You need to keep the filament dry. If it’s out of a low-humidity box it will suck up all the water in the air. Have a look at the filament manufacturers' website, and look at their instructions, most recommend drying the filament out in an oven at 65 degrees c for between 2-6 hours. You need to look after your filaments and store them in dry boxes. Humid filament is responsible for a huge percentage of failed prints. I use these for my filaments to keep humidity down, I manage to get 3 normal-size spools in each box, I have 16 of these boxes. they are available in the US as well
