Polymaker H/PolyDryer™ Box/

You do need to already have the accompanying dryer but if you already do you can use these for storage

Bonjour, J’ai commander 4 Polymaker Polydryer Box, en occasions et donc à prix réduit. Je reviendrais encore sur les occasions, c'était la première fois. Franchement tout est irréprochable, ils sont tout simplement neuf.

The PolyDryer system is a total game-changer for anyone tired of the constant battle against filament humidity. The standout feature is undoubtedly the modular design; unlike traditional dryers that pull double duty as a single-spool feeder, this system allows you to decouple the drying unit from the storage containers. Being able to purchase additional sealed storage boxes means you can dry a roll, snap the airtight seals shut, and move on to the next one without leaving your filament exposed to the air. It’s an incredibly efficient workflow for those of us with growing "filament graveyards" who need a scalable way to keep everything crisp and print-ready. The build quality of the storage boxes themselves is impressive, featuring robust gaskets and secure latches that inspire actual confidence in their airtight claims. They aren't just passive bins, either; the integration of a built-in hygrometer and a dedicated desiccant compartment turns each box into a high-tech fortress for your PETG or Nylon. Having a fleet of these boxes allows for a "set it and forget it" mentality—you get the professional results of a dry box setup with the flexibility of a modular library.

Outstanding product. Packaged very well and secure for shipping. Printing mostly PETG, they keep my filament in a perfectly workable state after dehydrating. The digital hygrometer is very responsive and accurate enough for the use case give or take 1-5%. They are nice and compact fitting nicely on shelving for storage. I am a little worried about the clamping sides as they are slightly tough to snap on and engage. Putting the lid on slightly wrong may result in breaking those clamps. I would keep an eye on this. The filament holes on the top and front are great for their use case. I look forward to purchasing more of these as my color library continues to grow. Highly recommended 5 Stars.

These dry boxes and drier work great. They keep my PLA filament down to 10% humidity. The fact that I can use the storage box to hold my smaller spools that don't fit well in my AMS is great. I can hook the box directly to my printer and feed the filament from it. I had one warped box, but Polymaker customer service was quick and great. They provided me with a new box and also gave me printing tips for new material. Highly recommend Polymaker .
