The DRI-IT Twin Pack Moisture Absorber contains Two Pouches, which are pre-measured, completely self-contained and ready to use. Moisture is absorbed through a breathable membrane that looks like paper. One side has a peel-and-stick backing that can be stuck to non-delicate surfaces (or just place anywhere without using the sticky backing). When the environmentally safe Calcium Chloride beads turn into gel, simply toss it into your household trash for Eco-Safe disposal. Each Pouch of The DRI-IT Twin Pack Moisture Absorber will dehumidify an enclosed area up to approximately 50 cubic feet. How long it will last depends on the relative humidity of the enclosed space. Every DRI-IT Twin Pack includes a distinctive HUMIDITY INDICATOR CARD as part of our UNIQUE HUMIDITY SOLVING SYSTEM. It will help to verify if you have enough DRI-IT product for the size of your space and to indicate when you need to add a new pouch to maintain humidity control.
