If one or more of the HEPA filters are replaced in the ante/buffer area, does the room need to be recertified (non viable particle count)? I would think yes, but I am getting opposition stating that only leak testing and ACPH need to be done. It doesn't make sense to me that you wouldnt do particle counting to certify the room to ensure after HEPA filter replacement, that your room is still meeting that ISO class (7 or 8) that is expected.

Thank you for your expertise on this matter, I greatly appreciate it. I want to make sure we are doing the right thing, and not performing the non-viable particle counting after replacing the HEPA filters did not feel like the right thing to do.
