How long do you have filament sitting “in the open”? I mostly print with a single filament roll at a time, and just leave it on the printer. A 1kg roll lasts me several weeks. For long time storage I keep it in an air tight box with disiccant pouches.

But how long can I let it sit before I should start storing it with disiccant and/or drying the filament before use?

    In a high humidity environment (apparently different from most lemmy users, but like where most people live), PLA starts to visibly degrade in a month on 60% humidity, and much quicker when it’s higher. Not enough to destroy your prints, but enough to harm their finish and possibly a bridge here and there.

    I don’t see any point on storing them better if you are still printing once in a while. But it may be useful to dry them before a more demanding print or every few months.
