The Eva-Dry E-500 Renewable Mini Dehumidifier uses a renewable silica gel technology that works without batteries or power. It can be placed in any area up to 500 cubic feet and will silently absorb moisture. No messy spills to clean or refills to buy…ever! We use these in our travel trailer and they work perfectly during the camping season and while in winter storage!
As it absorbs the humidity there is an indicator window that contains crystals that will change from orange to green. Once the crystals have changed to green, it is ready to be plugged in for 12 to 14 hours in a well-ventilated area. After 12 to 14 hours the crystals will have changed back to orange and it is ready to be used again. The process can be repeated for up to 10 years!
Even at full capacity, the E-500 will never leak or spill a single drop of liquid. It captures moisture vapor from the air and keeps it contained within the beads until the unit is ready to renew. Since the E-500 is renewable, it will not require any expensive refills. The E-500 has a lifespan of 10 years and is covered by a 5 year warranty.
