How To Clean

For warm mist humidifiers, it is important to keep the heating element clean. When minerals build up on the heating element it may cause it to overheat and shut off. To keep your humidifier running efficiently, clean it regularly. Weekly cleaning is recommended. All maintenance should be done in the kitchen or bathroom on a water resistant surface near a faucet. To properly clean your humidifier, we recommend the separate processes of Scale Removal and Disinfecting.

Before Cleaning:

If the humidifier has recently been in use on the warm setting, wait at least 20 minutes for unit to cool before beginning the cleaning process.

  1. Turn off and unplug humidifier. Never clean the humidifier when it is running.
  2. Remove Water Tank and empty completely. Remove any accessories from the water tank.
  3. Ensure Chimney is removed, then pour water from the Base into the sink. Be sure to pour out of the side of the Base to avoid leaking into the Control Panel.

Replace Chimney and Chimney Cover before beginning the cleaning process.

To clean the humidifier:

Scale Removal (Mineral Buildup)

  4. Let the heating element soak in the vinegar for at least 20 minutes. Never turn the unit on while you are cleaning. If there is excess mineral buildup on the heating element you can soak for several hours or overnight. 
  5. While still soaking in the vinegar, take a soft bristled brush and scrub off any minerals on the heating element.
  6. Gently wipe Nebulizer, Heating Element and Reservoir area with a soft cloth or paper towel to remove loosened minerals.
  7. Empty and rinse thoroughly with water until the smell of vinegar is gone.
