As people's demand for quality of life is getting higher and higher, some manufacturers have developed air purifiers according to consumer demand, but many users do not know much about this kind of equipment, and do not know whether this thing is useful or not, this article will talk about the knowledge related to air purifiers.

Do air purifiers work?

The structure and principle of air purifier is not as complicated as imagined, it can indeed play a role in purifying the air, the most common air purifier has three parts, the power supply system, the wind system, and the most important filtration system, the power supply system for the air purifier to provide a stable power supply, while the wind system will be the indoor air inhalation or extraction, in the case of the wind system, these are inhaled or extracted by the air will be filtered by the "filtration system" to achieve the effect of purifying the air. Under the operation of the wind system, the inhaled or extracted air will be filtered by the "filtration system" to achieve the effect of air purification.

So, it's safe to say that no matter which type of air purifier you have, as long as the filtration system can function properly, it will do its job of purifying the air.

Types of "Filter Cartridges
The main factor that determines the effectiveness of the air purifier is the filter cartridge, which is divided into many kinds, such as photocatalyst, activated carbon, synthetic fiber, HEPA high-efficiency materials, negative ion generators, etc. Most air purifier cartridges on the market are made of these materials and apply the corresponding technology.

The most common air purifiers generally use photocatalysts, synthetic fibers, activated carbon three, slightly higher-end air purifiers will be used HEPA high-efficiency materials, anion generators as a "filter core" (just a general statement, some general references to technology, standards, etc.).

Types of materials for filter cartridges
Photocatalyst: chemical formula aside, let's talk about what is photocatalyst, photocatalyst is actually a semiconductor material, in the light source of irradiation can play a role in disinfection, sterilization, and this semiconductor material is chemically stable, long-term use of harmless to humans, and a long service life, with super hydrophilicity and self-purification.

The most widely used and common photocatalytic device in various fields is the "mosquito trap", and there are some air purifiers with this function.

Activated carbon: activated carbon is not carbon, carbon after special treatment will generate activated carbon, the surface of activated carbon has countless tiny, and invisible to the naked eye pores, these pores are calculated in nanometers, some manufacturers utilize this characteristic of activated carbon to make it into filters or filter cores, and combine it with air purifiers.

In addition, because activated carbon has the role of adsorption of formaldehyde, some businesses will also play the "formaldehyde" gimmick to promote air purifiers, but one thing we need to be clear, in addition to bacteria and harmful gases in the air, there are also visible to the naked eye, invisible dust, dust, these things will clog the activated carbon filter core, and activated carbon! Adsorption of formaldehyde is also limited, not "unlimited adsorption", unless the frequent replacement of activated carbon filter, or no role at all.

Synthetic Fiber: Synthetic fiber belongs to man-made materials, through artificial preparation, structural preparation and other processes, to create a close structure, complex mesh, sheet fabric, which will be made into a filter core, with some good permeability, filtration of auxiliary materials, made of air purifier cartridge.

Of course, this type of material will generally use environmentally friendly materials, will not cause harm to the human body, and a long service life, the family environment, the use of "low-end purifiers", are such synthetic fibers made of air filters, which are mainly used to purify the air of dust and fine dust.

HEPA high-efficiency materials: refers to the "HEPA standard" of the filter, any industry there are relevant standards, in fact, it and synthetic fibers are anon, are synthetic filters, but HEPA high-efficiency materials on the filter pore size, spacing requirements are higher, on the 0.1 ~ 0.3 microns. Dust filtration efficiency to reach 99.7% or more, to be considered qualified "HEPA high-efficiency materials.

Like the mask in the filter paper, belongs to a HEPA high-efficiency materials, according to the mask level of different levels of filter paper will also make a difference, it is not an exaggeration to say that all the air purifiers, for the dust removal effect of the best cartridge, is the HEPA high-efficiency materials.

Negative ion generator: this type of air filter belongs to the real high-tech products, it can not be called a filter, the so-called negative ion generator, we can understand it as "induced purification effect" of the device, the user opens this type of purifier, the negative ion generator will be a steady stream of negative ions generated by the air, the air anion will be negative ions with the air dust, smoke, viruses, bacteria, pollen, skin flakes and other substances charged, and then by a special device adsorption, collection, storage. The negative air ions will be charged with dust, soot, viruses, bacteria, pollen, skin flakes and other substances in the air, and then adsorbed, collected and stored by a special device.

However, it should be noted that the use of this type of air purifier, although it can play a role in purifying the air, but it is not suitable for long-term use, the use of a long time will lead to some of the problems of the person, such as headaches, low immunity and so on.

In summary, we can basically determine the materials and standards applied to the air purifier filtration system, thus proving that it is useful, but because of the different principles of purifying air and filtering air, there are still some differences, but I believe that you should know how to choose an air purifier after reading this article.
