    To deep clean your machine, first, disinfect its base using three-percent hydrogen peroxide or white distilled vinegar. Here's what to do:

    • Unplug your unit.
    • Remove the unit's water tank and filter.
    • Pour a generous amount of hydrogen peroxide or white distilled vinegar into the base.
    • Use a clean toothbrush to scrub away film and mineral build-up.
    • Next, let the liquid sit in the humidifier’s base for at least 10 to 30 minutes.
    • Pour the liquid out.
    • Rinse by adding and swishing fresh water to the base. If any mineral residue is left, repeat the entire process.
    • When the base is clean, air dry.
