DampRid Moisture Absorber Hi-Capacity Bucket, 4 lb., Fragrance Free, For Fresher, Cleaner Air in Large Spaces, Lasts Up To 6 Months, No Electricity Required

I have two recent purchases, a car and a small home. Both of them came with water issues - stains on the ceiling, inexplicably wet floorboards. Finding and fixing the leaks is great - but then you have a water-tight space that's clammy inside. Enter DampRid Hi-Capacity. I made faces at it on the computer screen. RV-size? But I live here, I don't vacation here! Give me something that works. My secondary concern was that I have pets - wouldn't they get their snouts in there and eat the stuff? I took a chance, seeing as it was less expensive than buying 200 pairs of shoes with those little silica gel packs to absorb moisture. I bought two buckets. I'm SO happy I did. Why? 1. The bucket is full of calcium chloride, a kind of salt (not table salt! that's sodium chloride.do not eat this.) which does, in fact, absorb moisture. You know how humidity makes your salt shaker clog up? This is based on that property, but on a much larger scale. 2. Once you take off the plastic lid, there's paper sealing the bucket. That stays in place during the whole time you use it! The crystals in the bucket absorb moisture through it. So, no spill, no risk for kids, no pets foraging. 3. The bucket has an indicator for when the crystals have reached capacity. Just look at the dots on the bucket to see if it needs to be replaced. 4. It worked in my car and in my house. I set one bucket in each space, and all of the funky wet spots cleared up. I don't have to worry about mold anymore, or sagging ceilings. (As I said above, I fixed the sources of the leaks. DampRid helped extremely well in the drying process. I will still have to paint over the water stains, but I'm confident they aren't wet.) A couple of novice recommendations. I have no scientific proof that these suggestions work, but I believe they were true for me: 1. If using DampRid in your car, check the "vent/circ" button. While you're driving, you may have your vehicle set for fresh air ventilation, and that's fine. But when you park for the night or a long period, it seems to me, it's better to switch the setting to recirculate the air within the car and the dehydrating bucket, closing off the vents. Maybe you could leave the ventilation system open, but that feels to me like turning on the air conditioning while the windows are open. Why waste the bucket dehydrating outside air? Let it suck up only the internal moisture. 2. Don't buy these to store for later use. The bucket and the lid, eh, they match up in a seal that seems tight. But they're probably not made specifically by this company for this purpose. A little at a time, the bucket contents will crystallize with moisture. It's that good. Buy them only when you need to open them. 3. This is an odd one. There's another thing that I found uses the buckets fast: proximity to cat litter boxes. Sure, the cat litter is going to absorb the moisture eventually, but the DampRid is better at it. So, you have two choices ... use the DampRid in the cat area to multiply the work of the kitty litter, or let the litter do its own job and place the bucket where you need other moisture absorbed. Personally, I'm doing both - I've dried out the closet, the bathroom with the vent that leaked, and with the remainder of the bucket I can keep unsavory smells from leaching out of the cat area. There are all sizes of this stuff, but for me, it was cheaper to buy the big one and move it from room to room until it was done. You don't need to move it - I didn't touch the one in my car - but it's common sense to apply the solution to the problem area. I highly recommend it.

Have stored a lot of crafts and family items in cargo container. I use damp rid to control moisture. Works well. Have used it for 2 years and no moisture damage.

I cannot believe how well this works. Our master suite is around 700sqft (bedroom, walk in closet, wide hall, large bathroom). Since it's off the kitchen, we keep the door shut because we cook all the time. For whatever reason, our ductwork doesn't cool it properly and it's about 10 degrees warmer than the rest of our house. Living in Florida, it's very humid here, resulting in stale, moist air that smells dank. Just two hours after opening the tub and placing it in our room, we notuced it smelled fresher and the air felt drier. I am so happy that I just bought 3 more tubs! I got unscented because synthetic fragrances give me migraines and I haven't had any trouble, however I have an uber strong nose and I smell the charcoal. It's not bad at all though, and I doubt anyone else smells it. Great product, highly recommended.

Works but a bit expensive!

This was perfect for my basement! I couldn’t believe how much water was sucked up!!!

This stuff works great! Do you use an open box of baking soda in your refrigerator to keep odors from forming? Same concept here. Although many use it during boat or RV storage, I use it every summer in my boat as well. When the boat is not in use it is sealed up with the mooring cover making the interior a perfect place for condensation cycles that allow mildew to form. This product effectively reduces the humidity in this confined space eliminating condensation cycles in that space which can cause corrosion of metal parts and odors related to the formation of mildew. I place a single container in the space between the cabin sole (Interior floor of boat) and outer hull (Inside bilge/storage area) and let it absorb any moisture caused by high humidity or the storage of damp items in that space. I generally go through about 3 of these containers in one season (4 months). I don't see any reason why it would also not work in the main cabin area for those with larger boats and "Cutty"or "weekender" style boat cabins. It is an odorless solution to eliminate high humidity on confined spaces. This is a very cheap solution to keep odors and mildew at bay in confined spaces that get little or no natural air circulation.

We have a utility room at the back of our house where I store my riding mower, tools, and other items. The HVAC system provides some dehumidification but not enough. A couple of years ago I noticed a good amount of musty smell. I investigated and sure enough we had some mold growing on some things. After I thoroughly cleaned off those items I placed one large container of Damp Rid in that room. I've not had any problems since. One bucket lasts for about 3 or 4 months. I'll continue to use it and recommend it.

I have purchased 8 of these... and 7 of them arrived so badly disturbed/shaken that I had to tear open the protective film, reset the tray, and pour the damp rid product back on top...otherwise it wouldn't work properly. Some of of us remember how it used to be; you poured the product on top of the tray, it would capture/dribble moisture down through its holes into the trap container below, pour out liquid, repeat. Now, they these arrive pre-packaged, I guess to make it safer? with a paper like film on top. Well, that is all fine and good, except for the shipping process. I don't know how the 1 out of the 8 made it intact, but the rest were so bad that I worried that it the mixing of the top/bottom reagents would ruin the process. One tub was crushed so badly that product was pouring onto other things in my box... it was a real mess. These big tubs not only have a huge amount of damp rid product on top of the plastic tray... but some sort of absorbant material in the 'catch' tub below...I guess that is to prevent overspilling? Sketchy if you ask me. These WILL MIX during shipment, the tray will become unseated, and the whole thing could become compromised. (Mine did 7/8 times). I am watching mine closely... all 8... because with this freakish hot/humid weather my house needs help. I will update if the tub spills over like other reviewers noted.
