Great For Humid Climates To Prevent Rust, Rot & Mildew
Compact, renewable unit removes moisture from closets, cabinets, gun safes, and enclosed areas to protect your guns and valuables from rust, corrosion, rot, and mildew. Odorless and non-toxic Water Glass Technology crystals absorb moisture for up to 60 days before regeneration is required. Self-contained—does not require power to operate. Just plug it in to a 110v outlet for 8 to 10 hours to completely regenerate. The indicator window will turn blue when the unit is fully charged and ready to absorb moisture; pink indicates it needs regeneration.
