Building a cleanroom is a fundamental investment for industries that demand the highest levels of precision and control over their environment. These controlled spaces are crucial for ensuring product integrity and reliability. Understanding the various cost factors can help in accurately budgeting for the construction of cleanrooms across different iso classifications.

Factors Influencing Costs


  • Area: Larger spaces require more materials and labor, directly impacting total costs.

  • ISO Classification: Higher classifications demand advanced filtration and control measures, increasing costs.

  • HVAC System: Critical for air quality control, advanced setups are a major expense.

  • Construction Materials: High-quality, easy-to-clean materials are essential for compliance.

  • Geographic Location: Varies by labor rates and local regulatory requirements.

Area Area

The size of the cleanroom is directly proportional to the cost. Larger facilities require more resources in construction materials, energy, and maintenance. Strategic space planning optimizes efficiency without unnecessary expenditures.

ISO Classification ISO Classification

Determines the level of cleanliness and technological sophistication. Higher classifications (e.g., ISO 5) require advanced filtration systems, leading to higher costs.

HVAC System HVAC System

A cornerstone of cleanroom functionality, controlling temperature, humidity, and particle filtration. Advanced systems are critical for compliance and product safety.

Cleanroom Construction Costs by ISO Classification

ISO ClassificationCost RangeKey FeaturesApplications

ISO 5

$1,000 - $2,000 /m²HEPA/ULPA filters, advanced airflow designPharmaceuticals, microElectronics

ISO 6

$600 - $800 /m²Sophisticated filtration, modular systemsMedical devices, precision optics

ISO 7

$500 - $600 /m²

Reduced particle control, efficient HVAC

Biotech, medical devices, electronics

ISO 8

$300 - $500 /m²Basic particle control, cost-effective designFood processing, assembly areas

ISO 5 ISO 5 Cleanroom

Require extremely rigorous standards for particle contamination. Advanced Air Filtering systems (HEPA/ULPA) are essential, with construction costs ranging from $1,000 - $2,000 /m² per square meter.

ISO 6 ISO 6 Cleanroom

Slightly more relaxed standards than ISO 5, with costs between $600 - $800 /m² per square meter. Ideal for industries requiring moderate particulate control.

ISO 7 ISO 7 Cleanroom

Widely used across industries, with costs from $500 - $600 /m² per square meter. Reduced particle count requirements make them versatile for many applications.

ISO 8 ISO 8 Cleanroom

The most lenient classification, with costs ranging from $300 - $500 /m² per square meter. Suitable where minor particle contamination doesn’t affect product quality.
