In the 315 of the PConline survey , it was guessed by major media that one of the “blacklist†air purifiers did not make its debut, but the problem of the air purifiers’ transitional imaginary standards was still very serious. CCTV had repeatedly reported that the air purifiers were false Applicable area and other issues. Air purifiers, as polluting air, as effective filters to pollute the air and protect the user's breath-healthy appliances, merchants love to seize this point and start crazy to step into this product line. Not only is the homemade mountain cottage empty and net, but also some Japanese and American brands have the same phenomenon of virtual standard parameters. From March 1st onwards, will the implementation of the new empty net national standard help the consumer? We will visit various major shopping malls and online channels to see if there are any changes in the indicators such as the net purchase parameters.
In fact, the new national standard for air purifiers is the “Help Life†for the nation to effectively rectify chaos in the air-to-air market. From March 1 this year, the new air purifier “GB/T-18801-2015†was formally implemented. standard. It is considered by the industry insiders to clean the air purifier industry's "scrape." Effectively constrains manufacturers to develop air purifiers with higher purification capabilities and service life. The new standard clarifies the core parameters of the air purifier: clean air (CADR for short) and cumulative clean (CCM for short). It is used to indicate the cleansing power of the air purifier and the sustainability of the purifier. The noise limit of the air purifier is divided into 4 blocks from low to high; the energy efficiency level of the air purifier for different pollutants purification capacity is improved, which is divided into qualified and highly efficient grades.
The new national standard requires the purifier "three high and one low"
The high clean air volume (CADR value) and CADR value are the core indicators of air purifiers. The higher the CADR value, the faster the purification efficiency and the larger the applicable area.
With a high cumulative cleanup (CCM value) , CCM is regarded as a stricter value than international standards. It can react to the use of air purifier filters for a long time. A high CADR does not mean that the air purifier is effective. Only when the CCM is also high can it prove that this air purifier not only has a high purification efficiency, but also has a strong purification capacity and a longer filter life.
High energy efficiency rating , which refers to the ratio of CADR to rated power, which is the standard for power consumption. For the particle purification energy efficiency value, 2 qualified grades, 5 high efficiency grades, for formaldehyde and other purification energy efficiency, 0.5 is a qualified grade, 1 high efficiency grade.
Low noise level , this is more straightforward, if you put an air purifier at home, the sound of the start like the roar of the engine engine, and then efficient purifier will not be flattering. In the new national standard, there is a clear provision that the noise limit of the air purifier is divided into 4 levels from low to high.
Although the new national standard clearly stipulates the above parameters, it is hateful that these parameters are not mandatory. Some products implement recommended national standards. This not only inconveniences consumers in comparing and discriminating air purifier products, but also makes it difficult for law enforcement agencies to judge the quality of purifier products.
Having said so much, consumers are always right to follow this "three highs and one low" shopping skills. But is the real situation so simple? Can it be implemented in accordance with the provisions of the new national standard? Or according to the manufacturer's own set of standards? Can consumers easily judge the quality of products? With a lot of questions, Xiao Bian's spirit of serving the people personally visited online and offline shopping malls. After March 1, the stores were all implemented in accordance with the conditions of the new national standard.
Shanghai sales network avoids talking
Xiao Bian came to a large nationwide chain appliance shopping mall, you can see on the counter a Sharp KC-CE50-W price is 4599 yuan and IQAir HealthPro 250 price is 14980 yuan, these two empty net if from the price The distinction is between the mid-range and high-end series. However, they did not explicitly tell the user about its CADR value, CCM value, and energy consumption and noise.
KC-CE50-W Air Clean Parameters on Sharp's official website
HealthPro® 250 official website
Xiao Bian can only find the two vacant detailed parameters on the Internet. It can be seen from Sharp's official website that the air purifiers it currently sells are in accordance with the new air purifier "GB/T-18801-2015". National standards are tested. However, the HealthPro® 250 is still in the purification efficiency: the efficiency of removing particulates with a diameter of 0.3 μm is ≥ 99.97%, and the efficiency of removing smaller particulates is ≥ 99.5%. The only explanation is that in the case of 6 fan speeds, the maximum air output is 440m3/h. The CCM value, silence, and energy efficiency all have nowhere to go.
Blueair will wake up target parameters
During the visit, there are still conscientious companies that identify the performance parameters of the product to the user, and it will be listed that this parameter is based on "GB/T-18801-2015" with specific soot particulate matter or a single gaseous pollutant as the target, and Tested under laboratory conditions. The more marked CADR value is the result of the purifier standard filter.
Guangzhou sales outlets do not understand
The lower sales of purifiers in Guangzhou than in North China may be due to improvements in air quality in recent years. The Minister of Environmental Protection has also mentioned in a press conference recently that the concentration of PM2.5 in the entire Pearl River Delta region has reached the standard last year and has become the nation’s first priority area for compliance. In fact, during the purchase of air purifiers in the Pearl River Delta, more attention was paid to the removal of gaseous pollutants such as formaldehyde and TVOc.
The sales staff on the booth did not understand the relevant parameters of the new national standard
Most of the air purifiers can be seen during the visit. In fact, no real purification performance was indicated. In addition, some purifiers were marked with the slogan “PM2.5 removal rate >99%â€. When referring to CADR, CCM, etc., to some sales aunts, they expressed a loss. Xiao Bian noted that some of the vacant products that did not mark the new national standard were all engaged in promotional activities. Perhaps the product will be delisted soon.

The removal rate of PM2.5 is used by most manufacturers for experimental values. If the detection is performed at a specific location such as an air outlet, it can theoretically reach 99%. However, in the actual opening of the purifier, the consumer's removal rate of 99% is of no practical significance. It can only be said that the purifying effect can be achieved in a short time and in a closed environment.
Detailed explanation of on-site staff
The length of life of the filter element and the use environment, the length of boot time, the level of the file have a strong correlation, how long the standard for a time, there is no practical reference value, most manufacturers currently on the market still rely on the formula to calculate the life of the filter, Instead of judging it according to its actual usage effect, the filter replacement time can only be used as a reminder by the user.
Online mall tagging parameters clear
We compared a number of online malls and found that they were completely different from the physical stores. Consumers have different ways to purchase product references in online stores. Stores can personally feel the appearance of the product, workmanship, and inquiries about the sales staff around them. The online shop can understand the product's purification performance, service life, and detailed parameters. Brand awareness to judge the quality of the product. However, Xiao Bian will be reminded in this regard, although the e-commerce logo product performance is compounded by the new national standard, but it is still necessary to see clearly whether the clean-up effect is to mark particles or gaseous pollutants. Some companies will refrain from talking about the ability to purify harmful gases such as formaldehyde.

The brand-name air purifiers exhibited by e-commerce companies clearly inform consumers that they are in compliance with the new national standard GB/T-18801-2015, and are tested in terms of CADR values, CCM values, energy efficiency levels, and noise. Consumers can judge product performance, and can also measure and purchase according to the environment they need to clean, compared to the physical store.
Samsung air purifier is also marked with the certification of the new national standard.
Tmall Mall issued an announcement to the merchants earlier, notifying that the time for the introduction of the new national air purifier was required, and required that the manufacturer's air purifier on Tmall must provide the relevant qualification certificate for the new national standard, and related to the air purifier. Product review.

The full text concludes: From Xiao Bian's visit to various supermarkets, the new national standard for air purifiers has not been quickly implemented. Some air-to-air companies still use slogans such as “removal rate >99%†to mislead consumers in their promotion methods. The CADR and other reference values ​​have not been marked in accordance with the provisions of the new national standard. The online e-commerce business is completely different. Both foreign and domestic brands have already passed the new national standard test. Although the new national standard does not have mandatory labeling, consumers should select an appropriate air purifier according to the actual conditions of their own use and based on the parameters of the new national air purifier.
