    Purification principle
    Airflow → Purification of primary effect → Air conditioning → Purification of intermediate effect → Air supply to fans → Pipes → Effective purification air outlet → Blow into the room → Bring away particles such as dust and bacteria → Return air shutters → Primary effect purification Repeat the above process to achieve purification purpose

    Physical purification method
    1. Adsorption Filtration-Activated Carbon Activated carbon is a porous carbonaceous material. It has a highly developed pore structure. The porous structure of activated carbon provides it with a large amount of surface area and can be fully contacted with gases (impurities). The unique adsorption performance of activated carbon makes it very easy to achieve the purpose of absorbing and collecting impurities. Just like magnetic force, all molecules have the disadvantage of mutual gravitation: ordinary activated carbon cannot adsorb all the toxic gases, and it has low efficiency and easy desorption.
    2.Mechanical filtration—HEPA (High efficiency particulate air Filter), which means high-efficiency air filter, a filter that meets the HEPA standard, and has an efficiency of 99.998% for 0.3 microns. The characteristic of the HEPA net is that the air can pass through , But the fine particles cannot pass. The HEPA filter consists of a stack of continuously folded back and forth sub-glass fiber membranes, forming a wavy gasket for placing and supporting the filtering boundary.
    Electrostatic purification
    Working principle: Adopt high-voltage electrostatic adsorption dust removal working principle. Electrostatic type is the working principle of high-voltage electrostatic adsorption dust removal. Under the action of high-voltage static electricity, the cathode line in the electrostatic field generates a corona discharge, and a large number of negative ions are generated in the corona layer. The negative ions continuously move to the anode under the effect of the electrostatic field. When the dust in the air passes through the electric field, the dust is charged by the collision of negative ions, and the charged dust is also affected by the electrostatic field, moves toward the anode (dust collector), and releases the charge when it reaches the anode.
    Disadvantages: It can remove flying dust (cannot remove toxic gas), its efficiency is lower and slower than mechanical type, and it is easy to produce ozone. This model has been rated as the Z difference purifier by the US market.
    Chemical purification method
    1. Photocatalytic method works: When air passes through a photocatalytic air purification device, the photocatalyst itself does not change under the irradiation of light, but can promote chemical reactions. Harmful substances in the air such as formaldehyde and benzene play a role in photocatalysis Degradation occurs, producing non-toxic and harmless substances, and bacteria in the air are also removed by ultraviolet light, so the air is purified. Disadvantages: Broad spectrum but requires low air flow rate, slow purification speed and some radiation to the human body. It is the depleted purification method in Europe and America.
    2. The working principle of formaldehyde scavenger: It is a chemical reaction between formaldehyde and formaldehyde to achieve the purpose of removing formaldehyde
    (1) Chemical reactions: chemical reactions with formaldehyde to generate carbon dioxide and water, such as ammonia;
    (2) Biological: It is made of biological agents that can react with formaldehyde, such as urea, soy protein, amino acids, etc .;
    (3) Plants: made of plant extracts, such as aloe vera, tea extract, etc .;
    (4) Closed class: It is made of film-forming substances, forming a thin film to prevent the release of formaldehyde, such as chitosan, liquid paraffin, etc. Disadvantages: First, the substances generated after the chemical reaction are likely to cause secondary pollution. The phenomenon of secondary detection exceeding the standard often occurs. Second, it is to absorb formaldehyde without changing the chemical composition and reduce the formaldehyde content in the air.
    3.Pharmaceutical, catalytic method --- The principle of cold catalyst essence: cold catalyst, also known as natural catalyst, is another new type of air purification material after photocatalyst deodorizing air purification material, which can catalyze reaction at normal temperature. Decomposes a variety of harmful and odorous gases into harmless and odorless substances at room temperature and pressure, transforms from simple physical adsorption to chemical adsorption, and decomposes while adsorbing, removing formaldehyde, benzene, xylene, toluene, TVOV and other harmful gases to generate Water and carbon dioxide, in the catalytic reaction process, the cold catalyst itself does not directly participate in the reaction, the cold catalyst does not change or lose after the reaction, and plays a long-term role. The cold catalyst itself is non-toxic, non-corrosive, non-combustible, and the reaction products are water and carbon dioxide, which does not generate secondary pollution, which greatly prolongs the service life of the adsorbent material.
    Other purification methods
    1.Washing the room quickly and effectively removes toxins, dust, smoke, odor, viruses, etc. in the room, and generates a lot of fresh oxygen.
    2. The negative ion method can reduce active oxygen (oxygen free radicals) produced by atmospheric pollutants, nitrogen oxides, cigarettes, etc. after contacting with harmful gases floating in the air, reducing the harm of excessive active oxygen to the human body; Neutralize the positively charged airborne dust and settle after no charge, so that the air is purified.
