How does an air purifier solve indoor air pollution problems?
Solving the growing problem of indoor air pollution through air purifiers is a common understanding of today’s society. However, it is estimated that many people can’t answer the question of how air purifiers solve various air pollution problems. So, how is the problem of indoor air pollution generated? How does an air purifier solve indoor air pollution problems? Unlike most people think, the main pollutants causing indoor air pollution problems are not dust pollutants or gaseous pollutants such as formaldehyde, but biological pollutants. Biological pollutants are mainly composed of pathogenic microorganisms. In outdoor environments, these pathogenic microorganisms are not affected too much by the sun, the gas flow, and the bactericidal plants, but they are crowded, dark and ventilated. It is easy to breed and breed in a bad indoor environment, especially in summer. The reason why air purifiers can solve indoor air pollution problems is that most of the air purifiers are equipped with ozone and ultraviolet disinfection technology inside, which has a good killing function for indoor bacteria and germs. At the same time, the air purifier with high-efficiency filtration and electrostatic adsorption function can adsorb the pathogenic microorganisms attached to the inhalable particulate matter in the air and kill them, thereby completely preventing the pathogenic microorganisms from harming human health. Of course, the current mainstream air purifier can only kill a few of the main pathogenic microorganisms, such as tuberculosis, diphtheria, hemolytic streptococcus and so on. For most pathogenic microorganisms that are not common pathogens, mainstream ozone and UV disinfection techniques are not reliable. However, along with the discovery and application of bio-antibacterial peptides, the ATP HEPA antibacterial peptide filter has solved this problem well. The antibacterial peptide originally refers to a kind of basic polypeptide substance with an antibacterial activity which is induced by insects, and has a molecular weight of about 2000-7000 and consists of 20-60 amino acid residues. Most of these active peptides are characterized by strong alkalinity, thermal stability, and broad-spectrum antibacterial properties. In the years after 1980, people have discovered and isolated polypeptides with antibacterial activity from bacteria, fungi, amphibians, insects, higher plants, mammals and even humans. After entering the 21st century, antibacterial peptides have officially been applied to the field of air purifiers as a means to more effectively solve indoor air biological pollution problems. However, due to the new technology, there are not many air purifier products currently using ATP HEPA antibacterial peptide filters.

There are several main factors to consider when choosing a particulate cleaner, including the purification technology used in the purifier, the efficiency of the filter, the amount of clean air, the life of the purifier, the way the air is used, and the ease of use.
Particulate purification technology prefers simple physical removal. The safer and more efficient technology is the HEPA network and activated carbon adsorption. Electrostatic dust removal and negative ion technology will produce ozone. Although ozone can kill bacteria, viruses, and oxidize and decompose volatile organic compounds, excessive ozone can affect the respiratory system, causing respiratory diseases such as asthma, and can cause cancer in severe cases.
For HEPA technology, different filter grades have different purification effects. The higher the HEPA network grade, the smaller the particle size of the particles that can be filtered, and the better the filtration effect. However, the high filtration efficiency brings about a large wind resistance. The air purifier pays attention not only to the single filtration effect but also because the filtered air is recycled again. The filter has a high grade, although the single filtration efficiency is high, a higher power motor and a larger volume are required, so the higher the better, the better. Of course, the filtration efficiency should not be too low, otherwise, the final purification effect will be limited even if the cycle number is high.
HEPA’s ability to clean air is identified by Clean Air Output Rate (CADR), which is the ratio of clean air output by air purifiers obtained by the American Association of Home Appliance Manufacturers (AHAM) according to strict testing standards. The higher the CADR value, the greater the amount of clean air output per unit time by the purifier. However, the higher the CADR, the higher the noise, power consumption, volume, and price of the purifier. The daytime ambient noise we usually live in is 35 decibels. More than 50 decibels affect sleep and rest, and more than 70 decibels can interfere with normal conversations. High CADR purifier, the noise can reach 70 decibels in strong wind mode, even in the sleep mode, the noise is more than 40 decibels. Therefore, daily use does not have to place too much emphasis on high CADR. The manufacturer will mark the CADR value in the purifier parameters, or convert this parameter into a value suitable for purifying the room area. When purchasing, we only need to consider whether the clean area of the air purifier matches the room area. Similar to our choice of air conditioning based on the room area for cooling or heating.
The life of the purifier refers to the length of time during which the purification efficiency is maintained, that is, the effective service life of the purified material. It is obviously better to replace it after using it for half a year. The life of the purifier is related to the material and area of the filter itself, and also related to the CADR value of the purifier. Of course, continuous high pollution will shorten the service life. In the new national standards for purifiers, purifier life is expressed in terms of cumulative purification (CCM), which refers to the total amount of fine particles that the purifier can remove. Above this value, the purifier will fail. Generally, when the CCM value is approached, the purification efficiency has decreased, the wind resistance of the filter screen has increased, and the CADR is also decreasing. At this time, the filter screen should be replaced in time.
The way of entering and exiting the wind is also a problem to be paid attention to when selecting a purifier. The wind in the back – the front air outlet mode, easily leads to dust on the floor in front of the purifier, which increases the amount of dust in the indoor air. Below or behind the wind – above the airway, the dust on the floor can be sucked into the air purifier to remove the new air from above, the fine particles removal effect is better.
Many purifiers have the function of displaying the concentration of fine particles in the air, or roughly use “excellent, good, medium, and poor” to display indoor air quality. But for a general purifier, look at the changing trend of air quality, and don’t have to worry too much about the specific value displayed. Because the price of the household purifier itself is between 1,000 yuan and 10,000 yuan, the instrument that can accurately measure the concentration of particulate matter is worth at least tens of thousands of yuan.
Proper use of air purifier
When using an air purifier, first think about who to use and where to use it. It is generally preferred to target sensitive people, such as the elderly, children, pregnant women and people with respiratory diseases, in the bedroom and living room where people stay the longest in their daily lives.
The core filter of the air purifier is limited by the size of the machine and cannot be made very large. In the case where the total removal efficiency is constant, it is better to divide into several small purifiers in a room of suitable area, which is better than using a large purifier to process several rooms at the same time. In particular, the mode of airflow is complicated due to the structural layout of multiple rooms and the placement of furniture. It is better to let the air purifier fan handle the simple airflow effect. Otherwise, it is possible that the fine particles have not yet reached the air inlet of the purifier, and it is unknown where the airflow drifts. If only one large purifier is used, although the purification effect near the machine will be better, the effect of other rooms may not be ideal.
The location where the air purifier is placed is as close as possible to the source of contamination so that contaminants can be efficiently removed at close range. For example, a purifier for removing cigarette smoke can be closer to the smoker. However, the air purifier has a strong air intake and an air outlet, so it should not be too close to the person’s head position to avoid direct airflow to the face. When outdoor pollution is serious, the concentration of particulate matter near the doors and windows will be relatively high, and the air purifier can be placed in these places. If there is no clear source of pollution in the room, it is best to place the purifier as close as possible to the middle of the house, not to the wall or furniture. Keeping a sufficient distance from the wall can reduce the turbulent airflow and affect the purification effect.
It should be noted that the purification capacity of the air purifier is limited. Under normal working conditions, it can have a more obvious purification effect for a relatively closed room; if the room is not tightly sealed, the outdoor pollutants will infiltrate continuously, and the purification effect will be greatly reduced. Just like when using an air conditioner, the effect of opening the air conditioner and opening the air conditioner at the same time is definitely much worse than closing the window. Of course, if the outdoor air quality is good, it is best to use natural ventilation to purify the indoor air.
When using the air purifier, you need to pay attention to the core components of the purifier – the filter element and the filter. The effective life expectancy should be replaced in time, otherwise, the expected purification effect will not be achieved. The fine particles enriched in the filter element are where the dirt is trapped. If it is not removed in time, there is a hidden danger of secondary pollution.

The misty day made the air purifier fire. However, the purifier market is mixed, and various slogans such as “efficient removal of PM2.5” and “removal of formaldehyde 99%” make consumers both excited and hesitant. Are these prices tens of thousands of purifiers really useful? To this end, the National Indoor Interior-Environment and Environmental Product Quality Supervision and Inspection Center made the first assessment of the performance of China’s air purifiers. The experimental results show that seven air purifiers claiming to have formaldehyde removal function are basically ineffective. The best effect of a purifier, the clean air volume (CADR) value of 29m3 / h, according to this data, in a 15 square meter room, boot for 1 hour, in theory, the formaldehyde reduction rate in the air is also less than 50 %, in the case of formaldehyde release indoors, the actual use effect will be even worse. It can be said that most of the air purifiers on the market claim to remove formaldehyde is only a selling point. In this regard, the national air purifier standard drafter, China National Center for Disease Control and Prevention researcher Chen Liexian and the director of the National Indoor Interior-Environment and Environmental Product Quality Supervision and Inspection Center Song Guangsheng reminded everyone that the following issues should be noted when purchasing and using air purifiers: Be wary of the “removal rate” trap. Some merchants take the opportunity to use the “removal rate” to mislead consumers. Those air purifiers with a “removal rate” of 99.9% formaldehyde purchased at a large price may be “comfort products” or even “garbage” products. These products are used indoors where formaldehyde is exceeded, no matter how long it lasts, there is no significant effect. The “removal rate” is difficult to reflect the true purification ability of the product due to factors such as the volume of the test chamber, running time and natural attenuation. According to the national standard GB/T18801 “Air Purifier”, the performance index of the air purifier should be expressed as “clean air volume” (CADR), expressed in m3 / h. When consumers purchase, they can directly check the CADR value of PM2.5, benzene, formaldehyde or volatile organic compounds (VOCs) in the air purifier, so that their performance can be seen at a glance. Need to be reminded that if the use area is greater than 10 square meters, the CADR value of removing any kind of pollutants should be greater than 60m3 / h, otherwise there will be no significant effect. Shop as needed. In general, air purifiers can remove one or more of the chemical, biological and radioactive pollutants in indoor air, and consumers should choose according to their own needs. Households with new renovations and new furniture purchases, homes close to highways and outdoor chemical contaminants should choose an air purifier that removes chemical contaminants. For families with children and chronic patients, it is best to choose products that have the function of purifying biological pollution.

Can’t tell the central air conditioning, fresh air system, air purifier? This tells you
Since winter The sky is gray Outdoor air quality is worrying The recent sudden cooling of the weather also forced the dog to hide indoors all day. I don’t want to go out with air conditioning I don’t want to open the window for anything. But time is long, kitchen fumes, decoration pollution There is also exhaled carbon dioxide But let the dog be groggy every day.
After all, it is a pet The dizzy dog succeeded in attracting the attention of the next lady. “Dog, the fresh air system know?” “What is the fresh air system? Is that the air purifier similar to the central air conditioner? ”
“NoNoNo, central air conditioning, air purifier, and fresh air system But three different things.” 💡 Do you have the same question as to the dog? Then take the time to eat an apple and study together.
Central air conditioning: indoor temperature regulation
Air conditioning is one of the most common appliances in our lives. As a northern dog, the dog can only rely on air conditioning in the south. Central air conditioning is also a type of air conditioning Is by a host through the air duct over the wind or hot and cold water pipe Connect multiple ends to control different rooms Air conditioning system for indoor air conditioning purposes Simply put, it is installed inside the ceiling. An invisible air conditioner that intelligently controls multiple rooms
Central air conditioning, rapid cooling, good cooling effect And the air is gentle and even In the hot summer and cold winter Can bring the comfortable indoor temperature However, the main function of central air conditioning is the adjustment of indoor temperature. Generally speaking, there is no effect of improving indoor air quality.
Air Purifier: Filtering indoor air
The air purifier is purified by internal circulation adsorption filtration. It can directly filter particulate matter in the air like a sieve Then produce clean air quickly and efficiently
Fresh air system: indoor and outdoor air circulation
Many people think that the fresh air system is Combination of air purifier and central air conditioner Actually not The core function of the fresh air system is to achieve the circulation of indoor and outdoor air. Fresh air system is powered by the air supply system and exhaust system a set of independent air handling systems When using the fresh air system Indoor turbid air is discharged to the outside through the exhaust vent Outdoor fresh air enters the room through the filter box and air inlet Thereby ensuring the circulation of indoor air Achieve ventilation and ventilation without opening the window It should be noted that the fresh air system does not have the function of temperature regulation. Cannot adjust the indoor temperature
Fresh air system is the same as an indoor air purifier Has the effect of improving indoor air quality The most fundamental difference between the two is: ✔The air purifier is a circulating filter to purify the air inside the house The new air system realizes indoor and outdoor air circulation through the exhaust and air supply ducts, and at the same time purifies the air that is sent in, and realizes full heat exchange.
The fresh air system currently on the market can be divided into Pipeline fresh air system (central fresh air) and ductless fresh air system
Non-pipeline new fans include wall-mounted new fans and wall-type new fans The wall-mounted fan is mounted on the wall Simple installation, small space occupation, not affected by the renovation Wall-mounted machines can also be installed in renovated houses.
Wall-type new fan adopts the installation method of punching holes in the wall The ventilation concept of the wall-type new fan is continuous ventilation for 24 hours. The air volume is generally small and the noise is very small.
In the Panasonic fresh air system, the system is usually built with a total heat exchanger. So what is a total heat exchanger?
The total heat exchanger is a kind of Fresh air and exhaust ventilation equipment The core component of Panasonic’s total heat exchanger is the heat exchange element. Dirty air discharged indoors and fresh air sent in outdoors Exchange of temperature and humidity by heat exchange of protons Thereby achieving the effect of ventilation And can maintain indoor temperature and humidity stability

The air purifier industry is still in a period of adjustment.
In 2018, due to the overall tightening of China’s macro environment and real estate adjustment, the overall growth of China’s home appliance market was under pressure. Relatively speaking, the performance of the health appliance industry was acceptable, but the purifier was absent. The brutal growth of the air purifier market stems from the fact that five or six years ago, the purifier market has grown from smoggy weather since it became a “pig of pigs”. In order to fight against smog, people have purchased air purifiers to ensure the air quality inside the house.
At the same time, since the issuance of the “Air Pollution Prevention and Control Action Plan” in 2013, 31 provinces (autonomous regions and municipalities) across the country have continuously increased the prevention and control of air pollution, deepened urban pollution control, and effectively improved China’s air quality. In 2017, the average concentration of inhalable particulate matter in prefecture-level and above cities decreased by 22.7% compared with 2013; in 2018, the number of excellent air days in Beijing was 227 days, an increase of 51 days compared with 2013.
China’s emphasis on environmental and ecological management has gradually increased, law enforcement efforts and the areas involved have been continuously improved, and the market for the purifiers has fallen. According to the total data released by Avi Cloud (AVC), the air purifier market contracted sharply in 2018, and it fell sharply year-on-year. In 2018, the total retail sales of air purifiers reached 11.67 billion yuan, down 28.0% year-on-year, of which online retail sales accounted for 43.0%. In 2018, the retail volume of air purifiers was 5.291 million units, down 27.0% year-on-year, and online retail sales accounted for 61.2%. Although in the fourth quarter of 2018, due to repeated weather and smog weather, the market has seen a slight rebound, but the overall market decline is difficult to change.
According to the total data released by Avi Cloud (AVC), the size of the purifier under the first quarter of 2019 was 1.19 billion yuan, down 29.8% year-on-year. From the perspective of market growth, the signs of recovery in the offline market are not obvious, and the purifier is still in Low adjustment period. However, from the current situation of the main sales models of the industry, the proportion of high-end purifiers has gradually increased, while the proportion of sales of high-efficiency formaldehyde-removing products has increased. The online market size of the purifier was 1.15 billion yuan, a year-on-year growth rate of -8.2%. The online industry’s decline further slowed down. In March, the market was affected by industry promotion, and the year-on-year growth was slightly increased. From the point of view of the sales structure, the current downward adjustment of the average price of purifiers has been relatively small. At present, some high-end formaldehyde-removing products are gradually on the list.
According to statistics, in 2013, the volume and sales of air purifiers increased by 130.6% and 162.7%. In 2014, the market scale expanded, purchasing power gradually stabilized, and retail sales and sales increased by 35.7% and 31.7%.
The analysis of professionals is mainly due to the further deepening of the national ecological environment strategy. The guiding ideology is to focus on the Beijing-Tianjin-Wing and surrounding areas, the Yangtze River Delta region, and the Yan Plains, and continue to carry out air pollution prevention and control actions, and resolutely win the blue sky defense battle. To achieve environmental benefits, economic benefits and social benefits.
In fact, the development trend of the air purifier market has been declining since 2015. Taking Beijing as an example, according to Zhongyikang’s offline monitoring data, the retail volume and retail sales of the air purifier market in Beijing showed a downward trend in 2015-2018. In 2015, Beijing’s air purifier market accounted for 21.9% of retail sales, with retail sales accounting for 24.7%; in 2016, it fell to 17.2% and 20.4% respectively, and the decline in 2017 continued.
As early as in the “haze and smog” period, companies that saw the momentum of “smog economy” have entered the air purifier market, resulting in a mixed market of air purifiers, and the market is full of counterfeit and shoddy products.
Nowadays, the chaos of the air purifier market still exists. In the results of many random inspections by the relevant quality inspection departments, the unqualified products include not only unknown brands but also the names of well-known brands at home and abroad.
For example, a foreign brand frequently stepped on thunder in the quality inspection of relevant departments. After investigation, it was found that the main body of its air purifier products was more complicated. People in the home appliance industry commented that the foundry production model with multiple production entities can help companies reduce production costs and move forward and backward. However, this model also allows the company to hang a sword of Damocles. “There are hidden dangers such as difficulty in controlling product quality and difficulty in management.”
Well-known brands are not trustworthy, consumers’ confidence in the air purifier market has declined, and on the other hand, the improvement in air quality is the main reason for the decline in the net market.
In the past two years, the number of air purifier manufacturers has gradually decreased. According to public data, in 2016, there were 699 online air purifier brands and 117 offline brands. As of October 2018, the number of online brands decreased to 427, and the number of offline brands decreased to 103. A total of 286 companies were reduced, and at least 35% of the brands have withdrawn from the competition in the air purifier market. According to statistics from Avi Cloud (AVC), the number of total brands in 2018 has dropped from 263 to 114, of which 261 are online and 110 are entered. 46 are offline and 23 are entered. It is mainly divided into three situations: de-stocking companies, barely maintaining enterprises and seeking transformational enterprises. Brands with poor strength were washed out in large numbers.
In terms of average price, the average price of the online market fell sharply, while the average price of the offline market fluctuated less. According to analysis, the signs of recovery in the offline market are not obvious, and the space for the average price of online products has been very limited.
The air purifier market urgently needs to get rid of the current dilemma. Experts assert that the future of air purifiers is definitely the standard for every family. The current dilemma in the air purifier market is only temporary, and this market still has great potential to be tapped.
When air purifier products are linked to smog, the nature of consumer purchases is mostly panic buying, so that enterprises will fall into the dilemma of eating by the sky. However, if we expand the market segment and create diversified functions, it is expected that the net enterprise will get rid of the path of relying on the heavens.
It is observed that there is still much room for improvement between the purifiers on the market and consumer demand. From the survey data of consumers, consumers have a strong demand for environmental monitoring. In addition to PM2.5, sterilization, and formaldehyde removal, it is still a consumer’s concern. At present, the purifier has become a standard in addition to PM2.5. However, in addition to formaldehyde, sterilization and other capabilities need to be improved.
On the other hand, we must continue to strengthen the intensity of sampling and exposure issues. Obviously, the industry chaos continues, not a year or two can be eliminated, it takes quite a while to go to the essence of the purification industry. Industry professionals pointed out that the air purifier industry is still in the adjustment period in 2019, and the industry will continue to shuffle. It is expected that the decline in the purifier market will continue to narrow in 2019, and the structural adjustment of the purifier market will continue throughout the year.
Pursuing high-quality focused products, positioning a good brand image, and making air purifier products fine and fine, then the development of China’s air purifier market will also be freed from a single saturated model and gradually transformed into a mature multi-element. In order to achieve the industry’s “returning temperature”.

The air purifier enters the slow lane and the brand trend is different.
The air purifier market has been receiving much attention from consumers in recent years because he is closely related to the healthy life of consumers and is also a symbolic product of the upgrading of the quality of life. After several years of the rapid development of the air purifier, the market entered a turning point, the growth rate slowed down, the competition intensified, the selling point reversed, and the benign development. In the development period of these years, the gap between domestic brands and foreign brands has gradually narrowed, and the influence of domestic brands has gradually increased, mainly in the following aspects:
The domestic brand share has increased year by year, robbing the foreign brand market According to the offline monitoring data of Avi Cloud (AVC), the share of retail sales of domestic brands in January 2018 accounted for 39.9%, and it showed an increasing trend year by year. In recent years, domestic brands have gradually focused on their brand image and brand influence, and actively developed technology, products gradually cater to consumer demand.
Source: Avi Cloud (AVC) offline monitoring data
The domestic brand price index is gradually approaching foreign brands The price index of foreign brands in the air purifier industry is higher than that of domestic brands, but according to the monitoring data of Avi Cloud (AVC), the gap is gradually narrowing. The price index of domestic brands in 2014 is 0.88, the price index in 2017 is 0.91, and the price in January 2018. The index is 0.93, the foreign brand price index is 1.03 in 2014, 1.06 in 2017, and 1.05 on January 2018. With the improvement of consumption level in recent years, the consumption upgrade is obvious, and the domestic brand products are gradually catching up in both technical and appearance. Foreign brands are gradually gaining favor from consumers.
Source: Avi Cloud (AVC) offline monitoring data, price index = average price of the brand within the week (outside) / the overall industry average price of the week
Foreign brands are difficult to localize, and the unqualified rate of random inspection is 38.4%. From April to October 2017, the General Administration of Quality Supervision, Inspection and Quarantine organized the national entry-exit inspection and quarantine institutions to conduct supervision and spot checks on imported goods other than the statutory inspection commodity catalog. According to the statistics of the General Administration of Quality Supervision, the total number of imported goods outside the catalog was 5,328 batches, and 1,501 batches were found to be unqualified. The unqualified detection rate was 28.2%. Among them, 73 batches of imported air purifiers were randomly selected in the country, and 28 batches were found to be unqualified. The unqualified detection rate reached 38.4%. Among them, the United States, Japan, and South Korea are the most dominant brands, accounting for 25%, 17.8%, and 17.8%, respectively. The main unqualified items are signs and instructions, grounding measures, input power, and current, abnormal operation, components, etc. It does not meet the standards of “Safety of GB 4706.45-2008 Household and Similar Electrical Appliances and GB/T 18801-2015 Air Purifier” in “Safety of Household and Similar Parts of GB 4706.1-2005”.
China’s empty-net market, in the face of such a strong rise of domestic brands, how should foreign brands respond? How to better adapt to the Chinese market? We will wait and see. In fact, whether it is a domestic brand or a foreign brand, it is necessary to meet consumer demand, benign development, and adapt to the changing market.

The air purifier has greatly promoted growth in the middle of the year.
“Poverty is thinking”, in the home appliance industry, the category of air purifiers needs to be like this. In the past year, the air purifier market has been “difficult”: Aowei cloud network data shows that the net market size in 2018 was 11.67 billion yuan, down 28.0% year-on-year, and online retail sales fell 25.7% year-on-year. The year-on-year decline was 33.4%. In this context, the air purifier brand has made two choices to stimulate user demand: one is to complement the function, and the other is to conduct more targeted market education. Judging from the results of the 618 promotion, the practice is more effective. The online monitoring data of Aowei Cloud Network shows that during the 618 periods of 2019, the market value of purifiers was 540 million yuan, a year-on-year increase of 48.6%, and the sales volume was 329,000 units, an increase of 55.7%. Since the fall of the industry in 2017, the net has a good performance in the middle of this year, or related to the following: Market pattern change After 2018, the demand has declined, the price war has become fierce, some small and medium-sized brands have withdrawn from the market, and the repeated quality problems have caused market share to concentrate on the head brands. This Matthew effect will be further released, making it possible for the head brand to launch better products. Market education guidance As the brand shifts its focus to “except for cockroaches”, consumers are also turning their attention from removing mites to removing formaldehyde. Nail Technology found that searching for air purifiers on e-commerce websites, followed by the words “except formaldehyde” appearing in the search bar; in addition, it can also be seen that products with higher overall ordering, many products are emphasized in the description. In addition to the formaldehyde function. In addition to this, the brand is also free to try and other methods, so that consumers have an understanding of the functions of the air purifier in addition to sputum. However, we must also see that in addition to formaldehyde is only a point of the capacity of the air purifier, the future industry wants to continue to develop, but also to continue to meet the changing needs of users. In Nail Technology’s view, eliminating “allergens” or a viable direction, of course, technology should be implemented, not a concept of hype.

Air quality determines the quality of life, the car air purifier should be selected?
According to the latest yellow warning issued by the Central Meteorological Observatory, since mid-Shenzhen, there have been moderate sputum in central and southern Beijing, western Tianjin, central and southern Hebei, most of Henan, north of Shandong, and central and southern Jiangsu. Among them, southern Beijing and Hebei There is severe sputum in the central and northern parts of Henan. From the 10th, the weather in the above areas will gradually weaken or dissipate from north to south.
The haze is annoying and frightening. After all, the fog seems to be mild, but in fact, it contains more than 20 kinds of fine particles and toxic substances harmful to the human body.
For a friend who hates smog, it is safer to wear such a child.
In order to prevent smog from being invaded, citizens often choose to stay indoors, and some people may stay in the car. Then, how to prevent being attacked by harmful gases when exercising in the car?
People often say that air quality determines the quality of life, but everyone has been not too concerned about it. In the face of today’s harsh haze, more and more people are choosing this artifact – the air purifier.
However, in the face of many car air purifier brands on the market, how to choose is also plagued by many riders, the following masters will give you some advice.
1 It is necessary to consider whether it is convenient and safe to place in the car.
Convenience and safety are the primary considerations. If it is not convenient to place it in the car or there is a safety hazard after placement, no matter how good the air purifier can be selected. This requires attention to the following aspects: 1 Appearance volume. When purchasing, it is important to choose a machine that can be placed in the car and not easily moved by car. 2 Manufacturing materials. In general, wear-resistant and high-temperature resistant materials are better than fragile materials.
2 Consider whether the air purification in the car is comprehensive and efficient.
Convenience and safety are the most basic considerations, and purification is a key determinant. This requires attention to the following aspects: 1 Purification method. Air purifiers are generally classified into “filter” purification and “ion cluster” purification. 2 Wind tunnel design. Because there are many “barriers” in the car, if you want to thoroughly purify the air in every part of the car, you need a scientific air duct design.
3 It is important to note that the choice of appearance should be coordinated with interior decoration and design.
In addition, if the shape of the car air purifier is more artistic, you will also have a good mood all the way to drive, and friends and relatives who see the same air purifier can still be forced to install.
4 Care should be taken: the car air purifier is relatively simple, and the filter or ion generator can be replaced on time according to the product manual.

Health care effects of negative oxygen ions: Medical research shows that it is ecological negative ions that have a health care effect on the human body. Because only ecological negative ions can easily penetrate the blood-brain barrier of the human body and exert its biological effects. The reason why air negative ions in nature have created many longevity villages is because of the high proportion of negative oxygen ions, high activity, and long migration distance, thus forming an anion bath environment over the longevity area. Among the many elderly people in Changshou Village, such as Bama, Guangxi, there are basically no common diseases such as cancer, heart disease, and high blood pressure. Scientific research has found that in addition to good living habits and optimistic attitudes, one of the important reasons is that the negative ion content in the local air is high, and an average of 20,000 to 30,000 cubic centimeters of negative ion environment can provide health care for the human body. Effect.
A natural or artificial method of treating and preventing disease with air negative ions called air anion therapy, also known as negative oxygen ionized air therapy. At present, in air therapy, air negative ions are not only used as a treatment method but also widely used as a health care means. Air negative ion medical principle: Cytopathic is the source of all diseases. The key to cell health is the dynamic balance of positive and negative ions. Once the balance is broken, the cells will develop lesions and the disease will occur. Positive ions make the cell membrane hard and thick so that nutrients can not enter the cell for metabolic conversion energy, such as sugar can not enter the cell, stay in the blood becomes diabetes; and waste generated by intracellular metabolism can not be discharged, leading to cytopathic.
The role of negative oxygen ions is just the opposite, which can increase the permeability of cell membranes, allowing nutrients, water, etc. to smoothly enter the cells for metabolism and convert them into energy for human use. For example, sugar in the blood can enter the cell metabolism, and the blood sugar level will drop. Therefore, air negative ions are essential for maintaining cell health. By giving the living body energy to the natural world, factors such as acidity, oxidation, active oxygen, and lactic acid that destroy human health can be gradually reduced, creating a good environment inside the living body, activating the metabolism of the cells, creating a healthy body, and enhancing the living body. Natural healing ability to overcome the disease. Modern medical research has shown that only high-activity small-size negative ions-dynamic negative oxygen ions can easily penetrate the blood-brain barrier of the human body and exert the health care effect of negative ions on the human body. ★ Improve the function of natural killer NK cells against the activity of cancer cells, and inhibit the formation and mutation of cancer cells; ★ inhibit the production of serum cholesterol, purify the blood, activate macrophages, and prevent lipid deposition on the blood vessel wall; ★ Suppresses the formation of leukotrienes, making the body less susceptible to allergies or inflammation; ★ inhibit the production of adrenaline, dilate peripheral blood vessels, improve blood circulation, and maintain blood pressure stability; ★ Prevent the primary cause of arteriosclerosis or liver dysfunction – the production of lipid peroxide. Negative oxygen ion therapy is mainly suitable for: Respiratory diseases: bronchitis, bronchial asthma, allergic atrophic rhinitis, pharyngitis, etc.; Cardiovascular disease: hypertension, angina pectoris, early arteriosclerosis; Gastrointestinal diseases: stomach and duodenal ulcer, chronic gastritis, aphthous stomatitis, spastic constipation; Metabolic and endocrine diseases: diabetes, menopausal syndrome, menstrual disorders, dysmenorrhea, etc.; Skin diseases: urticaria, various types of pruritus, neurodermatitis, chronic eczema, etc.; Others: burns, long-lasting wounds or chronic ulcers, anemia, leukopenia, etc. In addition, according to recent research at home and abroad, air negative ions have an inhibitory effect on the growth of transplanted tumors. Air negative ions have also undergone numerous clinical tests in the medical field, and have been recognized by medical experts. Their health care and many clinical cases have been published in many national key books and magazines.

1. If you are healthy We don’t know what effect the long-term pollutants in the air have. Like cigarettes, lead and arsenic, government regulators have slowly recognized the wide-ranging effects of chemicals in the air. In fact, only a quarter of the 82,000 chemicals used in the United States have been tested for human effects. Therefore, current air purifiers are as important to a healthy lifestyle as healthy eating and clean water.
2. If you live at home, apartment, caravan or any enclosed space We use walls to protect us from chemicals, gases, odors, and particles in the air. However, EPA has found that the air in our residence maybe 2 to 5 times or even 100 times more polluted than outdoors.
3. If you have a new baby or are pregnant, early prevention of chemical exposure is critical. Many researchers now believe that disease is a process of continuous fermentation in the body, which may take several years to evolve from the earliest stages. Therefore, if the fetus or newborn is exposed to an environment with carcinogenic toxins, it can easily cause the disease in later life. 4. If you have children, children’s bodies are developing, adults’ resistance is different, their metabolism is immature, they can’t excrete chemically harmful substances as efficiently as adults, and they are more susceptible to air pollution. Many young children also suffer from allergies and asthma, and particulates and harmful chemicals in the atmosphere can trigger and exacerbate allergies and asthma. 5. If you are over 60 years old, we must face the display, our body is no longer as strong as when we were young. Breathing a steady stream of clean air at this time is like eating a balanced diet that helps maintain a healthy, active lifestyle and promote longevity.
6. If you love modern, convenient lifestyles Ironically, many of the products we create make our lives easier, but they can slowly erode our health. Dry cleaning, dyed plastics, flame retardants, non-stick pans, wear-resistant fabrics, pesticides, chemical cleaning products, personal hygiene products, household appliances, etc. bring harmful gases and toxic dust into our homes. Therefore, your TV and sofa are not important, the important thing is that you need to buy an air purifier.
7. If you have allergies Airborne particles such as dust, pollen, dander, chemical gases released from the floor and furniture can cause allergies. Only activated carbon, HEPA filtered air purifier can remove 99.97% of harmful chemicals in the air particles and air.
8. If you have asthma or other respiratory problems Because your respiratory system has been damaged, the air purifier is a must-have tool in any treatment plan. The air purifier’s HEPA filter captures 99.97% of all allergens, while the thickened activated carbon filter removes airborne chemicals, gases, and odors that trigger or exacerbate asthma. 9. If you live near a major traffic road or industrial facility, busy traffic and fine particles discharged from the factory will penetrate deep into the body and cause danger. Studies have shown that short-term exposure to this polluted air increases the risk of cardiovascular disease and mortality. Long-term exposure actually reduces the overall life expectancy by 1.8 to 3.1 years.
10. If you live in a forest fire zone or near a volcano, both forest fires and active volcanoes (like Hawaii) can cause serious air quality problems, including fine particles, chemicals, gases, and odors. With only activated carbon, HEPA-filtered air purifiers protect us from these specific air pollutants.
11. If you are an imperfect butler, dust is one of the chemicals in the air that we can see with the naked eye. Air purifiers help prevent the accumulation of dust, as well as mold spores, bacteria, viruses, and even pet smells in the air.
12. If you are a diligent butler, even indoor air quality in many clean homes is poor. Today we find that most of the materials and products in our family are releasing harmful chemical gases that cannot be removed or removed by air fresheners.
13. If you have a garden with lawns or trees, coverings, trees, and lawns are sources of mold spores. Spores in these airs can easily enter your home, causing allergic reactions and aggravating asthma.
14. Your immune system is weakened when the immune system is weakened, it may not be able to effectively eliminate toxic pollutants in the body. People with impaired immune systems are at greater risk of serious complications from infection and viruses.
15. If you suffer from MCS AllerAir has a special model to deal with a variety of chemical allergies, and in many cases, other brands of air purifiers can not do, we can do it. The special models we produce are powerful and the only brands that offer functional customization, such as organic cotton pre-filters, burn-proof motors, and powder coated cans. No other company has done its roots in MCS like Allerair!
16. If you or your family members are exposed to second-hand smoke In addition to irritating odors, cigarette smoke contains more than 4,000 chemicals, at least 11 of which are known carcinogens. Only activated carbon air purifiers can effectively capture these complex chemicals and odors.
17. If you have pets in your home Air purifiers can not only remove the pet’s hair, dander, and smell in the air but also help protect your pet from indoor air pollution. Like children, our pets are naturally more susceptible to indoor air differences. They tend to stay indoors for long periods of time and also come into contact with dust, toxins, and chemicals in the air. 18. If you have a flood in your house, the room is very humid and the walls have unsightly water and moldy spots. Many people don’t know that mold can release particles and chemical mycotoxins into the air, causing severe allergic reactions.
19. If you have just moved into a newly renovated house, the various building materials and furniture in the newly renovated room will release harmful gases, which cannot be completely eliminated in a short time and require a long release time. In some old buildings, natural ventilation is better, and new houses are not well ventilated, pollutants are released for a longer period of time, and indoor pollution is more serious.
20. If you plan to refurbish indoor environmental pollution caused by these harmful substances in the decoration, such as paint, new carpet, floor, wall material, wood products, glue and varnish, these will release harmful gases, which will seriously affect your health.
21. If you use art materials, whether you are a child who studies painting or a professional painter, anyone who uses the most advanced art materials will inevitably release toxins and suspected carcinogens into the air.
22. If your home has an odor and fume smell is a common problem in the apartment building, you can’t help your neighbors. Only the air purifier can provide you with fresh and clean air so that you can stay away from second-hand smoke and various odors.
23. If you have a home office Many people don’t know that computers, printers, and fax machines emit low levels of gas chemicals, but they are easily inhaled.
24. If your living space is located near a company In many urban areas, even the best living space is sometimes located near the company. This can cause odors, chemicals, gases, and particles that affect air quality.
25. If you live in rural areas, harmful gases emitted by pesticides and fertilizers can cause serious health problems, including infertility, Parkinson’s disease, birth defects, premature birth, and asthma.
26. If you have an attached garage, the attached garage is one of the main contributors to poor indoor air quality. From cars, other fuel-burning engines, storage paints, solvents, fertilizers and pesticides, you can infiltrate various carcinogens into your home from an attached garage.
27. If you have flu-like symptoms, fatigue or eye irritation, particles, chemicals, gases and odors in the air may cause or exacerbate this symptom.
28. If you have a fireplace or woodstove, the smoke generated when the wood burns seriously affect the indoor air quality. Even when the smoke is relatively low, it can cause difficulty breathing and other health problems.
29. If you are an athlete, you know that your body needs the best nutrition, training, and exercise. An air purifier protects your body and lungs from indoor air pollutants.
30. If you have certain dysfunctions, poor indoor air quality can affect your nervous system and blood circulation, and a good indoor environment can keep you healthy.
