Major Brands & Where to Buy Them
General Retailers
If you let me know what specific filament type you are trying to dry (e.g., standard PLA, PETG, or hygroscopic engineering filaments like Nylon) and your budget , I can recommend the best style of dryer for your setup.
Yes — there are quite a few good options, from inexpensive single-spool dryers to multi-spool systems. ### Good options - **SUNLU S2 Filament Dryer** - $44.99 (SUNLU)
Yes — there are quite a few good options, from inexpensive single-spool dryers to multi-spool systems.
SUNLU S2 Filament Dryer - $44.99 (SUNLU)
Creality Filament Dry Box 2.0 - $35.99 (B&H Photo)
ELEGOO H1 HT Filament Dryer - $70.00 (ELEGOO US)
Polymaker PolyDryer - $79.99 (Best Buy)
Chitu Systems FilaPartner E1 - $138.99 (Chitu Systems)
PrintDry PRO3 - $268.00 (3D Printer | Raise3D)
Budget / single spool:
— about $45 and a straightforward choice for PLA, PETG, TPU, etc.
— about $36, with heated drying and humidity monitoring.
— reaches 85°C, useful if you're drying more demanding materials.
— combines active drying with an airtight storage box; additional boxes can share a drying dock.
— four-spool capacity.
— two-spool dryer with a larger chamber. PrintDry also sells vacuum-sealed storage containers.
matterhackers.com carries several brands, including Creality, SUNLU, PrintDry and Polymaker.
printdry.com sells both active dryers and sealed/vacuum storage.
us.qidi3d.com has a simple sealed, desiccant-based box for about $29–$39.
One important distinction: if your filament is already wet, get an actively heated dryer. A passive dry box with silica gel is primarily for keeping already-dry filament dry. Even Prusa recommends pre-drying particularly moisture-sensitive filament before putting it into its drybox.
If you tell me which filament you use (PLA/PETG/TPU/nylon/etc.) and how many spools you want to dry at once, I can narrow this down to the best 2–3 choices.

If you let me know which filament types you are printing with (e.g., standard PLA, or wet-prone materials like Nylon, TPU, or PETG) and how many spools you need to dry at once , I can recommend a specific model that fits your workflow.
Absolutely. I found several good options currently available: - **SUNLU FilaDryer S2** - $44.99 (SUNLU) - **Creality Space Pi Plus** - $89.99 (Best Buy)
Absolutely. I found several good options currently available:
— about $45, heats to 70°C, and you can print directly through the dryer. Good starting point.
— about $90, holds two 1-kg spools and reaches 70°C.
— particularly nice if you want the box to remain a sealed storage container between prints.
— dries four 1-kg rolls simultaneously and has multiple feed-throughs for printing while drying.
or
— better choices if you're routinely drying nylon, PC, or carbon-fiber engineering filaments.
My pick for most hobby printers: the SUNLU S2 if you have one printer, or Creality Space Pi Plus if you want two spools at once.
One important distinction: if your filament is already wet, get an active heated dryer. A passive dry box with silica gel is excellent for keeping filament dry afterward, but isn't a substitute for actually drying a moisture-loaded spool.

Absolutely. Since you're in Ontario, there are several good options available in Canada right now. ### Good filament-dryer choices - **SUNLU S1 Plus Filament Dryer** - $40.27 (Amazon CA + others)
Absolutely. Since you're in Ontario, there are several good options available in Canada right now.
SUNLU S1 Plus Filament Dryer - $40.27 (Amazon CA + others)
SUNLU S2 Filament Dryer - $65.00 (SUNLU + others)
Creality Space Pi Filament Dryer - $55.46 (Creality CA + others)
Polymaker PolyDryer - $39.99 (Voxel Factory + others)
Sovol SH02 Filament Dryer Box - $76.99 (Amazon CA + others)
SUNLU FilaDryer S4 - $189.99 (Amazon CA + others)
SUNLU S1 Plus — ~$40–55 CAD: Probably the best inexpensive starting point. It handles one spool and reaches 55°C; SUNLU specifies adjustable 35–55°C operation.
SUNLU S2 — ~$65 CAD: A step up, with better circulation and temperatures up to 70°C. Good for PETG, TPU and more moisture-sensitive materials.
Creality Space Pi — ~$55–70 CAD: Another solid single/two-spool option with good user ratings.
Polymaker PolyDryer — ~$40–80 CAD: Particularly nice if you want to dry, store and print directly from the same sealed box. The system uses a drying dock plus sealed storage boxes.
SUNLU S4 — ~$170–190 CAD: Worth considering if you routinely have several spools wet. It can dry four 1-kg rolls simultaneously and reaches 70°C.
Canada Computers currently lists the SUNLU S1 Plus at $49.99 CAD, with some Ontario store pickup showing availability.
Polymaker Canada sells the PolyDryer system directly. The standard box holds up to 1 kg, while the newer XL box accommodates spools up to 3 kg.
DigitMakers also carries the Polymaker PolyDryer in Canada.
If you're mainly printing PLA/PETG/TPU, I'd get the SUNLU S2 or Polymaker PolyDryer. If the problem is really wet filament—especially Nylon, PC or TPU—I'd lean toward a dryer capable of 70°C+ rather than a passive dry box.
One important distinction: a dry box with desiccant prevents filament from getting wet, but it doesn't necessarily dry already-wet filament. For your current failed-print situation, get an actively heated dryer first; you can use a sealed desiccant box afterward for storage.
If you tell me which filament you're printing (PLA, PETG, TPU, Nylon, etc.) and your approximate budget, I can narrow it down to the best 2–3 choices available in Canada.

The manufacturers sell directly: SUNLU filament dryers, Creality filament dryers, and Polymaker PolyDryer. You can also find these at retailers such as Best Buy and B&H.
My pick for most hobby printers: the SUNLU S2 if you normally print one spool at a time; the PolyDryer if you want the filament to stay dry while stored and during printing.

MatterHackers filament dryers carries a broad selection including Creality, SUNLU, PrintDry and PolyMaker.
PrintDry makes dedicated dryers and vacuum-style storage containers.
For local Atlanta-area shopping, the search found several 3D-printing businesses, including ZhumeisterLabs in Norcross and PaliProto 3D Printing in Marietta. I'd call first to verify they actually have dryers/boxes in stock rather than just filament.
My pick: If you're dealing with recurring moisture failures, I'd spend ~$70–80 on an active heated dryer that can also feed the printer, rather than buying only a sealed desiccant box. For nylon, TPU, or other particularly hygroscopic materials, I'd prioritize a dryer capable of higher temperatures.
If you tell me what filament you print (PLA, PETG, TPU, nylon, etc.) and your budget, I can narrow it down to 2–3 models worth buying.
