What it the real air purifier?
The best technology of air processing as follows: it won't cause the second-pollution but high-purified technology
the extrinsic circulation of Air Purifier ,by using the normal technology, has broken the traditional intrinsic circulation of air process. The first one adopted five-motor, multi-use, PC-control and filter with self-maintenance.
The nature air go through the Air Purifier by triple purification, firstly to remove the sand and dust from air outside, then by releasing anion and ultrasonic atomized humidifying ,and also using photocatalyst sterilization, and finally extrinsic air circulation forced the various of harmful gases and dust to be out of room, thus to make indoor room full of humidity and oxygen
On current market, most of Air Purifier belongs to intrinsic circulated air processor ,it means to convert or absorb only but without exchanging fresh air , thus very likely to cause the failure and secondary pollution. So people need to replace or wash filter regularly ,but not easy to operate it. While inside of room , it will be short of oxygen especially when the filter is clogging or the sterilization is failed , but people thought of the machine was still working well , this will cause misunderstanding and be harmful to their health
