ISO Cleanroom 7 vs. 8: What’s the Difference?

The future of website creation is here.

However, while many people know that our iso class 7 cleanroom is great for medical manufacturing, the difference in ISO classes can occasionally be confusing. That’s why we’re breaking down the differences between iso class 7 and ISO class 8.

So why did we choose to build an ISO class 7 cleanroom? Keep reading.

BASIC ISO DISTINCTIONS

Cleanrooms are spaces that are kept particularly sterile or free of particles in order to provide a safe environment for anything that needs to be clean. These are measured from ISO Class 1 to 9, with 1 being the cleanest.

Each different class is measured by multiple factors, and a room must meet all of them to qualify for the classification.

KEEPING IT CLEAN

One of the key distinctions between cleanroom classes is the amount of air changes per hour. This is the amount of times that air is filtered through HEPA filters. The more times it’s filtered, the less particles there are in the air.

A typical room has between 2-4 changes every hour. iso class 8 cleanrooms typically have between 10-25 air changes every hour, while ISO Class 7 have between 30-60. That means that in our ISO Class 7 cleanroom, the air is filtered at least thirty times every hour. Particles are consistently filtered out to provide clean air for medical device production.
