[PConline Qiuzhen Laboratory] One month ago, Qiuzhen Jun sent 10 air purifiers to the Guangzhou Institute of Microbiology for testing. One month later, 10 authoritative test reports have been sorted out! Qiuzhen can tell you which manufacturer is lying!
Not much nonsense, let’s summarize the results of this time for everyone, and review the basic parameters of 10 air purifiers:
z2, the first part of the test is 0801z
zzzz2. Air purifier products are Daikin KJ421F-N01 (formaldehyde purification performance suspected to be false), Dyson TP04 (formaldehyde purification performance suspected to be false) and MUJI MJ-AP1CN (noise exceeded). (I want to give a thumbs up to the domestic brands)

according to the testing data of the Guangdong Provincial Institute of Microbiology and Guangdong Provincial Institute of Microbiology and Guangdong Provincial Environmental Sanitation Standards. The 10 air purifiers are scored . The specific scores can be viewed in the following ranking:
The score is based on the star rating standards developed by PConline and the Guangdong Indoor Environmental Sanitation Industry Association and issued by the China Quality Inspection Association. For details, click here Check the comprehensive PM2.5 and formaldehyde purification performance of
here. The best performer is Supor KJ800G-S60, with a comprehensive performance score of 77.1. The purification performance of particulate matter and formaldehyde received 9 and 8 stars respectively. But after all, the price of 8999, you get what you pay for. The comprehensive performance of
Supor KJ800G-S60 is reasonable.
Whirlpool WA-3801SFK and Changbreath KJ800G-JT02 (Super Formaldehyde Removal Edition) rank second and third in comprehensive performance scores of 69.5 and 64.6 points. They are priced at 1999 and 2899 yuan respectively, which is only a quarter of the price of the one just now. (For large spaces, choose to breathe, and for small spaces, choose Whirlpool).
Lao Luo's breathing is still relatively stable.
This year Seeking Truth has tested 31 models of air purifiers, a total of 11 models are unqualified, and made the list of air purifiers. Interested users of can follow the public account "Seeking Truth" Laboratory XLAB", backstage reply "Ladder map" to view~
If it is a product that is not available in the ladder map, and you are too lazy to check the complicated star rating standards, Qiu Zhenjun also prepared a simplified version of for you to purchase an air purifier Guide , pick it right, the problem is not big:
Get back to business, let’s analyze these 10 air purifiers in detail below. declares in advance that Qiuzhen’s test results are only responsible for the air purifiers purchased by Qiuzhen. The test data and scores do not represent all products of the same model on the market, let alone the performance of these brands. What did
have tested?
Qiuzhen entrusted the Guangzhou Institute of Microbiology to conduct particulate matter CADR, formaldehyde CADR, noise and power consumption inspections on these 10 air purifiers . The Guangzhou Institute of Microbiology has a very high reputation in the field of air purifier testing. It is also the drafting and revision unit of a number of national, industry and group standards. The test report issued by it has legal effect and can be said to be very objective and authoritative.
1, CADR
particulate matter, formaldehyde CADR represents the air purifier's ability to purify suspended particulate matter (such as second-hand smoke, PM2.5, dust and other particles) and gaseous pollutants (such as formaldehyde, toluene, etc.) in the air. The larger the value, the greater the purification ability it is good.
According to the test results of the Guangzhou Institute of Microbiology, the particulate CADR and formaldehyde CADR of 10 air purifiers are shown in the following figure:
The measured data of particulate CADR and formaldehyde CADR, the products are sorted by price from low to high, you can see the high price Not necessarily equal to high-performance
particulate matter CADR
sorted by particulate matter CADR from high to low, the second most expensive Dyson TP04 is actually the bottom
. From the results, the particulate matter CADR and formaldehyde CADR of the 10 air purifiers have a relatively large gap. Based on previous Hengping experience, Qiuzhen also found that most of the air purifiers on the market are partial, and the CADR of formaldehyde is much worse than the CADR of particulate matter... does not know whether it is a technical problem or intentional. . In terms of particulate CADR, Breathing KJ800G-JT02, Supor KJ800G-S60 and Lake AP71 are among the top 3, and the particulate CADR of other products is not too top-notch. here focuses on Dyson TP04. Although the product name is an air purification fan, the high price of 4950 buys 151.6m³/h of particulate matter CADR, which is half less than the product of less than 1,000 yuan. This is really sold as a fan...
but the product name of Dyson TP04 is "air purification fan" instead of "air purifier"...
formaldehyde CADR
It is the most prone part of air purifiers to have performance false standard problems. Z2z Qiuzhen has tested 31 air purifiers. There are as many as 5 models with formaldehyde CADR performance false standard, accounting for 16% of the total . It seems that various manufacturers The formaldehyde adsorption function is still slightly sloppy.
get back to the subject, the best measured performance of formaldehyde CADR is Supor KJ800G-S60 and Changbrea KJ800G-JT02, the measured data are 455.8 m³/h and 367.6 m³/h respectively. Whirlpool WA-3801SFK formaldehyde ranked thirdCADR measured 141.7 m³/h. The rest of the air purifiers that participated in the evaluation are all less than 100 m³/h, which is a bit too low to be honest. Consumers who want to use it to remove formaldehyde must be cautious in buying. Seeking the truth is to reiterate that the best way to remove formaldehyde is to ventilate, ventilate and then ventilate. Air purifiers can play an auxiliary role, but not A permanent solution.
This Hengping Daikin KJ421F-N01 and Dyson TP04 both have formaldehyde CADR false standard . Among them, Daikin KJ421F-N01 does not indicate the formaldehyde CADR value in the manual, but Daikin Purifier Jingdong self-operated flagship store The specifications and packaging list of the formaldehyde CADR is 66m³/h, while the measured value of Guangzhou Institute of Microbiology is 57.2m³/h. The measured value only reaches the nominal value of 87%, which does not meet the national standard GBT 18801-2015 90% requirements.
The nominal data of Daikin’s official flagship store is compared with the measured data of Guangzhou Institute of Microbiology. The nominal value is 56m³/h, and the Dyson TP04 purchased by Qiu Zhenjun has been tested by the Guangzhou Institute of Microbiology. The CADR of formaldehyde is 40.3m³/h. The measured value of is 72% of the nominal value. This error It's really outrageous. It seems that the IQ tax accounts for most of the 5,000 yuan plastic fan.

2, noise
Although CADR determines the purification performance of an air purifier, is not an option when purchasing an air purifier The higher the CADR, the better the product . High CADR will cause a significant increase in noise. If the noise is unbearably loud, no matter how high the CADR is, no one wants to put a bomber at home.
sorted by noise sound power level data from low to high
The lowest operating noise is Whirlpool WA-3801SFK, and the highest windshield noise is 59dB(A). Next are TCL TKJ-F220B, Daikin KJ421F-N01, Dyson TP04, and the rest of the air purifiers are around 65dB(A), and the operating noise at the maximum wind gear is a bit loud.
According to the national standard GBT 18801-2015, the measured noise of air purifier shall not be higher than the nominal noise value of 3dB(A) or more . The nominal noise value of MUJI MJ-AP1CN is 60dB(A), and the measured noise But it is as high as 73.1 (A), which is a full 13.1dB (A), which is a bit exaggerated...

I’m afraid it’s not flying a plane
and the official website of MUJI MJ-AP1CN and Jingdong flagship store page are not marked with any performance parameters (yes, any) , only after Qiuzheng bought this air purifier You can see the nominal value of clean air volume and noise in the product manual, and the label of clean air volume is not marked in accordance with the national standard GBT 18801-2015. It can be said that it is very irregular. Buying this air filter at is probably the same as the lottery... …Z3z
MUJI’s official website and Jingdong flagship store do not have any performance parameter identification......
3, CCM
CCM refers to the cumulative purification volume when the CADR value of the air purifier decays to 50%. Simply put, it is the total amount of pollutants that the filter can hold. CCM is divided into particulate matter CCM and formaldehyde CCM. The grade ranges from the lowest level 1 to the highest level 4. The higher the level, the greater the cumulative purification capacity of the air purifier filter and the longer the filter life .
Nominal data on the energy efficiency of particulate matter and formaldehyde purification, the products are sorted by price from low to high. Z6z
Qiu Zhenjun did not commission the Guangzhou Institute of Microbiology to test CCM, because the CCM test takes a long time, after all, it is to measure the time spent on the filter element. , Please use their nominal data to sort it. When we buy air purifiers, we also try to buy products with particulate matter and formaldehyde CCM reaching P4 and F4 grades, so that the life of the filter will be longer, and it can be replaced every six months or a year. If the grade is lower, you may need 3 Changed around the month.
4. Power consumption
Power consumption is a better parameter to understand. It depends on the efficiency of the air purifier. The air purifier national standard GBT 18801-2015 has regulations on the energy efficiency of air purifiers, which are called "purification energy efficiency". purification energy efficiency = particulate matter CADR/formaldehyde CADR ÷ power , so it is also divided into particulate matter purification energy efficiency and formaldehyde purification energy efficiency. The energy efficiency of means eating less and working more, the higher the better. The national standard of
stipulates that the particulate matter purification energy efficiency reaches 2 as the qualified level, and reaches 5 as the high-efficiency level. The formaldehyde purification energy efficiency reaches 0.5 as the qualified level and 1 as the high efficiency level. However, the star rating standards jointly formulated by Qiuzhenjun PConline and Guangdong Indoor Environmental Sanitation Industry Association are more stringent, and the particulate matter purification energy efficiency is more than 8 and the formaldehyde purification energy efficiency is more than 4 to be considered excellent.
Particles and formaldehyde purification energy efficiency measured data, the products are sorted from low to high price. In order to achieve the purpose of saving energy, I would like to recommend purchasing products with high efficiency for both particulate matter and formaldehyde purification. The higher the value, the better. According to Qiuzhenjun's more stringent standards, only Supor KJ800G-S60, the , has achieved excellent performance of both particulate matter purification energy and formaldehyde purification energy efficiency. The rest of the products are defeated in the energy efficiency of formaldehyde purification. If you only look at the energy efficiency of particulate matter purification, the energy efficiency ratios of Muji Air Purifier, Xiaomi Air Purifier 2S, Lake AP71, Supor KJ800G-S60 and Whirlpool WA-3801SFK are all good.

2018 Air Purifier Hengping Summary
31 sets of air purifiers were tested. All the data of comes from the authoritative third-party testing organization (Guangzhou Institute of Microbiology and Guangzhou Zhongke Testing of Chinese Academy of Sciences) , and the results are objective and reliable. Among these 31 air purifiers, 11 have some test items that do not meet the requirements of the national standard GBT 18801-2015 . Although this national standard is a recommended standard and has no compulsory effect, consumers still want to buy it in accordance with the publicity This is a reliable and reliable air purifier product, so Qiuzheng still hopes to strictly point out the substandard parts of these products for everyone, and also hopes to play a certain role in supervision of manufacturers.
Here I will take you to review the product models and reasons that did not meet the standards in the first and second quarters
Next year, Qiuzhen will continue to introduce air purifiersConduct quality surveys, may expand its focus from household air purifiers to larger areas such as fresh air purifiers and car air purifiers. At the same time, it will also bring everyone the same high-level attention to quality surveys of water purifiers. , I hope that next year everyone will also support Qiuzhen.
