How this dehumidifier scores for different use cases
At 6.2 lbs and compact dimensions (14x6x8 inches), this fits well in closets, RVs, and small bathrooms. The 2-in-1 humidifier/dehumidifier combo adds versatility for tight spaces with varying humidity needs.
Sleep mode with under 40 dB noise and LED light shutoff make it decent for bedrooms. The humidifier combo adds comfort control. However, very low capacity limits effectiveness in humid climates.
With only 1 liter per day (about 0.5 pints) capacity, this unit cannot handle basement moisture. It lacks auto-defrost and has minimal coverage for large basement spaces.
This unit removes roughly 0.5 pints per day. It cannot manage moisture for a whole house. Coverage area and capacity are far too small for this use case.
No Wi-Fi, no app control, no voice assistant support, and no remote control. This product offers zero smart home capabilities.
A 70-watt semiconductor dehumidifier with 1 liter/day capacity is completely unsuitable for commercial or industrial moisture removal needs.
Our Verdict
The Hoomace HB641 is a mini semiconductor dehumidifier. It removes about 0.5 pints of moisture per day. That is a tiny fraction of what full-size units pull.
This machine works best in a closet, small bathroom, or RV. Its 70-watt draw barely dents your power bill. The 2-in-1 humidifier mode adds flexibility for dry seasons.
Sleep mode drops noise below 40 dB. The 7-color LED light adds ambiance. You can drain water through the included hose or the 102 oz tank.
At $129.99, the price sits high for this capacity class. Many compact dehumidifiers with similar specs cost $40 to $80. You pay extra here for the humidifier combo.
Do not buy this for a basement, large room, or whole house. It simply cannot keep up. The 1 liter per day limit makes it a small-space-only tool.
If you need light humidity control in a tight space, it works. For real moisture problems, you need a compressor-based unit with 20+ pints per day.
What We Like
- 2-in-1 design works as both humidifier and dehumidifier in one unit
- Sleep mode keeps noise under 40 dB with lights off for quiet nights
- Lightweight 6.2 lb body fits easily in closets, RVs, and small rooms
- Continuous drain hose included so you can skip emptying the water tank
- Only uses 70 watts of power, which keeps your electric bill very low
What Could Be Better
- Removes just 1 liter per day, far below the 20+ pint average for standard dehumidifiers
- No humidity display to show you the current moisture level in your room
- No timer function to schedule when the unit turns on or off
- No Wi-Fi, app control, or remote control for hands-free operation
- No wheels or carry handle despite being marketed for moving between rooms

Frequently Asked Questions
Common questions aboutDehumidifier,2 in 1 Humidifier Dehumidifier Combo,102 OZ Water Tank Dehumidifiers for Home Bedroom,Basement Bathroom,Auto Shut Off,Sleep Mode,7 Colors LED Light
How much water does this dehumidifier remove per day?
It removes about 1 liter (roughly 0.5 pints) per day. This works for small spaces like closets and RVs but not for large rooms or basements.
Can I use this in my basement?
No. The 1 liter per day capacity is far too low for basement moisture control. Basements typically need a unit that removes 30 to 50 pints per day.
How does the 2-in-1 humidifier mode work?
The unit switches between dehumidifying and humidifying. When your air is too dry, turn on the humidifier. When it is too humid, switch to dehumidifier mode.
Do I have to empty the water tank manually?
Not if you use the included drain hose. Connect the hose for continuous draining. You can also use the 102 oz (about 0.8 gallon) tank and empty it when full.
How loud is this dehumidifier?
In sleep mode, noise stays under 40 dB. That is quieter than a whisper. The semiconductor technology runs much quieter than compressor-based dehumidifiers.
