I used to dry shrooms in a tote with a bucket of damp rid, it's not exactly the same but they get dry real fast. I suppose it would work for filament, too.

No, it will not. It will help protect it from ambient moisture, but it won't remove moisture already within the filament, since the filament itself acts as a desiccant.
I use a modified food dehydrator. It’s cheaper than a filament dryer and does the same thing. You can often find them used for a good price. From my experience desiccant alone is not enough to dry out a filament.
A decent filament dryer is about $40 - 70. Might be worth the investment if you think you'll run into this issue frequently.
I've successfully dried filament with these Eva Dry packs: https://a.co/d/eBVuUEE
I'm sure a dehydrator would be faster and drier, but I've used these to take a roll from printing poorly to printing acceptably in a few days. Just make sure it's freshly recharged and you put them together in a small airtight container.
Get a food dehydrator. It's about the price of a roll of filament.
I would very much recommend a filament dryer for these purposes.
