BLACK+DECKER 30-Pint Dehumidifier Review (BDT30WTA Model)

The Black+Decker BDT30WTA portable 30-pint dehumidifier is an energy star certified low-capacity dehumidifier that is designed for the smaller areas of your home such as bathrooms, basements and laundry rooms.

The dehumidifier is effective as long as the area it will be used in is within the capacity of a low-powered dehumidifier. Running a dehumidifier with an insufficient capacity in a large room will result in wasted energy and poor results.

This dehumidifier features a modern and clean appearance. You can operate it via simple electronic controls and can monitor it from an LCD digital humidistat display on the control panel. This unit is a compact dehumidifier ideal for areas where space is a luxury and can operate in cool temperatures, however, it is not fully effective at lower temperatures. The three fan speed settings available on this unit allow you to choose the lowest noise level or effective water removal mode that suits your circumstances.

BLACK+DECKER Compact Design

This portable 30-pint dehumidifier from Black+Decker is a compact unit that measures just 10 inches by 13.4 inches by 19.5 inches. At 35.1 pounds, this unit is relatively light and is fitted with a carry handle and castor wheels that should make it easy for most people to move it around as required.

Continuous Drainage

Considering the compact dimensions of the unit, it is inevitable that the water collection container size will be limited and some people may find that its capacity of just 8.5 is inadequate. This means that you may be required to empty the water collection container at least 4 times daily; in drier air, at least once a day. If you are not keen on doing this, take advantage of the continuous drainage feature provided by this Black+Decker dehumidifier.

All you have to do is attach a small hose to an outlet port in the dehumidifier’s casing and run the hose to a nearby sump or drain. The continuous drainage system works through gravity so your drain or sump should be close by and the hose angled towards the floor. You may have to place the unit a foot or two above floor level for improved water flow.

Automatic Restart

A useful feature of the BDT30WTA dehumidifier, which is not always available in many portable dehumidifiers, is the auto-restart option. If there is a power supply interruption to the unit, it automatically restarts once power comes back on. This feature is a great option if the dehumidifier is placed in a remote location where you cannot monitor it every day.

Automatic Defrost

The auto-defrost feature of this portable dehumidifier is often misunderstood – sometimes, even misrepresented. In general, when a room’s temperature falls, ice forms on the evaporator coils of the dehumidifier, this scenario can happen even when temperatures are within the 65 degree Fahrenheit range.

Ice should not be allowed to form since it will degrade the dehumidifier’s efficiency, ultimately damaging the unit. A special sensor detects the ice in the unit and turns off the compressor. When ice has melted, a process accelerated by airflow from the fan, the sensor restarts the compressor, resuming the dehumidification process. This feature aids the dehumidifier to operate without the risk of damage if temperatures fall below 41 degrees Fahrenheit.


The Black+Decker portable 30-pint dehumidifier is an outstanding home humidifier and is ideal for smaller basements and other rooms in your home. However, if you have a larger basement, you will need a larger dehumidifier, and if you have a cool basement, then this dehumidifier is not a good choice either.
