My office is in the basement so it gets pretty humid (it's half below ground). It's reading 57% humidity right now, but I've seen it as high as 65%. I think you want to store it ideally under 40%.
I recently had a few wet spools because they were very brittle and when printing would come out with poor quality. After that, I invested in better storage containers (that are airtight), desiccant, and hygrometers to check on the humidity within the containers.
I previously just threw some dessicant packs in Ikea Samla containers (that are not airtight). My friend said he has never had issues with wet filament doing that so I just did what he did, but I think my basement might just be more humid than his (my house is from the 1950s, his is recently built).
As long as your filament storage bags are airtight, that should be fine. I use these desiccant beads because they turn dark green/blue when they need to be dehydrated.
