wisedry 4 x 500 Grams [4.4 lbs] Rechargeable Silica Gel Car Dehumidifier, Microwave Fast Reactivated Desiccant Packets Large for Gun Safe Closet Basement Garage Storage Moisture Absorber Bag Reusable

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...

These seem to work well. I placed them inside my windshield on the dash. Really seemed to help with condensation. But only near the area they were placed. Had the windshield resealed. Seemed to be the biggest help. Not sure how much moisture they absorbed. Never did feel damp or soggy. Did use the microwave to dry them out. Will keep working with them and give an update if anything changes.

I put 4 of these in my 10 year old Full size SUV and within 24 hours, the inside of the truck smelled like new!. Also, on rainy wet days with a wet dog inside, the windows no longer fogged up. Couldn’t believe it. They lasted for about 4 weeks then needed to be recharged so I bought a second set of them so I have a set in the truck and a set waiting to be recharged. I used the oven method to recharge and they really do recharge back to orange from green.

I bought these Wisedry silica gel desiccant packs to protect camera gear, clothes, and storage bins — and they’ve worked flawlessly. The moisture-indicating beads are a brilliant feature: the color change shows exactly when they’re saturated and need recharging, so I’m never guessing. Amazon +1 ✅ What I Loved: Absorbs moisture very effectively — keeps storage boxes, electronics, and fabric dry and free from mildew or musty smell. Wisedry +1 Color-indicating beads (orange → green/dark) make it easy to know when to recharge. Wisedry +1 Reusable — once saturated, a quick heat-up in the oven or microwave restores their dryness, so they’re cost-effective long-term. Wisedry +1 Non-toxic and food-grade safe (when labeled accordingly), so safe to use around stored food, clothes, documents, tools, and more. Walmart.com +1 ⚠️ What to Know: You have to remember to recharge them when the color changes — neglect means they lose effectiveness. In very humid or large storage environments, you may need multiple packs to keep moisture under control. ✅ Final Verdict: If you want a dependable, reusable moisture-absorbing solution for closets, storage bins, electronics, tools, or even food storage — these Wisedry silica gel packs are a smart buy. They’re effective, easy to monitor, and give real value over time.

Bought 1 package of 2 500 gas. Used them in storage bins in basement for out of season clothing. So far so good. Just brought bins up and packs do need recharge. I would call pellets more black than green...or a VERY dark green. Anyway none of the clothing smelled musty. I recharged them, but also weighed them to be sure they were to original weight ( as per web site 520-530 gms.

I use these in a rooftop tool chest. They work great!

These work really well, have recharged them a couple of times now so they are definitely pulling moisture out of the boxes I use them in. No signs of mold or mildew on my stored leather items (leather is always the first to go) so I'm pleased.

So far working well. Small size out of the way. Compact. Good value

Condensvanger in de California koelkast

My car stopped fogging from the inside overnight

Los uso en recipientes de plástico herméticos, de entre uno y dos litros de capacidad, donde guardo objetivos fotográficos. Con unos higrómetros controlo el nivel de humedad y consiguen bajarlo del 65 al 30% en pocos minutos. Probé otros más económicos, de otra marca, que no me funcionaron en absoluto, pero estos me están yendo perfectos. Falta saber cuánto durará el efecto, pero, de momento, genial.

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 :)
