What is HEPA Air Purifier?

HEPA stands for High-Efficiency Particulate Air, and is a filter type that’s designed to adsorb air contaminants such as pet dander, pollen, tobacco smoke, mold, dust, and dust mites. It’s used extensively to improve indoor air quality, especially for environments that need to be scrubbed of allergens for people suffering from allergies and asthma.

HEPA Filter Definition:

A high-efficiency air filter designed with randomly arranged, fiberglass fibers. Also known as a depth filter, its porous design retains particulates of a specific size (depending on the filter grade), ensuring that they aren’t released back into the environment. Due to the nature of the design, these filters can hold a significant amount of waste before requiring replacement.

High-Efficiency Particulate Air (HEPA) cleaners help scrub indoor air to remove airborne waste. Sometimes these air cleaners combine filtration methods using HEPA in parallel with activated carbon filters, UV lights, and sometimes ionizers to further clean the air.

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.”

The Surprising Benefits of Air Purifiers

Here are several surprising benefits of air purifiers I have noticed after purchasing and using an air purifier/ionizer for the last few years. The best air purifier for you is usually not that hard to find with some basic research.

Pets share our homes every day and bring with them pet odors, urine stains, and skin dander. For family members who have allergies, these odors can be upsetting and cause respiratory distress, which may result in a visit to the hospital with expensive and prolonged treatment.

Vacuuming isn’t enough to remove all these pollutants daily. We all love our domestic animals, but did you know:

• Having a cat in your bed or lounge can result in skin dander being left in the bed linen and the lounge fabric.
• Dogs bring into the home odors and germs from outdoors into the house.

The world’s largest air purifier sucks in smog and turns it into jewellery

The air we breathe is not as clean as it once was – and in many cases, it is getting worse.

According to a recent study by researchers at UC Berkeley, smog kills about 4,000 people every day in China. And in the US about 4 in 10 people live in counties that have unhealthy levels of either ozone or particle pollution, according to the American Lung Association.

To help clean up our air and make it breathable again, Dutch designer Daan Roosegaarde created a 23-foot (7-metre) tall air purifier called the Smog Free Tower.

The tower-like device essentially sucks up smog like a vacuum from the top and then releases the filtered air through its six-sided vents. It can clean more than 30,000 cubic metres of air per hour and runs on 1,400 watts of green energy.

The project, which was funded on Kickstarter, took Roosegaarde about three years of research and development, but he is finally showing off the prototype of his giant air purifier this week in Rotterdam. According to Roosegaarde’s website, the air purifier was specifically created to be used in public parks.

Roosegaarde describes how the tower works on its Kickstarter page:

“By charging the Smog Free Tower with a small positive current, an electrode will send positive ions into the air. These ions will attach themselves to fine dust particles.

A negatively charged surface – the counter electrode – will then draw the positive ions in, together with the fine dust particles. The fine dust that would normally harm us, is collected together with the ions and stored inside of the tower. This technology manages to capture ultra-fine smog particles which regular filter systems fail to do.”

But the well-designed air purifier doesn’t just clean up smog, it can also be used to make fine jewellery.

The fine carbon particles that the tower collects can be condensed to create tiny “gem stones” that can be embedded in jewellery pieces like rings and cufflinks. Each of the tiny stones is the equivalent of 1,000 cubic metres of air.

While the prototype is currently in Rotterdam, Roosegaarde aims to eventually roll out other models in Beijing, Mexico City, Paris, and Los Angeles.

China to deploy the world’s largest outdoor air purifier in Beijing

China will deploy 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. 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.

The tower can capture about 75 percent of PM 2.5 and 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 color-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.

One-quarter of air purifiers fall short of quality standard

One-quarter of air purifiers sold on the domestic market are substandard, an inspection by China’s top quality authority showed.

The inspection, conducted in the first half of this year, found 15 of the 61 batches of products were substandard, according to the General Administration of Quality Supervision, Inspection and Quarantine.

This is the first time that the administration has organized a national quality inspection aimed at air purifiers, and the inspection covered most well-known air purifier brands available in China, said Zhang Wenbing, chief for quality supervision at the administration.

The inspection covered nearly 20 percent of China’s air purifier producers, and of the models by big enterprises, 90 percent were up to standard, much higher than average, according to the administration.

No products by big brands such as Honeywell, Samsung and Midea were found to be substandard.

However, purifiers made by Chinese firms Guangdong Jingba Technology Co. and Shanghai Xinsong Electronics Co. were found to be substandard, due to respective issues of failing to remove methanol and failing noise standards.

“Results of the inspection can provide the basis for consumers to choose air purifiers,” said Song Guangsheng, director of the National Quality Supervision and Inspection Center for Indoor Environment and Environmental Products.

With increasing demand for purifiers in recent years, the number of producers has also risen, but many purifiers on the market may not work as well as advertised, he said.

“Many air purifier brands claim to be able to remove methanol, but in fact, few of them are able to do so,” Song said.

In the first half of the year, 4.5 million air purifiers were sold in China, 58 percent more than the same period last year, according to media reports.

Zhang Xiao, an inspector at the National Quality Inspection Center for Household Electrical Appliances, said China has strict quality standards for air purifiers, and some key indexes include noise level, capacity to remove pollutants and purifiers’ toxic emissions.

‘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.

Olans air purifier OLS-K04 1

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.
