What filament dryer should I buy?

How to use this number

1. The dryer can handle a filament only when the maker's drying maximum is at or below the dryer setting.
2. Filaments with no drying temperature are left out. They are not counted as handled.
3. This catalog has no dryer to rank. The dryer tool checks a maximum against the same filaments.

Each figure comes from the maker's own drying instructions. This is not a dryer recommendation.

A dryer has to hold 50 °C (122 °F) for 8 hours to meet Bambu PLA Basic, 55 °C (131 °F) for 6 hours to meet PolyLite PLA, and 100 °C (212 °F) for 10 hours to meet Fiberon PA6-CF20. Buy a dryer for the hottest spool you will actually dry, then keep the spool sealed. Drying is the material bands and the warning about ovens. Storage is the box after the cycle. Wet filament is how a spool tells you it took on water. Oven and dehydrator drying is the closed-box problem.

Temperatures a dryer has to be able to hold

Bambu PLA Basic lists blast-oven drying at 50 °C (122 °F) for 8 h on the technical data sheet checked 14 October 2026. The same note records an X1 heatbed cycle at 60–70 °C (140–158 °F) for 12 h. PolyLite PLA lists 55 °C (131 °F) for 6 h on the product page checked 14 October 2026. Fiberon PA6-CF20 lists 100 °C (212 °F) for 10 h on TDS V1.1 checked 21 October 2026, with a nozzle of 280–300 °C (536–572 °F) and a bed of 40–50 °C (104–122 °F). The spread is the point. A dryer with no published maximum cannot be checked against these three lines.
