Overview
Moiswell makes the Defender MP145 as a commercial-style dehumidifier with a built-in pump and drain hose for crawl spaces and water damage restoration. It has automatic defrost, automatic shutoff, a timer and adjustable humidity control.
The reason to look at it is the big coverage area and the pump that removes the need to empty a tank. The limit is the conflicting capacity data and the weight of the unit.
Who it's for
Homeowners and restoration crews dealing with big damp spaces will use the pump and timer. Anyone with a small room or limited power should look at a smaller model.
Pros and cons
- Large rated area
- Built-in pump and drain hose
- Energy Star certified
- Longer cover on dehumidification system
- Capacity figures conflict
- Heavy at its listed weight
- Care steps not listed
- Single fan speed
Performance notes
A refrigeration system chills air to pull moisture out, and the built-in pump pushes the water through the drain hose instead of filling a tank. Automatic defrost clears frost in cool spaces, and a timer sets run periods. Rated area and airflow together decide how fast a basement dries.
