A special force – pigeons – appeared in the British capital over London. They carry air quality detectors to detect real-time detection of pollutants such as nitrogen dioxide and ozone over the city. The three-day event, called the Pigeon Air Patrol, aims to raise public awareness of air pollution.

Agence France-Presse reported that on the 16th, the last day of the event, 10 well-trained pigeons flew from the Primrose Hill in the wealthy area of ​​northern London to fly over London.

One of the pigeons was tied to a lightweight air quality tester and another pigeon was tied to a global positioning satellite system. An air quality detector weighing only 25 grams records pollutants such as nitrogen dioxide emitted by the vehicle. Local residents can get the air pollution index of their region by paying attention to the activity account on the social networking site.

According to Pierre Deca Nou, the creative director of the event and the marketing agency Le Bieyang, the event was inspired by the extensive use of pigeons during the war. During the two world wars, pigeons were used to transmit information and save lives. The flying height of the pigeons is relatively low, between 30 and 46 meters, and the speed is as high as 129 kilometers per hour. Deca Noir believes that it is feasible to have a mobile air detector with a pigeon, and that the pigeons are not affected by traffic congestion in London.

Gary Fuller, an air pollution expert at King’s College London, also believes that it is a good thing to let the ‘doing nothing’ pigeons in Trafalgar Square ‘start working’. ‘This is the first time I’ve heard that urban animal-borne detectors provide us with air pollution data.’

According to CNN, the ‘Dove Air Patrol‘ campaign is actually launching a larger event for a French air quality testing company. The company is recruiting 100 Londoners to carry air quality detectors to detect air pollution at various locations in London. Interested parties can pay approximately £79 to £99 on the crowdfunding platform. On the 16th, 60 people have already paid.

‘Fog’ hat is difficult to pick?

‘The air we need to breathe every day weighs 20 kilograms,’ said Roman Laconb, CEO of the French company. ‘Never millions of people worldwide die from air pollution every year, but because the pollutants are not visible, we are very Hard to recognize the problem.’

During the ‘Dove Air Patrol‘ event, most parts of London are suffering from moderate to severe air pollution, with Battersea being the most polluted.

A survey conducted by King’s College London last year showed that air pollution caused 9,500 Londoners to die.

British Labor Party leader Jeremy Corbin made a severe question on Prime Minister David Cameron in the parliament on the 16th, and air pollution is the focus of the Corbin attack.

According to data cited by Corbin, 400,000 people die each year from air pollution in the UK, bringing 20 billion pounds of economic losses to the country.

Corbin said that ‘sadly is that in the UK can fulfill its obligations, before the pollution level will be reduced, there will be 500,000 people will die due to air pollution.

According to Agence France-Presse, the level of nitrogen dioxide pollution in London ranks first among European capitals. In 2014, the UK was criticized by the European Commission for failing to fulfill its obligation to reduce air pollution.

Recently, strong smog has occurred in many places in Europe. According to the chart provided by the real-time air quality index testing website on the 18th, the Western European countries Britain and France are the hardest hit areas of smog; some cities in Eastern Europe, Poland and the Czech Republic, have more smog. The air quality in Moscow, the capital of Russia, is particularly bad, and the air pollution index is staggering.

>>London

The toxic fog hits the scene of ‘fog’

According to the British ‘Mirror’ reported on the 18th, health experts warned that the virus-like fog blowing in the direction of the European continent is sweeping across the UK and may lead to a health crisis. Thousands of people may fall ill, and people with weak constitutions may be in danger.

High pressure over the sky makes pollution impossible to spread

The virus caused the virus to sweep across the UK, and the alarm level in many places in the UK has risen to level 9, with level 10 being the highest. Expert Bolton believes that the poisonous mist is blowing from the direction of the European continent, and the warm weather makes the traffic pollution more serious. He said: ‘There is a high pressure over the UK, which causes pollution to spread.’

London has returned to the ‘Fog Capital’ hat, and the ‘Fog Capital’ scene reappears. The southeastern and central parts of London are covered with a turbid fog, ‘like a fairyland.’ The entire city is shrouded in a hazy smog, with low visibility and unclear high-rise buildings in the distance. On the street, pedestrians wear masks and the car is covered with dust.

Last year, 1.6 million people were caused by toxic fog

What worries the British people is that these are the virus-like fog. According to the ‘Mirror’ report, according to data from the government health consultant, last year, 29,000 people in the UK died of air pollution. This figure is 16 times the number of deaths from road traffic accidents in that year and twice as many as the number of deaths from breast cancer.

On the 18th, British officials warned that ‘toxic fog may cause serious health problems, and children and the elderly with asthma, heart disease or lung disease need special attention.’ In 2014, similar toxic fog pollution incidents broke out in the UK, and many people felt unwell after inhaling haze. The charity ‘British Asthma’ said that 1.6 million people were caused by toxic fog.

>>Paris

The smog enveloped the Eiffel Tower was ‘launched’

According to the British ‘Guardian’ reported on the 18th, in addition to the United Kingdom, France is also shrouded in smog. The soaring air pollution situation has attracted the attention of the French government and promptly introduced a number of emergency measures.

The Eiffel Tower ‘disappears’ in the middle

In December 2013, the smog covered the Big Wild Goose Pagoda in Xi’an. The netizen once said that ‘Is the Big Wild Goose Pagoda launched?’ Today, the Eiffel Tower in France was also ‘launched’. On the 18th, the Eiffel Tower ‘disappeared’ in brown smog. Netizens have commented: ‘If you can’t see the Eiffel Tower, how can you believe that this is Paris?’

According to Agence France-Presse, in Paris, air quality monitoring agencies use PM10 to measure pollution levels. The safety margin of the PM10 was set at 80 micrograms per cubic meter, but the PM10 in Paris once reached 180 micrograms.

The French government introduced a number of emergency measures

According to the British ‘Guardian’ report, on the 18th, the French government quickly introduced emergency measures, such as reducing the speed limit of motor vehicles (20 km / h), prohibiting the burning of garbage. In addition, the French government has taken other urgent measures, including allowing only one out of every two cars to enter Paris and launching free public transport.

During the smog last year, the French government adopted single and double restrictions, and all public transportation in the Paris area was free for four consecutive days.

>>Moscow

The smell of the air, the public complained that the smell was bad.

According to the chart provided by the real-time air quality index testing website on the 18th, the air quality in Moscow, the capital of Russia, is particularly bad, and the air pollution index has reached an astonishing 452. On the 18th, there was haze in the north of Moscow, and the air was filled with stench, Moscow citizens. And tourists once again complained about the decline in air quality.

The smog in Moscow has a distinctive feature, always filled with unpleasant smells, and the whole city is shrouded in a smog of pungent, stinky eggs. At the end of last year, there was a rare weather condition called ‘Smelly Egg Cloud’ in Moscow. The air emitted the stench of sulfides; the visibility was very low, and even the sun could not be seen.

PM2.5 promotes aging in the brain, and older people are more likely to have a stroke

PM2.5 promotes aging in the brain, and older people are more likely to have a stroke

air ioniser,hepa air purifier,coldcatalyst air purifier

According to the Science Daily, air pollution, even moderate pollution, has been seen as a risk factor for increased stroke. A recent study by scientists at the Beth Israel Deaconess Medical Center in Boston, Massachusetts, and Boston University School of Medicine has shown that long-term exposure to air pollution can impair brain structure and cognitive function in middle-aged and elderly people.

In an article published in the journal Stroke, the researchers investigated more than 900 subjects in the Framingham Heart Study and found evidence of smaller brain structures and more subtle cerebral infarctions. It is a “static” ischemic stroke that is caused by blockages in the blood vessels that supply the brain.

The study assessed how far the subject’s living quarters were from the main road and used satellite imaging to assess the longer-term exposure of fine particles to suspended particles, which are 2.5 meters in diameter, also known as the 2.5-meter-diameter particles. For PM2.5. These granules come from many sources, including power plants, factories, trucks, motor vehicles, and burning wood. They can go deep into the lungs, and other studies have shown that PM2.5 is associated with an increasing number of cardiovascular patients in the hospital, such as heart disease and stroke.

‘This is one of the first studies to investigate the correlation between air pollution and brain structure,’ says Elissa Wilker, a researcher at the Cardiovascular Epidemiology Laboratory at the Israel Women’s Deacon Medical Center. He is also a member of the Epidemiology and Danger Program exposed by the Harvard Chen Zengxi School of Public Health (HSPH) Department of Environmental Health. ‘Our findings suggest that air pollution is closely related to the insidious structural brain aging effects, even in individuals without dementia or stroke.’

Participants in the study were individuals over 60 years of age who did not have Alzheimer’s disease and stroke. The assessment included brain capacity – age markers associated with brain atrophy; hippocampal volume, which reflects changes in the brain region that control memory; high density of white matter, which can be used to measure pathology and aging; and hidden Cerebral infarction.

The study found that PM2.5 in the air increased by 2 μg/m3 – a common growth in New England and New York, as well as in large cities such as New York – leading to an increased likelihood of occult cerebral infarction and reduced brain capacity. This effect is equivalent to about one year of brain aging.

‘These results are an important step toward helping us understand what’s going on in the brain,’ Wilk said. ‘As for the possible mechanisms by which air pollution affects brain aging, it is still unclear, but systemic inflammation caused by fine particles deposited in the lungs is likely to be very important.’

‘This study shows that PM2.5 in the air increases by 2 μg/m3 – a common area of ​​PM2.5 in the US metropolis – people living in heavily polluted areas are more likely than people living in lightly polluted areas. Brain capacity is an average of 1 year old, and their risk of developing a static stroke is 46% increased,’ said Sudha Seshadri, a professor of neurology at Boston University School of Medicine and a senior investigator of the Framingham Heart Research. .

‘This is really worrying because we know that static stroke increases the risk of dominant stroke and development of Alzheimer’s disease, walking problems and depression. We now plan to investigate the long-term effects of air pollution, which is more sensitive to MRI. (MRI) measurements, brain atrophy, and other risks, including the effects of stroke and senile dementia.’

The smog is still terrible, smoking indoors causes PM2.5 to directly explode

The smog is still terrible, smoking indoors causes PM2.5 to directly explode

electronic air purifier,electrostatic air purifier,air purifiers canada

The haze and the low temperature, some smokers will stay at home to smoke. If you don’t open the windows and doors, the smoke will haunt the house in a while. The reporter found that if the number of cigarettes is ignited at the same time, the indoor PM2.5 will directly burst into a thousand! …is terrible, don’t smoke in the house for everyone’s health!

Experiment

Experiment in a room of approximately 20 square meters and close the doors and windows during the experiment. Test air quality in different states.

Experiment equipment

Experimental equipment: two packs of cigarettes, lighters, laser detectors, laser detectors can detect PM2.5 concentration and formaldehyde concentration in the air.

Experiment procedure

When the cigarette is not lit, the indoor condition is PM2.5 at around 230.

Experiment analysis

Note: Since the meter is more sensitive, the value fluctuates within a certain range, and the numerical interval represents the lowest value and the highest value in this state. According to the air pollution index level, the PM2.5 value is mildly polluted at 101-150, the 151-200 is moderately polluted, the 201-250 is heavily polluted, and the above 250 is severely polluted. According to the indoor formaldehyde content classification, when the indoor content is 0-0.05, it belongs to the safety level, 0.06-0.08 belongs to the general level, and 0.08 or more belongs to the excessive standard.

Experimental result

In terms of PM2.5 concentration, the experiment found that when the cigarette was ignited, the concentration began to rise. When igniting a cigarette (such as smoking in a room), the local concentration of PM2.5 exceeds 250 μg/m3, that is, the local air quality reaches a serious level of pollution. When igniting 10 cigarettes (such as many people smoking at indoor gatherings), the PM2.5 concentration is stable at around 700 μg/m3, and the instantaneous PM2.5 can reach 1000 μg/m3, which is the highest value of the sputum.

In addition, the door and window ventilation was not opened during the experiment, which means that if the indoor smoking continuously, the PM2.5 concentration will be in a cumulative state. At the same time, after the cigarettes are burned out and the smoke is ‘invisible’, the value will drop rapidly. For example, after 20 cigarettes are burned out, the value no longer lasts between 900 and 1000 mg/m3, but falls to the range of 700-800 mg/m3.

The formaldehyde concentration data shows that the formaldehyde data will increase after the cigarette is ignited. When the PM2.5 concentration was increased to about 600 μg/m3, the formaldehyde content increased to 0.18 mg/m3. When PM2.5 to 1000 μg/m3, the instantaneous formaldehyde concentration can reach 1 mg/m3. In other words, smoking indoors will increase the concentration of formaldehyde.

Expert: Smoking in the haze days is a ‘health’ for health hazards

Yang Yue, director of the Department of Thoracic Surgery, Peking University Cancer Hospital, said that smoking and smog have a commonality to the human body. They are all breathing system without oxygen exchange; therefore, smoking indoors in smog can be said to be ‘additional.’

Experts said that people in the haze are used to closing the doors and windows. If you smoke indoors, the air will not circulate and the concentration will be very high. It can be seen that the haze day itself makes the oxygen content lower. At this time, the smoking increases the anoxic state of the cardiovascular and cerebrovascular system, forming a heavy diaphragm.

Since 2000, tumors have surpassed cardiovascular and cerebrovascular diseases, becoming the world’s number one ‘death’ – more than 5 million people die each year from cancer. In order to stimulate the determination and expectation of global cancer to overcome cancer, UICC launched the ‘World Cancer Day’ in 2000. Just this year, it released two amazing statistics, once again ringing the anti-cancer cancer control. Alarm bell.

News 1: According to experts from the Beijing Cancer Prevention Office, the incidence of lung cancer in Beijing increased by 43% in 10 years, and the age of onset of lung cancer tends to be younger; News 2: China’s first assessment of PM2.5 long-term exposure to the public The research report on the impact of health has been released. The report pointed out that atmospheric PM2.5 pollution has caused over 257,000 deaths in 31 provincial capital cities or municipalities across the country, and the excess mortality rate is close to 1‰. In the case of excess death, a considerable part is lung cancer.

Lung cancer, China’s morbidity and mortality are the first cancers, and the mortality rate is still rising at a rate of 4.45% per year. According to a sample survey of the third cause of death in China in 2006, lung cancer accounted for 22.7% of all cancer deaths. Zhi Xiuyi, director of the Department of Propaganda and Popularization of the Chinese Anti-Cancer Association and director of the Department of Thoracic Surgery at the Beijing Xuanwu Hospital, vividly described the lung cancer as a disease caused by smoke, atmosphere, oil and gas, and gas.

Smoking, environmental pollution, occupational exposure, chronic lung disease, and genetic susceptibility are the leading causes of lung cancer. Although smoking has always been considered to be the first cause of lung cancer, several studies in recent years have shown that with the implementation of tobacco control measures, the rising incidence of lung cancer caused by smoking is clearly controlled, but lung cancer is positively related to environmental impact. The incidence rate has shown a rapid upward trend.

In areas with high incidence of smog in Beijing and Tianjin, the incidence of lung cancer is significantly higher than the average in China. Wang Ning, deputy director of the Beijing Cancer Prevention Office, said that the incidence of lung cancer in Beijing increased from 39.56/100,000 in 2002 to 63.09/100,000 in 2011, which is far higher than the Chinese average. The incidence of lung cancer in Tianjin is about 60/100,000, and one-fifth of new cancer patients are lung cancer patients, and they are obviously younger.

Last year, the International Agency for Research on Cancer (IARC) identified air pollution as a carcinogen. Strictly speaking, atmospheric particulate matter, also known as PM2.5, is a confirmed human carcinogen. It is imperative to pay attention to health!

When it comes to air pollution, people always think of outdoor pollution such as haze and sandstorms. According to a joint Elab survey, nearly 88% of respondents believe that indoor air quality is good. But in fact, indoors is the hardest hit by air pollution, and its damage can even reach 8 times more than outdoor. According to WHO data, the number of deaths caused by indoor air pollution is as high as 3.8 million per year.
To know that the average person spends more than 80% of the time indoors every day, how can we improve indoor air quality and have a healthy breathing environment?

The generation and countermeasures of PM2.5 in residential interior

Portable Air purifier,Aroma and essential oil diffuser,Mist humidifier

With the development of society, the whole people pay more and more attention to health. Since the reform, China’s economy has developed rapidly, but at the same time, air quality has deteriorated due to pollution caused by transportation, construction, agricultural activities, combustion sources and particulate matter. According to medical statistics, people need to breathe more than 20,000 times a day. How to improve the living environment and reduce people’s exposure time in harsh air has become the first task to study healthy buildings.

First, the background of outdoor PM2.5

Air pollution is an environmental pollution that is closely related to everyone’s health. Among them, PM2.5, which is a particle with a diameter of 2.5 microns or less, can penetrate directly into the lungs and enter the blood through the lung barrier due to the complex mixture of solid and liquid organic and inorganic substances. Its concentration is often used as air pollution. synonym. In recent years, various urban agglomerations and regions have taken measures to improve air quality.

According to the results of the indoor PM2.5 pollution big data released by Tsinghua University in 2019, there is a positive correlation between indoor PM2.5 concentration and outdoor concentration. Sometimes indoor PM2.5 is higher than indoors. At the same time, the results also show that the indoor level of the office environment is slightly better than the living environment. A lot of statistics suggest that about 80% of the time in the building is in the building, and then subdivided, about 30% is in the office building, and 50% is in the residential home. So let’s analyze how indoor PM2.5 comes from in the living space and how to deal with indoor PM2.5 more economically and reasonably.

Second, the source analysis of indoor PM2.5

In the building interior, as a space, the source of PM2.5 inside is roughly divided into two categories: indoor production and outdoor input. Among them, indoor self-production generally includes cooking, smoking, and personnel activities. Outdoor input sources include the introduction of fresh air systems, the penetration of door and window systems, and the introduction of personnel access.

Heating
In areas where decentralized heating is used, gas fireplaces are often used in residential households, even with conventional coal combustion, which is heated by burning calories from fossil dyes. And this combustion process will produce a large amount of nitrogen oxides, which will greatly deteriorate the indoor PM2.5 condition if it cannot be eliminated promptly and effectively.

2. Cooking
When we cook at home, there are two processes that produce PM2.5. One is that gas stoves burn natural gas or even particulate matter produced by gas. The second is cooking, especially the soot particles produced by frying and frying in Chinese food. According to the experimental research on four cooking methods of steaming, boiling, frying and frying according to the environmental protection public welfare organization ‘Natural University’, boiled corn, steamed steamed bread and potato chips were tested under the condition that the doors and windows were closed and the range hood was not opened. , PM2.5 produced by four cooking methods. The data showed that ‘cooking’ had a smaller effect on PM2.5, while ‘fried’ and ‘fried’ had a significant effect. Among them, “fried” even reached the ‘explosive table’ level of 787 μg/m3.

3. Smoking
In addition to being a bad habit of smoking, smokers in the enclosed indoor space are also the main source of indoor PM2.5. Once there was laboratory test data, a cigarette burned completely, producing 0.62 grams of particulate matter, of which PM2.5 accounted for about 30% to 40%, about 0.19 to 0.25 grams. If you smoke three cigarettes in a 100 square meter room, the concentration of PM2.5 will reach 955μg/m3, and the standard will reach 20~30 times!

4. Personnel activities
Personnel activities include walking, coughing, and secondary dust generated during housework. It should be specially noted that the conventional vacuum cleaner has the function of removing dust, but in fact, the vacuum cleaner is just one of the important sources of indoor PM2.5. The principle of the vacuum cleaner is to use the vacuum negative pressure caused by the electric motor to inhale dust and air in the room, and filter it through the filter to discharge the clean air. The filter in the conventional vacuum cleaner on the market can only filter out large particles of dust, such as dusty pompons that can be seen by the naked eye, but cannot be filtered for fine particles such as PM2.5. Thus, the PM2.5-rich particles are again discharged by the vacuum cleaner. Considering the air disturbance caused by air intake and discharge, PM2.5, which may have been adsorbed and settled, is accelerated by the vacuum cleaner. Of course, there is also a solution to use a high-efficiency vacuum cleaner that filters PM2.5. Similarly, the relatively low-level sweeping robots in the past two years may remove large particles of dust visible to the human eye. However, if the filtration efficiency is insufficient, the indoor PM2.5 can be twice diffused. The principle is the same as that of a conventional vacuum cleaner.

5. Fresh air system
The home fresh air system is undoubtedly one of the more familiar configurations of healthy living in recent years. The main function of the fresh air system is to filter the fresh outdoor air into the room. Then the problem comes. Fresh air refers to the outdoor air rich in oxygen, and even if the outdoor air is filtered by PM2.5, some PM2.5 that has not been filtered is sent into the room, so the new system is from a certain degree. In fact, it is actually an input source for indoor PM2.5, even if some fresh air systems have exhaust function.

6. Door and window system
The windows and doors on the market are now very airtight and can block the flow of air. However, PM2.5, which is less than 2.5μm, can penetrate into the room through the fine gap of the door and window through the free diffusion of Brownian motion.

Third, several common measures to improve indoor PM2.5

After talking about the source of indoor PM2.5, we should choose the right way to improve the indoor environment. It is necessary to solve the problem of ‘open source’, that is, reduce the input of outdoor PM2.5 to the room, and increase the interior of indoor PM2.5. Filter and process. Considering that people’s living habits are hard to change, we mainly analyze the following common measures: improving the airtightness of the outer window, adding new air blowers, and purchasing mobile air purifiers.

1. External window air tightness
Under normal circumstances, the construction engineering standard requires that the airtightness of the outer window should not be lower than the 6th grade specified in GB/T7106, and the corresponding air permeability is 1.5≥q≥1.0 m3/m.h. The unit of this indicator is not difficult to see, this represents the volume of air permeating the length of the outer window per unit length per hour. This is a minimum requirement, but it may often be different due to the quality of the construction or the actual effect of the door and window product process. Considering the severe situation of outdoor PM2.5, doors and windows as the main barrier to block the penetration of outdoor PM2.5 into the room, we should first ensure that the airtightness of doors and windows is maximized, including the selection of good sealing materials, and improve the assembly quality of doors and windows.

2. Home user-type new fan
On the basis of the basic measures to meet the airtightness of the outer door and window, the current active measures are to install a new type of fan or purchase an air filter. The main function of the new air blower unit is to introduce fresh outdoor air into the room, replace the dirty air in the room, improve the oxygen content of the indoor air, and continuously remove harmful gases such as odor and formaldehyde/VOC. However, if it is to remove PM2.5, its effect on improving PM2.5 is not obvious. After calculation, when the outdoor PM2.5 concentration is 200μg/m3 heavily polluted, a 120m2 apartment type house is equipped with a 230m3/h new air blower unit (0.7 gas exchange, meeting national specifications), which takes about 180 minutes. That is, at 3 hours, the indoor PM2.5 concentration reached a stable value of about 60 μg/m3, and did not reach the level of excellent air quality.

3. Mobile air purifier
Since the internal circulation mode of the new wind turbine group has a certain improvement in indoor particulate concentration compared to the fresh air mode. Then consider another measure, using a separate air purifier. In general, we will set up air purifiers in different rooms. Then install a living room (40m2) in the house to install a common CADR of 400m3 / h air volume, air purifier. Within about 30 minutes of using the air purifier, indoor PM2.5 can be reduced to below the national health standard of 35μg/m3. In the end, it can reach the WELL Healthy Building Standard (15μg/m3) and the WHO Air Quality Guidelines (10μg/m3) in an hour or so. It is not difficult to see that the air purifier circulating in a large air volume is very effective in improving the indoor PM2.5 compared with the fresh air system.

How to improve the air quality inside the car in the haze

Driving in the haze, traffic is more congested, and people stay in the car for longer than ever. In a seemingly closed space, the degree of pollution is not worse than the outside, so it is necessary to prevent flooding in the car. Then, in this environment, in addition to paying attention to conventional safety, how do car owners make the air in the car more ‘clean’?

First, close the window, open the inner loop
For many people, there is a car travel, this relatively closed space can avoid contact with the “ten face crouching” to some extent, the car window is closed at the first time when driving on the road. In fact, in addition to closing the window, there is one more step to be aware of, that is, to open the inner loop.

Opening the outer loop is the same as opening the window, so that the air outside the car enters the car. That is to say, the air passage outside the vehicle and the inside of the vehicle is circulated, and the wind blown by the fan comes from outside the vehicle. Even if the fan is not blown, the airflow is still sucked into the vehicle while the vehicle is running, and the fresh air in the vehicle is replenished. Therefore, in foggy weather, even if the doors and windows are closed, high concentrations of suspended pollutants or respirable particulate matter can enter the vehicle through external circulation.

The inner circulation is to close the airflow passage inside and outside the vehicle, forming a circulation of air inside the vehicle, effectively preventing external dust and harmful gases from entering the vehicle, and blocking harmful exhaust gas discharged from the preceding vehicle in a dense area of the vehicle.

Therefore, in the fog, when you drive, you not only need to close the doors and windows, but also try to open the internal circulation system of the air conditioner inside the car. For many models with automatic air conditioning, the vehicle will default to the outer loop when starting, so don’t forget to switch to the inner loop. Of course, if the circulation in a long time will cause the air in the car to not circulate, if it is running at a high speed or in the car for too long, then it will open for a while and let the outside air come in.

Second, regular cleaning and replacement of car air filter
When the smog is heavier, many people will wear masks for themselves. After they have been used, they should be cleaned in time or thrown away. The car actually has a “mask”, that is, the engine’s air intake filter and air conditioning filter. These two items are like the air protection umbrella of a car, which can effectively reduce the entry of pollutants into the car through heating ventilation and air conditioning systems, and prevent the inhalation of harmful pollutants when driving.

However, in the polluted environment for a long time, the engine’s air intake filter and air-conditioning filter will also absorb a lot of impurities and dirt. Too much dirt will deposit on the filter element, which will not only reduce the intake efficiency, but also reduce the engine power and air conditioning. . The dirt accumulated on the filter element will breed bacteria and cause mildew, which will cause air conditioning odor, which not only affects the ride comfort, but also poses a threat to health. Therefore, the engine intake filter of the car should be replaced regularly. At the same time, the air conditioner filter is the first door of the car air conditioner. The air quality of the car is also very large. The air conditioning system should be cleaned regularly and the air filter should be replaced according to the maintenance manual.

Under normal circumstances, change every 15,000 km. Of course, in places where air pollution is more serious, it should be replaced every 10,000 kilometers or less. Generally, 4S shops can operate.

Third, install car air purifier
The car does not have its own air purification system. It can purchase an in-car air purification device. After installation, it can eliminate the odor, toxic and harmful gases, bacteria and viruses in the car.

Fourth, do not smoke in the car
Cigarettes, cigars and pipes produce PM2.5 fine particles in incomplete combustion and are one of the main sources of indoor PM2.5.Many people like to smoke in the car. However, the fog can not open the window to ventilate, smoking is equal to the PM2.5 index in the car, so try not to smoke in the car.
