  • Question: How do I clean my Vicks Mini Filter-Free Cool Mist Humidifier?

    Answer:

    To properly clean your humidifier, we recommend the separate processes of Scale Removal and Disinfecting shown below. These two processes must be performed separately. All maintenance should be done in the kitchen or bathroom on a water-resistant surface near a faucet. DO NOT wash any components of this humidifier in the dishwasher. 

    Scale Removal 

    1. Turn off and unplug the humidifier. 
    2. Remove Water Tank from Base. Remove Tank Cap, taking care that black rubber Cap Seal does not come off. Empty water from Water Tank and Base. 
    3. If accessory is installed, remove accessory and set aside. DO NOT clean accessory. This will damage the accessory. 
    4. Add 2 cups of undiluted distilled white vinegar to Water Tank. Replace Tank Cap and swish vinegar solution around in Tank. Place Tank on Base. Vinegar solution will drain into Water Reservoir and loosen mineral buildup (scale) on Nebulizer and Float as they soak in the solution. It will also loosen scale on bottom of Water Tank. 
    5. Soak for 15-20 minutes. 6. After soaking, unlock Tank Cap and pour solution out in sink. Pour solution from Water Reservoir out in sink. Wipe Nebulizer and Float with soft cloth to remove loosened mineral deposits. 
    6. Rinse Water Reservoir and Water Tank until smell of vinegar (for Scale Removal process) or bleach solution (for Disinfecting process) is gone. Make sure water does not enter the fan opening (vented opening in back of base) or Power Knob. 

    Disinfecting 

    Follow Steps 1-3 in Scale Removal Instructions in previous section. 
    For Step 4: Add ½ tsp of bleach to ½ gallon (1.9L) of water and add to Water Tank. Replace Tank Cap. Swish solution around in Tank. Place Tank on Base. Bleach solution will drain into Water Reservoir and will disinfect Water Reservoir and other components as they soak. NOTE: Using more than 1 tsp. of bleach per gallon of water may result in damage to your humidifier. See steps 5-7 in Scale Removal Instructions in previous section to complete Disinfecting process. NOTE: DO NOT mix vinegar and bleach solutions together. Scale Removal and Disinfecting must be done separately. 

    Why is there white dust?
    With an ultrasonic humidifier, a built-in nebulizer vibrates the water at ultrasonic frequency which causes the water droplets to break into a fine, cool mist that you can see. In hard water areas, we recommend using demineralization cartridges with your ultrasonic humidifier to capture minerals in the water and to help reduce white dust on surfaces.
