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

I use this in a Plano sports trunk that I store my 3d printer filament in. I added a gasket around my tote to make it air tight and tossed this in there to keep my filament dryer while being stored. Since filament is susceptible to moisture this has really helped my prints come out perfect everytime! I have t recharged it yet but if I run into any issues later I will update here. So far I highly recommend.

Product was delivered in a very timely manner. Seems to be a great product but will not know until use. Great overall experience with this merchant though.

These work great for long, or short term use.

Good Price

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!

I like that they are rechargeable so that don’t have to keep purchasing. So easy to use. Just put them in the microwave to recharge.

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

Exactly what I needed!

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.

I slipped two of these in between the plastic sheeting and the glass when when sealing the windows for the winter. (We are in an apartment that has dual-glazed windows, but the seal on one of the larger panes has failed and so its like having a single pane window - basically an open refrigerator door in the room during the winter! I put the packets in hoping that theyd take any moisture out of the space so I wouldnt have black mold growing in there from condensation of any moisture trapped in the space when it was sealed. I can happily say that there is absolutely no trace of condensation inside the airspace at all, and definitely no mold at all! Im thinking I probably could have done well using only one, in hindsight. The only reason I didnt rate durability is that we havent had them long enough to let you know that.
