A new national standard for air purifiers is set to be unveiled by authorities on Friday to bring order to the country's chaotic purifier market. The draft national standard, which will be made available for public comment, will include more specific metrics for measuring the performance of air purifiers, including their "clean air delivery rate", or the number of cubic units of air per minute delivered with all particles of a given size removed, the Standardization Administration said in a statement on Thursday. 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, Nanfang Daily reported. However, the Beijing Municipal Bureau of Industry and Commerce said in a report on Oct 29 that the market is chaotic, with many producers and sellers of air purifiers exaggerating the performance of products and deliberately misleading consumers during promotions. The draft of the new standards also includes indexes that evaluate the service life of purifiers.

In addition, it 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, it said.dental office air purifier The draft standard includes performance data for both particles and formaldehyde.uv light air purifier safe 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, said Song Guangsheng, director of the National Indoor Environment and Indoor Environmental Product Quality Supervision Center.best air purifier for odors reviews "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.

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. Many producers also failed to keep the country's overall air pollution situation in mind, a technician at a Shanghai manufacturer said, providing only his surname, Shen. "Some producers are blindly borrowing the technology of producers in other countries and simply ignore the air pollution situation in China," Shen said.Set as Home Page  | Air Purifier with Heater Air Purifier with Humidifier News about Baren’s 114TH Canton Fair 113th Canton Fair Booth No.: Hall 2.2,M21 112 Session Canton Fair in Oct.2012 2012 Baren Team Success Travel 111th Canton Fair,we achieved complete success Type: Commercial air purifier Intro: Voltage supply: 220V...

The performance far exceeds the original cabin filters., China’s rapid growth, a 30-fold increase in GDP since the late 1970s, has come with the severe side effect of air pollution.

Although a movement to draw attention to poisonous air quality has been growing almost as fast as the country’s cityscapes, solutions have been uninventive and surprisingly slow.When I arrived at Peking University to study air quality in 2013, Beijing had reversed its stance on reporting air pollution. The central government had launched its own monitoring system, and in September of that year published an “Air Pollution Action Plan” that not only limited the use of coal to 65 percent of the country’s energy mix, but encouraged the installation of much-needed air-treatment equipment in industrial plants.With government recognition of environmental problems, individuals and NGOs have increased their advocacy. Earlier this year, journalist Chai Jing gave a talk entitled “Under the Dome,” which received over 150 million views within three days of its release online. While the talk has since been taken offline by the Chinese government, its impact has been compared to Al Gore’s “An Inconvenient Truth” and Rachel Carson’s Silent Spring.

For the first time, all aspects of China’s air pollution—from health effects to industrial noncompliance—were presented in a single comprehensive and accessible presentation.Have these kinds of government and citizen initiatives made a difference? Beijing’s air quality data from the first half of 2015 indicates that the concentration of particulate matter up to 2.5 micrometers in diameter (PM2.5, a measure of air pollution) has decreased to 80 percent of the average in early 2014. And the number of days considered “heavily polluted” has dropped by 50 percent since December 2014. There is evidence, however, that although Beijing’s pollution has lifted slightly, damage from the dirtiest industries is moving to western and southern China. Provinces in those regions such as Henan, Hubei, Hunan and Sichuan are now considered the most polluted of the country. Even for provinces whose data indicate improved air quality, there are legitimate concerns that local governments are fabricating data in order to meet standards.

Given China’s air pollution problems, I wondered why air filters aren’t a household item. The answer is simple: even the cheapest air purifiers cost over a month’s rent.The Beijing residents whom I met were surprisingly inactive in protecting themselves. My lab mates and professors at Peking University, among the leading experts in China’s air quality, never wore the Darth Vader-like masks that keep out 99 percent of PM2.5. (I wore the mask religiously.) Even when PM2.5 concentrations skyrocketed above the accurate detection limit, which is one level above “hazardous,” lab workers kept windows open to the toxic air. I often asked my colleagues why all this nonchalance about the very chemicals they study every day. Their answer was usually some version of Why bother?In the absence of successful governmental intervention, Chinese citizens are literally living in a cloud of pollution. But there is no reason we cannot create short-term solutions. Scientists should be funded to design affordable air filters and user-friendly masks. 

There are opportunities for students as well: courses and grants focusing on international development and product design are flourishing in universities across the country. For example, at the Blum Center for Developing Economies at the University of California, Berkeley, where I attend, courses like Design for Sustainable Communities and competitions like Big Ideas @ Berkeley are pushing students to develop usable and affordable air pollution protection measures.Advances have already been made toward a more affordable air filter. The Smart Air filters developed by Thomas Talhelm, a former Fulbright researcher in Beijing, cost only $33 but they provide the same level of protection from PM2.5 as high-end filters. The design, which consists of a high-efficiency particulate arrestance (HEPA) filter strapped to a fan, is a great way to improve indoor air at an affordable price. Yet these filters are not perfect. They target only PM2.5, while allowing harmful volatile organic compounds (VOCs) such as formaldehyde and benzenes to pass by.

In addition, aesthetic qualities such as low noise during operation, a light indicator to signal when air pollution has reached a safe threshold and an attractive outer shell are missing from these early designs.To date, there are no affordable alternatives to high-end filters that can eliminate not only particulates, but also trickier gaseous compounds. While PM2.5 is generally considered the greatest air quality health risk to the Chinese population, VOCs emitted from sources such as plywood, fabrics, insulation, personal care products and tobacco smoke are also significant indoor air pollutants. A large market exists for a quiet, affordable and attractive filter that targets all components in air pollution. That means that the time is now for scientists and students to design a smart and affordable air filter to address the needs of millions of Chinese consumers.Ming Zhang is a graduate student in Civil and Environmental Engineering at the University of California, Berkeley.
