Re: Do you monitor both 0.5 and 5 micron in ISO Class 8 cleanrooms?

Each particle size is "this size or larger"...so in effect each of the particle size measurements in themselves is cumulative.

The 0.5um particle size count will always be larger than the 1um particle count since all of the 1um particles are included in the 0.5um particle count.
Thanks to Ninja for your informative Post and/or Attachment!
