How are people keeping their filament dry?

Interestingly, he noticed that his filament was actually drying at room temperature in the box with that thing. Without heat.

Yeah, this is because “that thing” transfers the humidity continuously out of the AMS. But it dries the filament more slowly than a heated filament dryer. To get the moisture out of the filament faster then it is useful to heat up the air. That’s the physics behind both ways.
