Air pollution is getting more and more serious. These air pollution poses a threat to people’s health. The appearance of air purifiers has made people see hope. Air purifiers can let people breathe fresh air. The air purifier is really good. Use it? Let’s take a look at the role of the air purifier.
Air purifier picture
Air purifiers, also known as “air cleaners”, air purifiers, purifiers, are capable of adsorbing, decomposing or converting various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.). , bacteria, allergens, etc., products that effectively improve air cleanliness, mainly divided into household, commercial, industrial, and building. There are many different technologies and media in the air purifier that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalytic technology, superstructure photomineralization technology, HEPA high efficiency filtration technology, electrostatic dust collection technology, etc.; material technology mainly includes: photocatalyst, activated carbon, Synthetic fiber, HEAP high efficiency material, negative ion generator, etc. The existing air purifiers are mostly compounded, that is, a plurality of purification technologies and material media are simultaneously used.
1. Purifying air: air negative ions make gas-soluble substances such as dust, smoke, pollen, droplets of water droplets and suspended microorganisms easy to accumulate, can oxidize with organic substances in the air to eliminate the odor generated by them, and thus have clean air, The role of improving environmental quality.
2. Sterilization: Air negative ions can be combined with bacteria, microbial viruses, etc. attached to the dust in the air to make them fall. Experimental studies have shown that air negative ions have a strong inhibitory effect on airborne microorganisms, so that the virus loses its ability to attack cells, thereby reducing the effect of bacteria purifying the air.
3. Eliminate static electricity: Static electricity is generally caused by ions with positive electric charge. Negative ions in the air will combine with positive ions to eliminate static electricity.
4. Biological effects: Experimental studies and clinical observations have shown that air negative ions have many biological effects on the body.
The above is the function of the indoor air purifier that Xiaobian has summarized for everyone. I hope that I can bring you help and help you better understand the air purifier. Air purifiers bring fresh air to people. Everyone should install an hot sale air purifier. There should be an air purifier installed in the home for the elderly and children.

What benefits will the air purifier bring to you in the future?
Everyone talks about the fact that the air purifier may not be more familiar with the name of the air conditioner.
The principle of the hot sale air purifier is similar to that of the air conditioner. It uses high wind rate to purify impurities such as micro-particles and dust in the air, so that harmful impurities and toxic gases in the air disappear. The air conditioner uses a high wind rate to rapidly cool the high-temperature air.
The air conditioner is purchased because of global warming, and the summer is too hot. If you adapt to the cool air with air conditioning, suddenly you will throw you in a place that is hot to cry, feel that you may not have air conditioning. It will be very difficult to see. The manufacture of air conditioners has brought a lot of comfort and convenience to people. It can be said that human life is closely related to the air. Under the dome, we reflect an environmental situation in our society today, but this The status quo is also a short time we can’t change, so there is the invention of household air purifiers. However, the prevalence of air purifiers is very low in China. Many people have denied the machine and prematurely denied it.
1. When you experience the newly renovated house and you are thinking about an urgent stay, you will be forced to stay in the strong formaldehyde smell.
You should really want to have a machine that can instantly purify your home air.
2. When the houses around you are industrial areas, no matter how you open the window every day, you still feel that the airflow is not good.
You may notice that the harm of the environment is actually related to yourself.
3. When you go to the Internet cafe, if you are a girl, you want to eat chicken or LOL, think about the hair that you just washed into the Internet cafe and have a nasty smell of smoke, and immediately stop,
Perhaps you can understand how important the air is. Generally, there are Internet cafes with girls’ zones. Others’ Internet fees are more expensive, indicating that some people are paying attention to this problem, the problem of air.
4. When you go to the public, everyone will ask for a ban on smoking. All these measures are focused on a good environment and need good air.
5. When you go to the hospital, do you not feel that this is a toxic gas when you smell strong disinfectant water, for fear that you will be infected with the virus for a second?
I can’t really smell the syrup of the hospital.

Is the air purifier effective? Is the air purifier useful?
Is the air purifier effective? Although air purifiers are so popular, they are so popular among consumers, but they still cause suspicion of bad people. The main function of air purifiers is to effectively improve the cleanliness of the air. Then the following small series will lead everyone to understand.
Is the air purifier effective?
The air purifier has a certain purifying effect on air impurities, but it does not have the ability to completely purify, because it can not circulate the air in the whole room, such as two rooms and one hall, and can only circulate air in one space for purification.
For example, when someone passes by, they will feel the wind caused by the air flow. If two people are far away, they will not feel the wind.
The air purifier can only make local air flow, so it can only be partially cleaned. Therefore, airborne impurities such as particulate matter (such as PM2.5) and decoration contaminants (such as formaldehyde) in the air cannot be completely removed.
Then, in the range where the air purifier can be purified, can air impurities be solved? The air purifier can solve the particulate matter of 0.3 micron and above in the air, but it cannot solve the decoration pollutants in the air.
The direct reason is that the purification speed of most air purifiers is less than the volatilization speed of the decoration pollution source. The fundamental reason is that the air purifier does not solve the volatilization source of gaseous decoration pollutants.
Is the air purifier useful?
For all new houses, formaldehyde will be produced after renovation. Many users know that the newly renovated houses cannot be checked in immediately. They must be ventilated for a long time to stay. If you want to stay in a new house in a short time. In fact, at this time you can consider putting an air purifier in the newly renovated house, so that the harmful gases such as formaldehyde in the new house can be quickly cleaned.
In fact, many people are now useful for table top HEPA air purifiers. There is a certain question in this question. The air purifier is mainly composed of a motor, a fan, and an air filter. When working, the motor and fan in the machine. The air in the room will flow, and the polluted air will be sucked into the machine, and the various contaminated areas in the air will be removed by the air filter inside the machine. Nowadays, there are many new air purifiers that use a negative ion generator in the outlet of the air purifier. It can continuously ionize the air and eventually produce a large amount of negative ions, which are then sent out to the machine through the fan. Achieve clean and clean air.
The general validity period of an household air purifier is about 12 months or a year, but the expiration date after opening is greatly reduced to about 3 to 6 months. The air purification product of the activated carbon adsorption function in the air purifier is very effective in a short period of time, but since the activated carbon needs to be replaced every two months or so, the cost will be high if used for a long time. Therefore, when selecting an air purifier, you should consider what kind of air purifier your family needs, which is cost-effective.

At present, there are two kinds of so-called air purifiers on the market, one is the filter type air purifier and the other is the ionized air purifier. In the end, I have not asked if I believe that the consumers will know it after using it. The disadvantage of the filter household air purifier is that the cost of consumables is high, the replacement of the filter screen is inconvenient, and it is easy to cause secondary pollution. The disadvantage of ionized air purifiers is that they are prone to ozone, and the so-called negative ion diffusion is almost ineffective. Why does the filter air purifier cause secondary pollution? In fact, this is not difficult to explain. It consists of a motor, fan, air filter and other systems. The motor and fan in the machine circulate indoor air. The polluted air passes through the air filter inside the machine to remove or adsorb various pollutants. The harmful substances are adsorbed on the filter net, and the harmful substances such as formaldehyde, toluene, ozone PM2.5, PM0.01, PM5, and PM10 are very high. Then, if it is not applicable, it will evaporate twice as the temperature changes. Therefore, it is necessary to change the filter frequently to form a high cost of consumables. So why does the ionized home air purifier say that the diffusion of negative ions is slow and easy to produce ozone? This is actually adding a so-called negative ion generator to the tuyere. The approximate effect is the same as the filter type. There is also a product called Senkong Machine (Forest Air Manufacturing Machine), which produces negative oxygen ions, which are medically known as “life vitamins”, “longevity” and “air vitamins”. principle “Forest air (negative oxygen ion) manufacturing system (machine)” that simulates the natural ecological environment. Designed in accordance with the principles of “Nature Ecology (Photocatalytic Nanotechnology), Lenal Effect and Water-borne Waterfall”. In the “nano-photocatalytic chamber”, it produces a vitamin-rich negative oxygen ion that is rich in people’s vitality, reaching or exceeding the levels of “negative oxygen ion” in many mountains and forests. Then what is negative oxygen ion? Negative oxygen ion refers to obtaining one or more electrons with negatively charged oxygen ions. Negative oxygen ions, known as “air vitamins”, are beneficial to the body’s physical and mental health. It mainly affects the human body’s physiological activities through the human nervous system and blood circulation.

As air quality declines, help them remove dust, pollutants, and harmful substances from the air so they can breathe. Maybe, there is even a few air purifiers in your home; maybe, when the air quality is poor, the first appliance you turn on after you go home is the air purifier. But, do you really know what the air purifiers do?
In fact, the so-called “air purification” is a very broad concept, it includes many aspects, so the role of air purifiers is also multifaceted:
1, can remove a lot of dust, particles, dust in the air, to avoid people sucking them into the body;
2, can remove formaldehyde, benzene, insecticides, aerosols, and other toxic substances in the air, to avoid physical discomfort and even poisoning after contact with the human body;
3, can remove the strange smell of tobacco, soot, animals, exhaust gas, etc. in the air, to ensure that the indoor air is fresh so that the people in the deep are refreshing.
Although the air purifier is rich in function and powerful, it can be greatly reduced if it is used improperly. Therefore, here I would like to share with you some tips on the use of air purifiers, hoping to give friends some useful references.
First of all, try to choose whether to open the hot sale air purifier depending on the air quality. If the outdoor air quality is OK, there is no need to use the air purifier for a long time. In addition, it is recommended that you open the air purifier in the dry winter and summer, and use it together with the humidifier to prevent excessive drying of the indoor air and cause discomfort to the human body.
Secondly, for the household air purifier in use, necessary maintenance and cleaning should be carried out. Especially when the filter screen is dirty or the dust collecting plate light is on, it is best to replace and clean it in the first time to avoid affecting the air. The normal operation of the purifier.
Third, the purifier with high-efficiency filtering should always check the indicator light when working. If the indicator light is on, you should replace the filter element in the first time. If there is no indicator light, you can directly check the filter element. If the color is black, you need to clean it in time.
See here, I believe everyone should have a certain understanding of the role of the air purifier and the precautions when using it. For more information about the brand of air purifier, please visit the brand of air purifier in 2018.

Air purifiers, also known as “air cleaners”, air purifiers, purifiers, are capable of adsorbing, decomposing or converting various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.). , bacteria, allergens, etc., products that effectively improve air cleanliness, mainly divided into household, commercial, industrial, and building. There are many different technologies and media in the air purifier that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalytic technology, superstructure photo mineralization technology, HEPA high efficiency filtration technology, electrostatic dust collection technology, etc.; material technology mainly includes: photocatalyst, activated carbon, Synthetic fiber, HEPA high-efficiency material, negative ion generator, etc. The existing air purifiers are mostly compounded, that is, a plurality of purification technologies and material media are simultaneously used.
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 household air purifiers will also be equipped with a negative ion generator at the air outlet (the high voltage in the negative ion generator generates DC negative high voltage when working), the air is continuously ionized, a large number of negative ions are generated, and is sent by the micro fan. The negative ion airflow is formed to achieve the purpose of cleaning and purifying the air. Passive adsorption filtration purification principle (filter purification) The main principle of the passive hot sele 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. The particulate filter is divided into a coarse filter and a fine particle filter. The quality of the fan and filter of this type of product determines the effect of air purification, and the location of the machine and the layout of the interior will also affect the purification effect. 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. It is an effective and active release of purification and sterilization factors into the air. Through the characteristics of air diffusion, it can reach the corners of the room to purify the air without dead angle. The technologies for purifying sterilization factors in the market mainly include silver ion technology, negative ion technology, low-temperature plasma technology, photocatalytic technology, and plasma ion group ion technology. The biggest defect of this kind of product is the problem of excessive ozone emission. Double purification class (active purification + passive purification) This type of purifier combines passive purification technology with active purification technology.
How to buy 1, choose the right purchase channel When purchasing an air purifier, it is recommended to purchase it in regular channels such as electrical stores, brand stores, and mainstream e-commerce websites. The first air purifier is sold in Taobao, Jingdong, Suning Tesco, Alibaba, official website, etc. For consumers who need to protect PM2.5, it is recommended to choose an air purifier with outstanding PM2.5 purification capability. Newly renovated homes can focus on air purifiers that have outstanding formaldehyde and toluene capabilities. The first air purifier has PM2.5 purification ability and formaldehyde removal function, so you can worry about it. 2, filtration technology The particulate pollutant filtering technology is mainly the HEPA filter. The quality of the HEPA filter is uneven. Some small brand filters have high filtration efficiency, but the resistance is high, the energy efficiency ratio is low, and it is easy to block and has a short life. It is recommended to use the deep dust-proof HEPA filter with the electrostatic resident. The electrostatic electret technology makes the non-woven fabrics have positive and negative electricity, which effectively captures the particles in the air. Many HEPA filters are said to have static electricity. Electret technology, but for technical reasons, many of the filter’s electret charges decay very quickly in a short period of time, resulting in reduced filtration efficiency and permanent guarantee that the electret efficiency is not attenuated. 3, pay attention to the applicable area or the amount of clean air (CADR) The strength of the purifying capacity of the air purifier is mainly determined by the applicable area and the amount of clean air (CADR: the rate of clean air provided). The relationship between the two is Applicable area = CADR × 0.1. The ability to purify other contaminants should be combined with the applicable area. [8] 4. Energy efficiency ratio and energy efficiency rating Air purifiers are usually used continuously for a long time. The energy efficiency ratio is an important indicator for measuring the purifying capacity and power consumption of air purifiers. It is worthy of attention. The first brand air purifier has a high energy efficiency ratio and energy efficiency rating, and the air purifier is very energy efficient, which can effectively reduce your cost of use.

Negative ion air purifier, artifacts that do not cause secondary pollution
The well-known filter-type air purifier absorbs dust or particles in the air by fan suction + filter filtering. The service life of the filter is generally about 3 months. After the filter is saturated, it is necessary to replace the new network in time. In order to maintain the original purification efficiency of the hot sale air purifier. However, due to different environmental pollution levels and different working hours, the replacement of the filter will not be timely. If the filter replacement is delayed, the pollutants are discharged again into the indoor air, causing secondary pollution.
In addition, electrostatic precipitator air purifiers also have secondary pollution problems. Due to the use of ionized air, ozone and nitrogen oxides, which are harmful to the human body, are generated, which brings secondary pollution to the room.
The negative ion air purifier is an innovative air purifier that emerges after the filter-type, electrostatic precipitator air purifier. The artificial generation of negative ions has gone through a long process. Most of the negative ion generators popular in the early market use the bipolar corona discharge technology and the unipolar electron injection technology to generate air negative ions. The negative ion concentration generated by this method is not high, the expansion performance is poor, and ozone is generated, causing secondary pollution.
