Use habits to determine the effect of the air purifier

Use habits to determine the effect of the air purifier

With the continuous deterioration of domestic air quality, air purifiers are increasingly becoming inseparable products in people’s daily lives. However, while people are keen to buy and use purifiers, the variety of purifier products on the market has claimed to be effective.
At present, various agencies and media in society have different evaluations of purifiers. Some have proposed that purifiers of less than 2,000 yuan have basically no effect, and some have proposed that the effect of purifiers of 600 yuan may exceed thousands of dollars. Recently, some people even proposed self-made. The purifiers are better than the purifiers that sell at a high price in the mall. For a time, people who are planning to buy purifiers are at a loss.
In fact, people often ask, “Which kind of purifier is good,” I am afraid there is no answer at the moment. Just as the cause of air pollution is quite complicated, it is almost impossible to restore the air through a piece of equipment.
The indoor air is very complicated. The purifier is not versatile.
Many consumers are concerned about whether the product can remove PM2.5 when purchasing an air purifier, but the indoor air composition is very complicated. Zhang Pengyi, a professor of environmental science at Tsinghua University, said in an interview with the media that in large rooms, especially large living rooms, in addition to commonly known solid particles such as PM2.5, volatile organic pollutants such as formaldehyde, benzene, and bacteria are also included. The virus and the oil smoke pollution we can’t think of, so simply filtering PM2.5 may not be able to say that the air in the home is very healthy. If you have just renovated your home or added new furniture for a few years, you may want to consider whether you need to remove formaldehyde when purchasing a purifier. If you often cook at home and the fumes are large, the purifier may also have to consider the problem of removing the fumes. Since people often use the purifier to close the doors and windows, this actually blocks the outward diffusion of other indoor polluting gases, so the more you use the purifier, the more attention should be paid to other pollution.
The national standard of the product only determines the “bottom line” of the purifier.
In September 2015, China announced the new national standard for air purifiers. Compared with the 2008 version of the standard, the newly revised national standard for air purifiers clearly emphasizes the clean air volume (CADR) and cumulative purification (CCM) indicators. The amount of clean air is the CADR value, which is used to measure the purifying capacity of the air purifier. The cumulative purifying amount refers to the total amount of pollutants removed during the working process of the air purifier, and the amount of clean air is reduced to half of the initial value. The life angle measures the performance of the air purifier.
It is understood that because different purifiers work differently, some filter the particulate matter through air filtration, and some absorb impurities by ionization adsorption. However, due to the complex causes of haze and the complex composition of indoor air, which method is used? It’s not healthy to say it. Therefore, the national standard of the purifier is only measured for certain aspects of the purifier and should be regarded as the bottom line of the purifier product.
It should be noted that people have different habits of purifiers, some are open 24 hours a day, some are used at some time, and some are opened when the air is not good. In fact, different ways of using also determine the different use effects, and even the difference in the effect of different ways of use may exceed the difference caused by different product purification principles.
Purification ability is also related to the way of use
Many people pay the most attention to the purification ability when purchasing a purifier. In fact, some non-core indicators of the purifier also determine the final use effect. For example, the noise during use is often an indicator that people don’t pay much attention to, but it actually determines whether the purifier can be used during sleep. Generally speaking, the “demand” for air quality during sleep is the biggest. It should be the most useful when the purifier is used. However, many purifiers are currently used with a loud noise, especially when the air volume is high. Many families are When sleeping, the purifier is often adjusted to “middle block” or “low block”. But in fact, the air volume of the purifier determines its ability to change the air, that is, whether it can effectively purify the air in the entire room. If the whole house cycle cannot be achieved, the air purification effect is greatly reduced.
In addition, the size of the air purifier is suitable for its own living room, and the placement of the purifier largely determines the purification effect. The purifier works by allowing the air in the entire living room to flow and ensuring that the air in each corner can pass through the purifier. Therefore, the placement of most purifiers is exquisite. The room where the family activities are more frequent during the day has a living room, a study room, etc., so it is recommended to place the top-rated HEPA air purifier in these rooms during the day to protect the family. In the evening, the family will spend the night in the bedroom. At this time, we recommend placing the air purifier in the bedroom to protect the family from harmful gases at night.

Home and office health artifacts: functional water machine, air purifier

Posted on by

Home and office health artifacts: functional water machine, air purifier

People want health is systematic engineering, in which “environment” and “habit” are the big source of disease. The air we breathe and the water we drink are the most important factors. They are both environmental factors and habitual factors (environment and habits, and other aspects such as soil, emotions, etc.). From the air and drinking water, we start from the source. It is inevitable to work hard without changing from the source because the temporary treatment of health care is not able to compete with the environment and habits.
Modern research on the harm of air pollution and water pollution to health does not need much to say here. It is only mentioned that water pollution may mainly lead to diseases such as stones, cancer, heavy metal poisoning, cardiovascular and cerebrovascular diseases, digestive diseases, etc. Air pollution is easy. Lead to lung cancer, leukemia, chronic obstructive pulmonary disease, asthma, rhinitis, skin diseases, and other diseases. It is emphasized here that Chinese medicine is also unparalleled in its emphasis on air and water. Research on air and water is rich in content. For example, air, the corresponding nouns in ancient Chinese medicine are the heavens, the weather, the essence, the anger, the Tianyang and so on. “The Yellow Emperor’s Internal Classic” discusses what is “real person”, “there are people in the ancient times, who raise the world, grasp the yin and yang, breathe the essence, keep the gods alone, and if the muscles are one, they can hide the heavens and the earth, and there is no end to it.” If the air is polluted, how can it be “breathing” and how can it be made into “real people”? He also said that “the weather, the clean and bright people, the Tibetans are not limited, so they don’t go down,” “the heavens are qi, the clean is the ambition,” Imagine if the air is polluted, it is not called clean, and you can “Joshi” (Mental state is very good)? Conversely, air pollution is one of the causes of upset and even mental illness. In the Qing Dynasty, Tang Rongchuan said, “The air of the human body is born in the umbilical dantian, the sea of ​​air, the umbilical lower, the kidney and the bladder, and the place where the water is homed. This water is not self-contained, and it is absorbed by the nose. Yang, from the lung tube to the heart fire, under the umbilical, steaming its water to become gas”, it seems that breathing good air has a vital role in normal physiological activities. So there is no good airline? ! In terms of water, for example, Zhang Zi and Zuo Zhi in the Confucianism of the Confucianism are an important article in the theory of Chinese medicine.
The use of advanced water purifiers and air purifiers can directly improve the body. Hangzhou New Youth Hertz Super Energy Instrument (functional water machine) I have used it for more than 3 months, and all aspects have been improved obviously. Many people have witnessed it. Another example is the Shan Yimei brand air purifier. I have personally experienced the blood test comparison experiment, that is, before and after using the air purifier (in the room where the air purifier works) (30 minutes – 60 minutes indefinite), use ” A drop of blood instrumentation can see the quality of the blood (such as the number of red blood cells in the same field of view, blood viscosity, blood cell viability) has been significantly improved. And it is true that in such a room, the mind is fresh, responsive, and unconscious. The changes in blood status are shown in the figure.
This makes the author very shocked, because we do health care, regardless of technology, or products, and ultimately we must improve the quality of blood, and this air purifier is easy to do, and we work hard to do physical therapy, not necessarily It is possible to achieve such an obvious effect, which can be said to regulate the body and improve health only between breathing. This also caused the author to reflect, our treatment and conditioning methods can not fall too far into the box, the role of the best air purifiers is also a way to treat conditioning, and deep medical treatment; Western medicine ventilator, all kinds of qigong, breathing exercises Law, drug fumigation, are worth pondering. As far as water is concerned, “spa” is also completely identifiable and very valuable.

New air pollution killer PM0.3

Posted on by

New air pollution killer PM0.3

The smog weather in a field made consumers realize the harm of PM2.5. In fact, PM2.5 is only a van concept. PM2.5 in the consumer’s mouth, 95% of which is PM0.3, one is more than PM2. .5 small and nearly 600 times the “killer” can enter the lung particles!
Therefore, to be precise, PM2.5 can be subdivided into PM0.3 (below 0.3 microns) and narrowly defined PM2.5 (0.3 to 2.5 microns).
I believe that many consumers are familiar with PM2.5, but since China has not carried out PM0.3 monitoring on a large scale, many consumers still have a blank concept of PM0.3, which has led to many air purification products on the market. Remove the effect of PM0.3.
PM2.5, also known as fine particulate matter, refers to particulate matter with an aerodynamic equivalent diameter of 2.5 microns or less in ambient air. The higher the concentration in the air, the more serious the air pollution. How serious is its health and impact on human health? I believe many people have already experienced it personally. What is the focus on PM0.3?
What is PM0.3
PM0.3 is a general term for solid particles or droplets with a diameter of less than or equal to 0.3 microns. It is also known as a particulate matter that can be incorporated into the lungs. The particle size is smaller, only 1/200 of the hair. It is rich in toxic and harmful substances and has a long residence time in the atmosphere. PM0.3 can drift over 1000 km, which has a greater impact on human health and the quality of the atmospheric environment.
PM0.3 is not perforated?
Compared with PM2.5, which can only enter the lungs by breathing and block the alveoli, PM0.3 can be described as “pervasive” in the propagation channel. Because the particle size is only 1/200 of the hair silk, PM0.3 can not only reach the deepest part of the lungs through breathing, but also can swing into the alveoli and enter the blood tissue of the human body, and can not be removed permanently. Damage and prevention are far more difficult. We know PM2.5.
Due to the wide range of sources of PM0.3, people can hardly avoid contact with them in daily life. Studies have shown that more than 90% of PM0.3 comes from waste gas from power plants, factories and automobiles, and contains heavy metals such as mercury, cadmium, and lead. And stay longer in the air.
Indoors, PM0.3 mainly comes from decoration, home paints, and adhesives. After the PM0.3 in the air enters the human blood circulation, it will cause health hazards to many human organs such as cardiovascular and brain. Heavy metal PM0.3 will also damage the human respiratory system, immune system, and circulatory system. PM0.3 containing formaldehyde, benzene, and other substances is the root cause of leukemia, nasal cancer, and colon cancer.
PM0.3 is the most penetrating
For indoor air treatment, consumers generally accept air purifier products. The purification is mainly through increasing indoor air circulation and filter purification. The most efficient one is the HEPA filter, also called high-efficiency particles. There are four main filtering mechanisms for HEPA filters:
(1) The first type is the interception mechanism, and the removal of large particles is very obvious;
(2) The second mechanism is the influence of gravity. The particles with small volume and high density will reduce the movement speed when passing through the HEPA filter, and naturally settle on the HEPA filter;
(3) The third mechanism is the influence of airflow. Due to the uneven weaving of the HEPA filter, a large number of air vortices are formed, and the effects of the cyclone received by the cyclone are adsorbed on the HEPA to achieve the filtering purpose.
(4) The fourth filtering mechanism is that the ultrafine particles impinge on the HEPA filter fiber under the action of Brownian motion, and are filtered by electrostatic adsorption under the influence of van der Waals force.
Compared with smaller volume particles such as P0.1, PM0.3 is not easily affected by a cyclone or van der Waals force, and the capture mechanism of large particles also has little effect on PM0.3. Therefore, PM0.3 is also the most penetrating. The force particles measure the pros and cons of the HEPA filter, mainly depending on the purification efficiency of PM0.3.
to sum up:
For PM0.3 such fine particles, any mask is difficult to resist, the only way is to reduce pollution, and the purification products that are generally accepted by consumers in the market also take PM2.5 removal rate as one of the standards of cleanliness, but The study of PM0.3 can be said to be a blank.
The PM0.3 particles in the air can be removed from the air mainly through the HEPA filter. However, the industry has not yet made standards for the purification of PM0.3, which has also led to the uneven quality of HEPA filters. When consumers purchase air purifiers, In addition to avoiding the so-called “black technology” of the manufacturer, it is also necessary to pay attention to whether it is equipped with HEPA filter and the removal rate. Of course, the filter should be replaced and cleaned regularly to avoid secondary pollution.

Five factors that determine the purification effect of air purifiers

Posted on by

Five factors that determine the purification effect of air purifiers

For air purifiers, the purification of air is the primary condition for measuring the quality of an air purifier. In addition, it is energy consumption, noise, service life, and other considerations. Then, from the technical materials and conditions of the use of air purifiers, what are the main factors affecting the purification effect of air purifiers?
The first is the filter material of the air purifier. For air purifiers, the purification effect is mainly from the filter material. Generally speaking, air purification filter materials have various limitations, such as non-woven fabrics, filter papers, etc., to ensure good ventilation, but also to effectively filter harmful substances in the air, the two are difficult to balance. Although activated carbon has a strong adsorption capacity, it is easy to saturate. With the results of the pollutants, the purification effect will be significantly reduced. In different indoor environments, the requirements for air purifier filters are different. Therefore, in the process of selecting an air purifier, whether the function of the filter material meets the actual needs, whether it is convenient to replace, the service life, etc., is the first problem to be considered.
Followed by the performance of the air purifier fan. The purification efficiency of the air purifier is closely related to the size of the air volume. Because the purification process of any air purifier requires air to pass through the purification device inside the purifier, and the fan is the energy source of the air circulation. In general, the higher the power of the fan, the higher the purification efficiency and the greater the noise. However, the silence of the air purifier structure is the mainstream method for most powerful air purifier brands to reduce the noise of high-power fans without affecting the purification efficiency.
Again, the object to be purified by the air purifier. In general, air purifiers on the market are targeted. For example, some air purifiers mainly purify and adsorb chemical pollutants, and the effect of purifying formaldehyde pollution on new decoration and new furniture is obvious; some are mainly aimed at efficiently filtering inhalable particles in the air. Of course, there are also air purifiers that are ingenious to kill bacteria, germs, and maintain human health and safety, such as Aegis. When consumers choose an air purifier, they should consider the air pollution of the applied place more and choose the air purifier.
There is also an air purifier workspace volume that is also a part that needs attention. Different air purifiers have different effective workspace volumes due to different fan and performance designs. For example, an air purifier with an air volume of fewer than 120 m3 per hour is used in a room below 20 m2, and the purification effect is most obvious.
Finally, it is necessary to clean the level of pollution in the room. The degree of indoor air pollution is also one of the factors affecting the purification effect of air purifiers. For example, in the environment with a high concentration of chemical pollutants, it is necessary to replace the adsorbent materials more frequently. In the summer when viruses and germs are more likely to breed, it is necessary to pay attention to antibacterial peptide filtration. The sterilization effect of the net.
In general, the filter material and the adsorbent material are determined for the service life and purification effect of the air purifier; the design of the fan and the air duct is determined by determining the energy efficiency of the air purifier; the overall structure safety and noise effect of the air purifier is determined by the outer casing of the air conditioner. And electromechanical; it is the monitoring system and display system that determines the ease and intelligence of the air purifier. Depending on the specific needs of air purification, air purifiers also have a variety of changes in detail, which also gives consumers more and more accurate air purifier products to choose from.

Household air purifier can effectively improve summer “air conditioning disease”

Posted on by

Household air purifier can effectively improve summer “air conditioning disease”

The summer weather is hot, and it is almost necessary to close the window to turn on the air conditioner to cool down. We know that the elderly, pregnant women and infants are relatively weak people. However, indoors are not ventilated for a long time, and the air quality is poor, but people are worried. Whether it is indoors or outdoors, healthy breathing is particularly important.

According to a report on the Internet, according to the research report, the carbon nanoparticles in PM2.5 have obvious damage to the first pregnancy. The smog contains a large number of particulate pollutants such as PM2.5, which can induce various respiratory tracts. Diseases, especially mothers and babies and the elderly, are more vulnerable. Many pregnant women, the elderly, and children breathe fresh air, sunbathe, go out for a walk, and do sports. But sometimes there will be smog days, the outdoor air pollution is serious, but in desperation, I have to go home to “hide” and dare not go out.

The reduction of outdoor sports means an increase in indoor activities. The weather with severe outdoor air pollution leads to a reduction in the number of window ventilation. The exhaust gas generated by indoor activities, the harmful gases emitted by furniture, and the smell of cooking smoke can not be discharged in time. The air does not input in time, the indoor air is not circulating, and the indoor air quality is actually worse. Indoors with severe air pollution are prone to dizziness, vomiting and other symptoms, and may even cause respiratory diseases.

Experiments have shown that for every 1 °C rise in room temperature, formaldehyde volatilized from wooden furniture and flooring will increase the concentration of formaldehyde in the air by 0.15 to 0.37 times. In the high temperature and humidity environment both indoors and outdoors in summer, it will accelerate the release of formaldehyde in furniture and other decoration materials. To this end, experts have called for the rational use of air purifiers with formaldehyde-removing functions during the summer to improve and improve air quality and reduce indoor air pollution.

An indoor household air purifiers can not only remove smog particles such as PM2.5 but also dust and odor, etc.; it can also decompose harmful gases such as formaldehyde and benzene. It is a good choice to provide a healthy breathing environment for your family and to care for your family’s health. Especially in the summer season, the weather is hot, the air conditioner is turned on, the ventilation is less, the air is not circulated, and the exhaust gas in the home cannot be discharged in time. It is especially important to provide a good breathing environment for your family at this time. So how do you choose an indoor air purifier?

Can infants use air purifiers?

Can infants use air purifiers?

 

Infants can use air purifiers, which should be used when the air quality is not good, to reduce indoor air pollution.

The air purifier itself has no negative impact on the health of the baby, but if the air purifier is not used, the baby may be exposed to air pollution, which may have a serious impact on the baby’s health.

A year ago, UNICEF published a report stating that air pollution can affect the brain development of infants and cause brain damage. Air pollution can also cause pneumonia and other diseases in children under one year of age and is one of the causes of infant death.

In the past few decades, Europe and the United States have conducted a number of studies on air pollution and infant health and concluded that air pollution affects infant health. However, the air pollution situation they studied is inconspicuous compared with the air pollution situation in many parts of Asia, including most parts of China. The serious air pollution in Asia has a serious impact on infant health. Further research data is needed.

In recent years, smog in China has been very serious, and its impact on the health of infants is undeniable. In this case, efforts should be made to reduce the impact of air pollution on themselves and their families. The use of air purification equipment is one of the methods. Family, be sure to do a good job of air purification, not to be taken lightly.

air purifier? Don’t buy it for indiscriminately!

Posted on by

air purifier? Don’t buy it for indiscriminately!

A lot of things can be judged by logic, including buying an air purifier and hearing the details. (But I can’t talk about logic in anything. I have been telling the logic to be killed by my wife several times because of all the troubles.)

My first air purifier was bought in 2004. Of course, it must be a Panasonic. What do I mean by that? ——Air purifier is not a smog derivative, not a PM2.5 filter. In 2004, the Chinese did not know what PM2.5 was;
Air purifiers, as the name implies, are machines that purify indoor air, and indoor air pollution sources are far more than PM2.5.
Japan’s PM2.5 has an average annual value of 10, but we are familiar with Panasonic, Daikin, Toshiba, Mitsubishi, and Hitachi to produce air purifiers. One of the standards in Japanese hotels is the air purifier.
So, first of all, we should have a correct understanding of the air purifier.

However, after all, it is China, and China is a smashing China. The harm of PM2.5 does exist in the field. Therefore, there is nothing wrong with the purchase of air purifiers. Focus on PM2.5 only, because even in Beijing, the annual average PM2.5 concentration is around 80, and the air quality is up to 190 days. We can also play the role of air purifier in the absence of smog. The value of this money is spent!

So, how can we buy a cost-effective air purifier?

1, in the choice of brand, try to choose those familiar brands.
There is nothing special about the basic functions of air purifiers, so don’t trust the so-called “professional” brands that don’t know which country to pop up. What is a professional? At best, it’s a special one. It was Matsushita. Matsushita began producing air purifiers in 1962; at that time, the CEO doors of these “professional” brands were not yet born!

[Air Purifier Science Series] Selection and Maintenance of Air Purifiers

Posted on by

[Air Purifier Science Series] Selection and Maintenance of Air Purifiers

Nowadays, the smog, decoration pollution of formaldehyde, bacteria and other hidden invisible killers around us are endangering the health of the family. As one of the most effective products for the current air environment, air purifiers have become the first choice for most families.

But in the face of a large number of products with different shapes and performances on the market, how should we choose? Please take a look at the small series below!

Shopping tips

1. Select the purchase channel

When purchasing an air purifier, it is recommended to purchase it in regular channels such as large shopping malls, electrical stores, brand stores, and mainstream e-commerce websites.

2. Purchase an air purifier according to your actual needs

At present, the air purifier brand, function, performance, design, and price are very different, dazzling. Consumers are advised to purchase products according to their actual needs, not as many features as possible. For example, for consumers who need to protect PM2.5, it is recommended to choose an air purifier with an outstanding PM2.5 purification capability.

However, in the case of an air purifier, the purifying function is the most important function. If your requirements for indoor air purifiers are based solely on improving indoor air quality, you can choose a type that simply purifies the air and is cost-effective.

As people’s needs for quality of life increase, the demand for air purifiers is no longer simply to purify indoor air. For example, those who work in a closed air-conditioned room, because the air conditioning dehumidification makes the air in the room very dry and the skin becomes dry, so when choosing an air purifier, you will choose a skin-friendly function. Humidifying air purifier.

People who have been in a lot of people for a long time and have high indoor pollution need to breathe fresh air without bacteria. When purchasing an air purifier, they will prefer a small air purifier suitable for desktop.

People who drive frequently should choose car air purifiers to purify various car odors and even ease driving fatigue.

3. Is there a scientific purification principle to achieve an efficient air purifier effect?

There are five internationally accepted principles of air purification, physical, electrostatic, chemical, ionic and composite. In general, physical purification is the most common and effective method. For example, dust, pollen, allergens, viruses, and other large particulate matter can be filtered by HEPA technology in physical purification mode; while harmful substances such as benzene, toluene, formaldehyde, and other odors can be adsorbed by activated carbon in physical purification mode. Purification.

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 × 0.12. The ability to purify other contaminants should be combined with the applicable area.

4. Are the energy efficiency ratio, energy efficiency rating and ozone emission reasonable?

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 higher the energy efficiency ratio and energy efficiency rating, the more energy-efficient the air purifier is and the lower the cost of use.

Ozone as a strong oxidant has a certain purification ability, but it is harmful to the human body. The state has mandatory safety requirements for the amount of ozone released from air purifiers, limited to ≤ 5 × 10 – 6% (ozone has a fishy smell).

Maintenance

Like the water purifier, the air purifier needs to be cleaned regularly, and some need to be replaced with filters and filters to maintain its purification effect. The maintenance and maintenance of the air purifier depend on different types of air purifiers.

The primary filter in the air purifier should be cleaned frequently. Generally, it should be cleaned once every half month. When using a vacuum cleaner or a clean brush, when there is more dust on the fan and electrode, it should be removed. Generally, it should be repaired once every six months. The long hair brush can be used to remove dust from each electrode and wind blade. When the air purifier is not in use, it should be cleaned and put into the box and stored in a ventilated and dry place. Attention should be paid to moisture protection to avoid the use of efficiency or damage due to moisture.

Cleaning

1. The front filter (usually the back cover of the chassis) takes a long time to collect some dust, which affects the air intake and affects the air purification effect. Therefore, it is necessary to use a vacuum cleaner to suck the dust away or use a rag to clean it, or even wash it to dry.

2. Filter net, part of the filter net needs to be taken to the sun at the end of the sun, and the purification efficiency can be better maintained, such as activated carbon filter.

3. Deodorizing filter, a deodorizing filter for a few air purifiers, to achieve the technical level of water washing, can be washed by water, that is, to maintain purification efficiency, and extend the cycle of the filter.

4. The ion generator is generally built-in and does not need to be cleaned. The better ionizer has higher working efficiency.

Second, maintenance

1. Rear panel (front filter)

Is the air purifier useful in addition to formaldehyde?

Is the air purifier useful in addition to formaldehyde?

Worried that formaldehyde is not good for health, what kind of formaldehyde removal method do you use? In addition to formaldehyde, after ventilation, green plants, activated carbon, formaldehyde air purifiers have become more family choices. But air purifiers are useful in addition to formaldehyde, and netizens have more than one controversy.

As we all know, the main reason for the indoor formaldehyde exceeding the standard is the interior decoration building materials, so it can be seen that the formaldehyde pollution is eliminated, and the scientific way is to control at its source.

Main decoration materials for indoor decoration materials

(1) Mainly from the board: interior decoration of plywood, medium-density fiberboard, blockboard, particleboard, veneer, reinforcement, and laminate flooring;

(2) artificial panel furniture;

(3) Furniture containing formaldehyde paint;

(4) Wallcovering wallpaper, chemical fiber carpet, foam plastic, paint coating, heat insulation layer, adhesive, and other decorative materials;

Summary: The main source of indoor formaldehyde pollution is urea-formaldehyde resin glue with formaldehyde as the main component in various decoration materials.

Assuming there is formaldehyde pollution in the room, how can we manage it, is it useful to remove formaldehyde in the air purifier?

In a certain temperature and humidity, the formaldehyde in the room is volatilized in the form of free gas, which we call formaldehyde pollution. When the concentration of formaldehyde reaches 0.06-0.07 mg/m per cubic meter of air, children will experience mild asthma, and long-term exposure to formaldehyde is carcinogenic. The indoor formaldehyde pollution hazard incident: “killing formaldehyde”, “a renovation for 2 years to stay in leukemia”, “90% of leukemia from home decoration” has been repeatedly mentioned in the news. If there is an air purifier in the house, you can quickly purify the indoor air to achieve the aldehyde removal effect.

Although air purifiers are useful in addition to formaldehyde, they are not *. When the outdoor air quality is good, it is necessary to ventilate frequently. The green plant, activated carbon in addition to formaldehyde is relatively weak, can be used as an aid. But it is not a substitute for formaldehyde air purifiers and ventilation.

“China Air Purifier Industry White Paper (2019)” released

The “White Paper on China’s Air Purifier Industry (2019)” released in Beijing recently pointed out that in addition to formaldehyde, it is becoming a breakthrough point in the transformation and upgrading of the air-net industry. The report compiled by the big data company Aowei Cloud Network (AVC) and other institutions show that in 2018, China’s air purifier market was 11.67 billion yuan, down 28% year-on-year. The sales penetration rate of high-efficiency formaldehyde removal products (formaldehyde CADR ≥ 200) reached 18.5%.

On May 24th, sponsored by China Household Electrical Appliances Association, Shanghai Environmental Protection Industry Association, Shanghai Environmental Protection Industry Association Air Clean Equipment Committee, Air Purifier (China) Industry Alliance, Beijing Aowei Cloud Network Big Data Technology The “2019 China Air Purifier Industry Summit and China Air Purifier Industry White Paper Conference” hosted by the company was held in Beijing, and the “China Air Purifier Industry White Paper (2019)” was released, aiming to guide the industry to a stable Sustainable development.
The summit focused on the theme of “winning the aldehydes and winning the market and enjoying the rebirth of innovation”, and conducted in-depth exploration and discussion on the performance of the past air purifier market, future technology, and market development trends. Experts at the conference said that the air purifier market is currently at low tide, and the overall industry is suffering from a sharp drop in consumer demand. Enterprises are also actively looking for new demand points, such as formaldehyde-free air purifiers, which are products that consumers really need. It is a product that can adapt to the needs of the market and bring about industry growth. In the future, industry organizations will assist production companies in the development of relevant standards and events, and promote the transformation and development of enterprises. The summit issued a heavyweight “China Air Purifier Industry White Paper (2019)” to guide the industry to stable and sustainable development.
The bad weather conditions of the past few years have made the empty net industry of “depending on the sky” expand rapidly. Since 2018, China’s environmental governance has continued to deepen, weather conditions have improved significantly, consumers’ panic buying behavior has ended, and it has begun to enter the era of rational purchase.
The haze is reduced, and the aldehyde is new. Faced with changes in the situation and demand, air purifiers are actively looking for new demand points. The problem of interior decoration in China has been prominent, and the rate of formaldehyde exceeding the standard is high. Coupled with the impact of unexpected events, consumers “except aldehyde” Consciousness is further awakened. The formaldehyde release cycle is long. Except that formaldehyde is systematic and long-term work, the formaldehyde air purifier is just in line with this characteristic, and it can be used for a long time. As a result, the future of the air purifier is still limitless.
Functional improvement

From January to April 2019, the market size of the air purifier was 2.94 billion yuan, down 21.5% year-on-year, and the market’s downward trend was obvious. In terms of products, in addition to formaldehyde purification and penetration rate continues to rise, but the product price is higher, the technology is mainly adsorption, there is still a large room for development in the future.
At present, the development status of air purifier products: After the introduction of formaldehyde-removing products, enterprises are constantly looking for new consumption pain points and launching more products that meet market needs.
In order to further explore the industry situation, experts at the meeting exchanged views on the status quo and development expectations of the industry. They agreed that although the formaldehyde function is not a new function, the technology has been updated to meet the needs of consumers. With the advancement of technology, the function of formaldehyde removal will be further improved and the effect will be continuously improved.
For the development of air purifiers, experts who participated in the discussion believe that people’s pursuit of healthy quality life has no end, which means that consumers’ demand for air purifier products will continue to increase, and the market prospects are still worth looking forward to.
The newly released “White Paper on China’s Air Purifier Industry (2019)” shows that at present, the air purifier industry is at the stage of bottom-side adjustment. The “White Paper” concluded that after the explosive growth, the brands and products of air purifiers on the market were uneven. After rapid development, there were problems such as single product function, uneven brand, weak after-sales service, and poor product stability. In the future, industry standards will be more standardized, product functions will be more diversified, policy subsidies will be in place, consumer awareness will increase, and the potential of the air purifier industry should not be underestimated.
Lu Jianguo, the deputy chief engineer of the China Household Electrical Appliances Research Institute and director of the Institute of Test and Measurement Technology, explained in detail the standards and industry standards for air purifiers at the summit. Lu Jianguo said that standards can not only regulate the manufacturing behavior and benign competition of enterprises but also play a role in guiding consumers to purchase.
Industry observers pointed out that the decline of the air purifier industry after the outbreak of growth is a pain in development and will not affect the overall industry to move forward steadily. With the development of the social economy and the awareness of residents’ healthy living, the future development of the air purifier industry is huge, and the industry will eventually move toward a benign development path.
