I already know the answer to this but just wanted confirmation.
Its been very difficult for our Facilities to adjust the Clean Rooms especially with the hot and humid summer we just had. Their answer was to temporarily use a portable dehumidifier in the room to get the humidity down to 60%. I'm against placing this unit in the Clean Room. Right now, we're at our upper limits of the temperature (68F) and the humidity (60%) but the staff is suffering (with their gown and mask and gloves). It's been tough for them. Am I right to argue against the portable dehumidifier?

A portable unit has standing water is very problematic to have in the buffer room. How do you know that the airflow in the PECs are not disturb by the blowers? I strongly recommend against this solution. They need to introduce the conditioned air in ducts before the HEPA filters.

Humidity below 60 and improving with the end of summer. Currently running mid 40% RH but we were near 55% in late July early August. Made some adjustments watching pressure differentials but a backup plan using a portable dehumidifier was something we talked about.
