Is a Softwall Cleanroom cleaner than a Hardwall Cleanroom, or vice versa?

Both Hardwall and Softwall Cleanrooms can be designed to be on par in terms of the air change per hour. However, you’ll get a better barrier with Hardwall Cleanrooms. Furthermore, Hardwall Cleanrooms give you more control over humidity and atmospheric temperature. While Softwall Cleanrooms have the advantage of being mobile, they are not as easy to clean and airflow can be more turbulent, since the walls are not fixed. Also, Hardwall Cleanrooms are better at preventing particulate intrusion, as they can hold a significant positive pressure.
