What is the service life of the primary filter and medium filter?
What is the service life of the primary filter and medium filter?The service life of the primary filter and medium filter is affected by many factors. Generally:Primary filter: In a normal working environment, the service life of the primary filter is usually 1 to 3 months. If the working environment has relatively less dust pollution and good air quality, its service life may be extended; conversely, if the working environment has more dust, the service life of the primary filter will be shortened accordingly, and it may need to be replaced frequently. For example, in office areas with good air quality, the primary filter may be replaced once every 3 months; while in some places with high dust concentrations such as factory workshops, it may need to be replaced once a month or even shorter. The filter material of some primary filters can be washed and can continue to be used after washing. The service life of such washable primary filters is relatively long, but the number of washings should not be too many. Usually, it needs to be replaced after one or two washings. Medium filter: Its service life is generally 3 to 6 months. If the use environment is relatively clean and the air dust content is low, the maintenance cycle of the medium efficiency filter may be about 6 months; but if it is in an environment with more dust and heavy pollution, the maintenance cycle may be shortened to 3 months or even shorter. It should be noted that the above is only an approximate service life range. In actual use, the replacement time should be comprehensively judged based on factors such as the specific use environment, maintenance conditions, and filter performance changes. Regularly check the filter's pressure difference, filtration efficiency, and other indicators. When the filter performance is found to be significantly reduced or cannot meet the use requirements, it should be replaced in time. |
