Yesterday, Weibo netizen "Mark Hehehe" sent Weibo to express doubts about its own air purifier: "It was discovered today that the plastic packaging of the filter element has not been torn open. Before that, the indicator of air quality can also change from red to green. What do you do? How does the filter consumption displayed in the APP work?" Originally, the Xiaomi air purifier purchased by "Mark Hehehe" has not removed the packaging film of the filter element due to mistakes in use. Surprisingly, after the purifier is still working for a period of time, the indicator light shows that the air inside the house has been purified to a healthy standard. After this microblog was forwarded by the famous counterfeiter Wang Hai, public opinion spread rapidly. In response to the situation reflected in "Mark Hehehe", the reporter found three millet purifiers for simulation experiments. Among the three purifiers, one is the millet generation and the other is the millet second generation. The reporter took out the three purifier filter elements and wrapped the whole filter element firmly with the fresh-keeping bag and cling film to simulate the plastic packaging of the new filter element that was needed when “Mark Hehehe†was unopened. After that, put one Xiaomi second-generation purifier in one room and the other two purifiers in another room. When the reporter reloaded the packaged filter into the purifier and turned it on, the three purifiers showed serious indoor air pollution and illuminated orange-red lights. One hour later, a separate millet second-generation purifier still kept the orange-red display light, while in the other two purifiers placed side by side in the room, the millet second generation is still the orange-red indicator, the first generation purifier is It turned into a green light soon after the boot. Last night, Su Jun, the person in charge of Xiaomi Air Purifier, responded by Weibo that there is still a filter cartridge consumption when the filter plastic package is not disassembled, because the filter consumption is based on the predictive judgment of the purifier running time and state. Even if the plastic seal is not removed, the filter cartridge will be consumed by default. For the indicator light from a red light that shows serious pollution to a good green light, Su Jun explained that because even if the plastic film is not removed, the ambient air quality detected by the sensor will change due to particulate sedimentation and local air flow. However, this reply obviously does not answer people's doubts. The netizen "Mark Hehehe" concerns and questions about the air purifier filter element actually reflects the confusion of many citizens. What are the most important criteria to consider when purchasing an air purifier? When is the filter changer in the end who has the final say? In response to the hot issue of air purifiers in the market, the reporter interviewed relevant experts and senior practitioners, and sorted out several suggestions on the purchase and use of air purifiers. Recommendation one: Technology gimmicks Look at the two indicators when you buy Plasmacluster air purification technology, humidifying air purifier, seven-layer purification... Search for air purifiers on e-commerce websites such as Jingdong and Tmall, and each brand has come up with its own “housekeeping technologyâ€. Dazzling. "We are doing air purifiers here, the pm2.5 removal rate is 99%! Consider it!" In an electrical appliance store, salespeople rushed to the people who came to buy haze. However, Lu Jianguo, deputy director of the China Household Appliances Testing Institute, suggested that “you don’t have to look at those virtual ones. Just look at the two core standards when you buy. One is the 'clean air volume', which is the CADR value, and the second is’ Cumulative purification amount, CMM value." According to Lu Jianguo, according to the latest national standard for air purifiers, these two parameters measure the ability of an air purifier to purify air and the sustainability of purification. When the CADR value is larger, the ability of the air purifier is stronger; the larger the CMM value, the greater the endurance and the longer the use time. Simply put, the larger the value of these two parameters, the better the effect of the air purifier.
