wisedry 5 Gram 60 Packs Food Grade Silica Gel Packets, Rechargeable Food Safe Desiccant Packs with Color Indicating Beads, Reusable Moisture Absorbers for Food Storage, Electronics, 3D Filament & Safe

A month ago I never would've guessed the answer to my cars' inside window fogging problems could be as simple as a giant version of the same thing I've seen inside supplement bottles for my entire lifetime. Now I am a believer, and that's thanks to these WiseDry 500g desiccant packs! They worked for me exactly as advertised, including the recharge procedures. I purchased 8 packs and stuck 4 inside each of my problem children (vehicles, that is). The benefits played out over several days. I did need to wet vac out the pooled water in one of them to get maximum benefits from the packs. But the result over 4 weeks of constant usage is obvious--highly reduced condensation on the inside back and front windows of the two cars! In a wild, woolly, WET Pacific NW winter, that is an AMAZING result! I did discover the microwave is not a very efficient way to recharge all 8 even 2 at a time. It took these packs about 5 days to suck up enough moisture to go "full bloated" (650g weight or more) and following the instructions it would've taken a couple hours all told to get all back down to 505g +/- new weight. And that process pretty much required constant attention. I was actually concerned about the workout it gave my microwave, which isn't used to more than 20 or so minutes of use at a time. So I tried the oven method and was more satisfied using that for these packs. Keeping the oven temp below 300F it still took 6 1/2 hours to get all 8 packs down to recharged weight, but it was a completely hands off process. I don't have an easy way of measuring the energy use of my oven, but I wouldn't be surprised if cost was a wash due to the lower KW needed by a 240V appliance to provide same amount of heat as a 120V unit. That's physics so not gonna go there. Anyway, these packs fared well in the oven so that's likely how I'll generally recharge them. All told I'm giving them 5 stars and gonna keep them in mind for ALL my moisture-related problems henceforth. One note about oven recharging: I'm cheap so I order some less expensive versions of these 500g desiccant packs after seeing the results of the WD's--the white ones that look almost exactly like an overblown version of a vitamin pack, in every way, including seam sealing. Whereas the WD's are tubular construction with just very serious heat fused seams on the top and bottom, the cheaper packs have seams on all sides that did look less, shall I say, "sincere." I allowed them that slack since they were, in fact, cheaper and still claimed to be oven-chargeable. sWell don't you believe it!! Of the 6 of those packs I oven-recharged same as the WD's, 4 split their seams and spilled the beads! Would've been a much bigger mess had I not had a baking sheet below them to prevent direct heat from the oven elements. Oven temps were never about 300F but I believe should be kept to a limit of 250F for these packs. Then they seemed fine, but time of recharge would go up as much as several hours. I have yet to try that again--getting my courage back up...

Great product! These absorb a ton of moisture and keep my filament dry. Recharging them is super easy. It is very nice that they change color so I know exactly when they are full and need to be recharged.

Great product for the price.

They're alright. They're doing the job in an environment prone to humidity during a time of very humid weather. I saw that you just had to pop them in the kicrowave for 30 seconds, so I tried it on the first 3 that turned green. Fried em. Yuck. My bad, didn't really read the included information - you have to start with ten of them! And put the microwave on a lower setting. Ah. Oops. Idk if I'll really get these again. Maybe this is where we are going with dessicants, in which case I'll have to get them again eventually. That would be ok. I think I'm figuring out just how easily these packets become saturated and less effective. Not to mention the challenge of keeping my supply dry. Overall, they're working and things will dry up soon, so... I don't hate them, they're a good value especially when they CAN be "recharged" and reused.

An excellent product! I’ve kept two in my car all summer (they fit nicely in the door pockets) and reset them in the microwave three times. They’ve done a great job keeping the interior from getting musty in the humidity.

After one day, the product seems to be performing as advertised. My crew cab pickup truck was getting enough condensation on the windshield to wet the registration and inspection stickers to the point they were coming off the glass. The truck is black and the cabin is cavernous, so there's a lot of area to test this product. I put one 500 gram bag on the dash board and checked it the following day. There's still condensation on the windshield, but not nearly as much as without the bag. I put the second bag on the center console as well as the one on the dash. Hoping to see heavy bags and dry glass tomorrow. But so far, I'm definitely seeing some improvement. UPDATE - 2/4/24 Both bags reside on the dash tray during the winter months now. Doing a good job of removing most of the condensation on the windshield. They're not perfect, but help A LOT. SUGGESTED DRYING PROCEDURE: After reading a number of complaints from others about the bags burning up or forming holes during microwave drying, I experimented with my 900W microwave and found things work better when I **put a folded white paper towel under the bag during heating. It helps draw moisture out of the bags during the microwave drying process. **SET THE POWER LEVEL for 5/6 for 4 1/2 minutes at a time. This setting removes approximately 15 gr of moisture for every 4 1/2 minutes at power level 5/6. --Yes, it takes MULTIPLE cycles to get them down to the original 500 gr weight WITHOUT Burning the bags up. (I'm using a digital scale to weigh the bags - Dry weight - 500 gr, Suggested weight for drying - 650 gr.) **After removing bag from microwave (beware - it WILL BE HOT) place the bag standing on end on a dry towel - preferably in front of a small fan set on "LOW" (to help cool AND blow moisture from the bag). --IF YOU'RE USING TWO BAGS, heat them individually - one cooling while the other is in the microwave. Hope this helps a few folks. EDIT ....at 14 MONTHS of consistent, heavy use (2/10/25) : ***These are still going strong. HOWEVER, around the one year mark, THE BAGS DEVELOPED SOME SEPARATION AT THE SEAMS and leaked some of the tiny silica pearls when I was drying them in my kitchen. I used some cotton thread to oversew the seams that look like the manufacturer originally bonded with a crimping iron or similar device. This is holding well now. ***SPECIFICS: I keep these drying bags on the dashboard of my truck (right next to the "plastic Jesus"), so they've seen a fair amount of direct / filtered UV sunlight and temperature extremes throughout the year. Just suggesting you do a visual inspection with these from time to time before handling them roughly after/around the one year mark - so you don't have thousands of tiny marbles to clean up.

I love this thing! I purchased some collectible coins this year and AI said I should store them in a humidity-controlled environment. I got the tote from Home Depot because it sealed and had an IP-67 rating. I got the wisedry 10-gram desiccant reusable packets to control the humidity. I put each coin shipping box in a heavy-duty zip-loc (which are super nice – very thick) with one wise dry in the zip loc. I put three zip locs with coins in the tote along with a fourth 10-gram wisedry desiccant reusable packet to control the humidity in the tote. Then, I also got a TempPro TP50 digital hygrometer thermometer and put it in the tote. The thermometer and wisedry desiccant packet are clearly visible through the tote so I can see if the desiccant packet needs to be recharged as well as check the temperature and humidity level inside the tote without opening it. Before placing the thermometer inside the tote, I measured the room relative humidity (RH) at about 48%. After I placed the TempPro TP50 digital hygrometer/thermometer inside the tote, closed the tote and waited a day, the RH inside the tote was down to 17% RH! Woo-hoo! Inside the tote is nice and dry and I can monitor the RH inside the tote as well as the status of the desiccant packets without opening the tote. The whole storage system cost under $43 and is doing a great job! Home Depot delivered to my doorstep unboxed and the tote was in perfect condition.

Works as expected including the ability to “redry”. Great for your car or closet.

Ik wilde graag testen of het klopte wat op de verpakking stond en heb een zakje onbeschermd een week in de woonkamer gelegd. In deze tijd kleurde het van oranje naar groen en dit zakje heb ik gebruikt voor mijn experiment. Tussen elke foto zit 1 magnetronsessie van 600 Watt gedurende 2 minuten. Je ziet de inhoud verkleuren van donkergroen naar oranje en het gewicht neemt met 6 gram af. Oftewel: de zakjes nemen 6 gram water op. Een ander zakje heb ik in een waterdichte pelicase gedaan. Deze is na een maand nog altijd oranje en houdt de inhoud van de pelicase droog. 6 gram water opnemen is echt heel veel. De maximale luchtvochtigheid bij kamertemperatuur (20 graden celcius) is 17,3 gram per vierkante meter. De maximale hoeveelheid vocht bij volledige verzadiging in een object van 50 liter is nog geen 1 gram. Ongelooflijk, ik had wel de kleinere versies voor mijn pelicase kunnen nemen :)

Works great. Has many use cases around the house for humidity.
