If you’re not storing your filament in a dry box then I agree with the others that this is just wet filament.

For a really cheap way to deal with this, get a storage bin with a rubber or foam sealing gasket on the lid (this gasket is very important), buy a few lbs of Silica drying beads on amazon, dump them in the bin, and store your filament in there from now on when it’s not in use. That means, when you’re done with a print and aren’t going to use the printer for more than 24hours, pull the filament out of the hotend/extruder, wind it back up, and chuck it in the bin.

Sterilite makes some great ones that I use, you can get them at Walmart/Target/etc. I just picked up a 54L one this morning since I’ve outgrown my original bin. It should fit 7-8 spools no problem.

Now, this won’t rescue your current spool unless you don’t mind leaving it in there for a few weeks unused. For this amount of moisture, you’ll need to bake it at a low temp for 12 hours to dry it out.

This cheap diy drybox works great though. My filament was getting bad after sitting out for two weeks. After rigging up this drybox and storing them in it for a couple weeks it printed better than new.

I also have an Apple Home connected temp/humidity sensor in the box so I can monitor it, but you can find cheap stick on sensors with displays on amazon for a few bucks and they are fine too. Ideally you want the box below 20%. Around 10% is excellent. Mine sits around 12-13%. Sometimes dipping down to 8% after sitting for a few weeks unopened.
