Best Dehumidifier for a Bedroom
For bedrooms, noise is the deciding factor. A 20-pint unit handles most bedrooms up to 500 sq ft. The Midea Cube 20 ($180) at 45 dB is the quiet pick, and its 3.2-gallon tank means no middle-of-the-night full-tank shutoffs. The Midea 22-Pint ($170) is the slimmer, cheaper alternative.

Understanding Your Needs
A humid bedroom leads to poor sleep, dust mite proliferation, and that sticky feeling on sheets. The key requirement here is noise level: anything above 50 dB will disrupt sleep. The quietest 20-pint units run at 44-45 dB, roughly equivalent to a whisper or a quiet library. Tank capacity also matters at night because a full-tank auto-shutoff at 3 AM means you wake up in a humid room. A large tank or continuous drain setup avoids this problem.
Why These Picks
The Midea Cube 20 runs at about 45 dB, roughly whisper-level, and its 3.2-gallon tank means you rarely wake up to a full-tank shutoff. That combination makes it the strongest bedroom pick in the 20-pint class. The Midea 22-Pint costs $10 less and runs quietly in a slimmer, classic shape; hook its hose socket to a drain and it never interrupts your sleep with a full tank.
