The Star Brite No Damp Dehumidifier (85412) is a chemical moisture absorber designed to combat excess humidity in enclosed spaces aboard boats, RVs, seasonal homes, and storage areas. Using specially formulated calcium chloride pellets, it continuously pulls airborne moisture out of the air and deposits it safely as a liquid solution in the sealed outer container — no electricity or maintenance required.
When placed in a confined area, No Damp dries the surrounding air to a level where mildew and musty odors cannot take hold, helping to protect stored goods, upholstery, electronics, and other valuables from moisture damage. The 12 oz. bucket treats up to 900 cubic feet, making it ideal for smaller enclosed spaces.
Key Features:
- Calcium chloride pellets absorb more than their own weight in airborne moisture
- Three-piece design: outer container, inner basket, and perforated top for maximum airflow through the pellets
- Inner basket design increases absorption efficiency and extends the life of the absorbent
- Dries enclosed air to a level where mildew and odors cannot grow
- Resulting liquid solution is non-toxic and can be safely disposed of down the drain
- Refillable — add new pellets directly on top of remaining chemical when absorption diminishes
- No power source required — completely passive operation
- 12 oz. capacity treats spaces up to 900 cubic feet
Ideal for boat cabins, heads, closets, safes, camper interiors, basements, vacation homes, and other small enclosed areas. Protection lasts for weeks depending on humidity levels, ambient temperature, and the size of the space being treated. Check weekly and pour off collected liquid as needed.
