HEPA/ULPA Filter Integrity Test

HEPA/ULPA Filter Integrity Test ensures the effectiveness of high-efficiency filters in cleanrooms and controlled environments. It detects leaks and defects, verifying filter performance and preventing contamination. This test is critical in industries like pharmaceuticals, biotechnology, and healthcare. Ensures product quality and personnel safety.

The HEPA/ULPA Filter Integrity test verifies the integrity and performance of High Efficiency Particulate Air (HEPA) and Ultra-Low Penetration Air (ULPA) filters, ensuring they meet the required standards for particle removal and contamination control.

• DOP/Solvent test: A challenge aerosol is introduced upstream of the filter, and a detector measures the downstream concentration to determine filter efficiency.
• Particle scan test: A particle counter scans the filter face and downstream side to detect any leaks or defects.
• Scan testing: The entire filter face is scanned to identify any pinhole leaks or defects.

• Ensures contamination control: Verifies that HEPA/ULPA filters are functioning correctly to protect products and personnel.
• Meets regulatory standards: Complies with standards and guidelines for cleanrooms and controlled environments.
• Prevents product loss: Identifies filter defects or leaks that could compromise product quality.
• Optimizes filter replacement: Helps determine when filters need to be replaced.

The HEPA/ULPA Filter Integrity test is typically performed by trained professionals, such as:

• Validation engineers
• Cleanroom experts
• HVAC specialists

• Cleanrooms: Verifying HEPA/ULPA filter integrity to maintain cleanroom classification.
• Pharmaceuticals: Ensuring filter integrity to protect products and personnel.
• Biotechnology: Protecting sensitive biological materials from contamination.
• Laboratories: Maintaining controlled environments for research and testing.

By performing HEPA/ULPA Filter Integrity tests, facilities can ensure that their filters are functioning correctly, protecting products and personnel from contamination.
