There are certainly many opportunities to party with friends and relatives by the end of each year. However, some of our young friends talked about the party this year but we are somewhat discouraged because many people have resorted to strokes in the previous influenza tide and are inevitably inevitably going to parties during the New Year. There will be physical contact, this time is very prone to cross-infection of the flu virus.In fact, for the flu virus, the home simply put an air purifier can dispel the concerns of many small partners.
As an essential part of contemporary life, air purifiers play an important role in the health of your home environment. So, what are the benefits of different air purifiers? Here's what Xiaobian takes you through the benefits of air purifiers.
one, Activated carbon layer: adsorption filtration
Activated carbon is a porous carbonaceous material that has a highly developed pore structure. The porous structure of activated carbon provides a large amount of surface area for it to fully contact with gases (impurities), thereby giving the activated carbon its unique adsorption properties, Making it very easy to achieve the purpose of absorbing impurities collected just like magnetic force, all the molecules have mutual attraction, can absorb a lot of free state of harmful gases.
Second, HEPA network: mechanical filtration
HEPA (HighefficiencyparticulateairFilter), the Chinese meaning of high efficiency air filter to HEPA standard filter, the efficiency of 99.998% for the 0.3 micron, HEPA network is characterized by air can pass, but the small particles can not pass. HEPA filter It consists of a stack of sub-glass fiber membranes that are folded back and forth in succession to create a wavy gasket for placing and supporting the filter media.
Third, electrostatic purification
Working principle: The principle of high pressure electrostatic adsorption dust removal. Electrostatic is the use of high-pressure electrostatic adsorption dust removal principle. The electrostatic field of the cathode line in the role of high-pressure static electricity, resulting in corona discharge, corona layer in a large number of negative ions, Anion under the action of the electrostatic field, the constant movement to the anode.When the dust in the air through the electric field, the dust by the negative ions collide with the charge, charged with the dust also by the role of electrostatic field, the anode (dust collector ) Movement, the release of charge after reaching the anode. In simple terms is to use electrostatic adsorption of dust!
Fourth, the photocatalyst catalyst
How it works: When the air passes through the photocatalytic air purification device, the photocatalyst can not change itself under the irradiation of light, but it can promote the chemical reaction. The harmful substances in the air, such as formaldehyde and benzene, are degraded under the action of photocatalysis to generate Non-toxic and harmless substances, and bacteria in the air are also removed by UV light, the air is purified.
Five, formaldehyde scavenger method
How it works: The use of chemical substances and formaldehyde for chemical reactions, to achieve the purpose of removing formaldehyde.
1. Chemical Reactions: chemical reaction with formaldehyde to generate carbon dioxide and water, such as ammonia;
2. Biology: made of biological agents that react with formaldehyde, such as urea, soy protein, amino acids, etc .;
3. Plants: made from plant extracts, such as aloe, tea extract, etc .;
4. Closed category: made of film-forming material to form a film to prevent the release of formaldehyde, such as chitosan, liquid paraffin and so on.
