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

I bought these to put in a safe and then realized how many other places I could use them. They are easy to use and rechargeable, I havent had to recharge them yet but directions on back of package seems easy enough. Im very satisfied with my purchase.

I put a few of these in mini-fridges when I ship them for a trade shows since they will usually have some residual moisture, or in full size fridges when I pack up the summer home for the winter. Gives me a peace of mind there will not be any mold when I go to use them in the future.

Reusable, cheap and easy to see.

Fits perfectly inside filament spool and inside Sunlu filament dryer.

Seems to be working and cant complain about a great price

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.

These are great in the refrigerator. Very easy to see when it needs to be”recharged” which is as simple as popping it into the microwave for a few minutes

Great item if you want to get the moisture out of a small area. Just have to remember to dry it out every once in a while.

These desiccant bags are perfect for keeping my filament dry. I bought a five pack though one bag is more than plenty for a small airtight container like the one I use.

I bought these to sit in my air tight pelican case full of nylon and TPU filaments. So far humidity levels in the box are around 8% to 12%. In Room humidity is 44% to 71% (shop in basement). So they are doing their job. I have no complaints so far l.
