  • Product Overview

    Capable of humidifying areas as large as 120 square feet, the Honeywell HCM-890B Humidifier is an affordable solution for dry indoor environments. The compact tabletop model is perfect for small living spaces like bedrooms, dens, and home offices. With a 2-gallon per day output capacity, the Honeywell HCM-890B disperses an invisible cool mist into the air for up to 12 hours on a single fill. With evaporative technology, the humidifier also features an automatic moisture balance system that adjusts output to the ideal level of moisture for your air.

    Versatile Operation

    With 2 output settings, the Honeywell cool moisture humidifier is ideal for controlling the humidity levels in the smaller living spaces in your home. The fan pulls dry air through an antimicrobial filter and releases water vapor in the room as an invisible cool mist. Simply fill the water reservoir tank with water, choose your desired fan setting, and you're ready to go.

    • 2 Output Settings - Rotate the fan setting knob to High for maximum moisture output. For quiet operation or for use at night, turn the fan setting to Low.
    • Safe for Kids Rooms - Cool moisture makes this tabletop humidifier a safe option for children's bedrooms and nurseries.
    • Self-Regulating - For your convenience, this self-regulating humidifier adjusts moisture output automatically as the humidity levels in your room rise or fall.

    Easy Maintenance

    The clear-view water tank on this Honeywell cool moisture humidifier allows you to watch water levels drop as you enjoy the comfort of balanced humidity levels. Equipped with a comfortable tank handle and a large tank opening, the 0.8-gallon reservoir is easy to refill and is dishwasher safe. Regularly rinsing the replaceable Protec antimicrobial filter with water helps prolong its use.

    Additional Features

    • Energy Star-Certified - This Energy Star-certified and UL-listed humidifier effectively humidifies small-sized rooms without sending your energy bills soaring.
    • Use Tap Water - The Honeywell HCM-890B Humidifier uses regular tap water, eliminating the need to purchase distilled water.
    • 3-Year Warranty - This durable tabletop humidifier comes with a 3-year limited warranty.


    The Honeywell HCM-890B Cool Mist Humidifier adds soothing invisible moisture to help relieve your cold and allergy symptoms and keep you comfortable all winter long.

    What Customers Love

    • Self-Regulating Output - Evaporative humidifiers like this one naturally adjust moisture output to the precise amount of moisture you air can hold at its current temperature. No more guessing!

    Things To Consider

    • Noisier than Other Types - Evaporative humidifiers are slightly louder than other types because they use an internal fan. If you're looking for a quieter humidifier, consider one of Honeywell's ultrasonic models.
