Cleanroom Testing & Certification

There’s nothing more important to the operation of a cleanroom than proper certification. Your cleanroom must meet testing requirements for your specific ISO Class level before you can begin production. 


Modulus Cleanrooms is dedicated to delivering the cleanroom you need, and we stand behind each of our cleanrooms with quality testing, certification, and cleanroom validation. 


We provide cleanroom testing and certification for clients looking into renovating or updating existing cleanrooms and certify each of our new cleanrooms with quality cleanroom testing completed by a reputable third party.

Cleanroom Certification

Cleanroom certification is crucial to the success of your production. It’s a service that Modulus Cleanrooms takes very seriously. Every Modulus Cleanroom is designed and built to meet your required cleanroom ISO standards. 

When construction is complete, your cleanroom will be tested and certified by an independent third-party to ensure it meets your required cleanliness levels.
