I personally prefer the PolyDryer system. In the US is about the same price, but in Brazil, it's apparently double on Amazon. The advantage of the PolyDryer is that the dryer itself is independent of the box, this allows you to use the box as storage for your filaments (or print from it) while the dryer is drying other filaments. You can also use cereal boxes alongside this system to reduce the cost of acquiring boxes, and you can also find a lot of accessories for it on Printables and Makerworld. You can also find them on Temu and AliExpress, maybe it's cheaper that way from Brazil. Also, check the Snapmaker site, as they also sell directly there.

Let's go back to the question. For most filaments, you don't need to print directly from the box, you just need to dry it, put it on the printer, and it will print just fine. Now, you have 2 main options, either you print directly from the dryer, or you have a separated dryer and print directly from the printer. If you want to print directly from the dryer, it's fine, it will work, but if you are using it to feed filament, you can only dry what you are printing, you can't dry the next filament you are going to use. These also cannot be used to store filaments, both because you are using them, and they are not sealed. What I'm doing is actually using the PolyDryer system. I don't exactly recommend my current usage, because I'm printing directly from the PolyDryer boxes, but my case is more space related. My suggestion in this case is for you: to pick 1 kit of PolyDryer/Box that costs, right now, $80. This will be your main Drying element. pick cheap boxes, like these specific for 3D Print filament, or you can pick cheaper airtight cereal boxes. These will be your most used filaments that need to be dried. later on, you can pick a couple more PolyDryer Boxes (without the dryer) that costs around $29. These are so you can print directly from there. Another option is just DIY those cheap boxes into similar containers (just put some roller and drill a role and you are good). So, you dry in the PolyDryer and put it here for storage.Then, for long term storage, you can buy any plastic box that is airtight, like this one as an example. This system is a bit better overall because it gives you the flexibility of having the Drying element free and able to dry anything that you need to dry, at the same time, you can expand it indefinitely and even print from it, in case you need that specific usage.
