Are we kidding ourselves about desiccant?

I found with plastic bags that over time they can get scratched or torn and will no longer be air-tight. I keep all of my hydroscopic filaments in Polymaker dry boxes with 2 desiccant chambers filled with activated alumina. For the nylon (PA), PC and TPU I'll put it in the dryer before a print even if stored in a dry box. 

How do you dry your activated Alumina?  I have been using the Polymaker boxes.

When the box hydrometer reaches 25%, I dump it out on a baking sheet and put it in a convection oven at 250C for 2 hours.
