I print in my basement and keep a dehumidifier on 35%. Right now it’s down to 20% because winter. I have a dryer and will usually dry out a new roll. But many times I’m lazy and leave them on the spool and they usually print just fine.

    I store all my filament in ziplock bags with some 3a molecular sieve - even after 2 years in 45-65% humidity at 21C room I don’t have to dry PETG.

      I do about the same. Usually I’ll throw the silica packets that come with the roll in my filament dryer and then in the bag.

        Check silica packet effectiveness below 50% humidity… It’s not great. Molecular sieve on the other hand has no problem getting humidity below 5%. I managed to buy a 10kg bucket of 3A sieve for about $120 and it’s going to be enough for many years.
