Every autumn and winter, the smog is like the 'pot cover' buckled in the city, like the breath of breath, the wind comes, the haze disappears, the wind stops, the hazy comeback in the repeated confrontation haze days , People gradually realized that instead of waiting for the gale to arrive, it would be better to pay for Taiwan's air purifier to pay for it. With the stimulation of this concept of consumption, the net-free industry ushered in the rapid development.
According to the forecast, in 2017, the retail sales volume of China's empty net market will reach 6.48 million units and 19.0 billion respectively, a growth rate of 12.4% and 33.0% respectively, which is obviously higher than the traditional household appliances category. However, as the air purification In addition to smog haze effect can not be intuitive, consumers often confused when buying air purifiers, air purifiers exactly how to choose? Really as good as the company advertised it?
All manufacturers flocked into the empty net market
November 6, little-known air purifier brand 352 environmental protection science and technology first round of access to 200 million yuan financing shocked the air-clean industry, followed by Philips, millet and the mobile phone industry, net red hammer technology have also released empty net new products, coupled with Prior to the ink weather, the United States, NetEase and other Internet brands carefully cross-border entry, all forces assembled, a haze caused by the empty net war imminent.
It is understood that at present there are already more than 700 brands of air purifiers sold in the country, including both imported products, as well as traditional home appliance business and cross-border Internet companies into the potential of empty net industry potential is to inspire many businesses 'Flock' the most important factor, China National Household Appliance Research Institute, deputy chief engineer Lu Jianguo told reporters that the air purifier has developed rapidly in recent years, but not yet a leading brand, so many companies to join this ranks, want to give it a try .
At present, China's four major home appliances air conditioner, color TV, refrigerators, washing machines, 100 households have close to or more than 100 units, while the air purifier has only about 100 households, in general, the rise of empty net industry Can not do without two factors: First, the fear of haze for consumers directly promote the consumption side of the strong demand, the other is empty net industry market structure has not been stable, with the empty net upstream and downstream industry chain gradually improved, many brands Cross-border admission to seize the market.
Empty net market quite a mixed bag, the industry is now frequent chaos
This reporter has learned that the current air purifier on the market mainly passive filter purification, active electrostatic adsorption and dual purification of three forms, including passive use of physical filtration, reliable performance, the exact size of the filter particles, but need to be replaced Filter, the use of costs are relatively high; active that electrochemical filter, simple structure and without the need to replace the filter, but the filtering efficiency is relatively poor, there will be ozone production; dual purification is a combination of passive filter purification and active electrostatic Adsorption advantages and disadvantages.
However, Shanghai Jiao Tong University, Professor Wu Jixiang told reporters that from a professional point of view, the classification of air purifiers depends on the removal of pollutants in the composition of different pollutants for the classification is also different for particulate pollutants, empty net technology There are two main types of mechanical filtration and electrostatic dust removal; for gaseous pollutants, there are two main types of adsorption and decomposition; for microbial pollutants, ultraviolet radiation and electrostatic adsorption are generally used.
The air purifier mainly consists of a fan and a filter unit, which circulates and filters indoor air and outputs clean air to continuously dilute the contaminated space until a clean indicator is reached. "Like a dirty water, we use a basin of similar size water Go down to dilution, the experiment proved that after pouring about eight pots of water, the original dirty water naturally becomes clear, this is the metaphor of the birth of an empty net just started, about 50 years, the empty net or the empty net, but the story described Has begun to aliasing. 'Wu Jixiang told reporters, such as' ion waterfall', 'streamer energy', 'reactive oxygen species',' gas catalyst 'and other words, in fact, the classic empty net professional areas and there is no corresponding concept .
Since 2013, the health problems caused by haze have gradually been taken seriously by the people. The vigorous market demand makes the air-purifying industry develop rapidly. As time goes by, net enterprises have mushroomed in large numbers. However, as the industry has not yet formed effective supervision Measures, leading to chaotic market frequency, poor performance, false propaganda products are commonplace, seriously hurt the consumer confidence in the purchase.
Until March 1, 2016, the National Standardization Committee approved the release of the newly revised "GB7181-2015" air purifier "national standards for the official implementation of the empty net market brands mixed, the good and bad products improved the situation. , CCM, energy efficiency and noise of the four major indicators of strict specifications, not only the original price varies, the specifications of the empty net market has become a messy rules, but also to the purchase of air purifiers provide a reference, was As China's empty net industry an important node.
However, the reporter also learned that there are still more than 30% of the products in the market that have publicly stated that the old national standard has been invalidated. Many enterprises still mislead consumers by using the words such as "PM2.5 removal rate of 99.9%" when promoting the products Lu Jianguo told reporters PM2.5, formaldehyde removal rate of 99% or more is a basic requirement, just like the hot water bottle to reach 100 ℃, these companies deliberately avoided the time and space conditions, consumers need to confirm the time of purchase Whether the implementation of enterprise GB / T18801-2015 "air purifier" to avoid being deceived.
At the same time, the price of empty net product has always been a problem for consumers, the current price of air purifier on the market from a few hundred dollars to tens of thousands of dollars, product prices between different brands often differ Several times or even ten times the price difference so disproportionate, where is the difference between?
This reporter has learned that the two indicators of the air purifier CADR and CCM are the direct factors affecting the price of the product, the former reflects the purifying ability of the air purifier, that is, the product one hour to purify the air cubic meters, the latter CCM (in milligrams For the unit) on behalf of the cumulative amount of purification, refers to the product before the filter can accommodate the quality of pollutants, the higher the value of these two indicators corresponding to the higher the price of the air purifier.
'The national standard requires the product minimum CCM value of 3000 mg, CCRI CCM value of up to 1 million milligrams, generally better products in about 50000 milligrams, if the 300 milligram filter price of 50 yuan, That 50,000 mg price should be 830 yuan, while the price of 100 million milligrams is 16,000 yuan, the price gap lies here, that is to say the long service life of the price is certainly high. "Lu Jianguo introduced Road.
Because air purifiers are long-running appliances, an excellent air purifier not only has to be 'net' but also 'quiet.' Noise is also an important price-influencing parameter, and low noise often requires better designs and more Expensive materials to protect, so low noise products will be higher prices.
In addition, the factors that affect the price of air purifier also include material selection, design, intelligence, motor and sensor selection, etc. Currently, most of the internet brands in the market are price-to-performance products, Dragged down the consumer expectations for the overall price of empty net product sales, while publicity is often more emphasis on CADR values, and deliberately avoid the CCM, noise, energy efficiency, three indicators and design details for the price, consumers should Break the fantasy, rational treatment.
Industry reshuffle intensified, long tail brand or first out
In the context of ten-sided 'haze', the air-purifying industry in China experienced its first decline in brand participation in 2016 after experiencing an early hurricane surge in the industry. According to Zhongyikang monitoring data, in January-August 2017 The number of net sales of the brand was 483, a decrease of 40 brands over the same period of previous year.
With the introduction of the new national standard of "air purifier", the air purifier industry is faced with the challenges of brand, price, technology and other capabilities in all aspects. The long tail brand has been gradually purged. AVC monitoring data also shows that in 2017, The number of brands in the second quarter of the year was down 197 lines from the first quarter and down 20 lines less than in the first quarter of 2010. According to the insiders, the rapid rise in the number of brands is a sign that the industry has entered a prosperous period, Climbing decline, the industry shuffle, the optimization of the competitive signal.
It is understood that, in addition to the new national standard "air purifier", the future will be more fragmented standards will be released and implemented one after another, "air purifier filter" and "air purifier electrostatic dust filter" standard has been Into the final stage, is expected to be officially introduced in 2018.
In addition, the reporter also learned that in the new version of the "Standardization Law" passed by the Standing Committee of the National People's Congress on November 4, it was explicitly required that the enterprises explicitly implement the names of the mandatory and recommended standard numbers. This law was promulgated on January 1, 2018 After the implementation of the enterprise implementation of national standards, especially the recommended standards play a powerful role in promoting.Lu Jianguo said: 'Legal means to monitor the implementation of national enterprises, industry standards, which make air purifier enterprises to implement GB / T18801-2015' Air purifier "has become a necessity.
Tips: easily overlooked detection of 'misuse'
For ordinary consumers, in addition to concern about the purchase of air purifiers, how to correctly measure indoor air PM2.5 index is the most easily overlooked place.Wu Jixiang introduction, PM2.5 concentration should be detected in the activities of someone in the position, Detector height should be very high with the human respiratory zone, about 1.5 meters.
'Consumers should not only understand the current PM2.5 concentration, but also pay attention to continuous PM2.5 concentration and PM2.5 average concentration throughout the day', Wu Jixiang introduction, the international PM2.5 concentration daily average concentration standard is less than 25 micrograms per cubic meter for every 10 micrograms / cubic meter added, the negative health effects are all weighted and harmful. Most urban centers in China have a daily average concentration of more than 50 micrograms / cubic meter in autumn and winter. The most polluted The weather even exceeded 500 micrograms / cubic meter, which is a very serious phenomenon, but unfortunately has not caused the collective concern of all consumers.
It should be noted that formaldehyde is also an invisible killer in the indoor air, newly renovated room formaldehyde release time can be up to 3-15 years, for high formaldehyde pollution occasions, relying on a single technology is difficult to effectively control the need for ventilation, control and use Air purifier integrated approach to control, but only when the removal rate of formaldehyde purification purifier exceeds the rate of formaldehyde emission of interior materials, in order to effectively control the formaldehyde concentration of formaldehyde is currently the international concentration of less than 0.03 micrograms / cubic meter is set to Children acceptable concentration, it is understood, high CADR formaldehyde air purifier is being developed, the formaldehyde CADR value required to reach 700 micrograms / cubic meter or more.
Overall, the rapid development of China's empty net industry, many enterprises run into the market chaos gradually overcome, Professor Wu Jixiang, clearly optimistic about the demand side under the influence of a large number of developers and investors into the empty net industry It is estimated that the air market as a whole will be rapidly developed and expanded in the next few years, and the industry will continue to survive and survive. The overall healthy and rational growth will be maintained.
