Instructions for use:

  fill the water tank with water (no more than the water level line), wait for 3-5 minutes and then turn on the mist switch (there are cotton swab in the humidifier, and it takes 3-5 minutes to absorb the foot). Essential oil cannot be added to the humidifier, and perfume or alcohol soluble in water can be added in a small amount (but it is not recommended to add it). Cotton swab does not need to be changed regularly, depending on personal usage, I think it is yellow and dirty before I need to replace it.
