The principle of air purifier introduces

The results show that the recent continuous, large-scale strong haze contains a large amount of nitrogen-containing organic particulate matter, which is the main component of photochemical smog in Los Angeles in the last century. According to medical experts, haze weather can also induce a variety of diseases. Some netizens spit on Weibo, and now people can only go out wearing masks and use purifiers at home. Today we will look at the principle of the air purifier

Introduction to the principle of air purifier

The air purifier is mainly composed of a motor, a fan, an air filter and the like. The working principle is as follows: the motor and the fan in the machine circulate the indoor air, and the polluted air passes through the air filter in the machine to remove various pollutants. Or adsorption, some models of air purifiers will also be equipped with a negative ion generator at the air outlet (the high voltage in the negative ion generator generates DC negative high voltage when working), the air is continuously ionized, a large amount of negative ions are generated, and is sent by the micro fan. Form a negative ion airflow to achieve the purpose of cleaning and purifying the air.
