The Importance of air filter maintenance in laboratory ventilation systems – Preserving Containment Integrity, Operational Safety, and Regulatory Compliance
Executive Summary Filtration is the primary defense in laboratory ventilation systems, particularly in biosafety level 2 (BSL-2) and biosafety level 3 (BSL-3) environments where airborne biological hazards may be present. Prefilters and secondary filters are essential for capturing particulate matter, preventing environmental contamination, and preserving the efficiency and integrity of high-efficiency particulate air (HEPA) filters.
