Cleanroom testing and certification are crucial, and Modulus Cleanrooms takes both very seriously. We design and build our cleanrooms to ISO standards. Each individual cleanroom is tested and certified by an independent company to ensure it meets your required cleanroom cleanliness  levels.


Standard testing includes:

• Airflow Verification and Room and Air Changes per Hour​

• Filter Integrity (Leak Scan)             Testing​​

• Room Differential Pressure​

• Non-Viable Airborne Particle       Concentration​​

• Temp & RH Testing
