The SereneLife 2-in-1 Dehumidifier pairs a thermoelectric room dehumidifier with a removable desiccant cylinder for closets and drawers. The main unit holds the room between 45% and 55% humidity. For more models, see our Compact Thermoelectric Dehumidifiers page.
Our Verdict
It is a clever choice when you need to protect both a room and a closet, and its automatic humidity control is rare at this price.
At 50dB it is louder than most Peltier units, and SereneLife does not list a daily capacity.

Design
The main unit has an 85 oz tank with a full indicator and auto shut-off, and measures 9 x 6 x 13 inches.
The cylinder lifts out to absorb moisture in a closet or drawer, then recharges on the drying base in two to three hours.
Controls
Smart humidity detection keeps the room between 45% and 55%. Timers run for 6, 12 or 24 hours, and a sleep mode and two fan speeds are included.
A defrost function protects the unit in cooler conditions.
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 Eva-Dry EDV-2400, the SereneLife costs less and adds the cylinder, while the Eva-Dry is quieter and lets you pick the target.
Against basic minis, it is louder but handles a closet and a room at once.
