How to determine whether the paper separator filter needs to be replaced
How to determine whether the paper separator filter needs to be replacedYou can determine whether the paper separator filter needs to be replaced by the following aspects:Observation appearance Color change: Under normal circumstances, the new paper separator filter color is more white or the primary color of the material itself. After a period of use, if the surface of the filter is black and gray, and a lot of dust has accumulated, it indicates that it has absorbed more impurities, the filtration capacity may decline, and it needs to be replaced. Damage: Carefully check the paper partition and filter material of the filter, if there is obvious damage, tearing, or holes, it will cause the air to pass directly without filtering, affecting the filtration effect, and should be replaced immediately. Feel the effect of ventilation. Wind change: In the case of using the same fan power, if you feel that the wind of the outlet is significantly weakened, or the indoor ventilation effect is worse, it may be that the paper partition filter is blocked by dust, the air circulation resistance is increased, and the filter needs to be replaced to restore normal ventilation. Odor: When the filter absorbs a large amount of dust, bacteria, or other contaminants, it may produce an odor. If you smell a distinct odor during ventilation and rule out other possible sources of odor, then it is likely that the filter needs to be replaced. Reference service time: According to the use environment and type of paper separator filter, refer to its approximate service life. For example, in the ordinary family environment, the medium-efficiency paper partition filter is used for about 6-12 months, and the high-efficiency paper partition filter is used for about 3-8 months, even if the appearance and ventilation effect have not significantly changed, it is recommended to consider replacing it to ensure the filtration effect. With the help of professional instruments: you can use some professional air detection instruments, such as particle counters, anemometers, etc. By detecting the concentration of particulate matter in the air, the wind speed in the ventilation pipe, and other parameters, it can accurately determine whether the performance of the filter is reduced. If the test results show that the concentration of particulate matter in the air is significantly higher than normal, or the wind speed is lower than the design value, the filter may need to be replaced. |
