Why is it necessary to perform an NSF test after replacing the filter?｜READY 

Biological Safety Cabinets (BSCs) are critical laboratory equipment designed to protect personnel, products, and the environment when handling biological materials.
HEPA filters play a key role in maintaining containment performance.
After filter replacement, performance verification is essential to ensure the cabinet continues to meet safety standards.
