Cleanroom Certification in New York, NY

The New York metro carries one of the country's densest concentrations of hospital and healthcare systems, alongside major pharmaceutical operations and financial-sector data center infrastructure. GENTAB certifies cleanrooms and controlled environments across the region to ISO 14644 standards, supporting operating rooms, sterile compounding pharmacies, and critical care environments as well as pharmaceutical and industrial cleanrooms.

We verify airborne cleanliness through particle measurement, scan HEPA filtration for integrity, confirm air change rates, and map the pressure relationships that keep sterile spaces protected, then deliver documentation suitable for internal review and accreditation activity. Our teams support new-space certification, post-renovation requalification, and routine recertification for facilities across the metro.

Airborne Particle Classification: Particle count measurement and statistical analysis to determine and document ISO 14644-1 cleanliness classification at rest and in operation.

HEPA / ULPA Filter Integrity Testing: Aerosol challenge (PAO) scanning of installed filters and housings to detect leaks, bypass, and media damage before they compromise the space.

Air Change Rate & Recovery: Supply airflow measurement, air change rate calculation, and recovery testing to confirm the room clears contamination within its required time.

Room Pressurization Verification: Differential pressure mapping across doors and adjacencies to confirm correct cascade and protect critical spaces from cross-contamination.

Airflow Visualization & Uniformity: Smoke studies and velocity uniformity testing for unidirectional flow zones, documenting that airflow patterns sweep contaminants as designed.

Certification Documentation: A complete, audit-ready certification package referencing test methods, instrumentation, acceptance criteria, and pass/fail results per room.
