While DampRid will reduce moisture in your home and thereby help to prevent mold, we think a good dehumidifier does an even better job. DampRid only removes moisture from the air immediately around the container, so for a large room, you would likely need multiple containers.

Does DampRid get rid of moisture?

DampRid essentially works to remove excess humidity from small spaces. It absorbs moisture so it isn’t just hanging out wreaking havoc and creating an environment for mold to grow. DampRid generally comes in either a bag or a bucket. There are crystals that, when exposed to air, absorb the excess moisture.

How long does DampRid take to work?

Mold only takes about 24-48 hours to begin to grow. Ironically, the very item used to prevent mold or mildew can quickly become the main culprit if you are not careful. Remember, DampRids are a salt-based solution so it is important to saturate and dilute the solution to prevent stains.

How long does DampRid last?

DampRid crystals absorb excess moisture to create and maintain the optimal humidity level wherever moisture is a problem. Each dehumidifying bag can last up to 60 days depending on the level of humidity and temperature. When the bag is finished, simply discard and replace.

Where is the best place to put DampRid?

Place DampRid in all bathrooms, basements, closets and laundry rooms to prevent excess moisture and moisture damage. If you have outside irrigation turn off the supply and flush out the water.

What is better than DampRid?

Although, on any given day dehumidifiers are better in function and capacity in comparison to DampRid. This is because for any dehumidifier to work you require air flow, and that device can create it.

Why does DampRid turn black?

How do you know when DampRid is full?

It may take a few days before liquid begins to drip. Accumulated moisture will drip into the bottom chamber, and about half to three-quarters of the crystals will dissolve. All of the DampRid crystals will dissolve and the bottom chamber will be full of liquid.

Will DampRid help with mold?

(Moldoff.org) DampRid™ Mildew and Mold Blocker is readily available at hardware stores and home centers and works great on both hard and porous surfaces and will keep mildew and mold from coming back once cleaned (Damprid.com). For areas that will not or cannot be cleaned, then testing is a necessary step.

What are the crystals in DampRid?

The white crystals are calcium chloride, which is a non-toxic inorganic salt product. As with all salt-based products as they begin to absorb moisture they harden. The DampRid is acting like a moisture magnet pulling the moisture from the air and trapping it in the lower chamber of the product.

Should I place DampRid high or low?

We placed the tub on the floor and used it in conjunction with the DampRid hanging moisture absorbing products. The tub absorbed a lot of moisture when placed on the floor so that’s probably where I’d put it. You could try it up higher but be careful when you move it once it begins to fill up with liquid.

Do you use DampRid in the winter?

I use Damp Rid during the winter, yes.

Does DampRid smell?

DampRid can smell bad due to the calcium chloride. This is non-toxic, but it can lead to an unwanted odor and some irritation once inhaled.
