说说节能的问题了，既然是商用空气净化器，肯定会经常处于运行状态，电费问题不容小觑。好多用户买了空气净化器却因为耗电厉害，让净化器成了摆设
Let's talk about energy conservation. Since it's a commercial air purifier, it's bound to be in operation frequently. The problem of electricity bills cannot be underestimated. Many users bought air purifiers, but because of the high power consumption, the purifiers became a decoration
就是要看产品的人性化设计方面的东西了，比如滤网问题，专家提醒消费者，空气净化器如果长时间不清洁滤网，也会成为滋生细菌的温床。而现在市面上的大部分空气净化器的滤网都包在产品外壳内，无法有效判断是否该更换清洗，而滤网最好经常更换，即使在空气质量较好的情况下也不能超过半年，否则滤材吸附饱和之后会释放有害物质，变成“污染源”。
It depends on the humanized design of the product, such as the problem of filter screen. Experts remind consumers that if the air purifier does not clean the filter screen for a long time, it will also become a hotbed for bacteria. However, most of the filters of air purifiers on the market are packed in the product shell, so it is impossible to judge whether to replace and clean them effectively. It is better to replace the filters frequently, even if the air quality is good, it can not exceed half a year, otherwise the filter material will release harmful substances after adsorption and saturation, and become a "pollution source".
