Best Filament Dryers: Creality SpacePi & CFS 2, Sovol SH03, Anycubic ACE 2 Pro (2026)

Wet filament causes stringing, popping and brittle parts. PLA tolerates it, but PETG, TPU, nylon and PC need drying, and nylon can pick up moisture within hours. Dryers differ mainly in how hot they get (nylon and PC want 70–85 °C), how many spools they hold, and whether they can feed a printer's multi-color system while drying. Seven dryers from Creality, Sovol and Anycubic, compared on their spec sheets.

Buying guide: how to choose the right filament dryer

Match temperature to material

A 50 °C box keeps PLA dry; PETG and TPU want 60–70 °C; nylon, PC and carbon-fiber nylon need 75–85 °C.

Drying vs storing

Drying drives out moisture; sealed storage with desiccant keeps it out. Several units do both, and the Creality CFS 2 also dehumidifies during printing.

Multi-color units are brand-locked

The CFS 2 works with Creality K2 printers and the ACE 2 Pro with Anycubic Kobra printers. Standalone dryers work with any printer.

How this ranking is calculated

Score = weighted average of normalised specs, out of 10. Full method

Max drying temperaturePLA dries around 50 °C; PETG, ABS and TPU want 60–70 °C; nylon, PC and PA-CF want 75–85 °C. Scale: 50 → 85 °C.

45%

1 kg spools heldHow many standard 1 kg spools fit at once. Scale: 1 → 4 spools.

25%

Dual independent heating zonesTwo chambers at different temperatures, e.g. PLA and PETG at once.

15%

Works as the printer's multi-color feederYes for units that both dry and feed a printer's multi-color system (CFS 2, ACE 2 Pro). Standalone dryers can still feed through a PTFE tube.

Frequently asked questions

Can I dry filament in an oven?

It's risky: plastic spools can warp. A dedicated dryer is built to hold a low set temperature for hours.
