  • Our take on the Sunpentown SD-350

    The Sunpentown SD-350 is a small thermoelectric dehumidifier for tight spaces: closets, bathrooms, RVs and small rooms up to about 130 sq ft. It draws 65 W, holds roughly half a gallon in its tank, and shuts off automatically when the tank fills. Its 8 x 4.9 inch footprint and 13 inch height let it sit where compressor units cannot. Thermoelectric units like this pull far less moisture than refrigerant dehumidifiers, so it suits mild, enclosed spots rather than damp basements.

    What reviewers say

    Owners of small thermoelectric dehumidifiers like this generally report modest moisture removal and frequent tank emptying, but praise the size and low noise in closets and RVs.

    What people mention
    • Moisture removalCriticisedOwners say it pulls only a small amount of water, far less than a compressor dehumidifier.
    • Tank sizeCriticisedThe half-gallon tank fills quickly in muggy air, so it needs frequent emptying.
    • SizePraisedIts narrow footprint lets it go in closets, cabinets and RV corners where bigger units will not fit.
    • NoisePraisedReviewers find it quiet enough to run in a bedroom or closet without disturbance.
    • BuildMixedOwners describe a basic plastic build that works but feels light for the task.

    Questions and answers

    Is the Sunpentown SD-350 worth it for a closet?
    Yes, if the space is small and enclosed. It keeps a closet or bathroom from feeling damp, but it will not dry out a basement.
    How does it compare with a compressor dehumidifier?
    Compressor units remove several times more water per day and work better in warm, humid rooms. The SD-350 wins on size, weight and low power draw.
    Does it have a continuous drain option?
    No. It relies on its roughly half-gallon tank and shuts off automatically when full, so plan on emptying it regularly.
    How much area can it handle?
    Sunpentown rates it for about 130 sq ft. Treat that as a ceiling for a closed, mildly damp space, not a humid open room.
    How loud is it?
    The maximum is 46 dB, about the level of a quiet conversation. Most owners find it unobtrusive in a closet or bedroom.
    Does it work in cool rooms?
    Thermoelectric units lose effectiveness as temperatures drop. It performs best in warm, enclosed spaces rather than cold garages.
    Where is the Sunpentown SD-350 cheapest?
    At The Home Depot, for $47.70, as of our latest check.
