Determining the optimal time to replace HEPA or ULPA filters in cleanrooms should not be based on calendar schedules, but rather on condition-based monitoring using pressure differential (measured in Pascals, Pa). Replacing filters too early wastes budget, while replacing them too late compromises airflow velocity and production yield. The standard procedure involves recording the "initial resistance" (pressure drop) when new filters are installed at proper airflow (e.g., 0.45 m/s). Filters should generally be replaced when the pressure differential reaches twice (2x) the initial resistance, or immediately if the Fan Filter Unit (FFU) can no longer maintain required airflow velocities even at maximum power. Deshengxin Purification Equipment Co., Ltd., as a full-industry chain manufacturer, ensures consistent initial resistance specs, making predictive maintenance accurate.
