Whynter 40 Pint Dehumidifier

Model: RPD-401W | SKU: wh2639
  • Out of Stock - This item is not currently available to order.

  • Product Overview

    Energy efficient yet powerful, the Whynter RPD-401W Dehumidifier combines the best of both worlds, protecting your space from damaging humidity while keeping energy consumption low. This 40-pint dehumidifier is best for controlling humidity in smaller spaces around your home, from your bedroom to areas in your basement. Full-featured, the Whynter RPD-401W includes easy electronic controls, an automatic adjustable humidistat, 2 drainage options, 2 fan speeds, a 24-hour timer, smooth-rolling casters, and more.

    No-Hassle Humidity Control

    The Whynter 40-Pint Dehumidifier is equipped with an automatic adjustable humidistat for low-hassle "set it and forget it" operation. Simply set your desired humidity level—we recommend setting it between 45 and 50% for ideal indoor comfort—and the dehumidifier will automatically maintain that level. During operation, the compressor cycles on and off while the fan runs continuously to evenly distribute dehumidified air throughout your space.  The RPD-401W can also be set to dehumidify continuously to eliminate high humidity around the clock.

    Super-Efficient Moisture Removal

    Energy Star-compliant, the Whynter RPD-401W uses 15% less energy to remove the same amount of moisture as conventional non-Energy Star dehumidifiers. It's also built with a more efficient compressor, fan, and refrigeration coil to make low-energy dehumidifying possible. Features such as a 24-hour timer and an automatic humidistat with auto shutoff help you conserve energy further and keep your energy costs down.

    Additional Features

    • 2 Drainage Options - Empty the dehumidifier manually by removing the water bucket and emptying condensate or set up continuous gravity drainage using the included drain hose.
    • Electronic Control Panel - Displays both your set humidity and ambient room humidity. Easy pushbutton controls and clear indicator lights help you stay on top of operation.
    • Bucket-Full Indicator - When the water bucket is full, an audible alert sounds and the tank-full indicator light illuminates to let you know it's time to empty.
    • Auto Defrost - The Whynter 40-Pint Dehumidifier operates in temperatures as low as 41 degrees F. Should frost form inside the unit, an automatic defrost system melts it quickly so the unit can resume normal operation.
    • Auto Restart - In the event of a power failure, the dehumidifier restarts automatically using the previously programmed settings when power returns.
    • Air Filtration - A washable pre-filter and an antibacterial silver ion filter lightly clean the air, trapping dust and large particles and neutralizing airborne bacteria.
    • Quiet Operation - At its highest speed, the RPD-401W exerts 54 decibels, which is no louder than a quiet conversation.
    • Carrying Handle and Casters - A recessed carrying handle and smooth-rolling casters make it easy to move this unit from spot to spot.


    The Whynter RPD-401W Dehumidifier eliminates damaging humidity in smaller rooms and spaces easily and efficiently.

    What Customers Love

    • 24-Hour Timer - The timer lets you program both start and shutoff times unlike conventional home dehumidifiers that feature shutoff timers only.

    Things to Consider

    • Room Size - This Whynter model is best for solving light to moderate humidity problems in small- to medium-sized rooms.

    Product works as described. Wish it has a feature to turn fan and compressor off when programmed humidity level is reached. Compressor only shuts off now. Fan runs continuously when power is on.
