Wisesorb 3 Packs 40g Indicating Silica Gel Dehumidifier Desiccant Tin Canister, Wisetin Orange to Green Color Changing, SG-40 No Cobalt (II) Chloride-Reusable (40g) (Pack of 3)

The only thing that’s a little annoying is how often these need to be recharged in the oven (I live in Seattle). Other than that they’ve worked great!

These are working as described and are very useful - especially the way you can put them in the oven to refresh them.

These are indispensable. I like to keep them around- you never known when they’ll be useful.Get your phone wet? Turn it off and put it in one of these canisters for a few hours and watch the water as it’s pulled out and into the silica.Damp smell in a pantry? Or a fridge? Or even a freezer? These are a big help in all kinds of unexpected situations.Anecdotally, they’re even helpful in biochemistry to accelerate liquid reduction in a contained environment (like a vacuum chamber). The color changing silica can be purchased elsewhere but these aluminum containers are very convenient and the color change is easy to quickly identify at a glance. As well, you can reactivate the silica near indefinitely.I keep three of these in my drawer with batteries, candles and the other things you don’t expect to need but plan for anyway. Murphys Law makes these indispensable.

These little guys work great. I just wish you didn’t have to stick them in the oven for so long

We had a musty smell in our safe and it felt more humid than it should have been- this cleared it up immediately and I love that we can reuse these! Also great because kids and pets don’t think it’s a snack (which the typical other packaging looks like).
