What every best Dehumidifiers has:
- Large capacity.
- Ample collection container.
- Multiple fan speeds.
Small but effective for small spaces. Owners posting to Amazon.com say the Eva-Dry Renewable E-333 Wireless Mini Dehumidifier might be small, but it works like a champ. This mini dehumidifier will absorb about 6 ounces of moisture before it's at capacity. That's sufficient for a small bathroom or a closet or cabinet. Some owners use them in spaces as small as drawers. Another popular use is to prevent moisture damage to firearms stored in a gun safe (and we recommend the top gun safes in our separate report on home safes). After it's full, the Eva-Dry must be plugged in to an electrical outlet in a well-ventilated area to fully discharge the collected moisture and recharge itself. Reviewers at Amazon estimate that it takes between 10 and 12 hours to complete this process.
Extremely simple. With no batteries and no electricity to worry about, the Eva-Dry E-333 couldn't be easier to use. The interior of the unit contains crystals that are orange when dry and turn green when wet. When all visible crystals turn green, as seen through the unit's indicator window, it's time to plug the unit in to release the moisture. (That color combination was adopted in 2016 for better visibility than the previous crystals, which were blue when dry and pink when wet.) The E-333 is only suitable for very small spaces -- up to 333 cubic feet. Moisture is vented to the air when released, so keep that in mind when picking a space to recharge the unit -- outdoors or a next to an open window in large room works best.
Quiet as a mouse. The Eva Dry dehumidifier is, essentially, completely silent during use because it doesn't require batteries or electricity to operate a fan. Even when plugged in to release the collected moisture, the unit doesn't emit any noise.
Solid track record. The Eva-Dry E-333 dehumidifier needs no batteries or electricity to operate and has no moving parts to break down. User reviews, some of which indicate years of use, are positive for the most part. The warranty is for 5 years.
