How low should storage humidity be?

Filament

I have set up a container with desiccant. I also have a humidity monitor. So the question is how low should the humidity be?

Thanks!

Your storage humidity should be below 20 percent. 15 percent should work pretty well for you. Also remember that certain filaments such as PVA are basically Elmer’s glue on a reel, so you’ll want to store that type of filament when not in use.
