In 2013, China suffered the most serious haze in the history. On December 25, the Christmas Day, according to the statistics made by the reporter based on the information released by the Central Meteorological Bureau, Shandong, Hebei and Anhui provinces issued provincial early warning about haze that day while as many as 25 prefecture-level cities issued the early warning. Two days before this day, the daily concentration of fine particulate matter PM2.5 in the air of most regions in China rose obviously. On the Christmas Eve, local part of Beijing, Tianjin, Hebei, Shanxi, Henan, Shandong, Shaanxi and Jiangsu suffered heavy haze. A netizen ridiculed that he/she had spent an unforgettable haze Christmas when “one can only hear the voice but cannot see the people”. The occurrence frequency, coverage and pollution degree of haze were unprecedented. The level of PM2.5 was even beyond the index. The visibility during the day was less than dozens of meters. The middle and primary schools had to suspend classes, the flights were grounded, the expressways were closed and buses were suspended.

There are for large-scale haze processes in the country, involving 30 provinces (autonomous regions and cities). The levels of PM2.5 in many cities were beyond the index. Hazes with the longest duration, the most extensive scope of influence and the strongest strength appeared in most eastern part of China. Survey data of the Ministry of Environmental Protection in January showed the average days appearing haze in Jiangsu, Beijing, Zhejiang, Anhui and Shandong were 23.9, 14.5, 13.8, 10.4, and 7.8 respectively, which were all the most over the same period in these places since 1961. The number of days with the concentration of PM2.5 beyond the standard in most sites of East China reaches 25 or more, and the level of PM2.5 in some regions even has reaches the highest value in recent five years.

For the deep-seated causes of haze, industry experts said the extensive economic development mode can hardly absolve itself from the blame. In 2011, China’s GDP accounted for 10.8% of the world’s economy but consumed 60% of the world’s cement, 49% of the world’s iron and steel and 20.3% of the world’s energy, and these “two highs and one capital” industries are mostly concentrated in the eastern region. Extensive economic development pattern and not reasonable enough industrial layout result in lots of air pollutants.

On the other hand, coal-fired emissions caused by unreasonable energy structure are still the main cause of air pollution. For a long time, the proportion of coal in China’s energy consumption has been about 70%, but the proportion of clean energy is low. In 2011, China’s coal consumption exceeded 3.5 billion tons, large quantity of pollutants caused by which result in a tremendous pressure to the atmospheric environment.

Director of the Chinese Society of Environmental Sciences Motor Vehicle (Ship) Pollution Prevention and Control Committee Bao Xiaofeng said that motor vehicle exhaust emissions have become the largest source of air pollution in large and medium-sized cities. In urban atmosphere, 80% to 90% carbon monoxide, 70% to 80% carbon oxides, and 50% nitric oxide are from vehicle emissions. “Motor vehicles can discharge more than 200 kinds of chemical pollutants. The harmful gases a car discharges a year can be up to 3 times of the weight of it. There are fundamental problems of domestic fuel from refining to the actual combustion process, resulting in poor fuel quality and insufficient burning.

According to the forward-looking industry research institute released the "China's air purifier industry market demand forecast and investment strategic planning analysis report" data show that (including 2013) the next five years, China's air purifier sales will maintain 30% -35% high growth, The next three years the total market will likely reach 19.5 million units, 25 million units, 34 million units; is expected by 2015 China's air purifier industry market size or can exceed 60 billion yuan, 2017 can reach 100 billion yuan. 100 million city family, tens of millions of office, hotels, hotels, fitness, entertainment, the annual market consumption of 1.5 million tons of formaldehyde, benzene compounds, more than 200 million people directly affected, hundreds of billions of market look forward to development!


China's real estate and auto industry in the next few years will be rapid development, the two industries will be the next long period of time the main consumer hot spots. And indoor environmental pollution and indoor environmental pollution is still quite common, very serious, coupled with people's understanding of environmental pollution hazards more and more profound, making more and more people began to pay attention to indoor and indoor environmental pollution problems, began to pay attention to indoor And the car environment and expect to be treated.
