Afterwards after 315 evaluation, a lot of netizens offer to beg Zhen Jun to do the horizontal stroke of air purifier to judge, begged true lab to had evaluated 31 air purifier last year actually, enclothed 600, 9000 yuan of price, as a result discovery had 11 to appear not to amount to mark among them even the circumstance of breakdown, fraction defective is achieved 3 into, make Qiu Zhenjun a bit amazed, also plaint empty only industry also is good and evil people mixed up.
We send detected setting
The division in Guangzhou of microbial institute of we and Guangdong, Chinese Academy of Sciences detects wait for professional orgnaization collaboration, according to level of air purifier state " 18801 " regulation, according to 5 index: Grain content CADR, formaldehyde CADR, CCM of dust containing capacity, noise, effect, applicable area (choose bid) will detect the real property that sends measured air purifier.
Not clear young associate is OK the first phase on reference the evaluation of 2000 yuan of archives: Is cheap = poor? Horizontal stroke of 2000 yuan of the following air purifier is judged, millet empty sign is clear
The young associate of understanding looks downward then:
We measure a millet empty mark formaldehyde purifies parameter, really everybody should learn money or a minute of money one minute, so we measured 2000-3000 again yuan 11 air purifier, the result is as follows:
Expression is best is Airx KJ800G-A8, grain content CADR and formaldehyde CADR be among the best of candidates, fit the 90 household environments of smooth rice, the clean airy demand of family of basic contented majority.
The free that must carry Laoluo next breathes air purifier, issue the first air purifier as banner of hammer science and technology, true integral charge for the making of sth. holds out conscience, grain content CADR is as high as 812.3 M3/h, content of 3000 yuan of when be us to check the following the strongest grain purifies ability, be being put on market also is the person that above average. Formaldehyde CADR value also has 367 M3/h, very pretty good also. Although hammer already swaying in the midst of a raging storm (do not receive advertisement this piece to expend with a ha breath out) , dan Chang breathes to had been bought by advantage science and technology, the problem after making work so should need not worry, the young associate with the large space in the home can consider.
Fall for now fail! !
- 352Pine of KJ421F-N01 of X83 big gold issues F-VXG70C
Be everybody's hep big plant! How with respect to to turn over?
They made same wrong: Actual measurement of formaldehyde CADR value and propagandist worth difference are too big, exceeded the of 10% error value that the country provides.
In light of analytic --
352X83 report is analyticalDetect report part is chosen
352The grain content CADR of X83 and nominal about the same, the grain content CADR of 744.5m3/h is really special and pretty good. Formaldehyde purifies a respect, the CADR of actual measurement formaldehyde of 352 X83 and nominal the value differs 16 % , difference is bigger, doubt seems empty symptom, also cannot eliminating of course is the sample that we buy has quality problem, cannot judging this performance gap so is an exemple or common phenomenon.
Report of big gold KJ421F-N01 is analyticalAs a whole, the thing of grain of KJ421F-N01 of this big gold that Qiu Zhenjun buys purifies function to return OK, noise, CCM and power comsumption also calculate pretty good, but formaldehyde purifies function empty mark and the condition that is in it doesn't matter basically to use, slant quite division.
Purifier of ▲ big gold Beijing east self-supporting flagship store publicizes a page
Big gold purifier Beijing east the propagandist page of self-supporting flagship store has bit of exaggerated part, cause misdirect easily to consumer. Qiu Zhenjun suggests, will purify formaldehyde with KJ421F-N01 of this big gold likelihood effect is general, especially bridal chamber resident, buy want discretion.
Report of the F-VXG70C below the pine is analyticalDetect report part is chosen
The grain content CADR of the F-VXG70C below the pine achieves 402.8m3/h, than nominal tall many, but if consider noise again, in pine of not difficult discovery leaves the property of F-VXG70C and imagining so conspicuous.
Besides, the formaldehyde CADR of the F-VXG70C below the pine is nominal 50.1m3/h, but actual measurement result has 30.1m3/h only, difference is bigger still. Although divide the strong point that formaldehyde is not air purifier, but the tagging of function or need are more a few more rigorous. The difference of CADR of actual measurement formaldehyde may be the individual difference of the sample that we buy, so we think the F-VXG70C below the pine has the suspicion of empty mark.
So we see, these big plants purify performance side to be done so that return insufficient intention in formaldehyde, empty mark parameter calculated, real property part of be not a patch on hundreds of air purifier, it is image of brand having damage really.
Everybody also sees, basic the budget of 2000+ purifies airy demand with respect to can contented daily family, but still have many person hope choose and buys more high-end air purifier, fly for instance benefit riverside, Dai Sen such old brand.
