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 Frigidaire 22-Pint ($170) at 44 dB is the quietest option, while the Midea Cube 20 ($180) adds Wi-Fi and a much larger tank at 45 dB.

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 Frigidaire 22-Pint runs at just 44 dB, making it the quietest unit in the 20-pint class. It is a reliable pick for light sleepers. The Midea Cube 20 costs $10 more but adds Wi-Fi control and a 3.2-gallon tank (double the Frigidaire's 1.6 gal), so you rarely wake up to a full-tank shutoff.
