How to clean a humidifier filter
Unplug your humidifier.
Before you disassemble your humidifier unit, make sure it's turned off and disconnected from the wall outlet. You're going to be handling a lot of wet parts, so this will help you prevent any accidents or damage.

Available options:
[-] In warm, dry environments, the temperature should never exceed 103 f (16 c). If it is warmer than this, try the open air humidifier.
[-] Choose a humidifier meant for use on bedroom and living room walls. Some humidifiers come with built-in, no-calve-type, filters.
[-] Choose a flat, water-resistant surface as your work area. A countertop near the sink is optimal.
[-] To remove the humidifier from the outlet, reach into the chamber and locate the face of the handle. Without removing the handle, disconnect the unit from the wall outlet.
