一：没有雾霾就不开
　　A: no haze will not open
　　冬季室内通风不畅，油烟、灰尘等引起的污染，有时比室外还要严重。所以在冬季没有雾霾的情况下，室内也应多用净化设备。
　　Winter indoor ventilation is not smooth, soot, dust and other pollution caused, sometimes more severe than outdoor. Therefore, in winter there is no fog and haze, indoor should also use　purification equipment.
　　二：只要使用就管用
　　Two: as long as the use will work
　　在室内使用空气净化设备，首先应该尽可能减少污染源，不在室内吸烟。在空气良好的时候保持室内通风，空气污染严重时要少开窗。这种情况下使用空气净化设备才有良好的效果。如果认为室内开了净化设备，不管外面空气多糟糕，仍然频繁开关窗，净化设备不会起到好的作用。
　　Indoor use of air cleaning equipment, first of all, should minimize the pollution sources, not smoke indoors. Keep ventilation indoors when the air is good. Open windows when air pollution is serious. In this case, the use of air purification equipment will have a good effect. If the indoor cleaning equipment is opened, no matter how bad the outside air is, it is still frequent switching windows, cleaning equipment will not play a good role.
　　三：不清洁更换滤网
　　Three: not clean, replace the filter
　　空气净化设备的耗材是滤网，而且更换滤网的价格比较高。如果空气质量差，滤网的使用寿命还会降低。为了节约，不少人在滤网的更换上并不及时，甚至认为买了空气净化设备可以一劳永逸，忽略了日常的清洗和维护，往往造成室内二次污染。空气净化设备应该进行定期清洁。当打开机器发现滤网变黑，或是感觉吹出来的空气已经有异味，就必须得更换滤网了。
　　The biggest material for air cleaning equipment is the filter screen, and the price of the replacement filter is relatively high. If the air quality is poor, the service life of the filter will be reduced. In order to save, many people in the filter replacement is not in time, even think that buy air purification equipment can once and for all, ignore the daily cleaning and maintenance, often cause indoor two pollution. Air cleaning equipment should be cleaned regularly. When the machine is opened, the filter screen is black, or the air is out of smell, the filter must be replaced.
