The relationship between the price of modular cleanrooms and their area is significant, as larger cleanroom spaces generally incur higher costs. Pricing is often based on a cost-per-square-foot or square-meter basis, meaning that as the size increases, the total expenses rise accordingly. This increase in cost reflects not only the additional materials required but also the need for more complex systems, such as heating, ventilation, and air conditioning (HVAC) and advanced filtration systems, to maintain stringent cleanliness standards.
Moreover, customization plays a crucial role in determining the final price. Larger modular cleanrooms may require tailored designs and configurations to meet specific operational needs, which can further drive up costs. Therefore, when planning a cleanroom project, it's vital to consider both the area and the desired functionalities to ensure that the investment aligns with industry requirements and budget constraints.

Composition of the cost of building a clean room
The construction of a clean room includes not only construction costs, but also equipment procurement, air purification systems, environmental monitoring equipment, etc. The construction cost varies greatly depending on the specifications, grades and scale of the clean room.
1.1 Architectural design and room structure
The architectural design and structure of a clean room determine its overall quality and long-term use effect. The complexity of the design directly affects the construction cost.
Wall and floor design
To ensure smooth air flow, clean rooms often use special materials such as dust-proof coatings and wear-resistant floors. Design requirements make these materials costly, about $100 to $200 per square meter.
Airflow management
Clean rooms require specially designed airflow paths to avoid dust accumulation in dead corners. To ensure cleanliness, airflow design will add about 15%-20% additional costs.
Architectural structure and design usually account for 30%-40% of the total budget.
1.2 Air purification system and equipment procurement
The core equipment of a clean room is the air purification system. Depending on the cleanliness standards, the specifications and prices of the equipment vary greatly.
High-efficiency air filtration system
HEPA filters or ULPA filters are common choices. The cost of a single HEPA filter ranges from about $100 to $500, depending on the filter efficiency and size.
Ventilation system
According to ISO 14644-1, ISO5 clean rooms require at least 60 air changes per hour. The construction cost of an air exchange system is about $30,000 to $100,000.
The purchase and installation of air purification systems and equipment usually accounts for 30%-50% of the total budget.
1.3 Environmental monitoring and management system
The environmental monitoring equipment of the clean room helps monitor the air quality in real time to ensure compliance with international standards. The monitoring system involves particle counters, temperature and humidity control, and pressure difference detection equipment.
Particle counter
Each particle counter costs about $5000 to $20,000, depending on its detection capabilities and accuracy.
Pressure difference monitoring
In order to ensure the correct air flow, pressure difference monitoring equipment is also essential, costing about $2,000 to $10,000.
The environmental monitoring system usually accounts for 10%-15% of the total budget.
Factors affecting the cost of clean room construction
The construction cost of a clean room is affected by many factors, and understanding these factors can help to more accurately budget the construction costs.
2.1 Clean room grade and standard
The grade of the clean room is a key factor affecting the cost. According to the international standard iso 14644-1, the higher the level of the cleanroom, the stricter the requirements for design, equipment and materials, and the higher the cost.
The particle concentration is required to be less than 3,520 0.5 micron particles per cubic meter, and the construction cost is relatively high. The construction cost per square meter may reach more than $1,000.
The particle concentration can be as high as 352,000 0.5 micron particles per cubic meter, and the construction cost is relatively low. The cost per square meter is about $500 to $700.
High-level cleanrooms require more air exchange equipment and filtration systems, and the cost is usually twice or more than that of low-level cleanrooms.
2.2 Project scale and building location
The scale of the cleanroom is closely related to factors such as construction costs and labor costs at the project location, which will affect the final budget.
Project scale
Large-scale cleanrooms require more equipment and materials, so the construction cost is significantly increased. For example, the construction cost of a 1,000 square meter ISO5 cleanroom is approximately $500,000 to $1,500,000.
Geographic location
The construction market, labor costs, and transportation costs of the project location will affect the budget. In first-tier cities in the United States (such as New York or San Francisco), labor and construction costs are higher, which may make the construction cost of a cleanroom of the same specifications 20%-30% higher.
Differences in project size and location will lead to cost differences, which can be further evaluated based on specific projects.
2.3 Equipment Brand and Quality
The brand of equipment and materials selected also directly affects the construction cost. High-end brands generally provide higher quality and longer service life, but cost more.
Filter equipment brand
For example, using filter equipment from well-known brands such as 3M and Honeywell, the price of a single HEPA filter may exceed $1500, while the price of filters from more common brands is approximately between $500 and $1000.
Air conditioning and air exchange system
Efficient air conditioning systems and exchange equipment not only improve energy efficiency and reduce later operating costs, but the initial purchase cost is usually high.
Although the initial investment of high-end brand equipment is large, it can effectively improve cleanliness and reduce long-term maintenance costs.
Later maintenance costs
The later maintenance costs of clean rooms include not only equipment maintenance, but also energy consumption, personnel management and facility inspections.
3.1 Equipment maintenance and replacement
The equipment in the modular clean room (such as HEPA filters, air conditioning systems) needs to be maintained and replaced regularly. The filter system needs to be replaced, and the air conditioning system also needs to be inspected and cleaned regularly.
HEPA filter replacement
The replacement cost of each HEPA filter is US$300 to US$1000, and it is usually replaced every 6 to 12 months.
Air conditioning system inspection and maintenance
The maintenance cost of the air conditioning system is approximately US$10,000 to US$50,000 per year, depending on the size and frequency of use of the clean room.
Regular maintenance and replacement of equipment ensures long-term stable operation of the cleanroom, but it will generate continuous operating costs.
3.2 Energy consumption and operating costs
The cleanroom needs to operate continuously for 24 hours, consuming a lot of electricity, especially in large and high-grade cleanrooms. Energy costs are one of the main parts of operating expenses.
Air conditioning and ventilation system
The air conditioning and air exchange systems of large cleanrooms consume a lot of energy, and the annual electricity bill may be as high as US$50,000 to US$200,000, especially in tropical or high-temperature areas.
Lighting system
Modern cleanrooms use LED lighting, which is energy-saving, but the electricity bill for lighting throughout the year can also reach US$10,000 to US$50,000.
Through intelligent energy management systems, enterprises can optimize energy use, reduce energy consumption and operating costs.
3.3 Personnel management and operation
The daily management of the cleanroom requires professional personnel to operate and maintain. Personnel training, wages and equipment usage costs are costs that cannot be ignored.
Operator training
Annual training costs are approximately $10,000 to $30,000 to enhance operators' expertise in cleanroom operations.
Environmental monitoring personnel
Cleanrooms require dedicated monitoring personnel for real-time monitoring, and their annual salary is generally between $30,000 and $70,000.
Personnel management is the key to ensuring that cleanrooms meet international standards and operate normally.
Cleanroom construction cost reference case
Based on actual conditions, the following is a budget estimate for the construction of cleanrooms of different specifications.
Small ISO7 cleanroom
The construction cost is approximately $300,000 to $600,000, and the annual operating cost (including maintenance and energy consumption) is approximately $50,000 to $100,000.
Medium-sized ISO5 cleanroom
Construction costs are $600,000 to $1,200,000, and annual operating costs are approximately $100,000 to $200,000.
Large-sized ISO5 cleanroom
Construction costs may exceed $2,000,000, and annual operating and maintenance costs may reach more than $500,000.
The above budget is only a rough estimate, and the specific cost needs to be further calculated based on the project scale, equipment configuration and regional differences.
The construction cost of a cleanroom is affected by many factors, including cleanliness level, architectural design, equipment selection, project scale, etc. Overall, the cost of cleanroom construction is usually between hundreds of thousands of dollars and millions of dollars. In addition to the initial construction investment, the later maintenance and energy consumption of the cleanroom will also have an important impact on the operating cost. Therefore, when constructing a cleanroom, reasonable budget planning and long-term cost control are essential.
