In recent years, people's requirements for quality of life have been continuously improved. In the context of the PM2.5 era, air purifiers have naturally become the new darling of consumers. However, in the selection process, various standards and professional terms have become the choice of high-quality air purifiers, and the sales and advertisements of the products and merchants are so lost that consumers lose their way in the purchase.
Recently, the Shanghai Consumer Protection Committee released the latest air purifier comparison test results. Initiated a new round of discussions on air purifier standards. What are the mysteries, what kind of air purifier can be considered high quality, let's take a look at it.
Five big data to easily solve the selection problem
The results of the comparative test of air purifiers notified by the Shanghai Consumer Protection Committee are related to five criteria. They are clean air output ratio (CADR), energy efficiency rating, PM2.5 purification efficiency, formaldehyde purification efficiency and applicable area.
Net Air Output Ratio (CADR): The Clean Air Output Ratio (CADR) is the ratio of air purifier output clean air from the American Society of Home Appliance Manufacturers (AHAM) tests conducted in accordance with rigorous testing standards. The following indicators are comprehensively measured: particle size removal, filtration efficiency, and number of air changes. The higher the CADR value, the higher the purification efficiency of the air purifier. The performance of the air purifier is mainly determined by the clean air output ratio (CADR value). The higher the clean air output ratio, the higher the purification efficiency of the purifier. Therefore, it can be known that the CADR value is an important value that cannot be ignored.
Energy efficiency rating: The energy efficiency rating of the air purifier is divided into five levels according to the energy efficiency ratio. An air purifier with an energy efficiency ratio of 6.00 cubic meters per watt hour or more has an energy efficiency rating of one level and is the best. If the energy efficiency ratio is less than 2.5 cubic meters per watt hour, it will not be qualified.
PM2.5 purification efficiency, formaldehyde purification efficiency and applicable area: It is not difficult for consumers to understand, and can make correct judgments with daily life experience. Applicable area is a relative value, consumers can decide according to their specific circumstances, enough, and there is no relevant standard that the air purifier with a large area is good. Many consumers tend to pay too much attention to the applicable area and ignore the Clean Air Output Ratio (CADR). In comparison, the Clean Air Output Ratio (CADR) is the most important indicator.
Blueair air purifiers are the best in their class
From the comparison results of air purifiers, Blueair air purifiers and Amway air purifiers are in a leading position, and their comprehensive performance far exceeds that of other brands of the same grade.
Both PM2.5 purification efficiencies are greater than 99%; for formaldehyde purification efficiency, Blueair is 97% and Amway is 76%. In today's situation where PM2.5 and formaldehyde are so valued, these two points are particularly important. Blueair's purification efficiency and CARD value are outstanding in the same price air purifier, and it has always been the leader in high-end air purifiers. status.
Balance of Blueair performance
There are currently three main types of air purifiers on the market, namely mechanical filters, electronic air cleaners (also known as electrostatic filters) and ionizers. Blueair's HEPASilentTM technology combines the strengths of both mechanical and electrostatic filtration. Compared to traditional mechanical filtration systems, the HEPASilentTM high-efficiency filtration system delivers clean air with low noise, low energy consumption and high efficiency, balancing performance.
Relying on the HEPASilentTM high-efficiency filtration system, the Blueair air purifier can filter air particles as small as 0.1 micron; the efficiency of filtering exhaust gas, soot and some germs is 99.97%; and the replacement rate in the standard use space is higher, which can effectively cope with continuous pollution. freed.
The enclosed ion chamber and low current ionizer ensure that the Blueair air purifier does not generate excess ozone and removes ozone from the room. The ultra-quiet motor fan, metal housing and sound-absorbing layer make the product truly quiet. At the same time, Blueair is the first brand of air purification equipment certified by ENERGY STAR. The electricity bill for using the Blueair air purifier is equivalent to using a small light bulb.
While the Shanghai Consumer Rights Protection Committee notified the air purifiers to compare the test results, it also put forward some suggestions for consumers to refer to when purchasing goods: (1) to purchase more targeted air according to their actual needs. Purifiers, air purifiers have a big difference in brand, function, performance, design, and price. (2) It is best to keep the doors and windows closed during normal use, to avoid a large amount of indoor and outdoor air interflow, resulting in a decrease in purification effect. (3) At the beginning of the air purifier opening operation, it is recommended to run in the high wind volume for at least 30 minutes to achieve the effect of rapid air purification. (4) Before the air purifier that has not been used for a long time is turned on again, check the cleanliness of the inner wall of the machine and the state of the filter.
