YOOPAI Filament Storage Bags 20 Extra Large 14.9x13 inch with Auto Pump

Filament storage kit with auto pump

The YOOPAI kit supplies 20 extra-large vacuum bags measuring 14.9 by 13 inches, an automatic pump, 20 desiccant packs and five sealing clips. It is built for makers who need to keep 1.75 mm filament dry and dust-free after drying. The bags fit Bambu Lab reusable spools and more than 99% of standard 1 kg rolls.

Who benefits and who should look elsewhere

Hobbyists and small-print farms that store up to 20 spools at once will find the kit convenient and reusable. Users with larger inventories, non-standard spool diameters, or a preference for rigid dry boxes will not be served by this flexible-bag system.

Capacity, headroom and limits

Each bag holds one 1 kg roll with ample clearance, so the set handles 20 spools simultaneously. The pump evacuates air quickly, but vacuum level can drop after extensive reuse; periodic re-vacuuming is required for long-term storage. Desiccants provide additional moisture buffering inside each sealed bag.
