Softwall Cleanrooms
Softwall cleanrooms offer businesses a working solution to keeping clean, controlled environments without the cost or downtime of permanent construction. Designed for flexibility and pace, they are simple to install, reconfigure as business dictates, and reuse across industries from pharma to electronics. For temporary production, seasonal cycles, or on-the-move testing, softwall cleanrooms give businesses the flexibility to stay compliant and affordable without long-term infrastructure investment.
Softwall cleanrooms are a flexible alternative to permanent hardwall designs. They are commonly used when projects require moderate cleanliness (ISO 7–8), quick deployment, or cost-sensitive solutions.
When Softwall Cleanrooms Are Used
- Temporary or Short-Term Needs: Softwall cleanrooms are useful for projects that only need a cleanroom for a limited duration, such as specific production runs, equipment testing, or temporary setups like R&D labs testing prototypes, seasonal production surges in pharmaceuticals or food packaging, trade shows, or on-site demos.
- Rapid Deployment: When a cleanroom must be up and running quickly (sometimes in hours or days), softwalls can meet urgent operational needs. Some examples are emergency medical supply packaging during pandemics, quality control during manufacturing expansions, mobile testing for aerospace or automotive.
- Cost-Sensitive Projects: Softwall cleanrooms are often chosen when budgets are tight, since they are far less expensive than permanent hardwall cleanrooms. They’re frequently used by startups in biotech or electronics, or facilities retrofitting existing space without structural changes.
- Flexible or Reconfigurable Workspaces: Softwall cleanrooms can be moved, resized, or reconfigured to fit changing workflows like in modular production lines, labs with varying experimental setups, leased facilities where permanent fixtures are not practical.
- Containment Needs: Softwall cleanrooms can be designed with negative or positive pressure to either contain contaminants or prevent intrusion. Some examples: Handling biohazards in labs, containing powders or aerosols in chemical processing.
- Specific Industry Applications: Softwall cleanrooms are used in many industries. In pharmaceuticals for compounding, packaging, or sterile processing in ISO 7–8. In electronics for circuit board or semiconductor assembly. In medical devices for packaging or assembly with low particle counts. In aerospace for assembly of precision components. And in food & beverage for packaging or hygienic processing.
Conditions for Using Softwall Cleanrooms
- Cleanliness Requirements: Usually used for ISO 7 (Class 10,000) or ISO 8 (Class 100,000) where moderate particle control is sufficient.
- Environmental Flexibility: Best for spaces where permanent construction is not possible (leased buildings, existing rooms, or layouts that change often).
- Temperature and Humidity Control: They operate well in standard indoor ranges (20–25°C, 30–60% RH). For example, electronics labs maintaining moderate humidity to prevent static. More advanced setups can tie into HVAC for tighter control.
- Portability and Mobility: They are often mounted on casters or designed as lightweight “cleantents”.
- Budget Constraints: Softwall cleanrooms are usually 30–50% cheaper than hardwall ones, especially for materials and installation. A small biotech firm setting up a pilot production line can benefit from this type of cleanroom.
- Regulatory Compliance: Softwall spaces can meet USP 797, GMP, and ISO 14644-1 for ISO 7–8 environments.
- Containment Environments: They can include negative pressure to contain hazards or positive pressure to keep particles out.
- Space and Accessibility: They can fit in small areas, and clear vinyl walls provide visibility into operations.
Limitations of Softwall Cleanrooms
- Not suitable for ultra-clean environments (ISO 5 and stricter).
- Less effective in extreme environments (very high humidity or temperature).
- Less durable in high-traffic settings compared to hard walls.
- Not ideal for high-risk hazardous materials unless specially designed.
Practical Examples
- Pharmaceutical Compounding: A pharmacy may install an ISO 7 softwall cleanroom for sterile meds to be compliant with USP 797.
- Electronics Assembly: A startup may use a portable ISO 8 softwall cleanroom for circuit boards at low cost.
- Temporary Testing: An aerospace firm may set up a mobile softwall cleanroom on wheels to test components on-site.
Softwall cleanrooms are best when flexibility, speed, and affordability are top priorities. They work well for ISO 7–8 environments, can be deployed quickly, and reconfigured as needed, though they are not suitable for ultra-strict or permanent applications.
Fast Deployment
Softwall cleanrooms can be installed within hours or days. As a result, they’re great for urgent needs like temporary R&D or quick quality-control setups.
Affordable Compliance
Costs are significantly lower than hardwall cleanrooms, and they can make ISO 7–8 compliance possible without too much investment.
Flexible & Mobile
They can be expanded easily, or even placed on wheels, which makes them an excellent choice for seasonal production or labs that need adaptable layouts.

FAQs About Softwall Cleanrooms
What are the key differences between softwall and hardwall cleanrooms?
Softwall cleanrooms use lightweight vinyl curtains or panels, making them faster and more affordable to install, reconfigure, or relocate. They are ideal for temporary or cost-sensitive projects and usually meet ISO 7–8 standards.
Hardwall cleanrooms, on the other hand, are built with rigid wall panels for greater durability, tighter environmental control, and support for stricter classifications (ISO 5–6). They are better suited for long-term, permanent facilities requiring ultra-clean or highly regulated environments.
When should I choose a softwall cleanroom for my pharmaceutical facility?
Softwall cleanrooms are ideal when you need a fast, flexible, and cost-effective solution. They are perfect for temporary or short-term projects, seasonal pharmaceutical production, R&D labs, or mobile setups that must be deployed quickly. Their ability to be reconfigured, expanded, or relocated makes them a smart choice when workflows or facilities change frequently.
What ISO classifications do softwall cleanrooms typically meet?
Softwall cleanrooms are most commonly used for ISO 7 (Class 10,000) and ISO 8 (Class 100,000) environments. This level of particle control is sufficient for many pharmaceutical compounding, packaging, and sterile processing applications. For ultra-clean requirements (ISO 5 or stricter), a hardwall or hybrid cleanroom design is more appropriate.
Are softwall cleanrooms compliant with pharmaceutical regulations?
Yes. Properly designed softwall cleanrooms can meet USP 797, GMP, and ISO 14644-1 standards for ISO 7–8 environments. They can also incorporate positive or negative pressure systems depending on whether you need to prevent contamination from entering or contain hazardous substances inside.
What are the limitations of softwall cleanrooms compared to hardwall systems?
Despite their affordability and speed, softwall cleanrooms have some limitations. They are not suitable for ultra-strict ISO 5 environments, are less durable for high-traffic or long-term use, and perform less effectively in extreme humidity or temperature conditions. Additionally, they may not be the best option for handling high-risk hazardous materials unless specifically engineered for containment.
