Cleaning
You should clean your humidifier every 3 days, and when you're ready to store it.

Note:

• Never immerse the water tank cover in water or liquid. Do not place any part of the humidifier in a dishwasher.
• Do not use detergents to clean the humidifier.

1. Unplug the humidifier.
2. Remove the water tank cover by turning it counterclockwise.
3. Clean the transducer with a cotton swab moistened with room temperature water. [Figure 3.1]
   
4. Wipe the interior and exterior of the water tank with a soft cloth.
5. Dry all parts with a cloth. Make sure all parts are completely dry before reassembling or storing.

Descaling
Descaling removes any mineral deposits that may have built up inside the humidifier. Always descale the humidifier before and after storing for long periods of time.

1. Unplug the humidifier and pour out all the water.
2. Clean the transducer and water tank interior using distilled vinegar.
3. If the humidifier has thick scale buildup, scrub with a non-scratch scrub sponge.
4. Wipe off any remaining scale with a non-abrasive cloth, sponge, or cleaning brush.

Replacing the Cotton Bar

2. Remove the water tank cover by turning it counterclockwise. [Figure 4.1]

4. Flip the water tank cover right side up so that the cotton bar falls out.
5. Insert a new cotton bar into the cotton bar cover.
6. Replace the cotton bar cover cap by placing it back on and twisting it clockwise to lock it on.
   Note: We recommend replacing the cotton bar every month with consistent use. To purchase cotton bar replacements, search "USB humidifier replacement" online. Make sure the bars purchased are the correct dimensions (see Figure 4.2). Bars can also be trimmed to fit the humidifier if they are too long in height. Soak the cotton bar in purified water for 5 minutes before installing.

Reassembling
