2. Remove the cap and fill the water tank. Screw the cap back on, making sure the cap is correctly threaded. Your MESA holds .8 gallons of water.
   About water additives:
   • Do not add essential oils in the MESA water tank. Only add them to the essential oil tray.
   • Do not use water softeners.

3. Your demineralization cartridge is in your base. This helps break down the minerals naturally found in water – improving your air quality and preventing the white dust people sometimes notice with ultrasonic humidifiers. We recommend replacing your cartridge every 60-90 days. To do this, simply remove the water tank, take out the old cartridge, then drop in a  new one.
   

4. Put your MESA base on a level surface in the room where humidity is most needed. To avoid condensation, make sure the unit is at least two inches from the wall and not under a window. Put the water tank on the base.
   Note: The MESA is an ultrasonic humidifier, so it emits a very fine mist. Position the lid to direct this mist away from furnishings and electronics.

5. Put the essential oil pad on the tank next to the handle.
   Add a few drops of essential oil to the tray pad. Add more oil to your liking. Only use essential oils in the tray; any brand will work with the MESA. Put on the lid.
   

6. Plugin your unit and remove the plastic tab from the remote. Press the power button on either the unit or the remote.

7. Set your desired output level by pressing the power button on the unit, or the mist output button on the remote. Your  MESA has three output levels that are displayed on the power button by green (low), yellow (medium), and red (high).

8. Switch between cool and warm mist by pressing the + button on the unit or the mist temperature button on the remote. It will take the MESA a few minutes to reach the warm mist temperature. The + button will glow red when the MESA is in warm mode.

9. Turn on the nightlight by pressing the nightlight button on the unit or on the remote .
   That’s it! Your MESA is ready to use.

HOW TO CLEAN YOUR MESA

Regular cleaning is important for preventing mold, mildew, and other bacterial growth in your humidifier. It also keeps your  MESA working its best.

NOTE: Do not allow any liquid to get into the air intake while you are cleaning your MESA.

1. Let the unit run until it’s empty, then turn it off and unplug it.
2.  Remove the lid and the essential oil tray and pad. Set these aside.
3. Remove the tank and your demineralization cartridge. Throw your cartridge away if it is time to replace it. Otherwise, put it in a sink while you finish cleaning your MESA.
4. Pour out any remaining water from the tank and the base.
5. Fill the tank a little more than half-full with water and add 2 tablespoons of white vinegar. Pour a little of this vinegar-water mixture into the base.
6. Put the water cap back on, shake the tank, then let sit for 20 minutes.
7. With the mixture in the base, use a soft cloth to clean the inside of the base. Gently scrub the oscillator (the dark ring in the basin). Let sit for 20 minutes.
8. After 20 minutes, empty the water tank and base.
9. Dampen a sponge with white vinegar and wipe down the base, tank, essential oil tray, and lid. Rinse everything thoroughly.
10. Wipe everything dry and replace the demineralization cartridge, if needed. Then reassemble.

When storing your MESA, discard the used demineralization cartridge and clean the unit as described above. Dry the unit thoroughly, and store it in a temperature-regulated area. Do not install a new demineralization cartridge until you are ready to use your humidifier again.
