Introduction to Air Purifier

Air purifier is a product that can adsorb, decompose or transform various air pollutants and effectively improve the cleanliness of indoor air. They are used in the home, medical and industrial fields, with single-unit home air purifiers being the mainstream product in the home field. The most important function is to remove particles in the air, including allergens, indoor PM2.5, weather forecast, etc..

Principle of Air Purifier

Air purifier is mainly composed of motor, fan, air filter and other systems, its working principle is: the motor and fan inside the machine to make indoor air circulation flow, polluted air through the air filter inside the machine will be a variety of pollutants to remove or adsorption, some models of air purifiers will also be in the outlet of the installation of anion generator (when working in the anion generator in the high voltage to generate DC negative high voltage), the air will be The air is continuously ionized to produce a large number of negative ions, which are sent out by a microfan to form negative ion airflow, achieving the purpose of cleaning and purifying the air.
