Clean Rooms – Frequently Asked Questions (FAQs)
General Questions
What is a clean room?
What industries use clean rooms?
How is cleanliness measured in clean rooms?
Design & Construction
What are the main components of a clean room?
Core components include:
- HEPA filtration systems
- Controlled airflow (laminar or turbulent)
- Cleanroom-grade walls, ceilings, and floors
- Gowning areas and airlocks
- Pressure differentials between zones
- Environmental monitoring systems
Can clean rooms be customised?
Yes. Clean rooms can be custom designed for class level, size, layout, HVAC performance, humidity control, and materials, depending on the intended application.
What is a modular clean room?
A modular clean room is a pre-engineered, scalable system built with prefabricated panels and components. It allows for faster installation, easier upgrades, and relocation if needed.
Operation & Maintenance
How are clean rooms kept clean?
Through controlled ventilation (HEPA filters), routine cleaning protocols, filter changes, gowning procedures for personnel, airlocks, and restricted access policies.
Do clean rooms require regular maintenance?
Yes. Regular maintenance includes filter changes, HVAC servicing, particle monitoring, surface cleaning, and periodic revalidation of air quality.
What clothing is required in a clean room?
Personnel typically wear gowns, gloves, face masks, hairnets, and shoe covers. Garment type depends on the clean room class.
How often should a clean room be validated?
Validation should occur at commissioning, after major changes, and periodically (typically annually or semi-annually) depending on regulatory and operational needs.
Cleanroom Classifications
What is the ISO classification system?
The ISO 14644-1 standard defines clean rooms by the allowable number of particles per cubic meter. Common classes include:
- ISO Class 5 (very clean – used in sterile pharma)
- ISO Class 7-8 (less stringent – used in general manufacturing)
What’s the difference between ISO Class 5 and Class 8?
ISO Class 5 allows far fewer particles than Class 8. For example, Class 5 permits 3,520 particles ≥0.5μm/m³, whereas Class 8 allows up to 3,520,000 particles of the same size.
Compliance & Certification
Are clean rooms required by law?
Clean rooms are often required by regulatory bodies for specific industries. For example:
- FDA (USA) for pharmaceuticals and medical devices
- EU GMP for drug manufacturing
- ISO 14644-1 for general classification and validation
Who certifies clean rooms?
Clean rooms are certified by third-party specialists following ISO, GMP, or industry-specific standards. Certification includes particle count testing, airflow validation, and pressure differential verification.
What happens if a clean room fails certification?
Corrective actions must be taken, such as cleaning, filter replacement, or HVAC adjustment. Revalidation is required before resuming sensitive operations.
Additional Considerations
Can a clean room be upgraded later?
Yes. Modular systems and scalable HVAC allow clean rooms to be upgraded to higher ISO classes or expanded in size.
What’s the difference between a softwall and a hardwall clean room?
- Softwall clean rooms use flexible curtains and are portable and cost-effective.
- Hardwall clean rooms use rigid panels, offering better environmental control and durability.
What environmental conditions can be controlled in a clean room?
Besides particle count, clean rooms often control:
- Temperature
- Humidity
- Pressure
- Lighting
- Noise
How much does a clean room cost?
Cost depends on size, ISO class, materials, HVAC needs, and industry-specific requirements. Basic modular systems start in the low five-figure range, while advanced, high-class clean rooms can exceed hundreds of thousands.
