  • Product Overview

    Experience the therapeutic effects of gentle warm mist and the ease of no-hassle operation with the Honeywell HWM-340 Easy-To-Care Humidifier. This warm mist humidifier adds up to 3 gallons of soothing warm moisture to your space each day, helping naturally relieve your cold symptoms, allergies, and uncomfortable dry air symptoms. The Honeywell HWM-340W is ideal for humidifying large rooms and spaces such as living rooms, large bedrooms, dens, and offices. Unlike conventional warm mist humidifiers, this model features an easy top-fill reservoir, low-maintenance, filter-free operation, and simple humidistat control, among many other helpful features.

    Germ-Free Warm Mist

    Available in black or white, the Honeywell HWM-340 Humidifier disperses a comforting warm mist that is 95% bacteria-free. Once you fill the water reservoir, water is drawn into the boiling chamber. Inside the chamber, boiling action helps separate minerals from the water and kill bacteria, creating healthy purified moisture. For added relief, this humidifier includes a medicine cup for liquid respiratory medications. Add Vicks/Kaz Steam Inhalant or Vicks VapoSteam.

    Adjustable Humidistat

    The HWM-340 is one of the few warm mist humidifiers available that features an adjustable humidistat that maintains your comfort setting. Simply turn the mist control dial to 1 of 2 output settings. Once you have reached a comfortable humidity level, slowly turn the knob until you hear a click. The humidistat will then automatically maintain the humidity level you have selected. You also have the option to run the humidifier continuously for nonstop mist in your space.

    Easy Top Fill and Dishwasher-Safe Parts

    Some conventional humidifiers literally leave you straining to fill them and annoyed by routine maintenance. Not so with the Honeywell HWM-340. With a top-fill reservoir, filling it is as easy as watering a plant. Plus, an illuminated water window always lets you know when it's time to refill. Some parts of the HWM-340 are even top-rack dishwasher-safe for more convenience when it's time to clean.

    Additional Features

    • Easy Top Fill - Filling this humidifier is as easy as watering a plant. No straining!
    • Refill Indicator Light - An indicator light illuminates when it's time to refill.
    • Runs Up To 24 Hours - Set on low, the Honeywell HWM-340 runs up to 24 hours continuously on a single fill.
    • Ultra-Quiet Operation - No internal fan means this Honeywell humidifier is virtually silent and ideal for use overnight.
    • Some Parts Dishwasher-Safe - Maintenance is easier when you can drop some parts right in the dishwasher. The humidifier's top cover, mist chimney, and water float are all top-rack dishwasher-safe.


    The Honeywell HWM-340 Easy-To-Care Warm Mist Humidifier provides warm, germ-free moisture that naturally soothes cold symptoms, allergies, and dry air discomforts.

    What Customers Love

    • Large Area Coverage - It's unique to find a warm mist humidifier that covers large rooms and spaces. The HWM-340 is large enough to humidify living rooms and large bedrooms.
    • No Filters - Filterless operation means no costly filter replacements or the hassle of remembering when it's time to replace them.

    Things to Consider

    • Use with Caution Around Children and Pets - Warm mist humidifiers may pose a slight burn risk because of the boiling chamber located inside. Keep this unit out of reach of children and away from curious pets.
