Olan Air Purifier OLS-K04 1

The Harvard Youth Innovation Challenge is understood as the Harvard China Education Forum, which aims to build an exhibition platform for young people. From the point of view of the organizing committee, the former Harvard China Education Forum, as an educator, has reached a peak of dialogue in China and has nothing to do with student education. This new challenge has effectively attracted students to participate in the Harvard Chinese Education Forum and to connect with Chinese people to test their creativity and public relations observation skills.

Beijing Royal School won the first prize in the competition brought to you by DIY’s own low-cost air purifier exhibition, which was unanimously affirmed by educational experts. In the start-up process, urban students with increasingly serious environmental pollution have analyzed the causes of air pollution and jointly developed air purifiers with low cost, high efficiency, simple manufacturing, and low cost.

With Airpocalypse attacking the Chinese crowd air purifier Market

With Airpocalypse attacking the Chinese crowd air purifier Market

At the beginning of Christopher Nolan’s new work Interstellar, the Earth became a livable dustbowl filled with air, suffocating the lungs. The horrible anti-utopia depicted in the film may cause anxiety in the Chinese people. It is very similar to what we are experiencing now.

The deterioration of air quality has led to a surge in sales of air purifiers because people are eager to protect themselves from smog. According to the Research Institute AVC, the market size of air purifiers is expected to exceed RMB 12 billion yuan (about US$1.93 billion) in 2013, RMB 20 billion yuan in 2014 and over 750 billion yuan in 2015.

The fast-growing market has attracted many companies. According to another AVC report, the number of domestic air filter manufacturers surged from 21 companies in the first quarter of 2014 to 95% in the third quarter of this year.

Establish your own air purifier

Establish your own air purifier

In the air purifier market? Given the winter’s attempt to close the area in China, maybe (hopefully) you’ll buy a jacket that won’t warm? This is not the case. The market for air purifiers that cannot provide clean air is exploding and easily lost.

Well, I know what the logic is: so Blueair 403 will be 66% clean because I have Blueair 603 in my living room, which is 66% less in most cases. Yes, the dirt is dirty, as dirty water, the purifier is too small, and the room may do nothing. It was really uncomfortable or at risk of disease on those days when the pollution was serious.

HEPA is a kind of material used to manufacture air filters. The design and manufacture of HEPA air purifiers are closely related to its performance. Turn on the machine immediately, observe the filter carefully, size, structure quality, weight and make sure you understand your own things.

Do you know you want to buy a new air purifier? Make sure sales representatives are busy getting extra filtering benefits. After filling and exposing filters to the world’s worst pollution for months, they are one that deserves death.

Beijing plans to install air purifiers

Beijing plans to install air purifiers

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. Under this, all urban kindergartens, primary schools, and high schools are closed.

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.

Household Air Purifier: Risk of Stroke Caused by Poor Air Quality

Household Air Purifier: Risk of Stroke Caused by Poor Air Quality

A new study in Germany shows that particulate matter has recently been linked because quality accurately indicates the adverse effects of smoke and air pollution on our respiratory system. The level of stroke in adults has risen.

More than 4,400 residents of Bohong, Essen and Milheim Anders completed the survey. Participants were selected between 2000 and 2003, aged between 45 and 74. In addition, the authors assessed the particulate matter and noise exposure based on the participants’residence.

The results show that with the increase in air pollution, stroke may occur. The results of coronary artery events are not clear, and the effect of exposure to noise pollution is not obvious. Cardiovascular diseases caused by particulate matter exposure

Olansi, Guangzhou, is well aware of the harmful effects of air pollutants, especially particulate matter, on health.

In order to reduce the negative impact of exposure to insufficient air quality, we are conducting extensive research on high-end filtration, so as to provide buyers with the best air freshener filter in the world.

Our doctor-approved home air purifier provides a true HEPA filter that removes 99.97% of the smallest particles from the air – the most harmful particles with a limit of more than 0.3 microns, while some competitors can only remove less harmful particles.

If you live in a place with poor air quality or frequent allergens in the air, consider using a doctor-approved Olansi air purifier and avoiding stroke or other health problems for you or your family.

Which schools in Beijing are studying air pollution?

Which schools in Beijing are studying air pollution?

The most serious level of air pollution recorded so far in Beijing has led to a rapid increase in sales, concerns about healthy air purifiers, and in many international schools around Beijing, procedures have been reassessed when AQI is soaring. Beijing International School 7 is to answer your pollution protection measures and students’health problems.

Air pollution measures are common causes, but when the ceiling has been established and any outdoor activities are canceled, the ceiling depends on the school. Staff will have to keep an eye on the US Embassy and the Chinese government. Schools have not yet set a ceiling on indoor activities to publish air quality measurements and monitor indoor air quality in most households.

Harrow is the principal nurse of Beijing International School, NICI Newbold, who monitors AQI and provides guidance for school pollution control measures. Like many other schools in Beijing, schools will use the 275 AQI deadline to cancel all outdoor activities. “275 is a random number, but [schools] are trying to find a balance between students who are against aggressive pollution risks,” said Newbold. In the case of Saturday sports, rake, according to the criteria already stipulated by the International School Track and Field Championship (ISAC). If 251 events that had been in AQI for more than three hours or had become events, the event would have been canceled. The event will be canceled when the air quality index reaches 276 at the beginning of the competition.

Newbold said that when asked if “sudden fantasy” caused higher respiratory problems, “the school showed a higher incidence of certain, this week, many students and staff from upper respiratory tract infections he answered.” At the beginning of the school year, student Haro’s air quality, and open a meeting about what this level means to you, and what to do.

Many international schools invest in personal classroom air purifiers. At Beijing International Montessori School (MSB), the air filter in the classroom is always on and has been replaced regularly. In addition, MSB strictly abides by the pollution control policy. Bevenhoffman said MSB systems and library management were “dangerous” levels for which “safety” levels were likely to change very quickly, and the school explained, “Check pollution levels.” When the US Embassy reported more than 200 AQI, all students had to stay in the building. If all outdoor activities stop, students start knitting for activities such as reading libraries.

Beijing Canadian International School (CISB) is also suitable for all classes.

In other schools, whether it is air quality, to ensure that students can participate in physical exercise, which requires a lot of money. Regardless of Dewey Beijing, Beijing International School (ISB) is that you have made a dome, especially for sports. The dome is pressurized and has a built-in filtering system. ISB recently completed the construction of two domes. The material was shipped from the United States.

Dewey’s dome was completed in September 2011, and in the summer of 2012, we built an air purification unit in our school. In AQI, measurements within the dome usually range from 0 to 5. According to Dewey, they worked with ISB and Beijing Jingxi School (WAB) to sample air quality on campus and were asked to participate in a research project, which was compared with official government statistics. To this end, Dewey plans to install scanners in its Lenovo Garden Park.

Asthma Air Purifier

Asthma Air Purifier

Avoid spring allergens to reduce asthma symptoms

Allergic diseases such as allergic asthma affect more than 20% of the population and are the sixth leading cause of chronic diseases in the United States.

Muscles in the bronchial wall tighten, producing excessive mucus, narrowing the airway, causing frequent and frequent coughing, leading to mild and severe dyspnea. In some cases, breathing can be laborious, leading to life-threatening asthma attacks.

“Allergic asthma is the most common form of asthma,” said Dr. Sheldon L. Specter of FAAAAI and the chairman of the AAAI Asthma Diagnostic Committee. “As symptoms get worse, asthma is considered an allergy. Individuals are exposed to sensitive immune system allergens.

About 60% of asthma attacks are caused by allergens, such as wildfires, smoke and animal dander, but other allergens (such as mites, fungi, cockroaches, etc.) can also cause reactions.

Tips for reducing primary allergies:

Be careful with ozone alerts. These alerts give you an idea of the potential triggers for the day.

Minimize outdoor activities on overheated days.

Don’t take more drugs to relieve severe symptoms without consulting a doctor.

Use an air purifier at home to keep indoor air clean.

Don’t park directly above the car you’re driving, because exhaust gas can cause asthma attacks.

Air Purification Tower Comes to Beijing

Air Purification Tower Comes to Beijing

The world’s largest air purifier takes over China’s smoke. The Smoke Freedom Tower arrived in China in September and created clean bubbles in downtown parks, including Beijing and Rosgard. Please raise awareness of the dangers.

When artist Daan Roosegaarde visited Beijing in 2014, his inspiration came from something he had never seen before.

From his hotel room on the 32nd floor, his views on a large number of Chinese capitals were completely obscured by smoke.

“Everything’s gone,” Rosegard said.

Two years later, he was visiting China on the world’s largest air purifier.

Smoke Freedom Tower produces clean bubbles in city parks, and Rosgard hopes to raise awareness of the dangers of air pollution.

Rabbits also like beautiful air.

The tower has just been commissioned in Rotterdam, Rosgard’s home town, and its company Studio Roosegard is headquartered in Rotterdam.

It has had an amazing impact on the local environment.

“For some reason, the rabbit was particularly interested in the space around the tower. I don’t know why. Maybe they can feel the difference, “he said.

Using ion technology, the tower attracts small capture particles (PM2.5 and PM10) to capture and release clean air. Roosegaarde says it leaves about 75% of the clean air.

“Basically, it has a plastic balloon with static electricity, with static electricity, and it attracts hair when brushing by hand.”

Roosegaarde said that a seven-meter tall tower can purify about 30,000 cubic meters of air per hour. “It’s a small area.” Its power is only 1,400 watts.

Can these towers save lives?

The tower is scheduled to arrive in Beijing and China in September.

The trip is a collaboration between Studio Roosegaarde and the Ministry of Environmental Protection of China, which will determine China’s urban sites based on the results of a public vote.

After China, Roosegaarde plans to take the tower to all parts of the world – Mexico City and India are under consideration.

More than 80% of the urban population is exposed to air quality levels that exceed the World Health Organization limits, and as urban air quality declines, the risk of stroke, heart disease, lung cancer, asthma, and other diseases decreases. It rises.

Outdoor air purifier reduces your waiting by 40% smoke

Outdoor air purifier reduces your waiting by 40% smoke

According to the Ministry of Environment, China’s campaign to clean up air pollution last year has reduced the level of dangerous particulate matter in the atmosphere by 11%, but there is still a long way to go before the public breathes air every day. Of the 74 cities surveyed, only 8 met basic domestic air quality standards.

Meanwhile, antifouling masks are a popular project, and start-ups that produce new indoor air purifiers are lowering prices. New inventions currently being tested in Hong Kong are causing an average of 40% of outdoor air pollution claims to be reduced (h/t to Techweb).

In the patent-pending prototype system, air is sucked into the system from the bottom entrance, then circulated through a bag filter to remove fine suspended particles (PM10 and PM2.5) which effectively come out of the Louvre’s head.

Hong Kong has been testing at a purification station 2 m 3 m East of Queen’s Avenue in Causeway Bay, one of the best streets since March, at a cost of HK$600,000 per unit of Sino Green’s Asian Science and Technology Building (reportedly US$77.4 billion). In the earlier part of this article, an article on Techweb pointed out that it would cost $10 million to develop the project, but Sino Green explained that the figure was not accurate.)

Further quality improvements include smart controllers for more efficient management of uptime, solar panels for energy and mist cooling systems in summer.

According to Techweb, the urban air purification system will be tested at Tsinghua University in Beijing, and if all goes well, it may extend to other mainland cities in the future.
