‘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.

Static Electricity: A Spark of Interest

We’ve all have experienced static electricity in one way or another. Those unexpected little shocks we get when we touch a doorknob or some other metallic object, the balloons that stick to the wall after being rubbed in the head, or hair itself standing straight when it comes close, all are produced by static electricity. Most of the time it is produced when two objects come in contact or are rubbed together.

What is Static Electricity?

All materials are made up of molecules, and all molecules have tiny atoms, with positively charged protons, neutral neutrons, and negatively charged electrons. Most of the time an atom is neutral with the same number of protons and electrons. When an atom’s proton and electron numbers are uneven, the electron dance begins. If you place two different materials next to each other, electrons will start jumping from one material to the other.

Static electricity is generated when any material gains or loses electrons and becomes positively (when it loses electrons) or negatively charged (when it gains electrons). The accumulated charges are what’s called static electricity. Conductive materials like metals and carbon hold onto their electrons tightly, whereas insulating materials, such as plastic, can be charged by friction because they easily gain or lose electrons.

In 600 BC, the Greek philosopher Thales[1] observed that some combinations of materials have more potential to make sparks fly than others. Materials can be catalogued in order of their tendency to become charged, from positive to negative. The lower an item sits on the list, the more likely it will attract more electrons and become negatively charged. Rubbing objects far from each other on the list creates a bigger charge than objects closer together. For example, polishing a glass plate with a silk scarf electrifies the scarf so that it acts like a magnet.

When you stride across a wool carpet in leather shoes, your shoes pick up extra electrons from the carpet with each step. By the time you lift your foot up off the ground, the electrons will have spread around your entire body, giving you a negative charge. The next time you put your foot on the carpet, your shoe doesn’t have any extra electrons, but your head might. So more electrons make the leap to your foot.

“As you keep walking across the floor, you become full of electrons,” said Todd Hubing, from the Electromagnetic Compatibility Laboratory at the University of Missouri-Rolla. “Eventually more electrons don’t want to come up on you because you’re so charged up. You end up with a high voltage, about 20,000 to 25,000 volts.” That’s serious power at your fingertips, considering a normal electrical outlet on the wall is only around 100 volts[2] of electricity.

Practical Uses of Static Charges

Dust removal: There are some appliances that can eliminate dust from the air, like air purifiers. They use static electricity to alter the charges in the dust particles so that they stick to a filter of the purifier that has an opposite charge as that of the dust (opposite charges attract each other). This effect is also used in industrial smokestacks to reduce the pollution that they generate. The effect is basically the same as the home air purifier.95g58picmfk_1024.

Photocopy: Copy machines use static electricity to make ink get attracted to the areas where we need the information copied. It uses the charges to apply the ink only in the areas where the paper to be copied is darker (usually this means text or other information) and not where the paper is white, this process is called xerography.

Car painting: To make sure a car’s paint is uniform and that it will resist the high speeds and weather to protect the car’s metal interior, it is applied with a static charge. The metal body of the car is submerged in a substance that charges it positively, and the paint is charged negatively.

This process ensures a uniform layer of paint, since when there is enough negative paint in the car the extra will be repelled by the paint already in the car. It also ensures that the paint won’t fall off.

Air Purifier Bike

Recently, a website published 2013 annual consumption China keywords. Among them, the “haze” on the list. The data show that the national Amoy friends against the haze of a spent 870 million yuan. Masks, air purifiers, indoor treadmills and other goods were bought 4 million 500 thousand times. The haze from the north to the south of the way that the diffusion. One weekend I call Shenzhen buddy ride together, he was relentlessly rejected — recently is haze, I got respiratory uncomfortable, you don’t go out for it.

This is ironic, sports has become unhealthy things. In my anguish, this Air-Purifier bike comforting my heart. The front is equipped with an electric air purifier, air purifier riding, by inhalation, the pollutants (including dust particles) can be filtered. Out, is the filtered clean air. If you think this is all that is completely mistaken, Air-Purifier bike has a “photosynthesis bike” alias, tripod body through the photoelectric effect to convert sunlight to electricity, start the operation of the fuel cell body, thereby generating oxygen even. When not in use, it is also capable of air purifier and oxygen production machine.

However, want to see Air-Purifier bike and Mami difficult, because it is still in the conceptual stage.Air purifier bike creative director also admitted it, there are still a lot of unknowns, they have only one kind of model, but they will make a prototype to prove the feasibility of this idea. With it German red dot design award, who can say that dreams come true one day be far behind?

Beijing to have world’s biggest air purifier to fight smog

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 per cent 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 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.

Allergy & asthma tips for the holidays

The holiday season holds several potential triggers for allergy and asthma sufferers. Whether it’s setting up your Christmas tree, visiting your pet-owning relatives, or feasting on holiday treats, allergy triggers may be lurking around every corner.

“With hectic schedules and constant traveling around the holidays, it’s easy to forget to take proper care when dealing with allergies and asthma,” said Wanda Phipatanakul, MD, MS, FAAAAI, vice-chair of the AAAAI’s Indoor Allergen Committee. “Remembering to take medication and avoid potential triggers is necessary to keep symptoms under control.”

Tips for an Allergy-Free Holiday Season

Before decorating a live Christmas tree, allow it to dry out on an enclosed porch or garage. You also may want to explore whether the tree retailer has a shaking machine, which will physically remove some allergens from the tree.

  • Clean artificial Christmas trees outside before decorating. They can gather mold and dust in storage.
  • Change the filter in your air purifier.
  • Wash fabric decorations in hot, soapy water before displaying.
  • Use plastic, metal or glass decorations that cannot trap dust mites.
  • When spraying artificial snow on windows or other surfaces, be sure to follow directions. These sprays can irritate your lungs if you inhale them.
  • If visiting relatives’ homes who have pets, take medication before arriving to minimize a possible reaction.
  • The holidays can be a very stressful time of year. Pay attention to your stress level, which can sometimes lead to an asthma attack.
  • Ask your relatives and friends to avoid burning wood in the fireplace. The smoke can trigger an asthma attack.
  • Dust mites can be especially troubling when traveling away from home, take a desktop air purifier and your own pillow with an allergen-proof cover and request down-free pillows if staying in a hotel.

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?

Fighting Childhood Asthma with an Air Purifier

Fighting Childhood Asthma with an Air Purifier

Early detection is the first step in fighting childhood asthma

Does your child experience shortness of breath or irregular breathing? Do you notice a whistling sound when he or she exhales? Does your child have a persistent cough? If so, there is a good chance he or she may be developing asthma, one of the most serious chronic diseases in children and adolescents, affecting nearly nine million children under the age of 18.

According to the American Academy of Allergy, Asthma & Immunology (AAAAI), 50-80% of asthmatics develop symptoms before the age of five. This is why early detection and working with your child’s asthma specialist is important. Untreated asthma can lead to permanent damage to the airways making it difficult to bring the condition under control.

“Children whose immune systems are not fully developed are most at risk for developing asthma,” said Christopher C. Randolph, MD, FAAAI, and Vice-Chair of the AAAAI’s Asthma Diagnosis and Treatment Interest Section. “However, with early detection, the disease is easier to bring under control, improving the quality of life for your child.”

Look, Listen & Learn

There are no clear markers to predict who will develop asthma and who won’t. However, there are clues and symptoms you can look and listen for in your child that may indicate asthma. Ask yourself these questions:

  • Does your child have allergies? The relationship between asthma and allergies is very strong. If your child has allergies, be on the look out for potential signs of childhood asthma.
  • Does your child cough or clear his/her throat often, even when they aren’t sick? This could be constant or just intermittent. Not all children who have the disease exhibit symptoms each and every day.
  • Does he/she wheeze or is there a whistling sound when your child exhales or with upper respiratory infections?
  • Do you notice shortness of breath, rapid or irregular breathing in your child?
  • Does your child complain of chest tightness? A young child may say his/her chest “hurts” or “feels funny.”
  • Does your child seem fatigued? A child might slow down, stop playing or become easily irritated.
  • Does your child have problems sleeping because of nighttime coughing or difficulty breathing?
  • Is there a family history of asthma and/or allergies?

If you answered “yes” to any of these questions and you suspect that your child has asthma, schedule an appointment with an asthma specialist, such as an allergist/immunologist, a physician specially trained to manage and treat asthma and allergies. An allergist/immunologist will work closely with you to create a daily management plan for your child, demonstrate proper medication use, and develop an asthma action plan, which outlines the actions to take if your child’s condition worsens.

Learn

While there is no cure for asthma, complete control of the disease can be obtained with appropriate management and treatment. Learning your child’s asthma triggers and what steps to take to decrease symptoms is an important step to keep your child’s asthma under control. Children whose asthma is properly controlled should be able to participate in regular activities such as attending school every day and playing sports.

 

Beijing plans to make the installation of air purifiers

Beijing plans to make the installation of air purifiers part of its school construction standards to tackle frequent smoggy weather in the capital, local education authorities said Thursday.

Several government departments, including the Beijing Municipal Commission of Education (BMCE), are working to draft the city’s school construction standards, which will include the installation of air purifiers, said BMCE director Xian Lianping, the Beijing Times reported Thursday.

In response to forecasts of heavy smog, Beijing issued two pollution red alerts this winter, under which all the city’s kindergartens, primary and high schools were shut down.

Xian said that the effectiveness of air purifiers in densely packed classrooms has yet to be determined, adding that it is acceptable for schools to independently install air purifiers.

“Installing purifiers in classrooms should ensure students’ safety and should also require parents’ approval,” Xian was quoted as saying.

Parents beset by hazardous smog in Beijing have repeatedly called for primary and high schools to install air purifiers in classrooms, but they have been turned down by schools saying they need approval from education authorities. Some parents even came up with plans to crowdfund air purifiers for their children’s schools, but their efforts were refused.

A small number of some well-funded kindergartens and primary schools have already installed air purification equipment in classrooms, but many more schools cannot afford it due to insufficient budgets.

Hao Xianjun, director of the Shijingshan district’s education commission, told the Beijing Times that schools would turn on their air purification systems on heavily polluted days to lower the concentration of PM2.5 – airborne particles less than 2.5 micrometers in diameter – to below 100 micrograms per cubic meter. Shijingshan Experimental Junior High School will be the first to install such a system when it constructs its new teaching building this year.

During the ongoing fourth session of the 12th Beijing Municipal Committee of the Chinese People’s Political Consultative Conference, many advisors submitted proposals to help schools deal with smog.

Pu Zhe, a member of the committee, said that education authorities should establish a special smog fund to install air purification systems in schools, introduce local regulations on which type of air purifiers to install and launch a unified purchasing platform, the Beijing Times reported.

At Thursday’s session, Xian told committee members that primary and high schools are expected to extend winter vacations and reduce summer vacations, as smog shrouds the capital more frequently in winter, Beijing-based The Mirror newspaper reported on Thursday. Currently, the winter vacation for primary and high schools in Beijing is about one month long.

Build Your Own Air Purifier

In the market for an air purifier? Well, given the winter we are about to close out here in China, you probably (hopefully) are. Would you buy a jacket that doesn’t keep you warm? I hope not, so don’t buy an air purifier that can’t provide you with clean air. The market for air purifiers is exploding and it’s easy to get lost. Stick with us, and we’ll set things straight.

Ok, I know how the logic goes: so a Blueair 403 will clean 66% as well as a blueair 603 in my living room, and 66% less on most days, is ok, right? Pollution is grimy, like dirty water, and needs to move to be cleaned. A purifier that is too small for a room might do next to nothing. On those bad pollution days, this can really put you at risk of discomfort or illness.

HEPA is a fabric-like material that is used in the construction of air filters. The design and production of the filter itself has a lot to do with its performance. Next time you buy an air purifier, make sure you get to take a look at it. Show you know your stuff by immediately popping the machine open and taking a good hard look at the filter, size, quality of construction, weight. Heavy is good.

You know what I love about buying a new air purifier? Hustling the sales reps for deals on extra filters. Remember, you’re not buying an air purifier to be trendy, you’re buying an air purifier because you want clean, fresh air. Once filters fill up and have been exposed to the world’s toughest pollution for months on end, they kind of, well, die. Buy a least a year’s worth right off the bat, so fresh air is never at the bottom of your to do list.
