The normal service life of paper-frame high-efficiency filters is mostly between 6 and 12 months. In reality, there will be significant differences depending on the dirtiness of the usage environment. Here is a practical and commonly used reference range for you:
\n1. General service life reference
\nClean rooms, electronics factories, operating rooms, and pharmaceutical workshops have relatively clean environments and are protected by primary and intermediate filters \u2192 6 to 12 months
\nSpray workshops, woodworking workshops, cement plants, garbage stations, etc., with large amounts of dust and heavy oil stains \u2192 3 to 6 months, or even shorter
\nOffice buildings, shopping malls, and ordinary central air conditioning environments have medium levels of dust \u2192 9 to 12 months
\nHome \/ commercial air purifiers \u2192 8 to 12 months
\n2. Criteria for determining when to replace (more accurate than time)
\nGenerally, we do not strictly adhere to a fixed time. Look at these two points:
\nThe final resistance reaches about twice the initial resistance (usually when it reaches 400 to 450 Pa, it must be replaced)
\nThe air volume becomes significantly smaller, the air outlet is weak, or the cleanliness does not meet the standard
\nPaper-frame high-efficiency filters cannot be cleaned or reused. If clogged, it can only be replaced with a new one directly.
\n3. Key to extending the service life
\nThe primary and intermediate filters must be equipped for protection
\nThe primary filter is replaced every 1 to 3 months, and the intermediate filter every 3 to 6 months
\nAvoid high humidity, high temperature, and environments with water splashing, otherwise the paper frame will deform and leak air.<\/p>","protected":false},"excerpt":{"rendered":"
