OEM vs 3rd party HEPA filter real-world airflow (CFM) restriction test
Executive Summary OEM filters are precision-engineered to match a purifier’s static pressure and motor torque, ensuring optimal airflow (CFM) and long-term motor health. Third-party HEPA filters frequently introduce airflow restrictions that degrade PM2.5 and VOC sensor accuracy, corrupting smart automation logic. Skewed pressure-drop data caused by non-OEM media can trigger premature filter-replacement alerts and falsify … Read more
