Working Principle of Air Purifier

Air purifiers are mainly composed of motors, fans, air filters and other systems, and Its working principle is as follows: the motor and fan in the machine to circulate the indoor air flow, polluted air through the air filter inside the machine to remove or adsorption of various pollutants, some models of air purifier are equipped with anion generator at the air outlet (the high-voltage operation of the anion generator generates DC negative high voltage), which ionizes the air to generate a large number of anions, the breeze fan sent out, the formation of negative ion airflow, to clean, purify the air.  

1. Purification principle of passive adsorption filter type (filter screen purification class)
The main principle of passive air purifiers is: the air is pumped into the machine by the fan, and the air is filtered through the built-in filter, which can mainly play the role of filtering dust, odor, toxic gas and killing some bacteria. And the filter is mainly divided into particulate matter filter and organic filter. Particulate matter filter is divided into coarse effect filter, and fine particulate matter filter.  

2. Active purification principle (no filter type)
Active principle and principle of passive air purification of air purifiers fundamental difference is that the active air purifiers get rid of the limitation of the fan and mesh, not passively waiting for indoor air is pumped into the purifier filter purification, but effective and active purification sterilization factors that are released into the air, the characteristics of the spread through the air, Reach every corner of the room to clean the air without dead Angle. 

3. Double purification class (active purification + passive purification)
This purifier is actually a combination of passive purification technology and active purification technology.  

Nanjing Tong Chang Environment Tech Co., Ltd. Actively invests in the research and development of air purifier related products, is applying for a number of technology patents, and domestic and foreign leading research and development, industrial design team to achieve cooperation.
