OEM/ODM air purifier manufacturers believe that the air purifier is mainly composed of motors, fans, air filters and other systems. Its working principle is: the motor and fan in the machine circulate the indoor air, and the polluted air passes through the air filter in the machine Finally, various pollutants are removed or adsorbed. Some types of air purifiers will also install negative ion generators at the air outlets to continuously ionize the air and generate a large number of negative ions, which are sent out by micro fans to form negative ion airflow to achieve clean, The purpose of purifying the air.

　　1. OEM/ODM air purifier manufacturers passive adsorption filter purification principle (filter purification)

　　OEM/ODM air purifier manufacturers believe that the main principle of passive air purifiers is: use a fan to draw air into the machine, and filter the air through the built-in filter, which can mainly filter dust, odor, toxic gas and kill some bacteria. . The filter is mainly divided into: particulate filter and organic filter.

　　2. OEM/ODM air purifier manufacturers active purification principle (without filter)

　　The fundamental difference between the principle of active air purifiers and passive air purifiers is that active air purifiers get rid of the restrictions of fans and filters, instead of passively waiting for indoor air to be pumped into the purifier for filtration and purification. Instead, it effectively and actively releases the purification and sterilization factors into the air. Through the characteristics of air diffusion, it can reach every corner of the room to purify the air without dead ends.

　　3. OEM/ODM air purifier manufacturers double purification (active purification + passive purification)

　　This kind of purifier is actually a combination of passive purification technology and active purification technology.
