DampFree Refill Crystals give you the freedom to tackle damp in the trickiest corners of your home. Designed for use in any reusable moisture absorber unit or spill-proof DIY container—like small pails, tubs, or buckets with a breathable lid—these powerful calcium chloride crystals draw in excess moisture from the air and trap it as liquid. They’re perfect for high-humidity areas where mould, mildew, condensation, and musty odours tend to thrive.

The generous 3.4kg size is ideal for larger or more exposed areas that need long-lasting moisture control. Think garages, sheds, garden rooms, home gyms or under-the-house storage zones—places where sweat, steam, and poor airflow can quickly lead to a damp environment. By lowering humidity levels, they also help protect stored tools, gym equipment, and metal hardware from rust and corrosion. They’re also a great option for kitchens, laundries, or caravans and boats when stored for long periods.

To use, fill your container with up to 300g of Refill Crystals, place it in position, and let the crystals get to work. The resealable bottle features a safety lock cap to prevent unwanted activation of crystals between uses. No power, no noise, no fuss—just a reliable, heavy-duty moisture solution that fits the spaces standard units can’t.
