ISO 6 Cleanrooms
An ISO 6 clean room (Class 1000 cleanroom) is a soft- or hard-sided wall manufactured structure that utilizes HEPA filtration systems to maintain air cleanliness levels of a maximum of 1,000 particles (≥0.5 µm) per cubic meter of inside air. Class 1000 cleanroom filtration system must provide filter coverage of 20-30% and – a minimum of 180 air changes per hour. The standard air flow rate for an ISO 6 filtration system is 18-32 CFM per square foot.
Cleanrooms By United produces extremely practical ISO 6 cleanrooms that meet all required specifications and requirements. We provide the layout, square footage, and features that your project specifications require. The custom, flexible, modular construction of our ISO 6 clean rooms makes them easy to expand, reconfigure, or relocate as your cleanroom needs evolve.

ISO 6 Cleanroom Standards
Classification for cleanrooms ranges from ISO 1 to ISO 9, with ISO 9 being the “dirtiest” and ISO 1 being the “cleanest.” These classifications are assigned based on the maximum allowable concentration of particles per cubic foot or meter of air. An ISO class 6 cleanroom was previously defined under US Federal Standard 209E but is now defined under ISO 14644-1, however, both are still regularly used as reference points.
- US Federal Standard 209E: denotes the number of particles (≥0.5 µm or larger) per cubic foot (f³) of air.
- ISO 14644-1: replaced federal standard 209E in 2001 but is still used as a reference. It denotes the number of particles (≥0.1µm to ≥5µm or more) per cubic meter (m³) of air.
ISO 14644-1 Standard for Maximum Number of Particles Permitted/m³ for ISO 6 Cleanrooms
(FED STD 209E Equivalent: Class 1,000)
|≥0.1 µm||≥0.2 µm||≥0.3 µm||≥0.5µm||≥1µm||≥5 µm|
US FED Standard 209E Maximum Number of Particles Permitted/ft³ for Class 1,000 Cleanrooms
(ISO 14644-1 Equivalent ISO 6)
|≥0.1 µm||≥0.2 µm||≥0.3 µm||≥0.5µm||≥5 µm|
What Type of Cleanroom is Right for Your Project?
A typical cleanroom is designed to keep outside contaminants and particles at a minimum based on the ISO clean room standards. Once fully built and operational, an isolated cleanroom is free from outside particles and contamination. However, the two things that can introduce particles and contamination into your cleanroom are people and processes.
Classification for cleanrooms ranges from ISO 1 to ISO 9, with ISO 9 being the “dirtiest” and ISO 1 being the “cleanest.” These classifications are assigned based on the maximum allowable concentration of particles per cubic foot or meter of air. The lower the ISO class the more stringent the requirements for keeping particles and contamination to the acceptable levels of the room class.
As an example, Class 10,000 cleanroom filtration systems must provide filter coverage of 15-25% and – a minimum of 60 air changes per hour. The standard air flow rate for an ISO 7 filtration system is 9-16 CFM per square foot. The chart below provides an explanation of the differences between our clean room classes.
ISO Class 6 Cleanroom Gowning Protection Specifications
Cleanroom requirements vary widely based on industry standards and the type of processes being performed. Always consult with a cleanroom professional for assistance in selecting the design and classification that are best suited for your application. Class 1000 gowning requirements include:
- Hair nets
- Beard covers
- Shoe covers
ISO Class 6 Protective Requirements
To maintain the ISO 6 cleanliness classification, cleanrooms implement gowning protocols to prevent contamination from people and clothing. Required gowning attire for Class 1000 cleanrooms typically includes coveralls, hoods and shoe covers/booties made from non-woven materials. Gloves are also worn to protect sterilized surfaces from contamination.
In addition to gowning requirements, air showers and pass-through chambers are typically incorporated into the design of an ISO 6 cleanroom to prevent contaminants from entering the environment. Specific gowning protocols for Class 1000 cleanrooms can vary based on the industry and application. It is critical that you work with a cleanroom consultant to determine what preventative measures are necessary for your specific application. Common ISO 6 cleanroom contamination protection measures include:
- Product pass thru’s
- HEPA fan filters
- Heat welded vinyl or epoxy floors
- Gowning atrium
- Air locks
- Air conditioners
- Entrance and exit sticky mats
- Sealed lighting
- Bunny suit, booties, and hood requirements
- Stainless steel bench and hands free sink
ISO 6 Cleanroom Applications
