The role and function of the air purifier
Recently, due to the continuous development of the industrial industry, and ignoring the quality of air quality, the smog weather has followed since the beginning of winter, which has promoted the sales of air purifiers to increase year by year, and everyone is paying more and more attention to air quality. Because the smog contains a lot of bacteria and pollutants, which affect people’s health, let’s take a look at the role and function of the air purifier:
It can adsorb, decompose or convert various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, and other decoration pollution, bacteria, allergens, etc.).
Air purifiers are used in the home, medical, and industrial fields. Home-based home air purifiers are the mainstream products in the market. The main function is to remove particulate matter in the air, including allergens, indoor PM2.5, etc., while also solving due to renovation or
Air pollution problems of indoor and underground spaces and volatile organic compounds in vehicles caused by other reasons. The use of air purifiers to purify indoor air is an internationally recognized improvement in indoor airspace due to the persistence and uncertainty of the release of air pollutants in relatively closed spaces.
One of the methods of gas quality.
How the air purifier works:
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 purification
The device also installs a negative ion generator at the air outlet (the high voltage in the negative ion generator generates DC negative high voltage during operation), continuously ionizes the air, generates a large amount of negative ions, and is sent by the micro fan to form a negative ion airflow to clean and purify the air. the goal of.
1, passive adsorption filter purification principle (filter purification class):
The main principle of the passive air purifier is to use the fan to pump 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 screen is mainly divided into a particulate filter and an organic filter. One
The granular filter is further divided into a coarse filter and a fine particle filter. ,
2, active purification principle (no filter type):
The fundamental difference between the principle of the active air purifier and the passive air-purifying principle is that the active air purifier is free from the limitations of the fan and the filter screen, and is not passively waiting for the indoor air to be pumped into the purifier for filtration and purification. But effective and active to the air
The purification and sterilization factor is released, and the air is diffused to reach the corners of the room to clean the air without dead angle.
3, double purification class (active purification + passive purification):
This type of purifier combines passive purification technology with active purification technology.
