Hi all,

I’m doing an experiment with a cabinet for filament with a small dehumidifier in it. I can get it to sit at 35%, but not much lower. I’ve sealed the cabinet with foam tape, and dried most of the filament first.

Are there any tricks to help improve performance of the mini dehumidifier? Maybe adding more heat to the cabinet?

The goal would be to use Home Assistant and the humidity sensor to turn things on and off as needed.

Thanks!

    Wood breathes. You will need something watertight lining the inside. Paint is not enough. 8mm plastic is my first thought - but many plastics also allow moisture through and I’m not sure what is safe. An epoxy finish on the inside might work. But getting a continious layer could be a pain.

      That is hardly wood. And the coating itself is airtight by itself. Focus on the cracks at the back wall and it shouldn’t be an issue anymore.

      Hmm had not considered this, but I doubt that’s having an impact on minimum humidity (currently), as that feels like it would impact when the system isn’t running?
