Filament Dryers (self.3dprinting)

So tried out some PETG for the first time, and the first couple prints went really well. but I believe it's picked up quite a bit of moisture, sitting in the basement.

What's the current recommendation for a filament dryer? there was one on /r/3dprintingdeals a bit back, a Sunlu S2. is the S1 good enough, or should someone who's fairly recreational with everything spring for a S2? I see food dehydrators recommended sometimes, is there anything specific to look for in one?

A food dehydrator or the purpose built Sunlu would work great for this purpose, but in my opinion there are easier procedural ways that don't require additional appliances.

I just keep my spools in a large sealing storage tub with an oven safe tray of loose silica desiccant beads at the bottom. Every few weeks the tray of desiccant gets put through a heat cycle in the oven (about 150-75 for 10-15 minutes) and goes right back in the bin. You really only have to fight the moisture that gets absorbed by the spool while on the printer before going back in the tub, and the moisture within the air exchange every time the tub is opened.

Keeps my spools nice and dry without much fuss.

I do something similar. I keep mine in large zip lock bags I got from Ikea with the desiccant packs that came with the spool. These spools then all go in a large Rubbermaid container (which holds 13 1kg spools) so they're doubly sealed and all packed neatly in one place.

This, but I use Damp Rid, which is quicker to replace and not that expensive.

Also, I have an Inkbird temperature/humidity sensor in there to check the status without opening.
