Three common misconceptions about modular cleanrooms, which 90% of customers fall into.

Modular cleanrooms, with their advantages of high efficiency, flexibility, and low cost, have become the preferred cleanroom solution for industries such as electronics, pharmaceuticals, and food. However, many customers easily fall into misconceptions during the selection, construction, and operation and maintenance processes, which not only increases costs but may also lead to cleanrooms failing to meet standards, production compliance requirements, and even product quality. This article, based on the ISO 14644-1 standard and years of industry practice, deconstructs three common misconceptions to help companies avoid pitfalls and implement solutions efficiently.

Misconception 1: The higher the cleanliness level, the better; blindly pursuing high levels

This is the most common misconception. Many customers believe that "the higher the cleanliness level, the more guaranteed the production," blindly demanding Class 100 or Class 1000 cleanrooms, ignoring their actual production needs. From a professional perspective, the core of choosing a cleanliness level is matching process requirements, not simply choosing the highest possible level—different industries and different processes have vastly different cleanliness requirements. For example, food filling requires a Class 100,000 cleanroom, chip packaging requires a Class 1,000 cleanroom, while ordinary laboratories only need a Class 10,000 cleanroom.

Blindly pursuing higher cleanroom standards leads to two major problems: First, a significant increase in initial investment. Higher-level cleanrooms require denser FFU (Fan Filter Unit) systems and more sophisticated control systems, increasing costs by 40%-60% compared to suitable standards. Second, soaring maintenance costs. High-level cleanrooms require filter replacements 2-3 times more frequently and consume 2-3 times more energy than standard cleanrooms, making long-term maintenance unprofitable. The correct approach is to have professionals calculate the required cleanroom level based on your own processes and the ISO 14644-1 standard, achieving "precise matching and maximizing cost-effectiveness."

Misconception Two: Focusing Only on Initial Costs, Ignoring Lifecycle Cost Control

Many clients only compare initial construction costs, prioritizing the lowest-priced option, while neglecting the lifecycle costs of modular cleanrooms (initial investment + maintenance costs + renovation costs), ultimately falling into the trap of "saving money upfront but losing money later." Some low-priced solutions, in order to cut costs, use inferior materials, inefficient filters, and simplistic control systems, seemingly reducing initial investment but actually hiding significant risks.

From a professional perspective, inferior board materials have poor sealing performance and are prone to deformation, leading to substandard cleanliness and frequent maintenance. Low-efficiency filters have insufficient filtration effect, easily breeding microorganisms and accumulating dust, affecting product quality and requiring more frequent replacements. Simple control systems cannot accurately regulate temperature, humidity, and pressure differentials, making it difficult to meet GMP and other compliance requirements. The correct approach is to focus on the quality of module materials, filtration systems, and control systems during selection, combined with a comprehensive calculation of later operation and maintenance costs and reuse value, avoiding the pitfall of "repeated repairs and secondary modifications" due to low prices.

Misconception 3: Modular cleanrooms require no maintenance and are worry-free after construction.

Many customers believe that modular cleanrooms, "prefabricated in the factory and assembled on-site," have a simple structure and require no maintenance after construction. This perception directly shortens the lifespan of the cleanroom and affects its cleanliness. In fact, maintaining the cleanliness of a modular cleanroom relies on routine maintenance. Its core components (FFU fans, HEPA filters, and seals) all have a lifespan and require regular inspection, replacement, and calibration.

Key points for professional operation and maintenance: HEPA filters need to be inspected every 6-12 months and replaced promptly based on pressure differential changes; FFU fans require regular cleaning and maintenance to prevent insufficient airflow from affecting airflow organization; seals need to be checked regularly to prevent dust leakage; at the same time, personnel access procedures must be standardized to prevent the introduction of external dust. Long-term neglect of maintenance will lead to decreased cleanliness, increased energy consumption, and even equipment failure, ultimately affecting production compliance and increasing maintenance costs.

Summary: The core of selecting, constructing, and operating modular cleanrooms is "adapting to needs, focusing on quality, and routine management." Avoiding the above three common pitfalls can reduce total lifecycle costs and ensure long-term cleanroom compliance, adapting to the company's production and development needs. It is recommended that companies prioritize service providers with professional design, standardized production, and comprehensive operation and maintenance services when selecting modular cleanrooms to mitigate risks from the source and allow them to truly realize the core values ​​of "efficiency, flexibility, and economy."
