wisedry 10 Gram [30 Packs] Silica Gel Desiccant Packets Reusable for Moisture with Color Indicating Rechargeable Small Dessicant Packs Food Grade

These silica gel packets work great to absorb moisture in small areas, to protect your valuables and important items. I like the fact that you can see when the packets are saturated (orange gels turn bluish purple color), and thus need to be recharged in your microwave oven. Caution: if you try to recharge the packets based on the instructions that come with them, you will end up melting the packets, thus ruining them. What worked for me is setting my microwave oven to 70%-80% power and heating the gel packets for 45 secs to 60 secs at a time. Do this several times, each time checking the packets and drying any moisture that forms under them. Depending on the power of your microwave, the bluish purple gels will start to turn back to an orange color after several intervals of heating. Once the gels are back to an orange color, then the packets are recharged.

Use in all my bags , work well

I have a little lock box for some papers & stuff. Living in the south makes life humid, even with the A/C on. Sometimes opening the box to add/remove stuff I found the insides getting soggy, mildewy and damp. These are the cure!They really do work. No more soggy or damp papers. I haven't tried recharging them yet because I'm a little scared of that process, but I love the color-change alerting me that it's time to change out.Perfect for what I need, I'd buy again. In fact, I did!

Great product that I'm using A LOT right now during monsoon season in Arizona. Very humid right now. They definitely absorb moisture & humidity. I KNOW the colored beads work, because I have 2 packets in my Pelican case & they stay orange, because the seal is so tight. They stay orange a long time if in a ziploc bag, but in a drawer or in my other cases...the beads do change to a dark green. My only complaint, is I have only had success recharging them on one occasion. Would be great to be able to recharge them.

I had never seen reusable dessicant before but these are pretty good. They last awhile and can absorb a lot for a long time. Love the color change indiator as well. I tried cooking/recharging a few and it did work but it didn't last AS long as the initial time, although that seems to be common sense. I just buy new ones when the old wear out because they last so long it's not really a waste of money to just replace them fresh. If you go the recharge route just check on them every so often, as the absorbency time gets a little bit shorter each time you recharge them. Great product though, highly recommended.

We put these in item to be put in the storage building. It keeps the moisture out. And items don’t mildew or smell.

I throw in a couple into every storage bin. Work well.

Being a retired scientist and wanting to keep my bags of corn chips as crispy as possible, I had to find out how effective these packets are at different weights and colors. Of course, the benefit of this product having color-changing pellets is that you don't need to weigh them and instead can use the pellet color as your indicator for how much moisture absorption mojo they have left.For those of you who prefer not to look at graphs, my take-home message was this: If the little pellets have orange or red left in them, then I keep using them because they have greater than 33% of their absorption strength remaining. Once they are mostly green or darker, then it's time to swap them out. Now, feel free to tap that 'helpful' button and peace out.For those of you who do like to look at graphs, check out the image provided. It shows the color variation by how much moisture it absorbed. I left a brand-new packet out for 48 hours at room temperature and 65% humidity. I intermittently recorded the time, weight and color. From those data points, I was able to derive this graph. As you might expect, the absorbency rate decreases as the packet becomes gradually more saturated. This experiment used a 10g packet; the weights and absorption rates would scale proportionally. But color as an indication of absorption strength should remain consistent across products sizes.Enjoy geeking out and please hit me a 'helpful'. It encourages me to do more reviews like this. Thanks!
