How to Change the Wick/Filter in a Portable Humidifier

How to Change the Wick Filter in a Portable Humidifier

The wick filter (also called a pad or evaporative filter) in your portable humidifier plays a key role in adding moisture to your air. Over time, the wick can become clogged with mineral deposits and lose efficiency. Replacing it regularly keeps your humidifier running smoothly and your air properly humidified.

Here’s a simple, step-by-step guide that works for most portable humidifier models:

Step 1: Turn Off and Unplug the Humidifier

Before doing anything, make sure the unit is turned off and unplugged from the electrical outlet for safety.

Step 2: Remove the Water Tank

Lift off or slide out the water tank and set it aside. This will give you access to the filter compartment in the base of the unit.

Step 3: Open the Humidifier Base

Depending on the model, you may need to remove a cover or simply lift the top housing to access the wick filter. Refer to your owner’s manual if you’re unsure how to open the unit.

Step 4: Remove the Old Wick Filter

Take out the used wick filter. It may be wet, discolored, or stiff from mineral buildup. Dispose of it in the trash.

Step 5: Clean the Base (Optional but Recommended)

Wipe out the inside of the base with a soft cloth. If there’s any scale or slime buildup, clean with a solution of white vinegar and water, then rinse thoroughly.

Step 6: Insert the New Wick Filter

Place the new wick into the compartment exactly as the old one was installed. Make sure it sits securely in the correct position.

Step 7: Reassemble the Humidifier

Reattach any covers or components you removed and place the water tank back onto the base.

Step 8: Plug In and Turn On the Unit

Plug the humidifier back in and power it on. Make sure it’s operating normally and producing mist or humidity as expected.
