Damp filament strings and pops, and a dryer is cheaper than a failed print · review
A single-box filament dryer with an adjustable 35 to 55 °C range, a 1 to 99 hour timer and a built-in fan, sized for common 1 kg spools and able to feed the printer while drying.
The bottom line A clearly described entry dryer: temperature range, timer, fan and feed-through are all on the page. Its 55 °C ceiling defines what it is for, and the listing is honest enough to name only the filaments that fit under it.
Five bullets: a built-in fan for even heating that keeps moisture out of PLA, PETG, TPU and other filaments; drying while printing with no waiting time; an adjustable temperature of 35–55 °C and a drying time of 1–99 hours, suited to most 1 kg filament types; a 2 inch LCD showing temperature and time, with operation under 10 dB; and better layer adhesion and smoother surfaces, even in high humidity.
55 °C covers PLA, PETG and TPU. Those are the three the title names, and the page does not stretch the list. Nylon, polycarbonate and other hygroscopic engineering plastics generally need a higher drying temperature than this box reaches.
Temperature and time. There is no humidity sensor described, so the display confirms the settings rather than whether the air inside is dry. A separate hygrometer answers that question.
The second bullet says the dryer works during printing. For a long job on a humid day, that is the feature that keeps the last metres of a spool as dry as the first.
At the last look-up, the German, French, Italian and Spanish Amazon stores were asking 40 € to 45 €.
It is sold in the American and British Amazon stores as well, in their own currency, which the euro figures above leave out on purpose.

Its published maximum is 55 °C, and the materials it names are PLA, PETG and TPU. Nylon generally needs more heat, and the filament maker’s drying temperature is the one to check against this ceiling.
The fourth bullet states under 10 dB. The listing does not say how or at what distance this was measured.
Up to 85 °C · two independent 200 W chambers · four 1 kg or two 2 kg spools · silicone-sealed · touch interface with drying scenes · lit window
The dearest dryer here, holding four 1 kg or two 2 kg spools in two independently heated 200 W chambers up to 85 °C, with a silicone seal to keep filament dry between prints.
Best for: A heavy user storing and drying large 2 kg spools of engineering filaments between prints.
