These seem to do the job there we creted to do.
I have these in a vac bag and see to help keep the filament dry. I really need a longer test, but the cards that come with them has not changed colour to warn me of high humidity.

A bit pricey but a reusable luxury
These are awesome. They work great and definitely keep the humidity in check in my filament bags. I really like that they are infinitely reusable as I’m not a fan of one time use consumables when I can get away from them. The moisture indicating strips that come with them are junk. they are all over the place so I threw them out and manage humidity with a hygrometer. They are definitely a bit pricey and I have had them not fit in one of my filament spools but overall I’m really happy with them.

they don't fit inside of my Prusament spools
measure your spools first. I just assumed they would fit all spools. NOT
