Care & Maintenance

Cleaning the Water Tank

Make sure the humidifier is completely 

unplugged from any power source while 

cleaning.

1.  Turn off and unplug the humidifier.

2. Remove the water tank from the base 

and pour out any excess water. Fill 

the tank with 2 cups of distilled white 

vinegar and 2 cups of water; replace the 

cap and gently shake the tank to coat all 

of the sides.

3. Fill the inner chamber with ½ cup of 

distilled vinegar.

4. Allow the vinegar to soak inside both 

the water tank and inner chamber for 30 

minutes. 

5. Use a soft-bristled brush to clean any 

scale buildup outside the water tank and 

in the inner chamber.

6. Pour out the vinegar from both parts of 

the humidifier and thoroughly rinse with 

warm water.

7. Dry all parts with a dry, clean cloth. 

Make sure all parts of the humidifier are 

completely dry before reassembling and 

storing in a covered space. 

NOTE: The water in the inner chamber 

near the transducer may still be warm 

after turning off the unit. Use caution when 

pouring out the water. 

Cleaning the Tourmaline Ceramic Filter

It is recommended to clean the tourmaline 

ceramic filter every 6 months, depending 

on how often you refill the water tank. 

1.  Remove the water tank cap from the 

humidifier. 

2. Detach the tourmaline ceramic filter 

from the cap by twisting the cap 

counterclockwise.

3. Rinse the filter under clean water, and 

allow it to dry in the sun for at least one 

hour.

4. Once the filter is dry, replace it back onto 

the water tank cap.
