FAQ
How often should a cleanroom be tested and certified?
According to international standards, it is recommended to conduct Cleanroom Testing at least once a year, or every 6 months for high-level cleanrooms (e.g., ISO Class 5 and above). Retesting is also required whenever HEPA filters are replaced or structural modifications are made to the room.
What is the NEBB standard, and why is it important?
NEBB (National Environmental Balancing Bureau) is a premier international association based in the USA that establishes standards for testing HVAC and cleanroom systems. Utilizing a NEBB-Certified firm guarantees the accuracy of the testing process and is globally recognized by Auditors.
