Central air conditioning --- Wei, an air purifier disinfection recent Health Ministry data show that China has more than 5 million central air conditioning return air using electronic air purifier prices, and 10% annual rate of increase. Ministry of Health focus on the use of central air conditioning inspection found excessive bacteria, and some use none of the 20-year pipeline cleaning. Therefore, the Ministry of Health issued a public places, air ventilation system health management approach, since March 1, 2006 implementation. Central air-conditioning for the market and have been used in air purification not considered return air electronic air purifier principle, when handled properly clean air return electronic air cleaner specifications that would result from the pipeline there are a lot of bacteria and viruses, and become a source of transmission of various infectious diseases. In order to prevent viruses, bacteria infection, the company developed a central air conditioning --- Wei, an air purifier disinfection, install the product in the delivery of central air conditioning, can effectively remove "viruses, bacteria, dust and harmful gases in the return air duct "Legionella and return air electronic air purifiers, air purifiers can not only achieve, but also in line with the Ministry of Health," Disinfection technical specifications "requirement. The products and supporting the use of central air conditioning systems. Not only greatly extend the central air-conditioning efficiency filter life, and can effectively reduce the central air conditioning running costs and maintenance expenses. Central air conditioning is the ideal accessory indoor air disinfection and purification devices.
