Cleanroom “Grades” and Industry Demands

Cleanrooms are rated by ISO classes (ISO 1–9) or older Federal Standard 209E (Class 1–100,000), which specify the maximum number of particles per cubic meter of a certain size.

• Mushroom production: A functional, “dust‑free” mushroom grow space usually sits closer to an ISO 7–8 environment if designed well (not as rigorous as semiconductors, but way cleaner than a normal room).
• Other industries:
  • Microelectronics / semiconductor: Require ISO 1–5. This is incredibly strict—airlocks, full suits, particle counters. A mushroom grow room would be far too “dirty” by these standards.
  • Pharmaceuticals / biotech labs: Usually ISO 5–7, depending on process. A mushroom cleanroom could sometimes meet the lower‑end (e.g., ISO 7), but you’d likely need more documentation, monitoring, and higher‑end HVAC.
  • Food production: Often doesn’t require ISO‑defined cleanrooms, but benefits from a “controlled environment” like what you’ve built, since dust control and sanitation are paramount. A mushroom cleanroom could double nicely for artisanal food processing (cheese, fermentation, chocolate).
  • Medical device assembly: Typically ISO 7–8, so with a design upgrade, your mushroom room could serve here too.
