HEPA and ULPA Filter Integrity Testing in the Triangle

Triangle Cleanroom Pros provides certified HEPA and ULPA filter integrity testing, leak detection, and airflow verification for controlled environments across Raleigh, Durham, Chapel Hill, Cary, Apex, and Morrisville. Our technicians use calibrated aerosol photometers, scan probes, and ISO 14644 compliant testing methods to ensure your cleanroom’s filters perform at required efficiency levels to maintain contamination control.

Whether you need routine annual integrity testing, post-maintenance validation, or emergency leak investigation, our team delivers fast, accurate, fully documented testing with clear pass/fail results and recommendations.

Leak Detection & Scan Testing

Our scan testing process locates any filter leaks, media defects, gasket failures, or installation issues. Using industry-standard PAO aerosol challenges and calibrated photometers, we inspect the full surface of each filter, frame, and seal to verify proper containment and airflow.

Aerosol Challenge & Efficiency Verification

We introduce a controlled PAO aerosol upstream, then verify downstream penetration to ensure the filter meets ISO, CETA, and manufacturer specifications. This confirms overall filtration performance and ensures your system maintains proper cleanliness classifications.

Airflow & Differential Pressure Checks

Proper airflow and static pressure are essential to HEPA performance. Our team measures velocity, verifies directional airflow, and checks pressure differentials across critical spaces to ensure each room maintains stable environmental control.

Filter & Seal Condition Assessment

We assess media condition, frame integrity, gasket compression, and installation quality. If performance issues are detected, we provide guidance on replacements, resealing, or corrective actions required for compliance.

HEPA Recertification & Audit Preparation

We support annual or semi-annual recertification cycles and provide documentation needed for internal audits, FDA inspections, USP 797/800 compliance, and ISO 14644 classifications.
