  1. The filament is a little bit porous, and many filaments containt organic materials, such as the wood filament. It will absorb some moisture, like a grain of rice.

    The filament can change a little in size, or stick to itself if it absorbs enough humidity, affecting how well the filament will feed.

    Also, if you take filiament that is humid, and run it through a hot extruder, the moisture will turn into steam, and cause your filament to puff up like a cheese puff. (A bit of exageration here, but you get the idea.)

    The silica will change color to pink from white, after it absorbs moisture. The good thing though is that the silica can be refreshed in an oven or microwave.

    Lots of instructions on how to do this online.
