Does DampRid Really Work?

Does DampRid really work?For those of you who have never heard of DampRid, it’s a bucket filled with salt crystals which apparently absorb excess moisture out of the air. In doing this it reduces the growth of mildew and mold.


What is DampRid?

Damprid for Homes

DampRid is a product that contains moisture absorbing crystals to help minimize moisture in

  • Your home
  • RV
  • Car
  • Cottage
  • Boat

or any area where moisture is a problem.

A Good Product History

DampRid products have been on the market for more than 70 years. DampRid also controls odours caused from moisture like mildew and musty odours and stale odours.

DampRid is virtually a wireless dehumidifier, making this product extremely convenient. Many products like candles and sprays just cover up odours, they don’t eliminate them. However DampRid products absorb and eliminate odours. This results in cleaner, drier air.

How Do DampRid Moisture Absorbers Work?

When the DampRid products which contain all natural crystals are exposed to air, they absorb moisture and slowly dissolve into a liquid brine, which is a saltwater solution.

DampRib only traps excess moisture and never dries the air to the point of damaging furniture, animals, plants and clothing.

DampRid works in three phases.

  • The first phase DampRid crystals absorb excess moisture from the air, then harden and form a solid mass.


  • The second phase is when accumulated moisture begins to drip into the bottom of the tub and about half to three quarters of the crystals dissolve.


  • The final phase is when all of the crystals have dissolved and the bottom of the chamber is full of liquid.However if using products which contain scented or fragranced beads a small layer will remain in the top chamber, these can be discarded in the trash and the liquid can be emptied into the toilet.

The DampRid formula is environmentally friendly and septic safe.

Where Can I Use the DampRid Products?

Bathroom Mositure

As DampRid products don’t require electricity these great products can be used anywhere that moisture may be a problem such as:


  • Bathrooms
  • Garages
  • Closets
  • Laundry Rooms
  • Campers and RV’s
  • Basements
  • Kitchens
  • Bedrooms
  • Boats
  • Office
  • Cars and Trucks
  • Transport Trucks

  • Storage Lockers
  • Diaper Pails
  • Garbage Cans

They can be used virtually anywhere.

My kitchen sink overflowed when I left a dirty pot to soak and forgot all about it. My whole floor was saturated with so much water is was truly a disaster.

Seriously though, I vacuumed, mopped, soaked up ….. all the water I possibly could by my whole room area rug covered with both furniture and “stuff” couldn’t get fully dried.

Almost immediately the most nasty smelling whatever started growing and I was getting nauseated trying to steam kill the problem.

Found this in my local hardware store and was told these will both dry out my rug AND remove the smell. I was told to just open the top and place the bucket in the room.

The bucket has more instructions, but after getting home I was so tired and fed up, I just opened the top, saw a tub of white crystals and just lifted the area rug and scattered about half the tub under the rug from all 4 sides.

This stuff is truly awesome 🙂



Lee Keels October 23, 2015 at 6:45 am

No, No…NO….you do NOT EVER take this stuff out of the bucket. If you had really done that, it would have caused a huge mess, so I’m discounting your entire review as fake.


Cam September 11, 2016 at 6:34 pm

It is just CaCl – which does remove moister – so what she did would work really well. I don’t know why you would discredit her review because based on basic chemistry it works… Don’t be indolent.


TrainChaser November 11, 2016 at 9:51 pm

There are two reasons why scattering it loose isn’t a good idea:

1) Salt is corrosive. People who have scattered it on their carpets to kill/repel fleas end up replacing their carpets because they eventually rot (chemically).

2) Salt absorbs moisture… and then gets rid of it. In DampRid containers, the absorbed water goes to the bottom of the container in the form of salt water, which you need to dump out. Under a carpet, where do you think that excess moisture goes? It’s not magic, you know.


Kathy December 22, 2016 at 11:10 am

WRONG!!!!! I agree with Lee. The above review is false. I accidentally spilled one of these refillable buckets and it was a disaster!!! These crystals turn into a silicone-like gel that never evaporates. The crystals spilled on my carpet and I tried to vacuum them up. They began to turn into this gel and ruined my metal vacuum hose. I had to painstakingly absorb each of these crystals into a towel. It is very difficult to absorb a greasy feeling gel. It took over an hour. Disregard “Basic chemistry”. I’m going by experience!


Albert22 November 30, 2011 at 2:43 am

I have used DampRid, I use it in my closet, I have a very humid closet, and my clothes started to get mold! I tried DampRid and it really absorbed the humidity in closet, I have to say it worked for me, but yes, the space I use it is closed and very humid.


Belle Merc August 6, 2017 at 11:37 pm

Sounds good Albert.


Lisa Bishop December 26, 2017 at 4:01 pm

I used the DampRid’s hanging bag in my closet and it really absorbed the humidity; however, so much so that my shoes with glued parts, came apart! That makes me wonder if it really only works above a certain humidity level – seems it wasn’t going to stop once it started.


DJ January 17, 2012 at 8:04 pm

I have no doubt that this stuff works, but why buy a specialist product when standard table salt does the same job?
We have a holiday home that we don’t go to over winter, and for years have always put bowls of table salt in each room and when we go back after the winter the bowls are full of the absorbed water.
Not knocking the product but you can do the same with stuff already in your cupboards.


Belle Merc August 6, 2017 at 11:38 pm

Will certainly try the table salt or kosher salt, have lots of that! Does this remove mold odor??


Steve February 9, 2012 at 5:11 pm

I think you meant to use the term “dehumidifier” in each instance where you wrote “humidifier.”


Kaa May 28, 2012 at 10:49 am

“spit them out due to their fowl taste.” *foul, I don’t think they would taste like chicken.


Mike S October 25, 2012 at 10:07 pm

It just doesn’t work. I went to Home Depot and bought a bucket of DampRid because I had high humidity in cold room and didn’t want to install dehumidifier. My cold room is 80 s.f. and the product claims that it works for up to 250 s.f. area. I was not seeing any results (humidity remained at 70Rh) after 3 days of use, so I called the company and asked whether it works in cold room and at this humidity level. The answer was both “yes” and that it should reduce the humidity to 60Rh, which was my target. The guy told me that it may take up to two weeks before I see drop in humidity and some water accumulated in the little bucket. Well, it’s been 4 weeks and the humidity is still 70Rh and there’s not a drop of water in the bucket. I don’t know whether the stuff I bought is defective (whatever it means for such a product) or the guy at DampRid wasn’t telling the truth. Good thing this is really cheap, but I guess I will have to go dehumidifier route after all 🙁


Richard Hensel August 24, 2016 at 6:30 pm

Try Rita’s Sphere. It actually kills and prevents mold and mildew. Just sayin.


Jeannette February 23, 2013 at 9:09 pm

I’ve been using DampRid for a while, and I thought it was working, but I just checked the bucket in my closet and there’s mold growing on top of the DampRid!! I have a feeling the mold is winning here, and it’s best to just pack up and move!


Jo October 22, 2017 at 1:08 pm

Haha awwww bad luck!


John March 10, 2013 at 3:00 pm

NOT as much as reported: the water in the bag after several weeks weighs roughly the same as the new unused product! I suspect the product does retain some moisture, but far less than advertised.


sallie July 18, 2013 at 12:44 pm

Don’t you mean “dehumidifier”?

“You may find that buying an electric humidifier will work out to be cheaper in the long run.”


Rhonda July 21, 2013 at 3:59 pm

Our living room was flooded from a bad storm we had. I rented a rug doctor to get rid of the odor and smell, but the smell kept coming back. A friend told me about Damp Rid and I went and got one. I put it in the room and the smell was completely gone within a couple days. Damp Rid only cost a few dollars and works great. I put one in the bathroom because the often use of the water and my bathroom stays free from a moldy or musky smell. I would recommend Damp Rid to anyone.


keirra July 31, 2013 at 3:33 am

I get mold on top of the crystals… i ended up buying a hanging one as well as the bucket for my bedroom. i think we are gonna have to buy a dehimidifier…


James August 16, 2013 at 8:57 pm

I have been using DampRid since 2006 in my finished basement to control the humidity. It works very well for me. I just have a problem remembering to check it before it runs out. After a while the moldy smell returns and I remember to check, and its needs changing. Great product try. I hope it does the job for you too! ( No, I don’t work for the company. I’m just a happy customer. Lol!)


jan April 6, 2014 at 6:28 pm

If you put out several buckets inside the house and leave them for 7 months, won’t the collected water just evaporate back into the rooms?


Gary May 31, 2018 at 2:00 am

No – the collected water muxes with the calcium chloride salt to make a brine. The brine is much, much, much less prone to evaporate. The scientific explanation as to why the brine doesn’t evaporate requires getting into thermodynamics – which I doubt you are interested in, but if you are really curious go talk to a physical chemist or chemical engineer.


mary August 28, 2018 at 12:10 am

everyone is saying “in the air” But what about a situation where the Flood – actually flooded the carpet – the carpet people came and “cleaned” when they left the smell was worse then before they got there – 4 days later the carpet is still NOT DRY! Will this product actually help dry the Carpet as well? Im gonna move away too like the other lady said….. and yes there is mold in the corner of the room where the wall meets the carpet….


adrian August 31, 2018 at 11:44 pm

It gets rid of the moisture in the air so when the air is drier the damp in the carpet will more easily evaporate, but that’s only if the room is humid, which I assume it is after the flood.


ina June 9, 2015 at 6:55 pm

Will it do any harm if you take protective cover off & put in my car?


Lee Keels October 23, 2015 at 6:46 am

You know…there’s a reason the cover says “do not remove.” You do as you wish.


me June 14, 2015 at 9:41 pm

It works. I use the hanging ones in my closet and it started to fill with the moisture liquid and my closet started smelling good. No more vintage, musty, moldy smell. I am very happy. It works!!!


sara kavanaugh July 17, 2015 at 1:34 pm




Ashley July 31, 2015 at 9:42 pm

This article seems to focus on the product helping air quality, I have no idea how well it works for that because I am not sensitive to humidity nor do I have any special breathing needs so I probably wouldn’t notice if there was a difference.

But I did have moderate water damage from a broken pipe and at first thought I was going to have to replace the drywall and flooring. The drywall was so saturated that it was very pliable to the touch. But I gave this a try first and it dried it right up, the drywall is solid as new and the laminate flooring is also drying well.

This stuff is like $2 or $3 at the Home Depot and saved me hours of work and a lot of money.


Meredithe McCormick August 17, 2015 at 10:06 pm

We purchased DampRid and followed the directions and put it in my husband’s shed out in the backyard. A few days later when he checked it there was water in the bucket but the “crystals” have turned to a rock. The “rock” will not come out of the bucket. So, what do we do now??


Lee Keels October 23, 2015 at 6:40 am

Read the damn instructions. It tells you CLEARLY that the crystals will harden as it starts to work.


Monica June 25, 2018 at 3:30 pm

Lee why are your responses to numerous people so cruel? Try finding a nicer way to say the same thing.


Rex August 3, 2018 at 2:20 am

I think he’s completely in the correct tone…. how do you freak out about a product when you haven’t read the instructions.


Kathleen July 15, 2016 at 3:54 pm

You can drain the water out of the bucket and keep it in there to see if it will gather more water. If not throw the whole thing away. I used both the bag and the bucket in my closet. I’d change them out whenever the other was full of water. There was no outlet near my closet for my electric dehumidifier and these worked great. Well worth the money spent as I had NO more MOLD in my closet.


Leanne August 26, 2015 at 7:35 am

Firstly it is NOT salt. It is calcium chloride. Same stuff as you use in pools so you could go to a pool shop and buy it in bulk but you will need an airtight container to store it in as any air contains moisture and it will absorb it.

This stuff certainly does work, and if you buy the refill it is cost effective. I bought the generic brand tubs for $2 each and the Damp Rid brand 4kg refill at the hardware store for $17. Much cheaper! All up cost me $27 where if I bought the Damp Rid brand tubs plus a refill it would have been $52! When the Damp Rid is liquid I tip it down the toilet and refill. After a couple of weeks the air was cleaner and less humid. No more damp smell.

The crystals will go hard when the absorb moisture and this will turn into water soon enough, just be patient. It takes around 3 or 4 weeks to see any water in the container.

A tip if you do spill the stuff: wipe up the crystals and you will see an “oily” area, wet it with water and wipe it up. All done. If the spill wasnt noticed for a couple of days you may need to repeat once or twice more.

I read one person here sprinkled it on her floor! NEVER do that! It sucks up moisture like you wouldnt believe and if put on floors or carpets it will make them wet.

I wish we could get the decorator ones here in Australia that I see advertised in the US 🙁


David October 22, 2018 at 3:25 am

Calcium chloride is a salt


Loraine September 16, 2015 at 8:49 pm

I put it in a cardboard shoebox which became wet overnight and again the next night inside a cedar chest that had been stored in a basement


Lee Keels October 23, 2015 at 6:47 am

It sounds like you took the crystals out of the container. Try reading next time.


Loraine September 16, 2015 at 8:52 pm

The cedar chest: Is this normal? Where did all the water come from? The floor was even wet underneath the chest. I HAVE to get the basement smell out of it. Any suggestions?


Kathleen July 15, 2016 at 3:57 pm

Keep buying the buckets until you don’t smell it anymore. I’d suggest getting a few and also the refill so you can dump out the used product and water and reuse the buckets. It worked for me. And worked in my cedar closets.


Hunh?!? September 21, 2015 at 3:13 pm

Loraine: Did you keep the crystals in the plastic container or pour them directly into the shoe box?

The crystals sit on top of a filter and allow the water to drip down into the plastic tub.


Wood in Virginia October 23, 2015 at 3:19 pm

Had one in the POD on my Lawn when we were doing home Renovations. ( Had clothes in that 15 ft POD and wife didn’t want any musty Smells in here closets that had to be emptied & put in pod.

Also have used this in enclosed spaces in Car and Trunk ( using the hanging envelope version) When Sunroof on Volvo clogged and water emotied into passenger floorboard side of car. Had to remove seat & Carpet to get it fully dry but Damp rid helped on days in was only 50 degrees outside And I left Damprid in car with windows closed to get “greenhouse” effect. The ionization of water and these crystals do seem to remove excess water in tight spaces. No wonder the product is patented..


sheryl December 5, 2015 at 4:19 pm

Does this work good in campers


Kathleen July 15, 2016 at 3:59 pm

Yes, my aunt had an enclosed camper and she always used this in the bucket form and in the hanging bag form. She never had mold, it just smelled damp if she didn’t use it. Her camper smells great all the time.


Cynthia January 4, 2016 at 9:44 pm

I use it in my closets where there are no electric outlets. As long as I keep up on them, they work well for me. The few times I forgot, I got mildew fairly quickly and had to resort to wiping down my non-washable items (like shoes and leather items) with vinegar and tea tree oil.


Donna February 2, 2016 at 4:29 am

I put damprid starter in to a linen cupbaord

Should it leave a salty taste in your mouth and on clothing and skin.


Donna February 2, 2016 at 5:10 am

I put damprid starter 300g in to a linen cupbaord today that is not air tight and it is in the bedroom so when I go into the bedroom it leave a salty taste in your mouth and on clothing and skin and now the covers on and pillows have a salty taste. Should this happen and is it dangerous?


Kathleen July 15, 2016 at 4:02 pm

My closet and the clothes in it never had any saltiness in it or on my clothes. Then again, I never licked it.


Valeria Buck May 9, 2016 at 1:43 am

I had damprid leak in my closet. My leather moccasin, which was handmade for me by a seminole friend, absorbed it. Now it is stiff and deformed. Is there a way to remedy this?


Karen E Rizzuto June 5, 2016 at 3:57 pm

I didn’t know the damprid could grow mold on it


Bill July 4, 2016 at 7:06 pm

“.. the crystals should not be inhaled and avoid contact with eyes, it also states that it can cause nausea. But these crystals aren’t meant to give off any gases or fumes, so why can’t you inhale them? If they’re completely safe for pets and children, why do they cause vomiting and why can’t they be inhaled?”

Are you seriously asking these questions? Do you know of any salt that you are not supposed putting into your eyes? Do you know of any salt that you should inhale? You believe table salt is as effective as Calcium chloride, so maybe you could try putting table salt into your eyes and inhaling it? Or how about ingesting spoonfuls of it? It’s non-toxic right! Or how about flour? Sugar? Cinnamon? If these common comestibles aren’s supposed to come into contact with your eyes and you cant inhale them? How can they be considered safe?


Lyn July 14, 2016 at 3:55 pm

“But these crystals aren’t meant to give off any gases or fumes, so why can’t you inhale them?”

This product is calcium chloride which can cause burns in the mouth and esophagus, as well as effects like stomach pain, vomiting, low blood pressure, weakness, irregular heartbeat, mental disturbances and even coma if swallowed. As a result the reaction caused by absorption is safe BUT actually inhaling or swallowing the crystals or crystal particles is anything but.

Please edit your review before someone gets it in their head to think your ridiculous statement makes sense.


Richard Hensel August 24, 2016 at 6:31 pm

Try Rita’s Sphere. It actually kills and prevents mold and mildew. Just saying.


Cindy October 3, 2016 at 11:19 pm

I googled Rita’s Sphere and got nothing that relates to this thread. Is this a product found in the US? If so, please advise where.


shubert September 6, 2016 at 7:19 am

This is a DEhumidifier – NOT a humidifier
I collect those dessicants in food and vitamin containers
kitty litter works too, silica gel
Clay works
Ice melt pellets are cheaper
Rock salt is even cheaper


terry suarez September 10, 2016 at 3:04 am

I have a 2010 honda civic sedan. the truck for some reason even when closed accumulates water in the compartment. even though honda has a rubber sleeve on top, water still gets underneath and on the carpet area. Worst part about it, being in Florida, during hot days, the inside of the car is full of humidity inside on the windows. Can I put damprid inside my car to remove the water and therefore, eliminate the humidity inside the car?

HandyMan October 25, 2016 at 2:47 pm

I found a similar product, probably same chemicals that they use here, that i have already tried and works. Placed 2 of this in my damp basement (after heavy rain) and the products absorb the moisture in the air and improve the humidity.. i use a cheap temp and humidity meter.. i think its similar to what i found below online..


Hello July 1, 2018 at 11:02 am

I buy those exact items at Dollar Tree for $1 each…hope you have one close to you..


Sincerely Sonia September 14, 2018 at 11:22 pm

Go to walmart. They have the namebrand 2 packa for $4.97. When I pulled up your link on amazon, it said $11.97!


Elaine Johnson March 13, 2017 at 1:25 am

I am a Winter Texan, I am here for 3 months in the winter, the summmers are very humid. What do you suggest I put in the closets while I am away for the other 9 months.


Deana April 5, 2017 at 8:53 pm

The hanging bags work best for bigger rooms. I use 3 hanging and 3 refillable buckets in our church basement, 1 bucket in each classroom 1 hanging in the very long, very damp hallway, and one in the kitchen and large dining area. They keep the mildew smell completely gone and replaces it with a nice fresh fragrance. Been using them for 3 yrs. now, and everyone is always complimenting on how much better it smells after 12 yrs. of mildew odor. They only last 5 weeks tho for us, due to the high moisture from solid concrete walls and no covering. We have several members that have Asthma and severe allergy reactions to the mildew so, it was hard for them to stay in the basement very long, now there is no problem the Damprid works great, they now can stay down there for hours without any symptoms of getting sick. We also had to scrub down the concrete walls every summer after the spring rains to remove the mildew from them. Not anymore. Well worth the investment!!!!!


LJ May 14, 2017 at 3:47 pm

Just but a cheap dehumidifier. It will remove ten times the moisture from the air. A dehumidifier only needs to be emptied every three to four days and replaced every ten years or so.


Mark July 26, 2017 at 4:22 pm

I put a couple buckets on my backyard deck and they didn’t do a thing to stop the rain. Had to cancel my BBQ get together.


Debra August 23, 2017 at 5:51 am

I think they’re amazing! I hung 3 bags a little over a weeks ago, 2 in closets and one in the laundry room, due to a stuffy and stagnant smell. All 3 bags are already 1/4 full of fluid and the areas all smell so much better. Wish I had known about this product when I lived in Texas…would have saved a whole lot of clothes from mildew!


gibson October 2, 2017 at 4:51 pm

Have the hanging version of this. Put in my small bathroom closet. Today went to get something out of a storage box in there (it’s one of the gasket type boxes thank goodness). The bottom of the bag where the liquid collects leaked! Is this liquid dangerous? I have a cat, a very curious cat. I’ve cleaned the floor (and found clear ‘crystals’ of what the liquid turned into), gotten everything up possible. Noted that while cleaning it left a kind of film(?) on my hands, immediately washed them. I’m just using white vinegar and water to clean the outside of the boxes and floor and letting that air dry. If my cat got into the leaked water which is possible, is he in any danger? Thank you.


Jo October 22, 2017 at 12:49 pm

Ummm I think you mean electric DE-humidifier, as you are trying to get rid of the moisture in the air


Linda January 15, 2018 at 5:38 am

I had a bit of a water leak which went in underneath the bathtub and into a wall cavity, which then leaked through onto the carpet. It absolutely stank and I bought one of those damp rid things..Absolutely brilliant! The carpet is dry, the room doesn’t smell revolting any more,but the bucket has got like a ice cream constancy to the crystals. Is that usual or is it time for a replacement?


mary August 28, 2018 at 12:34 am

How did You get into the Wall – under the bathtub? I have kind of a similar problem myself…I can see thru the linen closet (after breaking the wall down) that the floorboards right in front of the tub are water logged a bit – did you just stick the bucket right there? I dont know, I have multiple issues Its driving me NUTS!


A User January 22, 2018 at 6:58 am

“While some people find the product works for what it is, others have noted that mildew and mold can grow in humidity of fifty five per cent, but these smart crystals only start working at sixty per cent. That leaves a five per cent chance that you will still struggle with mold even if you use these crystals.”

A ‘five per cent chance”? This is not how percentages work.


Another User January 22, 2018 at 7:00 am

‘five per cent chance”

This is not how quote marks work.


Ellen May 20, 2018 at 5:31 pm

Since private and independent contractors have cheaper service
rate, you should expect ann unhealthy installation of carpets.

A hanging damp rid has leaked on slacks. How do I get rid of the bad stains. Oxy clean & Tide detergent did not help.

I live in S.W. Florida. There is no way this product removes enough moisture to reduce the chance of mold in a closet or room. Check out your A/C drain and see the water dripping out. GALLONS! If your A/C is working properly your indoor humidity should be less than 55% and you will not need a product like this.

I’m not convinced. I live in humid Hawaii. The air is constantly moist. Yes, the crystals collect water, but the air is so humid that I feel Mother Nature is constantly winning – no matter how many of these things I install.

It’s a dehumidifier, not a humidifier. It’s tough to take your review seriously if you don’t distinguish a difference.

We used open bags of charcoal in our closets when leaving for several months when I was young to keep down mold and mildew; that was before Damprid. My experience with Damprid was in a basement that had been very wet all the time before I bought the house; we had to put in outside pipes, the kind with holes in them, all around the outside of the basement, then inside the basement put several Damprid small buckets between the 2 x 4 posts on the walls. It worked great, we were able to carpet the basement and no more wet basement problems. I think after the Damprid when we wanted to enclose the walls we used kitty litter and left it in place, walled them in and put our toolroom down there.

Why not just use baking soda, is stuff suppose to be so much better?

We had an oily substance on the floor of the closet and couldn’t figure out where in the world it was coming from. Finally, one day I discovered it was from the Damprid packet that my husband had been placing in the closet for years. Unfortunately, he didn’t place the packets in a bucket as directed and it leaked into the floor and became a stain on the ceiling below. What a huge mistake it was to use the packet without a basin of some sort to catch what was supposed to be “water”. This oily substance is disgusting and now we need to repair our drywall ceiling :/ Very frustrating. Baking soda is what we will be using in the future!

I use this in my RV (which is my actual home). I think damprid works very well. The people I bought my RV are the ones that told me about this product. I have a bag in the closet and a bucket in the restroom. When the AC fan quick I placed one in the living area. I like this product.

This stuff works !!! But best to start before you have the mold or extreme damp problem. We travel to humid climates every winter, so knowing that installed these in every corner, closet , cupboard, then check them regularly and replace immediately as needed . Consequently , we have no problems
