I just throw my reusable packets into the dryer with my filament spools. Nothing special.

I use renewable mini dehumidifiers instead.

RE:

I have a re-usable Silica pack in each spool´s ziplock bag, works for me perfectly in German climate. I dry the packs once a year in the oven, getting them down from about 12g to the original 10g weight. I only have about a dozen filament spools in use at any time and some spools have survived for three years. I print in an enclosure which gets warm and thus probably does not add any humidity to the filament whilst in use. Never had any problems with wet filament.

Cheers

RE: Reuse Silca gel to filament 🙂

I bought some bulk silica gel (7.5 lbs) and some small cotton bags with draw strings. I fill each bag about 3/4 full and place 3 to 4 bags in each of the sealed plastic containers  I have for my filament. I put a humid sensor on each of the containers and keep track of the humidity in each container. When it gets close to 30% I gather up the bags and empty them into a paper plate and dry them in my microwave. It only takes about 2-3 minutes to dry them. The silica gel is dry when the color returns to orange. Then I refill the bags and put them back in the containers This lasts for quite a while. Each container is about 30 cm x 30 cm x 45 cm. One is a little bigger. Each container holds about 9-10 rolls of filament.

Printed containers that fit in the spool centers. In my dripping wet climate I pour out the silica into a microwave dish and run on 50% power for 3 minutes, stir it around them three more. The color change indicators show it lasts two weeks or so of use in the filament dryer.

I use a similar system. Only special thing is that my 3D printed containers are made from PC blend, so they can withstand the maximal temperature reached inside my PrintDry filament drier.
