A capable small-room dehumidifier if 230 square feet or less covers your space and quiet overnight operation matters more than raw water removal.

Overview
A small semiconductor dehumidifier for rooms up to 230 square feet, holding 58 oz (1657 ml) of water before the tank needs emptying. Three modes, 10 night-light colors and five timer settings cover bedrooms, bathrooms and closets.
This is a budget bedroom-size unit rather than a whole-basement machine, so the 230 sq ft rating matters more than the tank size when deciding if it fits your space. Sleep mode is rated under 40 dB, which is the detail that actually determines whether it can run overnight next to a bed. Auto shut off triggers on a full tank or if the unit tips, a basic but useful safeguard for a device often left running unattended.
- 58 oz (1657 ml) water tank
- Covers up to 230 square feet
- 3 modes, sleep mode under 40 dB
- 10-color night light, 5 timers
Who it's for
Fits anyone drying out a single bedroom, bathroom or closet rather than a whole floor. Not a match for a basement or open living area near or above 230 square feet, where a larger compressor unit will keep up better.
Pros and cons
- 58 oz tank needs less frequent emptying
- Under 40 dB in sleep mode
- Five timer options from 24 to 96 hours
- Tip and full-tank shutoff protection
- Rated to only 230 square feet
- No humidity readout mentioned
- Night light may not suit everyone
Performance notes
The unit uses semiconductor (thermoelectric) cooling rather than a compressor, which is why it can run quietly but also why its capacity is aimed at small rooms rather than large or damp spaces. Defrost technology clears frost from the semiconductor automatically so performance doesn't drop off in cooler rooms. Sleep, normal and performance modes trade noise for moisture removal speed, and the auto shut off responds to a full or dislodged tank rather than to a set humidity target.
