As the air is polluted to varying degrees, both indoor and outdoor air will be mixed with many impurities and particles. Whether it is formaldehyde, bacteria, PM2.5 or viruses in the air in the indoor environment, it threatens our respiratory safety. At present, most air purifiers only purify, deodorize and are effective for PM2.5, but only a few professional purifiers are targeted for in addition to formaldehyde, and even fewer air purifiers with sterilization and disinfection functions. Transmex air purifier is a white fox design that combines people's existing needs and has newly developed sterilization and disinfection effects on the original basis of air purifier. The transfer element air purifier uses a coarse-effect filter and a high-efficiency filter in combination with activated carbon, which can efficiently filter particles, dust, and PM2.5 in the air, and has very good smoke removal and dust removal effects; it is matched with a ceramic filter There are six ultraviolet lamps that can catalyze and assist sterilization, which can decompose formaldehyde, and the sterilization rate can reach 99.94%. The air purifier is equipped with human body induction control (MSS), which can adjust the wind speed mode by waving at 3cm above the sensor to reduce bacterial cross infection. The air purifier is divided into weak wind mode, strong wind mode and switching mode of startup and shutdown. The default mode is weak wind mode when startup is started, and high-speed snail fan is adopted without noise. After startup, the negative ion lamp lights up and starts to work; when the air purifier is running, it can also display the humidity and air quality in the current ambient air in real time, and display the air quality index through indicator lights of different colors. The air purifier has simple appearance design, small size, convenient to carry, simple operation, no noise generation, and is suitable for different life scenes. There are three different colors of blue, deep space gray and silver to choose from, which can meet the needs of different users.
