How long is the life of a flat air filter?
How long is the life of a flat air filter?The life of a flat air filter is affected by a variety of factors, generally speaking, its service life ranges from 3 months to 2 years, the following is the specific analysis:Influencing factor Use environment Air quality: If the air quality in the environment is poor, such as in construction sites, mines, and other places with high dust concentrations, the filter will be clogged with dust faster, and the life may only be 3-6 months. In indoor environments with better air quality, such as some high-end office buildings, laboratories, etc., its life may be extended to 1-2 years. Environmental humidity: A high-humidity environment may cause the filter material in the filter to be damp, reduce the filtration effect, and even breed microorganisms, thus shortening the service life. Generally speaking, the relative humidity is maintained at more than 70% for a long time, which will shorten the filter life by about 20%-30%. Frequency of use Running time: If the air filtration system runs continuously for a long time, the flat air filter continues to be in the working state, the loss of its filter material will be accelerated, and the life will be shortened accordingly. For example, in some industrial production workshops that are open all year round, filters may need to be replaced every 6-9 months. Conversely, in less frequently used venues, such as seasonally used venues, their lifespan may be extended to 1-2 years. Ventilation: Large ventilation means that the amount of air passing through the filter per unit time is large, and the dust and other impurities intercepted by the filter are also large, which will accelerate the blockage and aging of the filter. When the ventilation volume exceeds 20% of the rated air volume of the filter, its life may be shortened by 30%-40%. Filter material Ordinary material: The use of ordinary glass fiber or synthetic fiber and other materials of flat air filter, the price is relatively low, but its filtration effect and durability are relatively poor, and the general life is 3-12 months. High-performance materials: Some flat-plate air filters using high-performance materials such as electrostatic filter material and activated carbon filter material not only have high filtration efficiency, but also have large dust capacity, which can maintain a good filtration effect for a long time, and the life may reach 1-2 years. Decision method In actual use, judging whether the flat air filter needs to be replaced can not only be based on time, but also need to combine the resistance change of the filter, filtration effect, and other factors. When the resistance of the filter reaches 2-3 times the initial resistance, or the air quality after the filter is not up to standard, even if the use time does not reach the above life range, the filter should be replaced in time to ensure the normal operation of the air filtration system and air quality. |
