How often is the filter material of the air filter box replaced?
How often is the filter material of the air filter box replaced?The replacement cycle of the filter material of the air filter box is affected by many factors such as the use environment, the use time, and the type of filter material. The following is the description of the replacement cycle under normal circumstances:Classified by the use environment Family environment Ordinary urban environment: If the family is located in an ordinary urban area, there is no serious industrial pollution or road dust around, and the primary filter material of the air filter box is generally replaced every 3-6 months; Medium efficiency filter material can be replaced once every 6-12 months; If equipped with efficient filtration materials, it is usually replaced once every 12-24 months. Close to the pollution source environment: if the family is close to the factory, the main traffic road the construction site, etc., due to the high content of dust, particulate matter, and harmful gases in the air, the primary filter material may need to be replaced once every 1-3 months, the medium filter material is replaced in 3-6 months, and the efficient filter material is replaced in 6-12 months. Industrial and business environment Office, shopping malls, and other environments: In this kind of place personnel flow is relatively large, but the air quality is generally better than in the industrial environment, the initial effect filter material is generally replaced once every 2-4 months, the medium effect filter material is replaced 4-8 months, and the efficient filter material is replaced 8-16 months depending on the specific situation. Electronics factories, pharmaceutical factories, and other cleanliness requirements of the environment: to ensure product quality, the initial effect filter material may need to be replaced in 1-2 months, the medium effect filter material 2-4 months to replace, efficient filter material 4-10 months to replace. Classification by time of use Short daily use time: If the air filter box is used for less than 4 hours a day, in the ordinary environment, the primary filter material can be replaced in 4-6 months, and the medium filter material can be replaced in 6-12 months, and the high-efficiency filter material can be replaced in 12-24 months. Use for a long time every day: if the air filter box is used for more than 8 hours a day or even 24 hours of continuous operation, the primary filter material may need to be replaced in 2-3 months, the medium filter material will need to be replaced in 3-6 months, and the high-efficiency filter material will need to be replaced in 6-12 months. Classification by filter material type Primary filter materials: usually non-woven fabrics, metal mesh, and other main materials, mainly filter large particles of dust and hair, etc., in the general environment, the use of 3-6 months may affect the filtration effect due to blockage, and need to be replaced in time. Medium efficiency filter materials: common glass fiber, synthetic fiber, etc., for filtering smaller particle size particles, generally 6-12 months to replace, but in harsh environments or high load use, may need to be replaced in advance to 3-6 months. High-efficiency filter materials: such as high-efficiency filter paper, activated carbon composite filter, etc., can filter smaller particles and harmful gases, the replacement cycle is relatively long, generally 12-24 months, but if used in high-pollution environments or places with extremely high air quality requirements, it may need to be replaced in 6-12 months. Activated carbon filter material: The adsorption capacity of activated carbon will gradually saturate with the use of time, generally 3-6 months need to be replaced to ensure the removal of harmful gases and odors. In actual use, it is recommended to check the pollution level of the filter material regularly to determine whether it needs to be replaced. If it is found that the surface of the filter material is blackened and blocked, or the air output volume of the air filter box is significantly reduced, and the noise is increased, etc., even if the above-recommended replacement cycle is not reached, the filter material should be replaced in time. |
