The main problem, I believe is that there is a lack of good sealing on the lid for this particular humi. But it's not just this one, I'm really curious about things to try with any of them in general. For instance, what about expanding insulation around the base, to fill in any gaps (remove the felt bottom and fill any dead space there)? I worry, though, about the use of any chemicals...
Yeah, I would avoid that if you can. Is there a good sized gap from the lid to the bottom? You might be able to use some very thin closed cell weatherstripping to help there. Only if there is a decent sized gap, otherwise the lid might not shut all the way.
