This is such great input! Thank you everyone.
I was concerned about the cost of running the humidifiers, so it’s really great to hear all of your experiences. I’ll definitely look into the other system you all have used and share this information with my committee.
We went through our CAP this last year, and the conservator did say that this is something that we need to address. My museum gets very dry, and experiences some pretty bad fluctuations. The humidity is one way we’re addressing the environment. You’re right about the air leaks, too. That was another thing that came from our CAP that we’re addressing.
Thank you all again for your help! Please feel free to keep the info coming.
