  • Product Overview

    Curb damaging humidity and stop mold in its tracks with the Sunpentown SD-31E 30-Pint Dehumidifier. The SD-31E is designed to treat small areas in your home up to 200 square feet optimally, but its benefits can extend to an area as large as 500 square feet. Place it in your bathroom, laundry room, bedroom, kitchen, or small basement to eliminate excess moisture. An automatic humidistat and a variety of intuitive control features make operation a snap. Plus, set up is easy, just slide it out of the box, plug it in, and start dehumidifying.

    Easy Automatic Operation

    With the Sunpentown SD-31E Dehumidifier, maintaining your optimal humidity is easier than ever. Simply choose your desired humidity level using the onboard humidistat, select Auto operation, and let the dehumidifier do the work for you. The unit dehumidifies until your desired humidity level is reached. Then, the compressor and fan power down to save energy. You can also run the SD-31E continuously, for example, when you need to dehumidify a particularly humid spot with little downtime.

    Added Features for Simple Daily Use

    The Sunpentown SD-31E 30-Pint Dehumidifier has all the features you need to take control of your home's humidity problems and manage them effectively. The 2-speed fan gives you your choice of dehumidifying speeds. A full bucket indicator with automatic shutoff lets you know when it's time to empty the reservoir and protects your home from damaging condensate spills. Take advantage of 2 draining methods, manual or continuous gravity draining, to suit the needs of your space. Plus, program the 24-hour timer to set a power on or shutoff time for your unit when you're not available. The SPT SD-31E Dehumidifier is packed with features and functions that take the headache out of operation.

    Additional Features

    • Electronic Controls - Choose your settings easily and precisely with the soft-touch electronic control panel.
    • Automatic Defrost - This dehumidifier operates successfully in temperatures down to 41 degrees F. However, if frost starts to build up internally, an automatic defrost function melts it quickly to reduce downtime.
    • Washable Air Filter - Clean your air and keep the dehumidifier running at peak efficiency with the onboard pre-filter. It's washable to help bring your maintenance costs down.
    • Automatic Restart - Following a power failure, the SD-31E automatically restarts using your previously programmed settings. This is a great feature to have when you'll be running your unit unattended.
    • Time Delay Protection for Compressor - A 3-minute time delay protects the compressor from unnecessary wear and tear as you start and shut off the unit.
    • Quiet Operation - This Sunpentown dehumidifier is among the quietest dehumidifiers available, emitting only as much sound a refrigerator "hum."
    • Carrying Handle and Casters - Transport your dehumidifier easily from spot to spot with the recessed carrying handles and smooth-rolling casters.
    • Energy Star-Qualified - The SD-31E is Energy Star-qualified for budget-friendly operation.


    The Sunpentown 30-Pint Dehumidifier stops damaging humidity in its tracks, eliminating excess moisture from small spaces like your bathroom, bedroom, laundry room, and more.

    What Customers Love

    • Set It and Forget It - A humidistat plus auto operation makes it easy to maintain your desired humidity level with no intervention.
    • Energy Star-Compliant - Energy Star-compliant dehumidifiers use about 15% less energy than non-Energy Star dehumidifiers. This can help reduce your energy bill. 

    Things to Consider

    • Pump Option - Add a condensate pump accessory when pump drainage would work better in your space. For example, you might need to pump condensate upward through a window.

          Takes moisture out and that means the air conditioner runs less. Great product.

              My house is 1400 sq. ft on 2 floors, no basement-have a full attic. We use this on the 1st floor to keep the dampness out on humid or rainy days. It is quiet and easy to empty.
