How to clean your Holmes® Smart Humidifier with Wemo®, F7C046

Regular cleaning on your Holmes® Smart Humidifier with Wemo®, F7C046 is necessary to prevent the growth of mold, mildew, fungi, and bacteria in the unit.  These organisms can thrive in standing water that is left inside the device for more than a couple of days.  It is best to empty and refill the tanks on a daily basis, or keep the humidifier running throughout the day, to avoid standing water in your unit.

IMPORTANT:  Prior to performing any maintenance on the unit make sure to do the following:
  • Unplug the unit from the electrical outlet and then remove the tanks and empty them. 
  • Plug the unit back to the power outlet and then run the humidifier for approximately 4 hours on Medium setting or higher to dry out the wick filter and bottom tray.
  • Unplug the humidifier from the power outlet before cleaning the unit.

Cleaning the tanks

When the tanks are empty, you can clean the tanks through the side tank cap.  Simply use a long, bottle-type cleaning brush.  Do not remove the bottom tank cap.  This is a permanent fixture on the tank.  Carefully clean the plunger assembly at the bottom of the unit by wiping it with a damp cloth.

Cleaning the filter doors

The filter doors should be wiped down with a damp cloth when filters are removed to get rid of any dust or residue on the filter doors.

Cleaning the tray

When the filters are being replaced, you can also clean out the bottom tray.  Wipe the tray and dry it with a cloth or paper towel.  Be sure to thoroughly clean around all corners of the tray, as well as the float and the float arm.  You can use a one-to-one vinegar-to-water ratio to clean off any mineral build-up on the tray, float or float arm.  Proper cleaning prolongs the life and improves the performance of your Holmes Smart Humidifier.

Prevention of Mineral Build-up

One way to prevent minerals from building up in the tray and tanks is to to change wick filters regularly and to clean the tanks and tray regularly to avoid standing water.  You can also prevent mineral build-up by using water treatment solutions.
