EDIT: The video states that PLA and PETG have such negligible water absorption properties that you can basically ignore it. Excessive nozzle temperature causing stringing is the main culprit that people attribute to water absorption.
Check it out. I thought it was super insightful. https://youtu.be/A3H1oFVpUMk

I think it depends on how humid your environment is, but I dry 1 or 2 rolls at a time, and vacuum seal them for long term (>6 months) storage, or if I plan on using it within a few months I just store them in a gallon ziplock back and they're fine. I live in SoCal which is fairly dry, but my experience is unless your printing nylon or other filaments that love absorbing moisture, people oversell the need for constantly drying your filament. IMO, dry it once, and store it well. I use a food dehydrator… I found one on marketplace that I modified to hold 2 rolls of filament. I got it for like $5 and the PO used it for making beef jerky.

So are you saying to never let humidity hit your filiment in the first place because once that happens it will have broken molecular bonds?
I rarely dry more than one or maybe two rolls at a time and it's just easier to use my Polydryer (dries one spool) most of the time for me. If you do pick up a dryer and ever plan on printing some specialty filaments like Nylon, make sure to get one that will hit the temps you need. I think most go to 70 degrees and while you could dry nylon at that temp, it will take a long time.
Some people use a four spool dryer to keep the filament in there and print directly from the dryer, if the filament + environment requires it. Some filaments pick up moisture pretty quickly.

Got it. So experiment with the nozzle temperature with this brand petg in order to get good print.
