Mr. Zhang, general manager of Shijiazhuang Bi Haubert Environmental Protection Engineering Co., Ltd., a designated enterprise in in addition to formaldehyde, Shijiazhuang, said that the afterheat of Chai Jing's smog investigation documentary "Under the Dome" has not dissipated, and smog has once again become a hot topic of discussion at the recent two sessions. With the same breath, * * * with the same fate, "we must strengthen information disclosure, expose all pollution sources to the sun, let everyone become a supervisor, and mobilize the whole society to jointly control smog." Chen Jining, the new Minister of Environmental Protection, said this at a press conference held at the Third Session of the 12th National People's Congress. Related reports: The air purifier has been "angered" by Chai Jing, and it is everyone's wish to completely expel the smog and return us to a blue sky. But this is not something that can be done overnight, and it takes a long process. Before the success of the "smog revolution", how to prevent the harm caused by smog became a topic of concern to the whole people. Among them, the most concerned is the PM2.5 purification artifact-air purifier. The smog "achieved" that the air purifier was affected by the smog, and the air purifier quickly spread and became a new generation of "national household appliances". According to relevant data, in 20 14, air purifiers maintained rapid growth, with a cumulative sales of 3.45 million units, which is expected to be refreshed to 4.5 million units in 20 15. General Manager Zhang of Shijiazhuang Bi Haubert Environmental Protection Engineering Co., Ltd., the most professional company in in addition to formaldehyde, Shijiazhuang, said in an interview with Hebei TV: "Air purifiers are related to smog, and the market is definitely growing. Now consumers' awareness is high, and the growth has indeed entered a period of rapid development. "Zhongyikang's White Paper on Air Purifier Market in 20 14 years also shows that the sales of air purifiers in 20 12 years were 3 10 billion yuan, an increase of nearly 40%, and the sales of air purifiers in 20 13 years were 8.5 billion yuan, an increase of nearly180. The white paper also predicts that the air purifier market will maintain a compound annual growth rate of 48% from 20 14 to 2020. At present, the air purifier market in China has formed a "tripartite confrontation" pattern-domestic brands represented by Du Ya, Midea and Gree, European and American brands represented by Philips, Bruyal and Austin, and Japanese and Korean brands represented by Panasonic, Sharp and Samsung. Aowei Consulting data shows that the market share of European and American brands exceeds 45%, Japanese and Korean brands account for nearly 35%, and domestic brands account for less than 20%. Foreign brands that are good at technology occupy about 80% of the market and occupy a dominant position in the air purifier market. Then the question is coming, when can domestic brands turn over to be masters? " Foreign brands will be more competitive at present. Two or three years later, domestic brands will come up. Because foreign brands rely on their technical strength and brand advantages. After three years, domestic brands still have advantages. "Mr Zhang told reporters. 99% purification rate? They are all deceptive. Although the smog has made the air purifier, the "mission" of the air purifier in China is to purify PM2.5, and the "bite the hand that feeds you" of the air purifier is also forced by the environment. So, what is the purification intensity of the air purifier? Almost all businesses say that the purification rate of PM2.5 is over 99%! Are these air purifiers "powerful" or "overreaching"? Everyone says that my PM2.5 removal rate and formaldehyde removal rate are 99%, and those are all lies. All air purifiers can reach 99%. "Mr. Zhang, the general manager of Shijiazhuang Bi Haubert Environmental Protection Engineering Co., Ltd., the best company in in addition to formaldehyde, Shijiazhuang, pointed out that the so-called purification rate of PM2.5 refers to the purification effect within 1 hour, and it is difficult to ensure that the purification rate reaches 99% after 2 hours, 12 hours or 24 hours. In addition, after long-term use, the filter will accumulate pollutants and the purification degree will be reduced accordingly. Since the figure of 99% is not credible, the question is, how should we choose an air purifier? Is the more expensive the better? The more expensive the better? No, speak with skill! The more expensive the better, the consumer psychology is unacceptable. " Let's simply compare the prices of several hundred dollars and tens of thousands of air purifiers. It is unreasonable to say so. We must compare other technical indicators. Just like air conditioners, there are thousands and tens of thousands. "General manager zhang said. What are the main technical indicators he said? Duang！ Accumulated purification and clean air are very important! Mr. Zhang, the most professional company in Shijiazhuang in addition to formaldehyde, told the reporter that buying an air purifier depends on the "cumulative purification quantity", which refers to the total amount of pollutants removed when the clean air quantity decays to half of the initial value during the operation of the air purifier, and measures the performance of the air purifier from the perspective of service life. It is understood that this indicator does not exist in the current national standard for air purifiers, but this important indicator will be added in the new national standard Air Purifier (GB/T 1880 1) to be released in the first half of this year. "Calculate whether its service time is 100 hours or 500 hours, 1000 hours, so that consumers can see at a glance that the price advantage of (good quality brands) comes out at once. "General manager zhang pointed out. In addition to the cumulative purification amount, the new national standard has also increased the important index of "clean air amount". The amount of clean air is the CADR value, which is used to measure the purification capacity of the air purifier. Lu Jianguo told reporters, "There are standards for clean air abroad, but our domestic enterprises have not marked this. The amount of clean air can also reflect the technical level. Just like air conditioners, they are all refrigeration, one air conditioner and two, and the price comes out. "Tips for purchasing air purifiers: 1, authoritative certification: the certification of air purifiers in the market is chaotic, and there are various international, national and local certifications. The most authoritative certification in the world is American Household Appliance Manufacturers Association (AHAM). 2.CADR value: CADR is the output rate of clean air and an important indicator reflecting the working efficiency of air purifiers. When purchasing, it depends on the CADR value published by AHAM certification. Ordinary consumers should choose products with CADR value of 100. If there are higher requirements for air quality, they should choose products with CADR value greater than 200. The higher the CADR value, the better the purification effect. 3. Air volume: Efficient purification effect comes from strong circulating air volume. The international standard requires the purifier to filter the whole room air more than 5 times per hour, and it needs to be filtered once every 12 minutes on average. For example, if the room is 20 square meters high, you need to choose an air purifier with an air volume of 20 square meters *2.5 meters *5 times =250 cubic meters/hour. 4. Demand: Different brands of air purifiers have different functions. Most of them mainly filter PM2.5, some can filter pollen, and some can remove substances such as formaldehyde and TVOC. There are also differences in technology, some focus on purification and humidification, some focus on composite HEPA filter, and some propose nano-water ion technology. Consumers should choose the appropriate purifier according to their different needs.
