Many households have opened air purifiers in the haze. Yang Lu, a person in the appliance repair industry in Tianjin, suggested that after the weather improves, the relevant parts and parts of the air purifier should be cleaned and aired in order to prolong its service life. Continuously turning on the purifier will cause the filter to accumulate a lot of harmful substances. After the weather improves, the filter is the first to clean. At present, there are many kinds of filter screens used in air purifiers on the market, such as humidifying filter, activated carbon filter, and hepa filter. Some can be washed and some can't. It is recommended that the public read the instructions of the air purifier used and clean the filter as required. After that, the filter is placed in a ventilated environment to dry it, which can effectively remove the odor on the screen surface, so as not to affect the indoor air quality when used. The sensor window on the air purifier can detect the air quality in the room in time, and it is convenient for the user to select the operating mode of the machine. If there is dirt or dust around the sensor window, it will affect its sensitivity. The sensor window can be cleaned with a wet cotton swab and then dried with a dry cotton swab.
