In-depth answers to guide your cleanroom projects and decisions.
The highest grade of cleanroom is ISO Class 1, which allows the fewest particles per cubic meter of air. In pharmaceutical terms, the strictest level is Grade A, used for critical operations like sterile filling. These environments require advanced filtration, strict controls, and specialized protocols to maintain ultra-clean conditions.
Cleanroom classifications define how many particles are allowed in the air.
The two most common systems are:
ISO 14644-1 (International Standard): Ranges from ISO Class 1 (the cleanest, near particle-free) to ISO Class 9 (least strict). Each class specifies the maximum number of particles of a certain size per cubic meter of air.
EU GMP / FDA Grades (Pharma): Uses Grades A to D, with Grade A being the most sterile, typically for aseptic filling, and Grade D for less critical operations.
ISO 14644-1 defines cleanroom classes by the number of particles allowed per cubic meter of air. The lower the class number, the cleaner the air.
| ISO Class | Maximum Particles (≥0.5 μm per m³) | Typical Application |
|---|---|---|
| ISO 1 | 10 | Advanced nanotech, microelectronics |
| ISO 2 | 100 | Ultra-sensitive processes |
| ISO 3 | 1,000 | Aerospace, biotech R&D |
| ISO 4 | 10,000 | Semiconductor manufacturing |
| ISO 5 | 100,000 | Aseptic filling, pharmaceutical production |
| ISO 6 | 1,000,000 | Medical device assembly |
| ISO 7 | 352,000,000 | Pharmaceutical prep areas |
| ISO 8 | 3,520,000,000 | General clean manufacturing |
| ISO 9 | 35,200,000,000 | Controlled but less strict areas |
We supply ESD flooring, epoxy systems, vinyl, and raised floor panels—all durable, chemical-resistant, seamless, and designed for sterile, high-traffic environments.
Nupon cleanrooms support pharmaceuticals, biotechnology, electronics, semiconductors, automotive, food & beverage, chemical processing, healthcare, aerospace, and research laboratories.
Yes. We comply with ISO 9001 (Quality Management) and ISO 14001 (Environmental Management) certifications.
Validation confirms that your cleanroom meets cleanliness standards and regulatory requirements—critical for maintaining product quality, safety, and compliance.
The cost of a cleanroom depends on several factors such as the required ISO classification, air filtration system, HVAC design, materials used for walls, floors, and ceilings, as well as humidity and temperature controls suited to the Philippine climate. Project size, complexity, and compliance requirements (like cGMP or ISO standards) also play a major role in determining overall investment. For accurate pricing tailored to your needs, it’s best to consult directly with a qualified cleanroom contractor.
- ISO standard: At least every 12 months
- Pharma (FDA/cGMP): May require 6-month certifications
- More frequent checks may be needed after equipment changes, renovations, or contamination events.
Yes. Many warehouses and industrial spaces can be retrofitted into cleanrooms if the structure can support airtight construction, specialized HVAC, and load-bearing requirements.
Is the process of testing and confirming that a cleanroom meets required standards(such as ISO 14644-1 or cGMP) for air cleanliness, airflow, temperature, humidity, and pressure. It ensures the facility is performing correctly and is compliant for safe operations.
Small cleanrooms (50–100 sqm): 3–4 months
Medium (100–500 sqm): 5–7 months
Large (500+ sqm): 8–12 months
These vary depending on complexity, imported equipment, and local permit processing (which can add a few weeks).
Contamination is managed by:
HEPA/ULPA filtration for particle control
Air changes per hour (ACH) based on classification
Pressure cascades to prevent backflow of dirty air
Personnel gowning protocols and material airlocks
The HVAC system is the heartbeat of a cleanroom — it keeps clean air flowing, controls temperature and humidity, and protects against contamination. From a technical view, it regulates air cleanliness, airflow patterns, pressure differentials, and redundancy, ensuring the cleanroom stays compliant with ISO or GMP standards and continues operating even during power or system issues.
