The Absodry Duo Family Refills are designed to fit Absodry Duo Family Moisture Absorbers. These premium refill bags are also suitable for use with other moisture absorbers with a capacity that allows 600g of crystals to be added. Each Refill pack contains 2x 600g refill bags of moisture-absorbing crystals. Each refill bag is capable of lasting up to 3 months, providing a total potential lifespan of 6 months in each refill pack depending on humidity levels and location. The ultra absorbent calcium chloride crystals inside the bag pull excess moisture in the surrounding air which is then converted into water, reducing humidity in the surrounding area.
