Important Instructions:

Please read and follow all of the manufacturer's instructions before using, cleaning or storing this humidifier. Here are some highlights:

  • Place unit on a firm, level, flat surface.
  • Position unit to not blow directly on objects or plants.
  • Do not place the unit near a heat source, such as a stove, heater or radiator.
  • Do not run the unit without the Mist Outlet in place. The Mist Outlet can be removed for cleaning.
  • Unplug the unit before filling or cleaning.
  • Do not touch the water in the base, as temperature can reach 92°F.
  • Use care to avoid spills when filling, moving or cleaning the water tank.
  • Do not pour water through the top Outlet Air Grill onto the Power Head.
  • Do not put anything into the water tank except cool, clean water.
  • To prevent the growth of microorganisms in the tank:
    • Turn the humidifier off if the relative humidity exceeds 60% (the manufacturer recommends the use of a hygrometer [humidity monitor] to gauge accurate relative humidity levels in the room).
    • Do not leave water in the tank if the unit will be turned off for more than 12 hours.
    • Do not leave water in the tank when storing.
  • Do clean and disinfect the water tank periodically following the manufacturer's instructions.
  • For daily maintenance, use only water and mild detergent.
  • Do not submerse the base of the unit in water or pour water onto the unit.
Note: Do NOT add any additives to the water (such as water conditioners or aroma fragrances), as these can affect the performance of the transducer and/or damage the plastic water tank. Using such additives will void the Manufacturer's Warranty.

Mineral Cartridge:

The Vornado® Ultra1 humidifier comes equipped with one (1) Vornado® Mineral Cartridge. The cartridge removes minerals from the water, reducing harmful mineral buildup on the unit's ultrasonic transducer.

Note: To ensure the performance of your humidifier, replace the mineral cartridge using only a genuine Vornado® Mineral Cartridge – part # MD1-0018 (sold separately).
  • Initial Use:

    • Soak cartridge in a water bath for 24 hours prior to initial use – the cartridge must absorb water to reach maximum performance.
    • Refer to the Owner's Guide for installation and further instructions.
    • Note: It may take the humidifier a few minutes to create mist with the initial use of a new Mineral Cartridge.
  • Mineral Cartridge Replacement:

    • The Mineral Cartridge collects minerals and other impurities, and will require replacement over time. Various factors can influence the frequency of replacement, including amount of use, water quality and hardness, and other factors.

    • The control panel on the humidifier will display REPLACE MINERAL CARTRIDGE after 800 hours of operation. To reset the notification, simply press and hold the Power button for 3 seconds.

    • Vornado has also provided the following approximate replacement guidelines:

      • Once a month – recommended for heavy or continuous use.
      • Once every 2 months – recommended for lighter or intermittent use.
      • Earlier than above – if white powder residue settles around the unit.
    • When storing the humidifier, remove and discard the Mineral Cartridge.
Note: If you live in a hard water area or if the water used in this humidifier has been treated by a decalcification system, the manufacturer recommends using distilled water instead of tap water. Use of hard or decalcified tap water can produce a fine white dust that can settle on objects. Distilled water can help eliminate or limit the amount of white dust.
