decontaminate with six tier 1、air percolated by ULPA 2、sterilized by natrium and argentine Three Core Technologies： 1、 Air pollution monitoring technology: It owns the high sensitivity of monitoring harmful gasses:such as smoke, fog, alcohol, benzene, ammonia, carbon moncide etc. and it also controls the refining system automatic,. With the soonest and quickest recovery ability and perfect stability, the driver can be reminded always about the polluted air in the air. 2、 Nanometer Photocatalyst optical fusion technology: We use UR to fuse Titanium Dioxide and therefore creates the effect equaled to 1000 times of the optical fusion. During the process, it decomposes kinds of harmful or discomfort gasses: such as smoke, benzene, formaldehyde, carbon monoxide, dioxide carbon etc 3、 Plus and Minus Ion Refining and add-oxygen Technology: Refining air keeps simultaneous with killing virus. Plus and Minus Ion Refining generator can release Plus and Minus Ion in the car continusly to kill the possible virus thoroughly. At the same time, plenty of Minus Ion can improve the quality of the air. Six-Time Refine: 1、 ULPA Powerful Air filtering System; 2、 Nano Silver Sterilization; 3、 Active Carbon Delete Odour. 4、 UR kill Virus. 5、 Optical fusion kill virus and delete odour. 6、 Cooling Agent Kill Virus and Delete Odour.
