What fits in a 300 square foot room

These dehumidifiers handle single rooms, bathrooms, closets, and small offices. Tank sizes run from 25oz to 35oz, which means frequent emptying unless you place the unit near a drain.

Quiet operation and auto shut off

Most units in this range run at or below 30dB, which is about the level of a whisper. Auto shut off turns the unit off when the tank fills, so it does not overflow.

Lighting and display features

Several models include 7 colorful LED lights or a screen display. These help you see the unit in a dark closet or bedroom without turning on a main light.

Placement in small spaces

Small dehumidifiers fit on a shelf, floor, or countertop. Some include an air purifying function or negative ion mode for bedrooms and bathrooms.
