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.

That being said, the DampRid website describes it as a nontoxic inorganic mineral salt called Calcium Chloride which is very clever little crystals that only get going when the humidity goes above sixty per cent. They lay dormant when the levels are below sixty per cent and will not harm plants, children, or animals.

The Claim
From evaluating the feedback on DampRid it really does seem to make a difference. The crystals are completely odorless and don’t release any fumes or gasses. These crystals absorb the excess moisture turning the crystals into a solid mass which then release the excess water into the bottom of the container. Due to this you must take extra care when emptying, you don’t want dirty salty water all over your carpets, having to repeat the process.

The amount of water released and how long it takes to release water depends on the moisture content in the air.

The Hype
The exciting thing about this product is that it doesn’t release fumes or gasses and removes excess water from the air, an ideal choice for anyone suffering with asthma or allergies.

It doesn’t require electricity unlike the expensive electrical humidifiers and is a bucket of crystals, you take the lid off and pop it where you want. It is suggested that you put it high up out of reach of animals or children. The DampRid site states that these crystals are nontoxic and if a child or pets puts them in their mouth, they will spit them out quickly due to the taste.

These little buckets of moisture absorber are affordable, but are they cost effective? You will need to keep a close eye on your DampRid container to ensure that it hasn’t collected too much water and while they are affordable, the overall long term cost will depend on how much moisture is in the air.

When emptying you need to take special care and only pour down the toilet while flushing and you thought it was nontoxic and safe. It suggests you do not put it down the sink and if spilled, wipe immediately with a damp cloth.

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 big concern is that DampRid clearly states that these crystals are non-toxic and pets and children won’t swallow them and just spit them out due to their fowl taste.

On reading the instruction leaflet you will get a different story with warnings that 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?

Final Review of DampRid

After thoroughly researching DampRid and reviewing many consumer experiences on this non-electric humidifier, I believe it really does work to some degree. I do believe that the amount of moisture in the air will determine whether it is in fact a cost effective choice for your home.

You will need to buy one for each damp room where you are trying to avoid mildew or mold and while they are affordably priced, it depends on how many you need to purchase and how often you need to replace them.

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

As this product clearly does help with unwanted mildew and mold, it is recommended for homes that do not have children or pets. Children and pets always manage to get into things they shouldn’t and the health hazards seems a little vague when it comes to DampRid.

This humidifier is definitely convenient and cost effective in a majority of homes and if you’re looking for quick and easy, this may be the right choice for you.

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 :-)

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.

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.

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

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

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 :-(

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!


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.

Don’t you mean “dehumidifier”?

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.

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!)

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?
