The Pro Breeze 52 oz Mini Dehumidifier is Pro Breeze’s larger thermoelectric dehumidifier. It removes up to 18 oz of water a day into a 52 oz tank and covers about 250 sq ft, quietly and without a compressor. For more models, see our Compact Thermoelectric Dehumidifiers page.
Our Verdict
This is our top pick among mini dehumidifiers for a damp bedroom, bathroom or office. The tank is big enough to run for days, the Peltier module is quiet, and it weighs only 4.5 pounds.
It has no humidistat, timer or drain hose, and like all Peltier units it slows down in cool rooms.

Key Specifications
| Feature | Specification |
|---|---|
| Brand | Pro Breeze |
| Model | 52 oz Mini |
| Moisture Removal | Up to 18 oz per day |
| Tank | 52 oz with auto shut-off |
| Coverage | Up to 250 sq ft |

| Weight | 4.5 pounds |
| Dimensions | 6.6 x 9 x 12.7 inches |
Design
The 52 oz tank is about three times the size of the 16 oz Pro Breeze, so it needs emptying far less often. When it is full, the unit switches off and an LED lights up.
At 6.6 x 9 x 12.7 inches and 4.5 pounds, it is easy to carry between rooms or take to a camper.
Controls
Controls are minimal: plug it in and switch it on. There are no modes, timers or humidity settings.
That simplicity suits closets and spare rooms, but you cannot tell it to stop at a set humidity.
Placement Tips
Set the dehumidifier on a level surface in the dampest part of the space, with a few inches of clearance around the intake and outlet. Close doors and windows while it runs so it is drying the room, not the outdoors.
Keep it in a room that stays above about 59 degrees F. Thermoelectric plates lose most of their effect in a cold garage or basement.
Running Costs and Care
Empty and rinse the tank every few days so it does not grow mold, and wipe dust from the intake grille. A clean unit removes more water.
Running costs are low: thermoelectric units draw roughly the power of a light bulb, so leaving one on around the clock costs little.
How It Compares
Against the 16 oz Pro Breeze, this model removes twice as much water a day and holds more than three times as much.
Against dual-core units such as the Litever Dual Core, the Pro Breeze removes less water but is a simpler, proven design.
