Vremi 22-Pint DehumidifierApartments, single damp rooms, and anyone who wants a smaller lighter unit.
For closets, bathrooms, and RVs, the Pro Breeze mini is the right tool: silent thermoelectric operation in a tiny footprint. Understand its limits: it extracts ounces per day, not pints. Anything bigger than a small room needs the Vremi 22-pint instead.

Best mini overall
Pro Breeze Electric Mini Dehumidifier
Whisper-quiet thermoelectric for closets and RVs.
Strengths
- Thermoelectric (Peltier) design runs whisper-quiet with no compressor
- Compact and light enough for a closet shelf or RV counter
- 16 oz tank with auto shutoff; simple and cheap to run
Limitations
- Extracts roughly 9 oz per day, a fraction of even the 22-pint unit
- Only meaningful in spaces up to about 225 sq ft
- Thermoelectric is inherently less efficient per pint than compressor designs
What owners report
Commonly praised
- Small, light and almost silent for closets and bathrooms
- Cheap to run
- Auto shutoff when the tank is full
Common complaints
- It removes only a small amount of water per day, so it suits tiny spaces only
- Some units fail shortly after the one-year warranty
- Customer service responses are inconsistent

Step-up pick
Vremi 22-Pint Dehumidifier
Compact capacity for apartments and single rooms.
Strengths
- 22 pints per day is honest capacity for up to 1,500 sq ft
- Smaller and lighter than 35 and 50-pint units, easier to move room to room
- Auto-defrost and continuous drain option at a budget price tier
Limitations
- Cannot keep up with a genuinely wet basement; capacity is the hard ceiling
- Smaller tank means more frequent emptying without a drain hose
- Build quality reflects the price; expect a shorter service life than premium brands
What owners report
Commonly praised
- Pulls a surprising amount of water from the air
- Affordable for small rooms
- Simple controls
Common complaints
- Noise bothers some, especially in bedrooms
- Some units arrive damaged or fail early

Questions, answered
Do mini dehumidifiers actually work?
In small enclosed spaces, yes: a closet or RV bathroom has little air volume, so even ounces per day of extraction moves the needle. In a real room, no: the capacity math does not work.
Thermoelectric vs compressor: which for small spaces?
Thermoelectric for silence and tiny spaces; compressor for actual rooms. Thermoelectric is less efficient per pint but has no compressor noise, which is the whole point in a closet or bedroom corner.
How often do you empty a mini dehumidifier?
The Pro Breeze's 16 oz tank in a damp closet typically needs emptying every day or two. The auto shutoff prevents overflows, but there is no continuous drain option at this size.
