Air purifier conscience guide, so buy, no longer have to worry about being pitted

Under the smog, life is important. The smog of earning money, the smog of the official, the ordinary people, know the smog, anti-smog.

Americans love to sterilize, Japanese people are afraid of pollen, and Chinese hate PM2.5. In the special industry of air purification, we are the only country in the world that is seriously polluted by smog and has the strength and willingness to purchase air purifiers. Hey, so, in the face of thousands of air purifiers on the market, from hundreds of oceans to tens of thousands of oceans, how can you choose not to be deceived?

Then, before entering the topic, the sheep and the old wet first knock on the blackboard, you must know the following points –

We purchase air purifiers, mainly for indoor pollutants. Simply put, indoor air pollutants fall into three categories:
1 Particulate matter | such as inhalable particulate matter (PM10), smaller particles can inhale PM2.5 in the lungs, pollen, pets or body exfoliation;
2 Volatile Organic Compounds (VOC) | including various odors, formaldehyde or toluene pollution caused by decoration;
3 Microorganisms | Mainly viruses and bacteria.

The principle of removing indoor air pollutants
Mechanical + electrostatic + water filter

Mechanical type, that is, “filtration”, high air volume fan + filter screen, can intercept some particles and microorganisms, large particles “adsorbed on the filter screen” and adsorbed, small particles are absorbed by the electrostatic force of gravity of the filter fiber, Therefore, the filter screen is often a layered structure, and one layer cannot be blocked.

The most popular air purifiers on the market, with the most mature technologies and products, are mechanical filter purifiers. Electrostatic and water filtration purifiers, although there is no need to replace the filter, the filtration efficiency is very general, it will bring secondary pollution such as ozone and chlorine, and the problem of microbial growth, so it will not be described.


HEPA high-efficiency filter
(High-Efficiency Particulate Air Filter)
Referred to as HEPA

Various countries have different standards for high-efficiency filters, and European HEPA grades (EN 1822) are often mentioned. In the latest EN 1822:2009 standard, H13 grades or higher can be called HEPA (so strictly used) The H10-H12 purifier can no longer be called HEPA).

From H11 (filtration efficiency >98%) to H13 (filtration efficiency >99.97%), with the same CADR value (described below for CADR), the purifier can be faster with the purifier of the H13 filter. Lower, while the H11 filter takes longer. The higher the level of HEPA, the better. Of course, the higher the level, the more expensive the price.

Some air purifiers add a lower filter front filter to the HEPA to filter out larger particles such as hair, which improves HEPA efficiency and longevity, as well as cost control.

HEPA is the core component of the purifier and needs to be replaced at regular intervals.

Activated carbon or zeolite

Both HEPA and pre-filters filter particulate matter and some microbes, and other important indoor air pollutant, volatile organic compounds (VOCs) such as formaldehyde. Toluene requires an additional filter to remove. The most widely used is the activated carbon filter. Activated carbon absorbs VOC through its huge surface area, removing formaldehyde and various odors. The same is true of the basic principle of zeolites.

About air purifier
The most important CADR and CCM

1 CADR (Clean Air Delivery Rate), the clean air output ratio
CADR is the ratio of the air purifier output clean air obtained by the American Association of Home Appliance Manufacturers (AHAM) according to strict test standards. It is generally expressed by the area ratio time (domestic use m3/h), that is, each How many volumes of air are purified in an hour. The higher the CADR value, the higher the purification efficiency.

Simply put, CADR/10 (poor air quality can be increased to 15) can be used as a reference for purifying the area. For example, the nominal CADR value is 750m3/h purifier, the applicable purification area is about 750/10=75m2, if the purification requirement is higher, it is 750/15=50m2.

International standards require that the purifier must change the air of the area to be used more than 5 times per hour, so each purifier will mark its applicable area, such as 20m2, the height of the floor is 3m, which is 60m3, which requires the purifier. The air volume needs to be above 300m3/h.

2 CCM (Cumulate Clean Mass), cumulative purification
As the name implies, CCM stands for the endurance of the purifier. The new national standard divides the CCM value into 1~4 grades (the higher the number is, the higher the level), corresponding to different pollutants, the particulate matter uses the P1~P4 standard, and the formaldehyde uses the F1~F4 standard.

The CCM value determines that the number of days the screen can be used can be determined under conditions where the purifier, room area, and contaminant concentration are known. However, because the national standard threshold is low, some better purifiers will be marked as “Super P4/F4” or “Several times P4/F4”.

Air purification process

The indoor environment in which we live is always in gas exchange with the outside world. Indoor pollutants, such as formaldehyde that has just been renovated, particulate matter produced by smoking, and odors of other objects, overall, indoor particulate matter or pollutants, have been in a state of dynamic balance.

The function of the air purifier is to control the particulate matter or pollutants in the dynamic equilibrium state to a lower concentration range through the combination of “high air volume + high filtration efficiency”. In order to achieve a better purification effect, it is necessary to check the air leakage in the room. If the air leakage is very serious, even the best purifier, the high CADR, and CCM are also white.
The only solution is the fresh air system. By continuously changing the indoor and outdoor air, the fresh air system always maintains the indoor air pressure higher than the outdoor, thus preventing the outdoor air from directly entering the room. The Yang Lao Wet House installed a fresh air system before the renovation, and it has its own PM2.5 filter core. On the basis of the ordinary fresh air pumping air, the purified air is sent into the room.

From this point of view, the air purifier can only temporarily purify the indoor air, does not have the ventilation function, and the purification area is limited, and most fresh air systems must be installed before the house is renovated, so the air purifier can be said to be unmounted. A compromise between the family of the fresh air system.

Air purifier noise

Noise is an inevitable problem for all filter purifiers. The greater the air volume, the greater the noise. Even if manufacturers use a variety of sound-absorbing or sound-proof methods, once the air purifier is turned on, including the fresh air system, it will still add a sinuous background sound to the home.

The noise of the purifier for a long time to work stably, as well as the serious pollution of the air. The noise during maximum power operation is a factor to be considered when purchasing. Different types of purifier manufacturers will basically indicate the decibel number (dB) during operation. Reference.

Additional features / smart services

In today’s smart age, many home appliances add one or more additional features to the product, such as APP control, smart detection, mute or sleep mode, etc., such as smart detection, you should pay attention to the real-time monitoring of the air quality near the machine. , or the entire room, and whether the air purification effect in silent or sleep mode is guaranteed.

Sheep and old wet to say separately is after-sales, this is a problem to buy any home appliances, of course, it is still related to the manufacturer, it is recommended to choose the mainstream model of the mainstream brand as much as possible, saving the factory because of the niche and abandoned it into three.

Of course, the air inlet and outlet of the purifier, the placement and land occupation, the ease of movement, and the level of the color are all important factors that influence your final decision.

What is the reason for buying an air purifier?

What is the reason for buying an air purifier?

Is the air pollution in the living city serious? Maybe some people are in a region where air pollution is not so severe, and the vigilance and harmful feelings about air pollution are not so strong, but in fact, air pollution is ubiquitous, and China’s reform is nearly four. Ten years later, China’s economic development has undergone earth-shaking changes, but at the same time it has inevitably brought about environmental pollution, including air pollution, water pollution, and living pollution. In the current, polluted environment, the use of air purifiers is imminent, not only outdoor air pollution, indoor air pollution is even more important to people. So what is the reason for using an air purifier?

First, the decoration room in addition to formaldehyde

If smog is still bullied by seasons, formaldehyde is relatively fair. Rural cities are treated equally, and winter and summer are not divided. As long as you decorate the house, formaldehyde must follow suit. In this year, who did not have one or two newly renovated houses?

The harm of formaldehyde, every enterprise that makes air purifiers are backward, but on the thorough purification, not every company understands.

Friends who have studied the air purifier know that most of the filter elements for purifying formaldehyde on the market are activated by activated carbon. This method is really effective, especially in the initial stages of purification. However, with the passage of time, the adsorption of activated carbon is gradually saturated, and the continued removal of formaldehyde appears to be incapable, and even if the temperature is high, the adsorbed formaldehyde is re-released, causing secondary pollution. The best way to not be hurt by the enemy is not to shut it up, but to be completely humane. The same is true for the elimination of secondary pollution of formaldehyde.

At present, there are few purifiers capable of implementing “humane extinction” of formaldehyde in the country. The cold catalytic agent of the Oulongdes air purifier decomposes formaldehyde technology and rapidly decomposes formaldehyde into carbon dioxide and water which are harmless to the human body under normal temperature and pressure. No secondary pollution.

Second, the outdoor atmospheric environment

As early as 2008, China’s Ministry of Environmental Protection announced that in the 519 cities in China that reported air quality data, only 21 cities reached the first level, accounting for only 4% of the total.

Third, to ensure healthy breathing

Two-thirds of a person’s life is spent indoors, and according to the survey, the indoor air pollution rate is 5-10 times that of outdoor, chemical pollutants such as second-hand smoke, formaldehyde, and helium contained in the room. , benzene series, ozone, and odor, indoor sanitary products may produce carbon dioxide, carbon tetrachloride, diphenyl, toluene, xylene, and other toxic substances, which are very important to the human body. Long-term exposure to indoor air pollution can easily lead to various diseases such as respiratory diseases, lung cancer, and atherosclerosis.

The above three reasons tell you that it is not acceptable to not use an air purifier. The multi-layer filtration system of the air purifier can filter, adsorb and decompose the indoor air pollutant layer to achieve cleanliness of more than 99.97%.

Fresh air system and air purifier, how will you choose?

Fresh air system and air purifier, how will you choose?

Faced with a high incidence of winter smog and more and more serious decoration pollution, people are becoming more and more aware of health. How to improve the internal environment of their own living without changing the external environment has become the focus of attention. At present, air purifiers and fresh air systems are common in the market. What is the difference between the two? Below we will step by step to reveal the answer one by one:
First, several reasons for the unhealthy air and its importance analysis:
1. Oxygen content: The oxygen content is lower than the health needs of the human body. It is not necessarily a problem, but it is a problem in a closed space. Too hot and cold, we don’t want to open the window. It is afraid of wasting air conditioning when it is hot. It is cold and windy. It is afraid that the cold wind will enter the house and cause the room to be too cold. Or we can close the door and close the window for eight hours at night. Low, the consequences are dizziness, nausea, etc., the impact on health is inevitable (warm reminder: some people have no obvious reaction to the body of hypoxia, in fact, it is still harmful to the body, it is certainly not good for the accumulation of time).

2. Harmful micro particles (PM2.5): refers to particulate matter with a diameter of 2.5 microns or less in the air. Needless to say, it is extremely harmful and is the current top health killer. Particles smaller than 2.5 microns may enter the blood vessels directly because these particles themselves are often enriched with harmful substances and are one of the main sources of carcinogenesis, and particles larger than 2.5 microns will damage the respiratory system such as the lungs.

3, harmful gases: formaldehyde, benzene, hydrazine and other harmful gases. The problem of formaldehyde has little effect on plant greening. (Can plants breathe tens of hundreds of cubic meters of air per hour like a purifier?), their harm to the human body is very large, according to research in recent years, most of The rooms of leukemia patients have just been renovated.

4, bacteria: pay attention to hygienic habits and dry ventilation, bacteria is not a big problem, only pay attention when the flu season or respiratory infections. The human body has a certain resistance to bacteria, and the general damage caused by it can also be repaired, and the human body has almost no resistance to PM2.5 and formaldehyde.

Second, the function comparison between fresh air system and air purifier:

(1) The fresh air system is an air replacement device that can realize uninterrupted circulation and purification of indoor and outdoor air. It can directly change fresh air without opening the window and remove indoor harmful gases and dirty air for 24 hours without interruption. The indoor environment is natural, fresh and clean so that your living room is truly energy-efficient and environmentally friendly.

1. Solve the problem of oxygen content by pumping in the air;
2. Use heat exchange to solve the problem of energy loss during ventilation;
3. Solve the PM2.5 problem with a filter membrane.

The “Olans” fresh air system has patented technology to effectively improve the filtration effect of the filter. Patented technology, automatic cleaning filter, continuous use for 20,000 hours, no need for manual maintenance, eliminating the secondary pollution and damage caused by replacing the filter, reducing user cost.
(2) Air purifier
The air purifier filters the indoor air in the direction of the inner circulation. In a properly enclosed environment, the strong airflow through the air outlet accelerates the indoor airflow, so that the hair, dust particles, etc. that originally float in the air accelerate with the airflow and are filtered by the strong suction of the filter structure. Thereby achieving a purification effect.

1, can not solve the problem of oxygen content, need to open windows and doors regularly;
2. There is no energy loss problem;
3, using high-voltage electrostatic adsorption, ultraviolet light, photocatalyst, negative ions, and plasma to solve a variety of different technologies to solve harmful micro-particles, harmful gases, bacteria, and other issues, but some of them are flicker.

High-Efficiency Particulate Air Filter (HEPA) is one of the most popular technologies used in air purification. As for other so-called technologies: negative ion function (contaminants are easy to adhere to indoors, and the effect of solving particles is very limited, the sterilization effect is controversial) has the risk of ozone; electrostatic filtration is also likely to produce excessive ozone, which is harmful to human health.

Moreover, the air purifier is often placed at the corner, and its purification range is generally about 2 meters in diameter. The air in other places is difficult to be “captured” by the purifier.

If you choose an air purifier, you need to open the windows and doors regularly. Every time you open the doors and windows to change the air, it is the beginning of pollution.

Fresh air systems include top air and wall mount. The top air supply is mainly used for houses that have not been renovated, and is installed in the ceiling; the wall-mounted fresh air is mainly used for houses that have been renovated. The fresh air system works as follows:

Top air supply fresh air system: Install new air blowers and exhaust ducts in the kitchen or bathroom, and install air inlets in the bedroom and living room. When the machine is running, the original air in the room is exhausted, so that the indoor air generates a negative pressure. The outdoor fresh air enters the room through the air inlet under the action of the indoor and outdoor air pressure difference, thereby achieving the purpose of indoor ventilation and ventilation.

Air purifier health function: air conditioning disease

Air purifier health function: air conditioning disease

Watermelon, WiFi, air conditioning, the three “treasures” that are known as summer, is the favorite of the homeowners. Working, studying, and eating in an air-conditioned room during the hot summer is a very pleasant thing. However, the air-conditioned room is relatively sealed, the air does not circulate, and the indoor furniture volatilizes pollutants. After continuous accumulation, many harmful gases exceed the standard, which may cause cough, headache, salivation and other symptoms, commonly known as “air conditioning disease.”
So what role can the Yikang negative ion air purifier play in the summer?
01 Prevent bacterial infection
Summer is the season of bacterial reproduction. In addition to directly entering our body, these bacteria can enter our body by attaching particles and dust with a diameter of less than 5μm. Even by talking, coughing, sneezing, etc., we can easily put the mouth and throat. Pathogenic microorganisms in organs and lungs are transmitted to other people through the air, and some epidemics are caused by the spread of germs. The sterilization function of the air purifier can solve this problem very well, so if someone has a cold or cough in the house, it is recommended to turn on the air purifier.
02 Prevention of “air conditioning disease”
In summer, the temperature is high, and many people can’t wait to stay in the air-conditioned room for a day. Although the air-conditioning is cool, the doors and windows are closed all day long, not only the humidity is very large, but also the indoor air is not circulated, causing indoor air pollution, which will cause various discomforts. When turning on the air conditioner, it is recommended to turn on the air purifier.
03 purification indoor formaldehyde
The increase in temperature will increase the volatilization of indoor pollutants. According to the statistics of the health department, the concentration of formaldehyde and benzene released by furniture increases by 0.15 to 0.37 times for every degree of humidity increase. The pollutants in the home are not released in a short time, and it takes 15 years to completely release the clean. Many indoor air purifiers in addition to formaldehyde can help us remove harmful substances such as formaldehyde so that users can have a fresh indoor environment in the summer.
04 Prevention of second-hand smoke hazards
Many people like to smoke, which has buried the hidden dangers of second-hand smoke for their families. Second-hand smoke contains hundreds of known toxic or carcinogenic substances, including formaldehyde, benzene, and vinyl chloride. The concentration of many carcinogens and toxic chemicals in second-hand smoke is higher than that smoked by smokers themselves. The purifying function of the air purifier can remove these harmful substances well and provide a healthy indoor living environment for everyone.

Talking about the history of air purifier development – those things you don’t know

Talking about the history of air purifier development – those things you don’t know

Air purifiers, also known as “air cleaners” and air purifiers, mainly solve indoor air pollution problems caused by renovation or other reasons.

The release of pollutants in the air is characterized by persistence and uncertainty. There are many different technologies and media in the air purifier, which can adsorb, decompose or convert various air pollutants (generally including dust, pollen, odor, formaldehyde). Such as decoration pollution), so that it can provide users with clean and safe air. Therefore, air purifiers have become the internationally recognized best way to improve indoor air quality.

So how does the air purifier appear on the technological stage?

Origin of the predecessor · Originated from firefighting purposes

In 1823, John and his friend Charles Dean invented a new type of smoke protection device that allowed firefighters to avoid smoke during firefighting.

In 1854, a man named Johns Tenghaus learned that adding charcoal to the air filter could filter out harmful and toxic gases from the air, so after several attempts, the invention was based on the invention of Dean. More. It can be seen that the predecessor of the air purifier originated from fire protection purposes.

During the Second World War, the US government began research on radioactive materials and wanted to develop a machine to filter out all harmful particles to keep the air clean and scientists can breathe, so the HEPA filter came into being.

In the 1950s and 1960s, HEPA filters were very popular because of the popularity of many shelter design and construction personnel.

Reform and innovation · first-generation air purifier

However, such filters can only target toxic gases and odors in the air and are basically useless for bacterial viruses. In the 1980s, new air purifiers were born, which can not only be used to eliminate odors but more importantly, It can effectively remove bacteria, dust, pollen, etc. from the air to purify the air.

Fiery market, many brands compete

With the passage of time and the growing development of science and technology, purifiers have evolved in many versions, and every technological innovation has brought people a better experience than ever before.

Commonly used air purification technologies include: adsorption technology, photocatalytic technology, HEPA filtration technology, negative oxygen ion technology, low temperature asymmetric plasma air purification technology, molecular complexation technology, electrostatic dust collection technology, reactive oxygen technology, room temperature catalytic oxidation of formaldehyde and Catalytic sterilization, etc.; material technology mainly includes: photocatalyst, activated carbon, synthetic fiber, HEAP high-efficiency material, negative ion generator, etc. At present, the existing air purifiers in the domestic market are mostly compounded, and various purification technologies and material media are used at the same time.

Redefining · excellent products to break the chaos

Advanced science and technology are integrated into the development of air purifiers to improve human air quality step by step and provide a guarantee for a better life for human beings. The state also issued a policy response to the development of the empty net industry. At that time, the development of the empty net industry was bright, and many large and small enterprises rushed to join it.

However, the increase in quantity has also caused bad consequences. The air purifier brand in the leasing market is mixed, the purification principle is varied, and the purification effect is mixed. The original national standards cannot effectively cover the technology, types, and needs of the air purifiers in the new era, leading to some enterprises. Exaggerated propaganda or false propaganda for the sake of profit.

Previously, air purifier products were not uncommon due to false standard parameters, false publicity, and after-sales service; industry standards were old and chaotic, which has caused many consumers to start distrusting and not accepting the current empty net products. With the introduction of the new national standard, users renting air purifiers will also be “based on evidence” and will not be blind again. To a certain extent, the accelerated purging of the air purifier rental market has been promoted, and the substandard cottage products have gradually been eliminated, and some competitive machines have gradually emerged and entered the consumer’s field of vision.

Future market · Improving the environment is an urgent task

The development of air purifiers in China has gradually become a mature industry. In 2019, the challenges posed by the air purifier market are unprecedented. Only high-quality and conscience industries can continue to survive in the net industry. Huggins owns air purifiers from international brands such as Blueair, Austin, and IQAir to provide air purifier rental quality services for enterprises and families.

In addition, the environment provides the necessary resources and conditions for our survival and development. Regardless of the future market, protecting the environment, reducing environmental pollution, and curbing the trend of ecological deterioration are the basics of human civilization and scientific and technological development.

Can the air purifier really eliminate formaldehyde? Is this high technology or IQ tax?

Can the air purifier really eliminate formaldehyde? Is this high technology or IQ tax?

The same is the air purifier, how the price is very different?

Haze and formaldehyde have caused people to panic about air quality and health, so air purifiers have gained a foothold in the market.

Some people say that the air purifier market is really too profitable, taking advantage of the public’s panic about smog and formaldehyde, as well as the lack of understanding of the purifier, the price of the sky. The ordinary things are priced at five or six thousand, and some brands even sell the price.

1. What is the internal structure of the air purifier?

According to the internal analysis, the three components constitute a simple air purifier, which is a common filter, HEPA net, deodorizing net.

The first part, the ordinary filter. Similar to the air conditioning filter, it filters coarser particles and can be washed.

The second part, the HEPA net, is also known as the dust net. It is used to filter small particles, bacteria, and other substances, not water.

The third part, deodorizing net. Each brand of this layer has many different names, named high, but the main components are basically activated carbon, many businesses will compound some things to improve performance and extend life. The purpose is to remove odor and harmful chemicals such as formaldehyde and benzene.

These three components, together with a plastic case and a fan for air in and out, have become a “high price” purifier. So, the price of four or five thousand or even tens of thousands of things, take a look at it, but it is the composition of these things, do you say that this is the IQ tax?

2. Can the air purifier remove formaldehyde?

After the renovation of the new house, the most troublesome problem is the formaldehyde problem. Some people choose to ventilate for a while, but for the owners who are in urgent need, they will choose the air purifier, because many brands of air purifiers use the slogan of “clearing formaldehyde” to attract consumers, then the air purifier removes formaldehyde. Is it effective?

First of all, if the new house has just been renovated and moved in, don’t expect the air purifier to eliminate formaldehyde in a short time, which is unscientific.

Because during the decoration, many furniture and other materials use a lot of decoration materials containing formaldehyde, the pollution of formaldehyde will be very serious, especially in the summer of high temperature, formaldehyde will be evaporated quickly unless you open dozens of air at the same time. filter.

Second, the release cycle of formaldehyde ranges from 3 to 15 years. Formaldehyde is completely eradicated and can only be controlled within a safe range, and an air purifier can achieve this.

According to the “indoor air quality standards”, after closing the doors and windows for 1 hour, the indoor formaldehyde safety range value is ≤0.08 mg/cubic. However, according to children’s response to formaldehyde, it should be less than 0.06 mg/cubic.

3. How to judge whether the air purifier is qualified?

In the room where the doors and windows are closed, the air purifier controls the indoor formaldehyde concentration to ≤0.08 mg/cubic within 12 minutes to be truly qualified.

In addition, Xiao Bian once again reminds everyone, do not rely on too much and believe that air purifiers can eliminate formaldehyde, the best way to reduce formaldehyde damage is ventilation and green plants.

4. How long does the air purifier open in a day?

If you are staying in a new home and have a family stay indoors, it is best to open it 24 hours and open the air purifier to prevent the formaldehyde concentration from exceeding the standard. Some people will worry about whether the air purifier will burn out. After all, it is a machine. As long as the air purifier you buy is a quality qualified product, it will basically not burn out, because it has the function of thermal protection of the fan.

5. How long does the air purifier change the filter?

It can be replaced according to the color of the filter of the air purifier. If the filter is black, it means that a new filter cartridge needs to be replaced. However, there are also smart air purifiers on the market that automatically remind you to replace the filter cartridges, if you can buy smart products for convenience. The timely replacement of the filter element of the purifier can extend the life of the product and also achieve the purification effect.

Beijing School Gets Air Purifier

Beijing School Gets Air Purifier

According to local education authorities, Beijing plans to install air purifiers as part of school building standards to cope with frequent smog weather in the capital.

The Beijing Times said Tuesday that government departments, including the Beijing Municipal Bureau of Education (BMCE), are drafting standards for school construction in the city, including the installation of air purifiers.

In response to severe smog forecasts, Beijing issued two red pollution warnings this winter.

Xi’an said the effectiveness of air purifiers in compact classrooms had not been determined, adding that schools could install air purifiers on their own.

“Installation of water purifiers in classrooms is to ensure the safety of students and requires parental approval,” Xi’an said.

Parents shrouded in Beijing’s dangerous smog have repeatedly called on primary and secondary schools to install air purifiers in their classrooms, but schools refuse to accept the approval of the education authorities. Their children’s school, but their efforts were rejected.

Well-funded kindergartens and elementary schools have installed air purifiers in their classrooms, but some schools are unable to buy them because of insufficient budgets.

Hao Xianjun, chairman of Shijingshan School, opened the air purification system during the Pollution Day battle against the Beijing Times. The concentration of PM2.5 (floating particles less than 2.5 microns in diameter) announced that it would be reduced to less than micrograms. When a new teaching building is built every cubic meter this year, Shijingshan Experimental Junior High School will take the lead in installing such a system.

During the fourth session of the 12th People’s Political Advisory Committee of Beijing, many consultants submitted a proposal for schools to deal with smog.

Pu Zhe, a member of the committee, said that the education department would set up a special smoke fund, set up an air purification system in schools, set up what types of air purifiers and start a comprehensive procurement platform. He said local regulations should be introduced.

Beijing-based Mirror told committee members Thursday that at its meeting on Thursday, primary and secondary schools are expected to extend winter holidays and reduce summer holidays as smog covers the capital in winter. Beijing primary and secondary schools for about a month.

High pollution levels are associated with an increased risk of heart attack

High pollution levels are associated with an increased risk of heart attack

High levels of pollution may increase the risk of heart disease within six hours of exposure, according to articles published online in the British Medical Journal. However, the risk will not increase in six hours.

Given the nature of the temporary increase in risk, it is assumed that a heart attack will occur anyway and trigger completely within a few hours, which is known as the short-term elimination (or “harvest” effect of pollution.

An established study concludes that high levels of pollution are associated with premature death from heart disease, but the association with increased risk of heart disease is not clear, the authors said.

Higher levels of PM10 and NO2 are well-known signs of traffic-related pollution, Bhaskaran said.

The most effective way to avoid these problems is to place an air purifier at home, and Olans chooses quality.

Purchasing Skills and Cleaning and Maintenance Skills of Air Purifiers

Purchasing Skills and Cleaning and Maintenance Skills of Air Purifiers

Outside the house, the air we inhale, with factories, car wear out fumes, haze is furthermore very serious, a lot of people will certainly have respiratory disease. Of which hid in the residence would not breathe in the air of minimal quality bar, indoor airflow pollution could be the same severe, it can not get dismissed. Today we take a peek to buy an atmosphere purifier and air cleanser share tips to completely clean and preserve.
Acquire air purifiers skills to be able to talk about
1, based on the selected area air purifier. If if you’re in an area in which a relatively large quantity of wind air filter should be chosen just as large as possible versions, which could introduce products via judgment and choice.

safety. Home air purifiers housing, movement plus purification technology related to being able to the safety with the surroundings purifier. Purification technology is most beneficial found in nature since positive and negative ions.
3, note that typically the air purifier works. Cleansing is: physically, electrostatically, chemically, negative ion mode, plus composite mode. Under regular circumstances, the principles associated with simultaneous use of numerous purification purifying effect may be better yet.

4, airflow purifier life and easiness of maintenance. In buy to prolong living regarding the air purifier, get home air cleaners to need time to select a new playback function of filter and filtration bile.
Surroundings purifier to wash and preserve
Air purifiers and normal water purifiers, like, need in order to be cleaned regularly, and even some need to impact the filter, consider the particular gall to keep its cleansing effect. Home air cleaner maintenance and even maintenance, depending on the particular needs of different manufacturers, different types of residence air cleaners to become.
Air purifier dust filtration system dust collection plates or even regular cleaning, general cleaning up once a week, or perhaps the foam plates together with a dry cleaning cleansing soap after use, to maintain the airflow smooth plus sanitation. Fan, when typically the upper electrode more particles, to be clear, common maintenance once every 6 months. Available long-haired clean in addition to the particular electrodes and the particles on the wind vane. When the air filter is not really in use, needs to be cleaned after setting into the box, saved in a ventilated, dry up the place. Usually should spend attention on moisture, as a way not to reduce the particular use of efficiency as a consequence to damp or ruined.
Basically, every day found in sleep eight hours or perhaps so, as well as work, the period at home much more compared to 10 hours and select an air purifier, to produce a comfortable home environment in their own and their very own families and keep healthful. These are typically the optional home air purifiers small sequence presentation skills sharing in addition to an air cleaner to thoroughly clean and maintain content.
