Despite the declining popularity of the air-purifying market this year, no one will deny that it will have a huge room for growth in the future, and the reputation of this appliance industry is obvious to all. Therefore, new arrivals are in an endless stream in early 2017. Gree and Midea, Sharp, Matsushita and other traditional home appliance giants into the game last year, there are Netease strict selection, ink weather, a large number of hammer and other Internet companies cross-border air purification industry 'shareware.'
More and more players at the same time, the state regulation and control of the empty net market is also continuing to strengthen.Recently, Shanghai Quality and Technical Supervision on the basis of expert assessment, commissioned the Shanghai Institute of Measurement and Testing of local production and sales Part of the air purifier products were sampled.
Among them, the test is an important area - the applicable area index, as an important indicator of purification of air purifier products, there is no national standard requirements.It is understood that the applicable area refers to the maximum indoor air purifier suitable for use, The unit is square meters (square meters), which is simply calculated by multiplying the nominal amount of particulate clean air (CADR) on the product by 0.1, causing many merchants in the market to exaggerate the performance of products and mislead consumers in order to sell their products Phenomenon.Examination results show that some big-name appliance companies such as Daikin, Pentium, etc. can not be avoided, in addition, there are many products that have not been the nominal area, or not the nominal amount of particulate clean air.

In this test, many plowed net industry for many years, corporate performance dazzling performance, such as Samsung, 3M, Sharp, Darth, both in the amount of clean air particles or in the application area of the detection link, there are excellent Performance in recent years, the United States newly recruited air purifier also performed well, in a number of professional testing areas in the top rankings.
In other project testing, such as Tamatsu and other brands appear formaldehyde purification efficiency is too low.Formaldehyde purification efficiency is the air purifier operating nominal nominal area conditions, after 1 hour of operation, the removal efficiency of formaldehyde, through specific Simulation test results obtained under the conditions of the product and the nominal conditions of use (ie, applicable area) and the ability of gaseous pollutants are closely linked, that is, formaldehyde purification efficiency is too low will affect the use of the air purifier scene.

Here to remind everyone, according to their actual needs to buy air purifier, is not multi-function, big brand will certainly be good, not only to choose more specialized products, but also for their own .As haze multiple areas can focus on the PM2. 5 and other particles purification ability of products, interior decoration can focus on formaldehyde and toluene and other volatile organic compounds purification ability of products.
Of course, but also concerned about the air purifier particulate clean air volume (CADR) and the applicable area, the two is proportional to the conversion formula is: Applicable area = CADR × 0.1. Each air purifier should have the recommended area and The measured CADR. Air purifier CADR value greater, on behalf of the same environmental conditions, the stronger the purification capacity, purification faster.
At the same time, the purchase of air purifiers, but also require manufacturers to provide third-party inspection agencies test reports to confirm the measured values of the indicators, test methods and product promotion match.
Following the introduction of the new national standard in March 2016, as of October the same year out of more than 100 substandard brands, the 2017 National Household Electrical Standardization Technical Committee has also begun to promote the purifier core components of the standard formulation, at present, "air purification Filter with filter "," electrostatic dust filter with air purifier "two industry standards have entered the final stage is expected to be formally introduced this year after the implementation of these two major industry standards, we will provide more intuitive reference , Further regulate the air purifier market.
