SafeNDry XL Gun Safe Dehumidifier - Portable Moisture Absorber, Prevents Corrosion, 450g Reusable Indicating Silica Gel Desiccant Canister for 60 Cubic Feet

Why we love it
  • Cost-effective moisture control solution.
  • Reusable, saving you money long-term.
  • Protects valuable items from damage.
Main Highlights
  • What's Inside: one pouch containing 450 grams of color indicating silica gel beads in plastic display container. It effectively protects up to 60 cubic feet of space from corrosion and moisture, making it ideal for gun safes, ammo storage, stamp collections, family photos, books and documents storage, ammunition storage, and other enclosed environments prone to moisture buildup.
  • Cost-efficient and reusable: when the beads turn pink it is time to reactivate them. To reactivate/recharge its moisture-absorbing capabilities, simply remove the pouch from the canister and place in an oven at 240 degrees Fahrenheit for 3 hours or until the beads turn blue again. This process can be repeated multiple times, offering a reliable and cost-effective solution for moisture control​ inside closed spaces.
  • Spill proof: contains no liquids. The inner pouch keeps the silica gel beads contained while the plastic canister increases airflow inside any sealed area.
  • Protect your valuables: Ensure your gun safe, collectibles, ammo, and other precious items remain in pristine condition with the SafeNDry XL Gun Safe Dehumidifier. This non-electric, reusable silica gel dehumidifier is perfect for those who value simplicity and efficiency. Protect your valuables by removing excess moisture from containers and safes.

Why we love it
  • Safe for all environments.
  • Highly efficient moisture absorption.
  • Renewable and eco-friendly design.
Main Highlights
  • Safe and Non-Toxic: Featuring non-toxic silica gel beads, these dehumidifier sticks efficiently absorb moisture. A top window allows easy monitoring of their status for timely updates. The sticks can be placed anywhere independently, requiring the heating base only for periodic regeneration.

The base includes a built-in heating function; when the silica gel beads change from orange to dark green, simply place the sticks on the PTC heating base for approximately two hours to recharge (automatic shut-off prevents overheating). This process is convenient and economical, allowing for eco-friendly regeneration at home.
  • Versatile 4-Pack Design: Tailored for diverse household needs, this multi-pack offers excellent versatility and convenience.

Why we love it
  • Efficient 360° moisture absorption.
  • Renewable and eco-friendly design.
  • Safe, non-toxic silica gel.
Main Highlights
  • 【360° Circular】 The cylinder design of the cordless dehumidifier increases the moisture-absorbing area and the 360° circular air inlet makes moisture absorption more efficient.

When the silica beads in the small dehumidifier change from orange to dark green, just place it on the PTC heating base for about 2H to reuse (automatically shut down to prevent overcharging). NOTE: After 2H, if the dehumidifier stick continues to be placed on the heating base, it will not be renewed all the time. If you want to continue renewing, please pick it up and then put it back on the heating base.
  • 【Safe Dehumidifier】 Non-toxic, safe silica gel beads efficiently absorb damp and moisture from the air. Through the top window of the mini dehumidifier, the use status can be observed at any time, which is convenient for reminding to renew the dehumidifiers in time.
  • 【Mini Portable】 This portable dehumidifier removes up to 4oz/100ml of moisture (86°F, 80% RH) and dehumidifies up to 54 sq. ft. Only the heating base is wired. The dehumidification stick can directly dehumidify, and does not need to be used on the heating base all the time. Mini size design is perfect for small space, bathrooms, closets, wardrobes, cabinets, gun safes, bookcase, gym bags, cars, RV, boat etc.
  • 【Eco-Friendly】 No batteries or electricity required for this dehumidifier to dehumidify, only 50W low energy consumption for the heating base (American standard plug, AC100-120V 50/60Hz). No worries about tilting of the water tank or overflowing. If you have any questions, please feel free to contact us. Afloia always offer thoughtful plan to ensure your perfect experience.

Why we love it
  • Crisp steel triggers enhance safety.
  • Active airflow prevents moisture buildup.
  • Effortless installation and maintenance-free.
Main Highlights
  • Save Your Guns - No sticky triggers, just crisp steel, smooth mechanisms. Our gun safe dehumidifier actively circulates warm air inside your safe, raising the internal temperature just enough to disrupt moisture buildup before it starts, which repels rust and preserves both function and value.
  • Dual-Action Defense: Heat + Active Airflow = Total Moisture Control- Most dehumidifiers just sit there — ours fights back. While traditional heating rods rely solely on passive convection, our gun safe dryer combines precision heating with an integrated silent fan to force moist air out through door gaps and seals. Shielding guns, ammo, documents, and heirlooms from ruin.
  • Set It & Forget It: True “Maintenance-Free” Protection- There’s no refills, no moving parts to replace. Simply plug it into any standard outlet, route the cord through an existing or drilled hole, and switch it on. From that moment forward, it runs silently 24/7. Perfect for busy owners, collectors.
  • Effortless Installation in Minutes - Feed the power cord through a pre-drilled hole (or make one with a hand drill), plug it in, and position the unit on the floor or shelf. Its compact profile fits almost any safe layout without blocking access or shelves. And because it draws less power than a bulb, you’ll never worry about energy costs — making it cheaper and far more effective than disposable silica packs.
  • Compact for Gun Safes (3.5–11 cu ft) - At only D*H:3.34*4.13 inches, it tucks neatly into small pistol safes or larger vaults alike.
