Vornado MD1-0018 Mineral Cartridge for Ultrasonic Humidifiers

• Removes calcium, lime scale, and other mineral residue from hard water
• Helps to prevent the release of "white dust" into humidified air
• Also prevents harmful mineral build-up inside the humidifier
• Replace cartridge every 1-2 months (or more often with very hard water)
• For use in all Vornado® Ultrasonic Humidifiers, including the Ultra1 and Ultra3 models

Role of the Vornado Mineral Cartridge:

All Vornado® ultrasonic humidifiers come 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.

General Instructions:

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 Owner's Manual 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 the 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.
