# How should I store filament?

These ranked rows list 190–260 °C (374–500 °F).

Put opened spools in a gasket bin, a vacuum bag, or a cereal box with desiccant. A dry box holds filament after it is dried. Drying temperatures live on the drying guide, not in these storage threads.

Seal opened spools with desiccant, and dry them on the schedule the product actually lists. [Drying](/answers/drying) is that schedule. A container is not a dryer.

## What people are using

On [r/3Dprinting 1r9dhbx](https://www.reddit.com/r/3Dprinting/comments/1r9dhbx/) the poster just started, lives in Arizona, and contrasts open racks with airtight boxes. A score-35 comment uses 80 qt Sterilite bins with a gasket seal and desiccant beads. A score-12 comment keeps spools in vacuum bags inside the original boxes. Another score-12 comment says one container holds up to 16 rolls once desiccant packs go in.

On [r/BambuLab 1ug1uxp](https://www.reddit.com/r/BambuLab/comments/1ug1uxp/) the question is opened PLA and PETG. The leading comment uses cereal containers with flip lids, plus printed spool mounts, desiccant holders, and a filament pass-through. A score-16 comment uses reusable vacuum bags for engineering filament at work and leaves PLA in piles at home.

On [r/BambuLab 1bb97vz](https://www.reddit.com/r/BambuLab/comments/1bb97vz/) the poster prefers zip-style bags, named as IKEA bags, with one or two reusable desiccant pucks. A comment uses cereal boxes and desiccant packs on shelves. Another comment leaves filament in the open.

On [r/3Dprinting 16hlz25](https://www.reddit.com/r/3Dprinting/comments/16hlz25/) the question is which dry box to buy. The retrieved comments compare a purpose-built dryer with a food dehydrator and talk about printing walls so the food trays survive. That is a dryer conversation. The temperatures for it are on [drying](/answers/drying).

## The catalog rows

[ELEGOO PLA Basic](/brand/elegoo/pla-basic) is the row here that lists a drying time: 50 °C (122 °F) for 8 hours, stated as 50 ± 5 °C (122 ± 9 °F), with a nozzle of 190–230 °C (374–446 °F) and a bed of 35–65 °C (95–149 °F). [Prusament PETG](/brand/prusament/petg) lists 240–260 °C (464–500 °F) and 70–90 °C (158–194 °F), and drying is blank. [Prusament TPU 95A](/brand/prusament/tpu-95a) lists 220–240 °C (428–464 °F) and 55–75 °C (131–167 °F), and drying is blank. [PLA](/material/pla), [PETG](/material/petg), and [TPU](/material/tpu) are the hubs.

On [r/BambuLab 11j8dhj](https://www.reddit.com/r/BambuLab/comments/11j8dhj/) stock Bambu filament was already in a dry box and the walls were still poor after a tuned k value and flow ratio. The comments talk about outer walls at 50–60 mm/s and pressure advance. [Filament quality](/answers/filament_quality) is the next check when storage was not the defect. [PLA printing](/answers/pla_print) and [PETG printing](/answers/petg_print) are the print guides.

## What the community says

r/3Dprinting 16hlz25 asks for dry-box brands. The retrieved comments talk about the cost of a purpose-built dryer versus a food dehydrator, and about keeping the dehydrator usable for food by printing walls instead of wrecking the trays. r/3Dprinting 1r9dhbx asks for a storage solution. The poster mentions low Arizona humidity and both open racks and airtight boxes. Comments show gasket bins with desiccant, vacuum bags, and a bin for up to 16 rolls. r/BambuLab 1ug1uxp asks what to do with opened PLA and PETG. The leading comment uses cereal containers with printed lids and a filament pass-through. Another uses reusable vacuum bags for engineering filament at work and leaves PLA out at home. r/BambuLab 1bb97vz prefers zip bags plus desiccant pucks. r/BambuLab 11j8dhj is a P1P wall-quality print of Bambu filament that was already in a dry box.
