipitator) can operate with high efficiency. ESP induces static charges on the particles passing through it and then collects them on the collection plate that generates a magnetic field. ESP is highly effective against fine particles, including grease particles and steam, and can be reused after cleaning. (Optional F-class medium-efficiency filters effectively collect cooking oil fume particles. (Optional High-efficiency H-class filter, with a rated DOP of 95% for 0.3-micron aerosol. It is used to remove ultrafine particles mainly present in smoke. Some of the odors are carried by oil particles, water vapor and smoke. They were completely removed by the previous filtering step. The remaining odors, especially VOCs, can be effectively removed through the combination of activated carbon and chemical particles. First, the gas is removed through adsorption. Then, the odor is significantly reduced through adsorption, absorption and chemical reactions.
