About this item

• RECHARGEABLE GUN SAFE MOISTURE ABSORBERS: This renewable silica gel dehumidifier is perfect for gun safes, closets, boat cabins, RVs, and small enclosed spaces up to 500 cubic feet per unit. Operates cordlessly during use — no batteries, no power cord. When the indicator turns green, plug into a power strip for 16–18 hours to renew, then redeploy. Protects firearms, valuables, and belongings from rust, corrosion, and moisture damage.
• LESS WASTE | LASTS UP TO 10 YEARS: The E-500 is a renewable dehumidifier that lasts up to 10 years with no refill costs ever — saving $10–20 per year compared to disposable moisture absorbers. Eco-friendly, non-toxic silica gel absorbs moisture without chemicals or calcium chloride. One purchase, a decade of protection.
• CORDLESS DURING USE — PLUG-IN TO RENEW: Operates silently without batteries or cords while dehumidifying. When the color indicator turns from orange to green, plug into a power strip — do not plug directly into a wall outlet, as the unit's weight can cause it to fall. Place on a hard, heat-resistant surface in a well-ventilated area for 16–18 hours. Do not exceed the recommended renewal time — over-charging can permanently discolor the indicator beads. Set a timer.
• RENEWAL — WHAT TO EXPECT: The unit will become warm to hot during the renewal cycle — this is normal. In cold or dry climates, renewal cycles may take longer as less moisture is available in the air. If beads remain green after a full cycle, unplug, cool to room temperature, shake gently, and run a second renewal cycle. Contact Eva-Dry support if the issue persists.
• 2-PACK VALUE — COVER TWO SPACES SIMULTANEOUSLY: Each unit operates independently, covering up to 500 cubic feet. Use one in your gun safe and one in a closet, or place them in any two small enclosed spaces that need simultaneous protection. Includes two twist-lock closet hangers — no shelf space required. Color-change indicator (orange = dry and ready, green = full and needs renewal) tells you exactly when to recharge each unit.
