Now the filter element replacement function is all countdown function, which has nothing to do with whether it is clean or not. The manufacturer recommends that the activated carbon filter screen be replaced every half a year, which is a recommended time, because the toxic gas pollution caused by the decoration of each household is completely different. Some may exceed the standard by several times, more than ten times, or even dozens of times, while some may be within the standard range. Users can take it out and smell it after using it for a period of time (half a year is recommended): the saturated filter screen smells bad. When you smell bad smell, you should change the filter screen to ensure the health of yourself and your family. The purifier usually placed in the living room is easy to be dirty due to the large amount of dust, but the activated carbon net may not absorb much toxic odor. However, since the environment of the purifier in the bedroom is relatively sealed, the HEPA net may be cleaner than that in the living room, while the activated carbon net is dirtier than that in the living room. So the replacement time varies from person to person. For example, if you smoke, because the smoke is particulate matter, it will adhere to the filter element. After a period of time, as long as you turn on the purifier, you will smell the odor. So maybe you need to change the filter element in a month. At the same time, it is necessary to regularly clean the filter screen of the outermost shell, which is responsible for adsorbing large dust and easily blocking the suction port.
