The regular replacement cycle for the HEPA filters in the ultra-clean workstation: 1 to 3 years. The cycle varies greatly depending on the specific scenario. I will clearly explain it to you by industry to facilitate your record-keeping or SOP creation.
\nI. General Universal Cycle
\nGeneral laboratories and electronic workshops: Replace once every 2 to 3 years
\nHigh dust levels in the environment and frequent use: Replace every 1 to 2 years
\nClean environment and low usage frequency: Can be up to 3 years
\nII. More Precise Reference by Industry
\nOrdinary teaching \/ research laboratories: 24 to 36 months
\nFood, cosmetics clean workshops: 18 to 24 months
\nPharmaceutical factories, GMP sterile rooms, biosafety laboratories: 12 to 24 months
\n(Many enterprises directly replace once a year to avoid audit risks)
\nIII. Key Factors Affecting Replacement Cycle
\nWhether the primary filter is cleaned \/ replaced on time
\nIf the primary filter gets dirty and is not dealt with, the efficiency will clog very quickly, and the lifespan will be halved.
\nDust level in the environment
\nIf there are grinding, crushing, mixing, dust-producing processes nearby \u2192 The lifespan of the efficiency will be significantly shortened.
\nDaily operating time
\n24-hour operation vs. 2 hours per day, the lifespan is more than double.
\nWhether there are corrosive gases
\nWill corrode the filter paper, leading to premature failure.
\nIV. The Most Reliable Practice in Practical Work
\nNot just relying on time, use “time + wind speed” for dual determination:
\nFirst, set the cycle at 1 to 3 years
\nAs long as the wind speed is lower than 0.25 m\/s or the cleanliness does not meet the standard
\n\u2192 Replace immediately, no need to wait for the expiration date
\nV. Summary in One Sentence
\nGeneral scenarios: 2 to 3 years; Pharmaceutical GMP: 1 to 2 years; Replace early if the wind speed is insufficient.<\/p>","protected":false},"excerpt":{"rendered":"
