In this context, broad group an article about their own air purification machine fire. In promoting its air purifiers, the material specifically emphasized that many senior officials work and live in places equipped with their equipment.

The article, called the south China sea in the success story of the great air purifier, which used to be a ubiquitous online advertisement, is barely visible.

" special air"

The original article on yuanda's official blog and the website of its branch describes in sensational style that yuanda purifiers are placed in Zhongnanhai, hidden by the red wall.

Zhongnanhai is the office of an important leader of the state. everything should be absolutely safe: non - toxic, no peculiar smell, no noise and so on. the testing requirements are very strict. But the results are certainly predictable for long-range purifiers that have been certified by a number of national and international standards. ”

The author is proud to write: " more and more state organs, government agencies take the initiative to contact to buy," news broadcast " and other reports can often see the figure of the great purification machine ... when the great purification machine with leadership to visit countries, each great people feel the enormous pride and encouragement in my heart. ”

At the end, the report also listed three important significance of purification machine into Zhongnanhai: " 1. Great purification machine for national leaders to create a healthy and fresh office environment, is the blessing of the people. 2. The use of yuanda purification machine in Zhongnanhai, become the national leaders designated purification machine is a great affirmation and promotion of products. 3. The application of yuanda purifier in the central government department is a great support and promotion to the new life concept of respiratory health and environmental protection. ”

In order to prove that has been settled in Zhongnanhai authenticity, they also specially in the news broadcast officials in Zhongnanhai captured the picture of the meeting, will reveal the air purification machine on the little red circle.

The appearance of this article, caused the people who have struggled in the haze air for days storm-like criticism. Combined with all kinds of " special supply" phenomenon, the term " special supply air" was born.

Celebrity effect

The group did not respond positively to the online criticism except to delete the promotional material.

But employees privately feel some wrong. " this material is not recently written, come out for a year or two. " one man, who declined to be named, complained that it was only because everyone was concerned about air quality and the content of the advertisement was flipped out that everyone felt this way.

The ambitious worker argued that their products were used in many offices and homes in addition to Zhongnanhai, and that their purifiers did well, winning many awards at home. As for advertising using Zhongnanhai, he said it was not the practice of one of their companies. But this is not allowed at this time.

But he also can't explain why advertising " for broad purification machine Beijing branch Guo bin general manager, Zhongnanhai revealed in addition to endless mystery, there is a strong appeal. With great love and confidence of great purification machine, Guo zongyi ran with great purification machine into the red wall " revealed a message, is that they can go into the red wall, general manager of Beijing branch sales.

Far - reaching publicity materials are not just about Zhongnanhai, but also about photos of senior officials and celebrities on its official website. These photos, is divided into " leadership care" and " foreign leadership care".

Long Yongtu is the most frequent person. For example, in a 63 - minute video of a far-reaching air health forum, Long Yongtu, Ren Zhiqiang, pan Shiyi and Wang Ziwen, the president of the gemma club, all have a far-reaching air purifier in front of them, Kan Kan said.

Talk a lot, Long Yongtu said, " far to send air purifier to bill gates, broke the bill gates always don't accept gifts. "" I also have air purifier in the car ... "" I travel will carry ( air purifier ), put an hour in the hotel, come back again. ”

According to the information provided by yuanda website, Zhongnanhai currently uses ta 2000 air purifier produced by yuanda in general office and other places, and adopts electrostatic dust removal technology without frequent replacement of consumables, so that the sterilization rate is as high as 99 %. 9 %, 2000 cubic meters of air purification per hour, a single effective area of 200 square meters. The price of this machine is over 10,000 yuan per set.

" the air purifier is useful, but not as exaggerated as the ad says. " air purifier agent Zhang Ai said," the principle of the air purifier is simply to inhale air, in the machine for circulation sterilization and then released. " for example, some air purification machine claims to be able to filter indoor furniture within an hour or two formaldehyde this harmful gas. The reality is that formaldehyde is a constant emission, air purification machine can't handle clean.

Lack of industry standards

It is understood that as a " special air supply" provider, yuanda company's air purifier is already a product for the company to create billions of output value. In addition to the offices and conference rooms of senior government cadres, its products also enter numerous ordinary office buildings, hotels and residential buildings.

According to some people in the industry, the whole air purification industry is not an exclusive business. At present, air purification in China has been a tens of billions of output value of the market, including Philips, Panasonic and other multinational companies and many Chinese companies are strong competitors in this market. Because of the serious air pollution in Chinese cities, these companies are using the product as a potential market.

" in the near future, in some heavily polluted Chinese cities, air purifiers will enter ordinary citizens' homes like air conditioners and will no longer be described, intentionally or unintentionally, as a' magical' machine that provides' special air' for a very small number of people. " said a CCTV commentator on the show. But Zhang Ai, an agent for air purifiers, says there is no uniform standard for evaluating air purifiers.

Zhang Ai said: " the so-called after treatment in line with national standards, is issued in 2001" civil construction engineering indoor environmental pollution control planning indoor air quality acceptance standard - GB 505325 ", but this is for indoor air. ”

Zhang Ai believes it is also difficult to assess the effectiveness of air purifiers. One is due to the indoor decoration of harmful substances, such as formaldehyde, etc., is constantly released to the outside, so can't accurately measure; The second is the effect of using air purifier, will be related to the length of use and indoor ventilation and other factors.

Zhang Ai's statement has been approved by professor Qian Hua of Shanghai environmental protection institute, Qian Hua has been developing a set of evaluation system for purification products over the years, and inspire him to develop the evaluation system is precisely, the domestic evaluation system for purification products, purifier there are some irregularities. In addition, the standard is not very in place.

" in the air purifier industry, sterilization, dust removal, nano silver antibacterial network, effective antibacterial acarid is the most common statement. Other manufacturers claim that purifier products have the ability to filter dust, eliminate odors and harmful gases, and only produce health-friendly byproducts such as carbon dioxide, ozone and water, Zhang Ai said. But in fact, too much ozone, can hurt people's lungs, lead to shortness of breath, throat inflammation, asthma attacks, etc.

On November 1, the Shanghai municipal bureau of quality supervision announced the city's production and sales of air purifier products spot checks. The TB 400 model yuanda air purifier manufactured by yuanda air conditioning co., ltd. and SJ - 1090b model air purifier manufactured by Shang Jie environmental protection technology co., ltd. are unqualified " ozone concentration percentage", which is a serious quality problem.
