In this regard, the structure of the traditional filter screen air purifier is very simple, and the core components are the HEPA filter screen that needs to be replaced regularly and an exhaust fan. Consumers should not blindly pursue high-priced products. If consumers want better purification effect, it is recommended to choose negative ions (air purifier.
Compared with the traditional filter screen air purifier, the negative oxygen ion air purifier has high technology content and more advanced technology. Air negative ions, especially those with small particle size, can actively capture pollutants in the air and purify them more thoroughly.
In addition, consumers should also pay attention to the price when choosing negative ion air purifiers. If the price is too low, the negative ion release technology may not meet the standard. Of course, too high a price is not necessarily good. It is best to buy products with a price of more than 3000 yuan 10000 yuan.
Extended data:
Generation of ecological negative ions:
The ecological negative ion generator chip (patent No.20 122043390 1.6) consists of a ceramic piezoelectric negative ion generator and an ion converter (patent No.2010146958.8).
Ceramic piezoelectric transformer can suppress and eliminate the negative influence of positive ions generated by coil transformer used in traditional negative oxygen ion generator, and reduce the volume and thickness of negative oxygen ion generator. Ion converter is an upgraded version of negative ion converter, and its essence is the pulse frequency intensifier applied to negative ion generator.
The pulse frequency intensifier can effectively improve the pulse energy of negative ions, so that the air negative ion functional electric appliance adopting this technology can produce ecological negative oxygen ions with small particle size and high activity.
