Japan, South Korea's air purifiers in succession for the China market in the late 1990s, thus contributing to the development of China's air purification technology. Our hospital indoor air disinfection, from before the 1980s, the use of bleach, disinfectant, ultraviolet disinfection, early 1990s, began to use ozone disinfection technology. . Abroad, in the 1960's, the United States using plasma technology, for indoor air sterilization to be successful, and in 1994, the FDA approved the listing. These disinfection, sterilization only in the absence of circumstances. Electrostatic purification works: ESP tungsten continuous release of High Voltage Electrostatic ceiling air disinfection machine offer, so with the air in the dust and bacteria are put positive charge ceiling air disinfection machine prices, then the negative electrode plate Adsorption. You can filter smaller than cell dust, smoke. Pros: Easy to use, does not use expensive replacement of consumables and can be sterilized electrostatic electrostatic tungsten release 6000 volt high voltage static electricity, and instantly kill bacteria, viruses and pollen... For the elimination of colds and infectious diseases more effective. Disadvantages: need to borrow special cleaning equipment; improper use or maintenance easily catch fire. And Wei developed a semiconductor disinfection purification technology can completely avoid the above problem, really fast ceiling air disinfection, sterilization perfectly efficient, clean, predictable details, please call the picture, thank you!
