100g Rechargeable Desiccant Pack of 5 - Moisture Absorbing Bag - Desiccant Dehumidifier for Storage Bins and Totes …

So far so good in my 18x18x12 plastic totes! It’s easy to read the indicator that shows when they need to be recharged. It has been raining and super humid since I started to use these about a month ago and so far they still haven’t needed to be microwaved!

Works well at first. But after a while it gets quite ratty, and doesn’t really get back to normal no matter how you follow directions. It did it’s job better than it should have (I’ve had larger disposable ones do worse), however, I will not be buying again.

Have had this now for about 6 months. Would definitely purchase again. The desiccant is within a more durable pouch than what I’ve seen. Much better than the paper product. Would highly recommend

I bought these to help with humidity and moisture in my safe. I was especially excited about the fact that you can recharge them after they are used up as I dont like just throwing away the used silica packs that people typically use. These were larger than I usually use but I think thats a bonus as they will probably be able to absorb a lot more moisture before needing to be recharged. I havent had them very long so I cant comment on how quickly they get filled up, but they are super easy to use, rechargeable and large enough that they should absorb quite a bit of moisture. I think they will work perfectly for what I need them for.

12/29/22 To my absolute surprise these actually work really well. So Im about to give the general times and conditions for my testing so take them with a grain of salt. Over the last two weeks about I left three of these outside in separate containers with approximately 200 gallons of volume. One container does not have a weather seal/stripping and the others do. Their stripping covered the contact surfaces around the lid when fully closed(they were designed and market as weather resistant). The temps have ranged from 16 degrees F one night to 52 degrees F another, with varying rain and snow. And yet the indicator on the non sealed containers was only changing from blue to pink. Considering the condition and extreme wetness this desiccant did a great job of keeping everything within dry. The containers (other 2) were still clearly blue on the indicator and did not need to be microwaved to release the moisture and reset the desiccant. Will update if anything major happens.

Fits perfectly inside filament spool and inside Sunlu filament dryer.

Seems to be working and cant complain about a great price

I used the desiccant to preserve a few cartridges which had primers until I needed to reload them. Nothing like a scientific test but Id bet it did the trick. Don

The blue square bled out so its no longer an effective indicator. After several days, this was not full & there was still lots of moisturecondensation.

Using for my 3D printer filament. The directions to recharge are printed right on the pack, so ill never lose them. Seems to be holding the box steady, great product so far.
