Jokes and air purifiers: life of Beijingers in the days of smog

 

As with many of the country’s more solemn situations, the choking smog blanketing Beijing since Monday has evoked such wisecracks from social media users making light of the dire air situation.

In the past few days, jokes on the topic have become one of the most discussed threads on China’s largest microblogging site Sina Weibo.

But despite the light-hearted approach to the pernicious atmosphere, the capital’s residents are feeling the impact of what is the most severe bout of smog in Beijing since July.

The National Meteorological Center (NMC) upgraded Tuesday’s yellow alert to orange, the second highest, on Thursday afternoon. It suggested people stay indoors and wear masks if going out.

Dou Chen returned from the UK to China this February. Since coming home, she has suffered from a nettle rash for five months. A blood test found that she is allergic to substances in the air.

“When I travel outside Beijing, my symptoms are relieved,” she said. But in the past two days, the rash worsened.

In the Guang’anmen Hospital, a doctor told her the symptom were affected by the smog.

An unnamed staff member with the Beijing Children’s Hospital told Xinhua although they haven’t seen an obvious rise of patient numbers yet because the smog just started, they were told to prepare for a peak in respiratory problems.

Wang Xia, 34, is a teacher with the No. 25 Middle School. “Whenever persistent smog occurs, more students ask for sick leave,” she said. “In a class with about 40, once more than 10 students left in the afternoon.”

The environment watchdog in Beijing blamed farmers’ burning fields of straw for causing the smog, an allegation doubted by Beijingers.

But Li Lixin, an air pollution treatment official with the Beijing Environmental Protection Bureau, said a satellite test conducted during the summer of 2013 showed a discharge from widespread straw fires could drive up the PM 2.5 reading in Beijing from 110 to 460 micrograms per cubic meter in a few hours.

Still, web users question the charge.

“Agriculture has been a vital industry in China for hundreds, if not thousands, of years, and it is the tradition in rural areas to burn straw after autumn harvest and plough to bury the ashes in the ground as fertilizer,” said a Weibo user nicknamed Sunflower. “But why we didn’t have smog in the past?”

At such criticism, Wang Yu, head of the energy ecology department of the Beijing Agricultural Bureau, admits pollutants were mainly from motor vehicle exhausts, coal burning, industrial production and dust, rather than burning straw.

“But this is the season for burning straw, coinciding with a special climate which features high humidity and lack of wind,” he said. “It was like the straw that breaks the camel’s back, worsening the air pollution.”

Beijing and its surrounding provinces have banned straw burning. And anti-smog measures didn’t stop there.

In addition to the straw ban, the city pledged to replace coal with cleaner burning energy like electricity and natural gas for domestic use. They also hope to curb coal sales and use by the end of 2020, as well as other high-pollution fuels, such as fuel oil, petroleum coke, combustible waste and some biomass fuel.

Beijing has also raised the discharging fees for major pollutants such as sulphur dioxide and nitrogen oxide this year.

Li Lixin noted that it might take time to see the achievements of such measures, but the government has attached great importance to the issue, and people’s awareness of environmental protection has improved.

In the meantime, Beijingers are avoiding the outdoors and doling out thousands to protect themselves indoors.

An old man surnamed Cheng said his friends with asthma and bronchitis would remind each other not to go out in smoggy days.

Wang Xia’s school has stopped outdoor activities for students. “What if we could have air cleaners installed in each classroom,” she said.

According to a Mr. Zhang, a sales representative of electrical appliance brand SHARP on e-commerce platform JD.com, sales of air purifiers almost doubled in the past two days.

Fu Baoling, a retired worker, just bought a purifier for 2,100 yuan (about 342.6 U.S. dollars). “My granddaughter is young, so I bought this especially for her,” she said. “I don’t know whether this is effective or not. I just hope the sky could clear up soon.”

China To Deploy World’s Biggest Air Purifier In Beijing To Fight Heavy Smog

China will deploy the world’s largest outdoor air purifier designed by a Dutch engineer in its smog-hit capital Beijing, as the thick heavily-polluted haze returned to haunt the city, driving people indoors. The seven-meter-tall tower, brainchild of Dutch designer Daan Roosegaarde, is undergoing last-minute checks in Beijing’s 751 D Park art area.

Biggest Air Purifier

The ‘Smog Free Tower’ will soon be opened to the public, and will be toured across the country, state-run Global Times said, quoting China Forum of Environmental Journalists, an NGO under China’s Ministry of Environmental Protection.

Pollution

The tower can capture about 75 per cent of Particulate Matter 2.5 (PM 2.5) and Particulate Matter 10 (PM 10) tiny particles in its vicinity and then release purified air to create a “bubble” of fresh air around it. The tower can clean 30,000 cubic meters of air per hour through its patented ozone-free ion technology.

Beijing has been plagued with heavy smog since the beginning of October. The city’s environmental authorities issued a “yellow alert” for air pollution on Tuesday. “Yellow alert” is the third-most serious level in a four tier colour-code warning system. Red is the most serious and orange the second-most serious while blue is the least serious pollution level.

The average PM2.5 density of the small deadly polluted particles crossed over 300 today even though a cold front in the morning cleared the smog a bit. Liu Guozheng, CFEJ secretary-general said the tower is intended to warn authorities never to forget their duty and encourage the public to pull together to combat the smog.

The public, meanwhile, are bemused by the tower’s function and have called on authorities to curb dangerous sources of polluting particles, the daily said. Netizens expressed their frustration over the tower.

“The so-called divine smog cleaner is more like a piece of performance art, which makes almost zero difference to cleaner air in the city. It devours the polluted air and exhales fresh air, but so little it won’t make any difference. The air will stay polluted,” the daily quoted a comment by Sina Weibo user.

‘Smog Free Tower’, largest air purifier in Beijing, sparks controversy

A “Smog Free Tower” undergoing tests in Beijing’s famed 798 art zone has sparked controversy amid continuous heavy smog in the last couple of days.

The seven-meter-high metal structure, designed by Dutch artist Daan Roosegaarde and introduced to the Chinese capital as the world’s largest air purifier in late September, opened for testing and adjustment recently.

The tower boasts a capacity to purify 30,000 cubic meters of air per hour and an ability to capture at least 75 percent of PM 2.5 and PM 10 particles, creating a fresh-air area around the tower, China Youth Daily reported.

The designer also said that particles collected by the tower could be processed into black gems.

Some experts questioned the usefulness of the newly-installed air purifying tower. According to calculations by an expert, it can absorb merely 4.5 grams of PM 2.5 an hour on heavy pollution days, which is less than the equivalent of a spoonful of salt, the paper reported.

“It would work better to have the construction site covered by a piece of cloth,” the expert joked.

In other cities, various facilities aimed to combat smog have also been installed. “Perhaps people are desperate about combating smog,” commented He Jijiang of Tsinghua University.

But those smog-treating facilities are only experimental and cannot solve the fundamental problems, He said.

Beijing was again shrouded in smog, with particle concentration in the air continuing to rise from midday on Tuesday, and the heavy pollution had lasted 19 hours as of midday Wednesday.

Six of the capital’s monitoring sites reported heavy pollution, which continued to worsen, prompting the Beijing Meteorological Service to issue a yellow alert for air pollution on Wednesday, the fifth of its kind since the beginning of October.

Understanding the Pros and Cons of DIY Air purifier

Impurities in the air are a concern to anyone who wants to avoid respiratory problems, and installing an air purifier as a do it yourself project is an option worth considering. Given the low cost budget required to set up your own air purifier, this option has emerged as one popular option in many poorer cities where majority of the population find such leading air purifier as IQAir to be way too unaffordable.

Some concerns that you may encounter can delay or derail a project, and anticipating what can go wrong helps you find a way around typical problems. By conducting an air purifier review, you can find the best air purifier for your purposes.

So, should you choose to jump into it and start making your own DIY air purifier? Few considerations are important which you might want to ponder a little more before rushing your decision.

What are those considerations? Read on to learn more.

Pros and Cons of DIY Air Purifier

What Air Purification Power Do You Need?

To get the most effective results from your efforts, you need one that can treat the entire interior of your home or one that is suitable for one room. A system that can clean the air in your whole house may require duct-mounted units or several room air purifiers.

Room units may cover a space as small as 80 square feet or as large as 800. The advantage of using a room air purifier is that the cost for one unit is less than that for treating an entire residence. The disadvantage is that it may not remove as many air particles as one that treats a larger area.

So, knowing what kind of air purification efficiency you need is the first thing you need to ask yourself.

Quality of Your DIY Unit

The poor quality of air in some areas of China is notorious, and it poses serious threats to health. Bloomberg Businessweek recently reported on the efforts of aFulbright scholar to design and build an air purifier for his home.

Living in China for a year led him to investigate the components of air purifiers, and his research led to the development of a simple system. The basic components consisted of a HEPA filter and a fan, and he fashioned a Velcro strap to secure them together.

Testing the effectiveness of his invention required an investment in a monitor, but the results were impressive. By strapping the filter to the flat surface of an ordinary fan, he reduced PM.05 levels indoors by nearly 85 percent. Levels of PM 2.5 indoors fell by more than 90 percent.

From the picture and demonstration, constructing your own DIY air purifier appears like such a simple thing. But getting down right to do it yourself is another thing which might be more challenging that it seems.

One thing you want to keep in mind is the quality of your fan. Some fans are more powerful than others and they run on better quality motor. Think about it. How long do you think your fan will last if you have to turn it on 24×7? Does it have enough power to deliver the kind of CADR rate that top-rated air purifiers for smoke removalin the likes of Rabbit Air MinusA2 is able to deliver?

Outdoor Air Purifier Makes Your Wait for the Bus 40% Less Smoggy

China’s campaign to wipe out air pollution reduced the levels of dangerous particulate matter in the air by 11 percent last year, according to the Ministry of Environment. But the country still has a long way to go before the air its citizens breathe every day can be considered healthy. Only eight out of the 74 cities surveyed met basic national air quality standards.

In the meantime, public awareness is rising. Pollution masks are hot commodities and startups making new models for indoor air purifiers are driving prices down. Now, a new invention currently being tested in Hong Kong claims it can reduce air pollution in an open outdoor space by an average of 40 percent (h/t to Techweb).

Under the prototype of the patent-pending system, air is drawn into the system from the inlet located at bottom. The air current then passes through a bag filter, which is effective in removing fine suspended particles (PM10 and PM2.5), before coming out through the Louvre overhead.

Hong Kong has been testing 2 meter-by-3 meter purification station on one of its busiest streets, queen’s Road East in Causeway Bay, since March. Sino Green tells Tech in Asia one unit costs HKD 600,000 (US$77,400 million). (Update: an earlier version of this story referenced the Techweb article that said the project cost US$10 million to develop. Sino Green has informed us that figure is not accurate.)

Air quality at the station can be monitored remotely. Further planned enhancements include smart controllers to manage operating hours more efficiently, solar panels for energy, and a mist cooling system for summer months.

Techweb says the City Air Purification System will be tested at Beijing’s Tsinghua University next. If all goes as expected, it could expand to other mainland cities in the future.

What to Look for When Shopping for an Air Purifier

A lot of people worry about the air they breathe. With all of the cars on the road and factories spewing out toxins, air pollution is pretty bad. What a lot of people don’t realize is that indoor air pollution can be even worse than the pollution outside.

Indoors we have to deal with things like dust, pet dander, mold spores, pollen, volatile organic compounds, fumes from cleaning products and other household chemicals, the list goes on and on. Some of the things floating around in the air inside your home can trigger allergic reactions, and some things can actually make you very sick.
