If your humidifier is not operating properly, you may need to replace the filter, which may have clogged with minerals and other deposits.

Do not fill the humidifier water tank with warm water, as this may cause leakage.


Do not place the humidifier on furniture, as the surfaces can be damaged by moisture.

The Holmes brand of electrical home appliances has been offered since 1982. Some of Holmes items include fans, heaters, purifiers and humidifiers. A humidifier can moisten the dry air in your home that occurs when the windows are closed and the heating system is running. Air that is too dry may cause respiratory problems or damage to your furniture. Know how to operate your Holmes humidifier properly so that you can start adding needed moisture back into your air.


Step 1

Place your humidifier on a flat surface and at least four inches away from the wall. Place the humidifier on a floor surface that will not be damaged by moisture.

Step 2

Remove the water tank from the humidifier by grasping the tank handle on the top of the machine and lifting it straight upward. Turn the tank upside down and remove the filler cap in a counterclockwise direction.

Step 3

Fill the water tank with cool water. Replace the filler cap by turning it in a clockwise direction until it locks into place. Turn the tank over and place it back in position on the humidifier.


Step 4

Plug the power cord into an outlet. Turn the dehumidifier on by pushing the "MODE/OFF" button once for "HI" manual operation. Push the "MODE/OFF" button again for "LO" manual operation. Turn the unit off by pressing "MODE/OFF" a third time.

Step 5

Press the desired humidity level (35, 40, 45, 50 or 55) on the control panel if you desire automatic operation. Press the "MODE/OFF" button to either the "HI" or "LO" setting. The machine will automatically turn on or off when the selected humidity level has been reached. Turn the machine off by pressing the "MODE/OFF" button.
