I use a rechargeable dessicant in an waterproof file box.

I do the same... I installed a waterproof storage box above my printer and and route the filament guide tubes into the bottom of the box. Within the box I have a paper lunch bag of drierite dessicant.

I have a humidity meter, and outside of the box it is usually 40-50% inside the box it's about 3%. Once it goes over 10% I recharge the dessicant.
