The selection of filtering materials in high-efficiency air filters with a small area or a small dust capacity per unit area can affect the service life of the filter. When designing, it is necessary to consider that the area of the filtering material in the high-efficiency air filter is too small or the dust absorption per unit area is too small. A high-efficiency air filter with a large area can greatly extend its service life.
If the project is completed, replacing the old filtration system to extend its service life can be very troublesome. In many projects, users need to minimize the space occupied by the air conditioning system as much as possible, or they may not have noticed that the supplier used cheap filters with small filter areas during the price reduction process. Although the filter can meet the requirements of air purification during project acceptance, the service life of the filter will not be very long due to the small area of the filter material.
If the selected high-efficiency air filter has low filtration efficiency, it will also affect its service life. Therefore, the filtration efficiency of the high-efficiency air filter can be adjusted to prevent dust from entering the high-efficiency air filter. For example, if the filter is F7, then when using G4 high-efficiency air filter, its lifespan is 3 months. After replacing with F5 high-efficiency air filter, its service life can be extended to six months.
In a clean room, the value of high-efficiency filters that terminate their lifespan is not high, but the risk and indirect cost of replacing the filter will be high. Replacing the pre filter does not require stopping production, so experienced owners will pay attention to and spend money on the filter. The service life of the main filter depends on the quality of the previous high-efficiency air filter.
Each device has its own lifespan, so users have high expectations for the lifespan of high-efficiency air filters.
