Cleanroom Garments
Gowning Apparel for ISO-Class, Aseptic & Controlled Environments
Personnel Contamination Control ISO & Annex 1 Alignment Sterile Options
Cleanroom garments are a primary barrier between personnel and the controlled environment. Human operators are the largest source of contamination in cleanrooms, and garment systems are designed to contain particles, fibers, and microbes generated by movement and activity. Proper garment selection depends on ISO class, process risk, sterility requirements, and gowning protocol.
Best suited for: pharmaceutical and biotech manufacturing, sterile compounding, medical device cleanrooms, microelectronics and semiconductor operations, aerospace, optics, and controlled laboratories where personnel control is critical to yield and compliance.
ISO Class 7–8 environments
→ Non-sterile cleanroom garments
ISO Class 5–6 / aseptic zones
→ Sterile gowning systems
Reusable vs. disposable programs
→ Fabric systems or single-use apparel
Selection Guide
How to choose the right cleanroom garment
Garment selection should begin with the cleanroom classification and gowning SOP. Coverage, material, sterility, and closure design must work together to minimize contamination during donning, wear, and doffing.
Why garment systems are critical to contamination control
People continuously shed particles and microorganisms. Cleanroom garments are engineered to contain this contamination while allowing safe, ergonomic movement. Fabric structure, seam construction, and garment design directly affect performance and comfort.
- Particle containment: fabric and seam design limit particle escape
- Coverage: hoods, coveralls, boots, and cuffs work as a system
- Sterility assurance: sterile packaging supports aseptic workflows
- Operator compliance: comfort and fit influence correct use
Common mistakes to avoid
- Mixing garment systems across ISO classes without validation
- Improper donning sequence that contaminates garment surfaces
- Reusing disposable garments beyond intended use
- Ignoring compatibility with gloves, masks, and footwear
Quick match: garment type by application
| Your environment | Typical garment direction | Why it fits |
|---|---|---|
| ISO Class 7–8 cleanrooms | Non-sterile coveralls, lab coats, smocks | Controls particles while supporting mobility. |
| ISO Class 5–6 / aseptic areas | Sterile gowns, coveralls, hoods | Supports sterility assurance and transfer protocols. |
| Reusable garment programs | Durable fabric systems | Designed for repeated laundering and testing. |
| Disposable programs | Single-use garments | Simplifies change-out and reduces cross-contamination risk. |
Best-practice gowning fundamentals
- Follow the defined donning order: prevents contamination of clean surfaces.
- Ensure proper fit: oversized or tight garments reduce effectiveness.
- Replace when compromised: tears or contamination reduce protection.
- Coordinate accessories: gloves, masks, hoods, and boots must work together.
- Train and audit: consistent gowning practices improve compliance.
For the fastest recommendation, be ready to share: ISO class, sterile requirement, reusable vs. disposable preference, and your gowning SOP.
