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.

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.

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.

Beijing to get largest air purifier

To the bafflement of some local residents, the world’s largest outdoor air purifier arrived in Beijing to help the capital combat its persistent hazardous smog.

The brainchild of Dutch designer Daan Roosegaarde, the tower is  undergoing last -minute checks in Beijing’s 751 D Park art area. The public, meanwhile, are bemused by the tower’s function and have called on authorities to curb dangerous sources of polluting particles.

The Smog Free Tower will soon be opened to the public, and will be toured across the country, the Legal Daily reported, quoting China Forum of Environmental Journalists, an NGO under China’s Ministry of Environmental Protection.

New standards set for air purifiers

A new national standard for air purifiers was unveiled by authorities on Friday to bring order to the country’s chaotic purifier market.

The draft national standard, which is also made available for public comment on Friday, will include more specific metrics for measuring the performance of air purifiers, including their “clean air delivery rate” and endurance, China daily reported on Saturday.

The country’s widespread air pollution problem has given rise to a booming market in air purifiers, with total sales volume reaching 2.4 million units in 2013, the report said.

ae6c82e48c947a81d419c76e95788e40

However, the market is chaotic with many producers and sellers of air purifiers exaggerating the performance of products and deliberately misleading consumers during promotions, the report said, citing the Beijing Municipal Bureau of Industry and Commerce.

According to a spot check on 20 air purifiers by the Shanghai Bureau of Quality and Technical Supervision in December, only the products of three companies reached their advertised effectiveness or indicated the space in which they would function effectively, according to the report.

The new draft proposes detailed requirements for the labeling of air purifiers. Producers must mark clearly on the product label both the service life and the volume of space for which it can provide effective filtering.

The draft standard includes performance data for both particles and formaldehyde.

The national standard on air purifiers, enacted in 2002 and last revised in 2008, has failed to keep up with the expectations of the public, the report said, citing Song Guangsheng, director of the National Indoor Environment and Indoor Environmental Product Quality Supervision Center.

“The previous national standard on indoor air cleaners did not take into consideration the need for consumers to filter PM2.5 or increased frequency of use,” he said.

PM2.5, particles under 2.5 microns in diameter, is a key indicator of air pollution in China. High density of PM2.5 has also become a major cause to smoggy air conditions that plague many regions in the country in recent years.

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?
