DampRid® Hi-Capacity Moisture Absorber Tubs are sold in packs of 2. MEETS ALLOWABLE SPECIFICATIONS - Each DamRid tub is a 2lb bucket with a 4lb capacity. DampRid is made up of calcium chloride crystals. These natural crystals effectively control musty odors caused by excess moisture for up to 60 day sin areas up to 1,000 sq-ft, or up to 6 months in a 250 sq-ft area. 

Easy to use, just remove the lid to activate the crystals, and place on a flat surface. The Moisture-Lock(TM) technology and sealed safety cover prevent spills and keep children & pets out. As the DampRid absorbs moisture from the air, the Calcium Chloride crystals harden and disable. A red arrow on the tub will indicate when the crystals are completely dissolved and it's time for a new DampRid.
