Keep your 3D printing filament perfectly dry and ready to print with this complete vacuum storage kit. Moisture is the number one enemy of PLA, ABS and PETG filament — it causes stringing, weak layer adhesion and brittle prints. This kit seals each spool in an airtight vacuum bag so your material stays fresh between projects.

The set combines thick food-grade PA+PE composite bags with a high-powered USB rechargeable electric pump that pulls a full vacuum in about 30 seconds. A manual pump is also included for backup use anywhere, and the patented blue indicator window lets you check humidity at a glance without opening the bag.

• Bag Material : Food-grade PA + PE composite film, 0.09 mm thick, reusable and eco-friendly
• Bag Size : 30 cm x 34 cm (11.8 x 13.4 in) — fits a single 1 kg filament spool
• Electric Pump : ABS + PC body, 5.3 x 11 cm, 5V / 3W, 50-60 KPa, full vacuum in 30 seconds
• Manual Pump : PP + ABS body, 4 x 14 cm, vacuum time around 60 seconds
• Temperature Resistance : -20°C to 100°C
• Sealing System : Double-seal zipper plus embossed texture and micro-porous air drainage
• Humidity Window : Patented blue indicator window for real-time moisture monitoring

• ✓ Protects filament from moisture, dust and oxidation so every print comes out clean and strong
• ✓ USB rechargeable electric pump delivers a tight vacuum seal in only 30 seconds
• ✓ Reusable bags and clips cut long-term storage costs compared with one-time desiccant solutions
• ✓ Works with virtually all mainstream 3D printers and standard spool sizes
• ✓ Compact pumps store easily in a drawer or tool box between uses

Place the filament spool flat inside the bag, close the zipper to the second notch, insert the blue vent hole and run the electric pump for about 30 seconds. The manual pump works the same way when no power source is nearby.

Ideal for hobbyists, print farms and workshops that switch between materials often and want to keep every spool in like-new condition.
