Hello, welcome back — I’m Paul from Where Nerdy is Cool, and in this one I’m talking about something that’s way more important than people think: keeping your filament (and other moisture-sensitive gear) dry by recharging your silica gel desiccant packs. I’ve been using those Amazon cereal containers for 1kg spools for years, and I still swear by that setup — but the desiccant only works until it doesn’t. With the Wisedry indicating packs I use, the beads are orange when they’re dry and turn green (or even a weird purplish color) when they’ve soaked up too much humidity and it’s time to recharge them. Normally, the official recommendation is an oven or a microwave, but I’m just not a fan of mixing “stuff that lives with filament” into the same appliances where human food goes — even if the packs are non-toxic and food safe. I’m big on safety (my enclosures have fire safety devices and filtration), so I tested a dedicated air fryer as a mini convection oven. Using the mesh tray for airflow meant I didn’t have to keep flipping packs like you would on a cookie sheet. After experimenting with different times, I found that 120°C with convection for 40 minutes (the max on my unit) consistently brought them back to orange, and it can be a power-saver versus running a full-size electric oven.
