I print headjoints for my Breath Flute project in different colors and materials (PLA vs TPC/Copolyester), so I need to store them for a long time.
I keep each roll of filament in a separate, re-sealable (Zip-lock) poly bag with it's own renewable dehumidifier and a small individual hygrometer. These bagged filament rolls are grouped into clear 44-quart storage boxes.
More info on the individual components:
-
Poly Bags: I generally use 4 mil "poly" bags from Plymor or Uline. They are made of LPDE and Polyethylene, respectively. The 4 mil thickness feel reassuringly solid. The Plymor bags are on their store on Amazon: https://www.amazon.com/stores/page/12B315CE-97CA-472B-9026-DB8732D7F438 . Uline bags can be found at: https://www.uline.com/BL_211/Uline-4-Mil-Reclosable-Bags
-
Dehumidifier: I use Eva-Dry E-333 dehumidifiers. They convenient, have an indicator as to remaining capacity, and can be renewed by plugging them in for 18 hours (no more than that!). They bring the relative humidity down to 10-15%. The manufacturer's page is at https://www.eva-dry.com/product/e-333-renewable-dehumidifier/. They are available on Amazon at a discount.
-
Hygrometer: I use inexpensive EEEKit 56 mini hygrometers. They are no longer available, but an Amazon search for "EEEKit 56" produces lots of similar units.

Storage box: IRIS USA WSB-SD Ziploc WeatherShield 44 Quart Storage Box, Clear. https://www.amazon.com/gp/product/B07C882DVV/
So, possibly a similar setup using poly bags, or maybe a clear Lexan box of some sort ...
I do use a dedicated filament storage box / dispenser for filament that is being fed live into the printer. That specific box is by Polymaker and is here: https://www.amazon.com/Polymaker-PolyBox-Filament-Filaments-Printing/dp/B075DBPY6F. However, for other ideas, search on Amazon for "3D Printer Filament Storage Box".
