Key Features
RECHARGEABLE GUN SAFE MOISTURE ABSORBERS: This renewable silica gel dehumidifier is perfect for gun safes, closets, cabinets, boat cabins, and small enclosed spaces up to 500 cubic feet per unit. Includes five twist-lock closet hangers. Coverage is per unit and does not combine — five units protect five separate 500 cu ft spaces, not one 2,500 cu ft area. Open rooms and ventilated spaces need a powered dehumidifier. Operates cordlessly — no batteries, no power cord. Protects firearms, valuables, and belongings from rust and corrosion.
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. Non-toxic silica gel absorbs moisture without chemicals or calcium chloride. One purchase, a decade of protection, backed by a 5-year limited manufacturer's warranty.
WIRELESS DEHUMIDIFIER FOR BATHROOM: Keep your bathroom free from excess moisture with this compact, wireless dehumidifier. It helps prevent moisture issues while maintaining a fresh and dry space—no batteries or cords needed. Silent operation.
CORDLESS DURING USE — PLUG-IN TO RENEW: No batteries ever. During the dehumidification cycle the unit operates completely cord-free. 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 18 hours — overcharging permanently damages the indicator beads and they may no longer change color reliably. Set a timer.
RENEWAL — WHAT TO EXPECT: The unit becomes hot during the 16–18 hour renewal cycle — this is normal for silica gel regeneration. Allow it to cool fully before handling. Place on a hard, heat-resistant surface in a well-ventilated area, away from children and pets. If beads remain green after a full cycle, unplug, cool to room temperature, shake gently, and run a second cycle.
5-PACK VALUE — PROTECT MULTIPLE SPACES SIMULTANEOUSLY: Each unit operates independently, covering up to 500 cubic feet. Use across five different spaces — gun safes, closets, bathrooms, boat cabins, RVs, cars, and more — or rotate units through renewal cycles so you always have a dry unit ready to deploy. In cold or dry climates, the dehumidification cycle may take longer as less moisture is available in the air. UL Listed. CE Certified.
