Which of the following describes the types of cleanrooms?

The correct response identifies that cleanrooms can be categorized into two primary types based on airflow: non-unidirectional (conventional) and unidirectional (laminar flow).

Non-unidirectional cleanrooms, also known as conventional cleanrooms, utilize turbulent airflow patterns, where air mixes and circulates in various directions throughout the room. This type of cleanroom is effective for many applications but may not be suitable for processes requiring the highest levels of cleanliness.

In contrast, unidirectional cleanrooms, commonly referred to as laminar flow cleanrooms, maintain a consistent air flow in a single direction, creating a cleaner environment by minimizing particles and contamination. This airflow method allows for a higher degree of cleanliness, making it ideal for sensitive processes such as semiconductor manufacturing or pharmaceutical production.

Understanding these classifications is crucial for determining the appropriate cleanroom design based on the specific needs for contamination control in various industries.
