Extended moisture control for small, enclosed spaces
The Eva-Dry E-333 is a compact, renewable mini dehumidifier designed for spaces that benefit from longer-lasting moisture absorption. With a higher capacity than smaller models and the same silent, cordless operation, it’s an easy, dependable solution for everyday environments.
Why it fits your space
The E-333 is well suited for enclosed or lightly ventilated areas where moisture can build gradually over time.
Common uses include:
• Closets and wardrobes
• Cabinets and storage areas
• Safes and storage boxes
• RVs, travel trailers, and boats
• Utility rooms and seasonal storage
Its slightly larger capacity allows it to remain effective longer between recharges, making it ideal for spaces that are accessed less frequently.
How it works
The E-333 uses renewable silica gel to absorb moisture directly from the air. As moisture is collected, the beads change color, providing a clear visual cue when it’s time to recharge.
Recharging is simple:
1. Plug the unit into a standard outlet
2. Allow it to recharge until the beads return to their original color
3. Unplug and return it to use
No refills. No disposable components. Just repeat as needed.
Designed for quiet reliability
• Cordless operation during use
• Renewable silica gel—no ongoing replacement costs
• Silent performance with no moving parts
• Compact design with extended moisture capacity
The E-333 is designed to work quietly in the background, with minimal attention required.
Specifications
• Moisture absorption capacity: up to 13 oz
• Coverage area: up to 333 cubic feet
• Recharge time: approximately 10–12 hours
• Indicator: color-changing moisture beads
• Power: 110–120V (recharge only)
Consistent moisture control, made simple
The Eva-Dry E-333 offers a practical balance of size and capacity, making it a dependable choice for maintaining comfortable humidity levels in smaller spaces over longer periods.

I am very happy with it, works great and is exactly as described. Definitely would purchase again.
I was not expecting to have to plug this in to recharge it. Also the one I ordered had no directions. I had to scan the QR code in order to figure out what to do. Overall, I feel a little less moisture in the full bathroom, but I honestly thought it was going to work better.. best being for your back probably not.
