What are the functions of an air purifier?

The multi-functional air purifier is developed on the basis of the traditional purifier, in addition to having the ability to detect and filter particles in the air with a diameter of less than microns); It can also detect odors and volatile organic compounds (VOCs) in the air, such as formaldehyde, toluene, etc., and filter and purify; At the same time, it also has the effect of antibacterial and sterilization; By emitting a high concentration of negative ions, so that we can have forest-like air in our office and home, because it integrates multiple functions, it has surpassed the traditional purification function, and is the development direction of a new generation of air purifiers, so it is called a multi-functional air purifier. The HEPA filter consists of a stack of sub-glass fiber membranes that are continuously folded back and forth, forming a wavy gasket to place and support the filtration boundary. It has strong ability to capture particles, small pore size, large adsorption capacity, high purification efficiency, and water absorption, and the particle purification rate for microns is as follows.

In other words, only 3 out of every 10,000 particles can penetrate the HEPA membrane. HEPA is an internationally recognized best high-efficiency filter material, which was originally used in nuclear energy research and protection, and is widely used in precision laboratories, pharmaceutical production, atomic research and surgery and other places that require high cleanliness. Activated carbon has better gas dynamic properties, small bulk density, large surface area, high adsorption efficiency, small wind resistance, long life, its principle is to rely on the developed pore structure and surface area of carbon itself, can be in contact with the surrounding air to a large extent, passive adsorption of pollutants into its own pores, so the larger the surface of activated carbon, the more developed pore structure, the stronger the adsorption capacity, theoretical research proves that the larger the molecular weight of harmful substances, the easier it is to be adsorbed by activated carbon, such as benzene molecular weight is 78, The molecular weight of formaldehyde is 30, and the adsorption of benzene will be stronger.

The biggest role of air purification is dust removal, which includes the removal of dust, dust, pollen, etc. For people with sensitive nasal passages, an empty purifier is a very necessary device. Sterilization is an important function of the negative ion purifier.

For example, the air purifier with negative ion function can effectively remove indoor bacteria, decompose indoor pollution without residue, and decompose pollutants such as formaldehyde and toluene into non-toxic and odorless carbon dioxide and water, which is safe and effective. Families who use air purifiers, especially those who choose negative ion air purifiers, generally report that the smoke smell in the room will dissipate after turning on the air purifiers. Decoration odors, such as some smells of plates, can also be purified.

The working principle of high-voltage electrostatic adsorption dust removal is adopted. The electrostatic type is the working principle of high-voltage electrostatic adsorption and dust removal. Under the action of high-voltage static electricity, the cathode wire in the electrostatic field produces corona discharge, and a large number of negative ions are produced in the corona layer, and the negative ions continue to move towards the anode under the action 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, moving towards the anode (dust collecting electrode), and releasing the charge after reaching the anode. To put it simply, it is to adsorb dust by means of static electricity. Note:

It can remove dust (can not remove toxic gases), the efficiency is lower and slower than mechanical type, and it is easy to produce ozone, this model is rated as the worst purifier in the U.S. market. There is no domestic technology that does not produce ozone under the action of static electricity.

What is an air purifierAir purifiers, also known as air cleaners, refer to products that can adsorb, decompose or transform various air pollutants and effectively improve air cleanliness.

What are the functions of an air purifierThe main function of the air purifier is to decompose the indoor polluted air and replace the fresh and healthy outdoor air with the indoor air, so as to ensure the indoor air quality and create a healthy and comfortable living environment. The main functions of air purifiers are to settle particles in the air, remove microorganisms and pollutants in the air, effectively eliminate odors, and quickly neutralize chemical gases.

As we all know, after the decoration of a new house, it is normal to leave some decoration pollution, among which formaldehyde, benzene, and other pollutants are particularly harmful to our body. Therefore, the treatment of formaldehyde and benzene has become a big problem to be faced when moving into a new house. The use of Rixin Yikang air purifier is one of the more reliable methods, so what is the function of the air purifier?

At the beginning of the dust removal air purifier into the Chinese market, it is to purify the dust, dust, pollen and other particles in the air.

Sterilization and sterilization are important functions of negative ion purifiers. For example, an air purifier with negative ion function can effectively remove bacteria in the room, especially with the UV lamp for double sterilization, which can effectively inactivate bacterial viruses and other microbial pollution in the indoor air.

Families who use air purifiers for deodorization are generally reported by citizens who choose negative ion air purifiers, and the smoke smell in the room will dissipate after turning on the air purifier. Decoration odors, such as some smells of plates, can also be purified.

The formaldehyde air purifier adsorbs formaldehyde through the adsorption of activated carbon filters, and with the development of science and technology, the treatment methods for formaldehyde are becoming more and more powerful, such as the ASNC nano mineral crystal adsorption system with an adsorption capacity of 9 times that of activated carbon, and then with the formaldehyde decomposition system, a new purification mode of adsorption + decomposition has been formed.

Of course, even if the air purifier has these functions, we must also control the selection of materials from the source when decorating to minimize the source of indoor air pollution. At the same time, in terms of decoration, it is advisable to focus on simple decoration and avoid excessive decoration. Only by taking a two-pronged approach can we better reduce decoration pollution and protect our health.

There are many functions, such as physics, chemistry, health, etc.; The specific functions are generally formaldehyde, antibacterial and antiviral, anti-allergic, dehumidifying, humidification, etc., and other basic functions are similar.

Purifying indoor air, removing formaldehyde, bacteria, disinfection and other functions are relatively common, and it is very suitable for children or the elderly to have one at home.

The main functions of air purifiers are sterilization, improving air quality, and eradicating other harmful substances.

1. Sterilization. The air contains a lot of bacteria, and air purifiers use negative ions and filter generators to effectively filter and degrade bacteria.

2. Improve air quality.

Most of the current air purifiers can generate negative ions, which can effectively improve the indoor oxygen content and enhance indoor comfort.

3. Eradicate other unwanted substances.

In addition to formaldehyde and haze, there are many unwanted substances and gases in the air, such as oil smoke, toluene, ammonia, etc. They can be completely filtered with an air purifier. Ensure that there is no peculiar smell and no pollution in the room.

Precautions for the use of air purifiers:

1. Stable placement.

The air purifier should be placed smoothly, the bottom and the contact surface should be flat, not placed against the wall or furniture, and it is best to keep a space of 1 meter around it to ensure the smooth entry and exit of the machine, so as to have a better purification effect.

2. Close the windows when the air pollution is serious.

When using an air purifier, if the outdoor air quality is poor, it is best to close the doors and windows immediately to form a closed type to improve the purification effect of the air purifier. In addition, if you are using a device with a humidification function, it is not recommended to use it in rainy seasons or in an environment with high temperatures, as it will reduce the purification effect.

3. Opening and use time.

The air travel silver Zheng air purifier does not need to be turned on every day, only when the air quality is not good, if the negative ion function is enabled, the corresponding function must be selected to produce negative oxygen ions. In addition, if the room is unoccupied, it can be closed or dismantled with the timer function.

The main function of an air purifier is to remove particulate matter in the air, including allergens, indoor, etc., and at the same time, it can also solve the problem of volatile organic compound air pollution caused by decoration or other reasons. Air purifiers can also adsorb, decompose or transform various air pollutants (generally including dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, etc.), effectively improve air cleanliness products, the main notice should be divided into household side of the elderly, commercial, industrial movement, industry, buildings.

The air purifier market is now relatively chaotic, whether it is useful to look at it from multiple angles: first of all, to understand its own needs, air purification mainly includes the purification of dust and organic pollutants two objects, for these two objects to take different ways, for example, the HEPA membrane used to treat particulate matter is no treatment capacity for formaldehyde, benzene, ammonia, electrostatic precipitator products can also only deal with particulate pollutants; Similarly, activated carbon is effective against benzene contaminants, but its ability to treat particulate matter is limited and uneconomical.

Secondly, it is necessary to find out whether the air environment around you will affect the health of your family, which is a national and international standard that can be referred to, and these standards are beyond doubt, as long as they exceed the standard, they will definitely have an impact! The more powerful it is, the greater the impact! The problem is in the measurements.

Now the instrument for measuring particulate matter is more compliant, cheap and effective, the difference is: the same degree of particulate matter exceedance, the damage caused to the human body in different regions is very different, Beijing lung cancer surpasses liver cancer is a realistic example, the reason is that there are ulterior reasons for particulate matter!

The choice of air purifier, if you want to deal with particulate pollutants, then as long as this device has a HEPA membrane, it is no problem, but to say that there is only this membrane, but to say that it can deal with organic pollutants is a lie. Some people say that negative ions can deal with organic pollutants, but it is useless to test them personally! At present, organic pollutants can be treated with activated carbon, alumina, photocatalysts, etc.

Among them, activated carbon and alumina are consumables, and the life of photocatalyst is relatively long, but there are technical problems that cannot be overcome, that is, it is easy to fall off and fail. Therefore, when choosing an air purifier, don't look at the publicity, but look at what technology it uses to solve the problem. The size of the processing capacity is directly related to the adequacy of the materials.

In general, the air in the home is really not very good now, and you need to use an air purifier, but you must prescribe the right medicine and not blindly follow it. There are also a lot of ways in this, which I can say clearly in these words, and those who have actual needs and want to know more can communicate with me.
