With the intensification of air pollution, the purification technology required by air purifiers is also higher. From the current air purifier products on the market, purifier products are full of styles and functions, but from a technical point of view, almost all The purification methods adopted by air purifiers are nothing more than physical methods, electrostatic methods, negative ion methods, and composite methods. Because of the different working principles, these purification techniques have different ways of purifying pollutants, and the purification effects are all different.
First, the physical purification method
Mainly refers to the passive air purification method, also known as mechanical filter type filter, which generally includes two kinds of activated carbon filter and HEPA filter purification. It mainly uses air blower to pump air into the machine and then filters through the built-in filter. Air, can play a role in filtering dust, odor, disinfection and so on.
Second, electrostatic adsorption
This method refers to the continuous release of high-voltage static electricity from the electrostatic precipitator U.S.A., so that the dust and bacteria that come in with the air are positively charged, and then absorbed by the negative electricity level, and can filter dust smaller than cells, smoke, and protect the respiratory system. Reduce the risk of cancer. This purification method covers high-voltage electrostatic dust collection, electrostatic electret filter, electrostatic dust removal, classical sterilization and more.
Third, negative ion purification
The use of self-generated negative ions to purify the air, dust, deodorization, sterilization environment optimization of electrical appliances, and the difference between the traditional air purifier negative ion as a factor, take the initiative to attack the harmful substances in the air, is a need Consumable air purifier products.
Fourth, compound way
The working principle is that the motor and the fan in the machine make the indoor air circulate. The dirty air passes through the filter in the machine and removes or adsorbs various pollutants. The sterilizing technology of the purifier generates some oxygen and negative ions. Send out, actively capture pollutants in the air, achieve cleaning through multiple purifications, clean air.
The above is the principle of the 4 core purification of the air purifier. I believe we have already learned more about it. We hope to help with the purchase of air purifier products in the future.
