In order to prevent smog, many people have bought air purifiers in their homes, and some homes have more than one. Sales of air purifiers in Europe reached 5.2 million units last year and are expected to double this year, according to statistics. Air purifiers will become the fifth largest household appliance after color TVS, air conditioners, refrigerators and washing machines. There are nearly a thousand brands in this huge market, but what about their quality?
Today, the provincial Quality supervision Bureau released the air purifier product quality and safety risk monitoring, from the market to buy extraction of 15 enterprises produced by the air purifier testing found that there are only three standards.
Liu Mengmeng, an engineer at the home product testing center of the Provincial Quality Inspection Institute, told reporters: “The risk monitoring, there is a widespread phenomenon of exaggerated publicity, mainly in noise, clean energy efficiency, and the sterilizing rate of these three indicators.”
The risk points found are mainly particulate matter clean air quantity, formaldehyde purification energy efficiency, particulate matter purification energy efficiency, antibacterial rate and noise. Among them, there were 5 air purifiers with antibacterial function, but the coincidence rate of antibacterial rate was 0%.
Liu Mengmeng introduced to reporters: “Air purifier products there is a very important core indicators is the cumulative amount of clean, we compared the mesh of air purifier ChengHaiMian, purification increases with time, the adsorption of sponge pollution increase, so this time we will regularly change the sponge, so clean air quantity, namely CCM value is also means the greater the adsorption capacity of the sponge, It also means that the air purifier filters last longer and are replaced less often.”
Some air purifiers excessively promote the purification effect, especially the virtual standard of clean air quantity, resulting in consumers failed to replace the filter in time, not only can not effectively purify THE PM2.5 particles, formaldehyde, bacteria and other indoor, but also will produce secondary pollution, harmful to human health.
At present, air purifier products in addition to the existence of exaggerated publicity of the purification effect of the problem, the provincial quality supervision department also found that some air purifier air outlet size is too large, children’s fingers can be inserted, there is a potential safety hazard of electric shock or stir fingers.
Household air purifier is mainly based on filter purification, which is to pump air into the machine with a fan and filter the pollutants in the air through the built-in filter.
Olansi Healthcare Co.Ltd. Air purifier manager Joanna illustrates the working principle of air purifier to the reporter, she said: “we are now on to make a pollution environment, then we use the cell phone QPP, to control our purifier boot, about 10 seconds, we can see that the smoke has been to remove completely.”
At present, the particle purification technology is relatively mature, can well remove PM2.5 and other pollution particles in the air.
“But in the risk monitoring, we found some problems with the air purifier. The gap between the air purifiers is too large, similar to that of children or adults with small hands, which may encounter live parts or moving parts that day,” said Joanna.
