How DampRid® Works

When DampRid's white pellets are exposed to the air, they absorb excess moisture and dissolve into a brine (salt solution). They won't dry the air to a level that damages plants, animals or clothing. The formula is non-toxic, septic safe and friendly to the environment. It's safe for home, family and pets and is easy to dispose of after use.

DampRid® Moisture Absorbers work in three phases:

Phase 1:
Excess moisture is absorbed into the white calcium chloride crystals. The white crystals begin to harden and form a solid mass. They have not yet dissolved. You may see liquid dripping into the bottom chamber of the product at this stage.



Phase 2:
Excess moisture will most likely be dripping into the bottom of the product. Approximately 1/2 to 3/4 of the white crystals will have dissolved.




Phase 3:
All of the white crystals will have dissolved and the bottom of the product will be full of liquid. You will see a small line of colored freshener beads in the top chamber of our DampRid fragrance products.



Discard the DampRid® product and replace with a new one. For refillable products, empty the collected liquid into the sink (with running water) or toilet and refill.

The timeframe listed for each product should only be used as a guideline. The product may last a shorter or longer period of time depending on changes in temperature and humidity.

DampRid® products come in a variety of sizes and types — one will be just right for you.


DampRid® only absorbs excess moisture from the air — if placed in an area where humidity is not a problem, the crystals will not begin to harden and dissolve. The DampRid crystals remain viable and continue to work, but only as needed.

DampRid® crystals will initially harden as part of the natural moisture absorption process. Some consumers incorrectly assume the product is defective when they see the hardened crystals.

If DampRid® turns to liquid form in a matter of days, this signals significant humidity and may indicate a serious moisture problem that should be looked into by a professional contractor or inspector.

DampRid® crystals may turn color — often brownish, orange, reddish, pinkish — from trace amounts of minerals in them. This discoloration does not affect performance, and can be rinsed off with water or left until the crystals have dissolved away entirely.
