the process of purifying the effect and eliminating oil fumes such as sterilization lamps and high-efficiency activated carbon includes the following steps: first. the main reason in this process is to filter particulate matter such as oil fume, oil and grease; then walk into the purification device and the central part, the chemical function of the spray equipment and negative ion generator in the air will not produce domestic oxygen, negative ions and other substances, which can completely eliminate odors, kill bacteria, and remove harmful gases; at the end, the front high-efficiency activated carbon filter layer completely eliminates harmful gases and odors through deep purification.
