eSUN eVacuum Kit Pro 3 Filament Vacuum Storage Bags

Opened filament pulls moisture out of the air, and wet filament means popping, stringing and weak prints. The eSUN eVacuum Kit Pro 3 seals each spool in its own vacuum bag with a desiccant pack, so the filament you open today prints the same way next month. A small USB pump pulls the air out in seconds - no more guessing which spool is still dry.

Key Features

• Electric USB Pump - Compact 75 g pump pulls 4 L/min or more. Press it on the valve, wait a few seconds, done.
• Double-Zipper Seal - Two zip tracks plus a sealing clip keep the vacuum for weeks, and the bags reseal for reuse.
• Fits Almost Every Spool - Sized for 0.5 kg, 0.75 kg and 1 kg spools in 1.75 mm or 2.85 mm. Bambu Lab, eSUN, Elegoo, Creality and Sunlu spools all fit.
• Desiccant Included - 15 desiccant packs, one per bag with spares, so every sealed spool keeps drying inside the bag.
• Food-Grade, BPA-Free Bags - Thick 0.085 mm PA+PE composite, durable, recyclable and safe to reuse.
• Ideal for Hygroscopic Filaments - PA, PA-CF, PVA, TPU, PETG and ABS lose print quality fastest when damp; these are the spools to bag first.
