General service life range of flat air filter
General service life range of flat air filterUnder ideal conditions of use, that is, the use of ambient air quality is good, the dust concentration is low, the humidity is moderate, and the use frequency and air volume are within the rated range of the filter, the service life of the flat air filter is usually about 6 months to 1 year. This range of life is suitable for primary and mid-effect flat air filters in most general ventilation and air conditioning systems.The initial effect of the flat air filter, its main function is to filter the larger particles of dust in the air, such as hair, catkins, large particles of dust, and so on. Due to its relatively low filtration accuracy and limited dust capacity, the service life is mostly 3-6 months in the general indoor environment. For example, in the air conditioning system of ordinary families, if the air quality of the area is good, there is no obvious industrial pollution and a large amount of dust, the initial effect of the flat air filter can be used for about 6 months; however, if the living environment is near a dusty place such as a construction site or road, it may need to be replaced within three months. The filtration accuracy of the medium effect flat air filter is higher than that of the primary effect filter, which can filter finer particles, such as pollen, bacteria, smoke particles, etc. In normal office places, shopping malls, and other environments, the service life of medium-efficiency flat air filters is generally 6-12 months. Take ordinary office buildings as an example, the medium efficiency filter in the ventilation system, if properly maintained, can be replaced once a year to meet the use requirements; However, in some places with high air quality requirements and large personnel flow, such as the outpatient hall of a hospital, due to the relatively high content of microorganisms such as bacteria and viruses in the air, and more dust particles, the medium-effect filter may need to be replaced every 6 months. However, it should be emphasized that this is only a general service life range, and the actual service life will vary due to the various factors described above. In some special harsh environments, the life of flat air filters may be greatly shortened, or even only a few weeks; In an extremely clean environment, its service life may be extended to more than 1 year. |
