Beg true lab to be in major detected last year the orgnaization cooperates, checked 3 period, gross 31 air purifier, discovered 11 circumstances that do not amount to mark, so tall do not amount to mark rate to explain air purifier trade is total quality still not hopeful, consumer needs more sharpen one's eyes goes differentiate.
Latest issue of like us in the test, 10 products have 3 products to turn over, there is no lack of among them have mix like big gold taste such everybody's hep brand without Yin Liang.

And Qiu Zhenjun impression is the deepest is not above those 2, however another often can see in friend circle somebody obtains beautiful trademark, right, it is Dai Sen.
Feel embarrassed Oh Oh, the graph that put a fault. This is the figure of to turn over that foreign netizen checks club of Dai Sen curl
The tide that the club of Dai Sen curl of 3690 furls in friend circle lets ￥ Qiu Zhenjun has bit of Jing to drop chin, so expensive still does so much person want to buy?
Does air purifier behave those 5000 Dai Sen how? Does air purify effect value to not worth this price? We talk with actual measurement data, take the advantage of this 315 will make dozen of holiday.
TP04 of ▲ Dai Sen everybody should very look familiar
This sample is Qiu Zhenjun is wearing Sen Jingdong at one's own expenses self-supporting flagship store is bought. Microbial institute of city of the Guangzhou before undertaking detecting undertook to sample sufficient and comprehensive examination, make sure sample is run normally.
Cut of ▲ government storefront pursues
Someone says: It is being written is air purifies circular fan!
But it already by Beijing east classify is in air purifier, and the name already tagged the function that has air purifier, can " purify whole house space " , it is right that that undertakes according to the standard with clean air.
The grain content CADR that we basically check sample, formaldehyde CADR, power comsumption and noise 4 projects, undertake strictly detecting according to national level GBT 18801-2015, these 4 index can mirror an air purifier adequately purify function, use experience and circumstance of specific power consumption, these index are can quantify, enough and objective.
For this, the astral class that Qiu Zhenjun saves guild of indoor environment sanitation to make according to PConline and Guangdong criterion for evaluation, simplify piece below this form, how does reference differentiate outstanding air purifier for everybody:
Still put actual measurement data first likewise, detect the report comes from Guangzhou city microbial institute, the government is nominal the value comes from a product to pack, page of merchandise of shop of manual, government.
▲ detects report
Note: Of course this result sends this verity Dai Sen air purifier on behalf of Qiu Zhenjun only, do not represent all function that are the same as air purifier of type product and Dai Sen other to behave
Section of ▲ government information pursues
Dai Sen is very good still fair show oneself purify performance data, that after all practical effect how?
CADR
CADR of grain content, formaldehyde purifies substance of grain of float of air horizontally pivoted hung on behalf of air purifier (be like secondhand the particle such as smoke, PM2.5, dirt) and gaseous contaminant (wait like formaldehyde, toluene) ability, numerical value expresses to purify ability to had been jumped over greatly more.
The grain content CADR of air purifier of TP04 of this Dai Sen is actual measurement of Guangzhou city microbial institute 151.6m3/h, the 164.3m3/h that publicizes with the government differs 7.7 % , the brim is worth to explore in the deviation of the 10 % of national level GBT 18801-2015.
But the grain substance that actually value of this grain content CADR of 150 purifies 11-18 square metre quite only, can saying is this second horizontal stroke one performance is the poorest is purified in judging. The sitting room in the small companionate home of the bought air purifier that has 5000 silver dollar is more than ten smooth rice. Dai Sen says " purify whole house space " , make room 18 is smooth rice big?
Government of ▲ Dai Sen publicizes a page
Formaldehyde purifies function to was about to criticize, the government tags 56m3/h, actual measurement of Guangzhou city microbial institute is only 40.3 M3/h, difference 15.7m3/h, deviation is as high as 28% , exceed the deviation of the 10 % of national level GBT 18801-2015 badly to be worth. Nominal applicable space still can have 3.9~6.7 to make the same score rice, measure a can applicable 2.8~4.8 actually to make the same score rice. Very frail, it is the product that this second test formaldehyde purifies function penult. (a bit good taste air purifier at hardly what formaldehyde purifies ability do not have Yin Liang)
Do not have Yin Liang to taste: I not face? !
Noise
We know to purify mode completely for nothing stronger, hard to avoid of empty only sound can greaten a bit noisy even, so noise test also is the key that Qiu Zhenjun must pay close attention to, this concerns air purifier to use the stand or fall of the experience, after all CADR is again tall, the meaning also is done not have if noise must be borne hard greatly.
▲ demands Zhen Jun's only to outstanding sky standard
The value of grain content CADR of Dai Sen TP04 should return for ≤ of 150 ＜ CADR this groups 300, noise is less than 55dB(A) to be outstanding, and actual measurement noise is 61.9 DB(A) , the government alleges is 59 DB(A) , exceeded 2.9 DB(A) , it is all but dot what do not accord with regulation of GB GBT 18801-2015 is most exceed 3dB(A) , so weak purify function to return so can noisy.
CCM
CCM is to show the CADR of air purifier is worth attenuation to purify a quantity to the 50% accumulation when, simple for it is the gross that mesh can accommodate contaminant, represented the service life accident of mesh. CCM cent is grain content CCM and formaldehyde CCM, grade arrives from 1 class of lowest top 4 level, grade purifies a quantity higher on behalf of the accumulation of air purifier mesh bigger, mesh service life is longer.
The grain content CCM of Dai Sen TP04 is P4 grade, it is the highest order and degree that at present GB provides, the life of mesh of H-13 level PTFE HEPA that is in charge of purifying grain substance is quite good still. But the grade that did not tag formaldehyde CCM, seeing only is activated carbon.
Power comsumption
This parameter had compared power comsumption to understand, air purifier cost does not expend report to see it. Have in GBT 18801-2015 of air purifier GB to air purifier can the regulation of effect, its call " purify can effect " . Purify can power of ÷ of CADR of formaldehyde of CADR/ of content of effect = grain, because this also is divided,purify for grain content can effect and formaldehyde are purified can effect. Can effect is tall have a meal namely little work much.
The regulation of GB is, grain content is purified can effect is achieved 2 for acceptable level, achieve 5 for efficient class, and this covers Qiu Zhenjun the standard is rigidder, achieve 8 ability to calculate outstanding. The grain content of Dai Sen TP04 is purified can effect is 4.83, do not have the efficient class of GB, can calculate qualification only.
Additional, GB stipulates formaldehyde is purified can effect is achieved 0.5 for acceptable level, achieve 1 for efficient class, the formaldehyde of Dai Sen TP04 is purified can effect is 1.3, although did not achieve Qiu Zhenjun to think outstanding level (4) , but the efficient class that also had been GB regulation.
Overall assessment
CADR of ▲ grain content reachs data of formaldehyde CADR actual measurement, the product presses price from low to tall sort
Qiu Zhenjun sent 2 plans, the 2nd graph can see, the price is ranked the 2nd (nearly 5000 ocean) the performance of air purifier of Dai Sen TP04 is very poor, not agree with with its social status apparently, can saying is " dye-in-the-wood " vase.
Purifier of ▲ Dai Sen Beijing east self-supporting flagship store publicizes a page
Someone may say this is a fan only, but page of conduct propaganda of Dai Sen government is connected piece " purify air " " eject clean headroom is angry " expressions, let a person feel this is to avoid in false conduct propaganda. And the fan that this sells 5000 RMBs, tax of how many intelligence quotient to contain after all?
So Qiu Zhenjun suggests to want to purify air, dai Sen TP04 deserves a consideration least of all. Local tyrant wants to blow hair drier, optional.
Also hope everybody is when the product of the Dai Sen brand of angle high price, can much portion is rational, a few less peacockish impulse. Hope Dai Sen does a product to have more while the design has appearance, make good intention, a road that publicizes a few lesser.
The astral form that according to sanitation of condition of core of PConline and Guangdong province room guild makes criterion for evaluation, qiu Zhenjun gives thing of verity grain of TP04 of this Dai Sen to purify function to make 4 stars, formaldehyde purifies function to make 4 stars (full marks is 9 stars) , integral performance grading is 31.3 minutes (full marks 100 minutes) .
There also is money reward of course beyond criticism, last year on November 28, save indoor environment sanitation by Guangdong foundation of development of medicine of the hill austral net of household of network of computer of guild, Pacific Ocean, Pacific Ocean and Guangdong province sponsors " air of 11.28 the whole people is clean section " , it is the large award that year of empty only industry has one of force most.
Activity that day, 40 experts inside air purifier course of study share selection work, below the testimony of tens of hundreds guest, home media, zhong Nashan of academician of Chinese Academy of Engineering personally the large award of air purifier industry of coronal name " south hill award " , issue the brand that force has most in industry of annual air purifier and the product that provide innovation spirit most.
We hope these outstanding empty only firms can produce his leading effect, ceaseless innovation enterprising, continue to offer more cheap and fine empty only product for broad consumer.
To invite customer more conveniently air purifier of choose and buy, network of Pacific Ocean computer rolled out clean pop chart of industry head Zhang Kong, consumer can understand the function seniority that goes examining the air purifier that already measured simply, understand the brand product that did not amount to mark ahead of schedule, convenient make right choice!
