Key Care Instructions for Your Humidifier

  1. Please note that the humidifier does not feature dry-burn protection. It should be filled only up to 0.08 gallons (300ml) and is designed to work for 6-8 hours on maximum mist setting. To prevent the unit from overheating and damaging the mist core, it's essential to refill it after the specified time.

  2. It's important to handle the humidifier carefully as it is not waterproof. Ensure that the humidifier remains upright during use to avoid water leakage into its electrical components, which could cause rust or damage to the mainboard or USB port and may prevent the device from powering up.


  • Inspect the micro-USB port of the humidifier (check for detachment, looseness, sinking, etc.), and pay attention to the orientation when plugging and unplugging;

  • Verify if the device can be powered on by long-pressing the "bulb" button on the humidifier for 2 seconds (as shown in the figure below).

    Check if the ambient light on the top of the humidifier lights up normally. Long-pressing for an additional 2 seconds can turn off the ambient light on the top.

What If There's No Mist Produced?

When water in the tank is used up, manually unplug the USB cable to cut off power, then add water to the humidifier.

  • Check if the water tank has water (maximum 0.08 gallons or 300ml);

  • After filling the humidifier with water for the first time, it takes approximately 3 to 5 minutes for the humidifier to start atomizing;

  • Verify if the cotton swab is completely wet; you can detach the cotton swab from one end of the atomizing piece, dip it in water, wet it, and restart the humidifier;

How to Troubleshoot Hey abby Smart Humidifier?


  1. If the mist volume at the top of the humidifier is very small (excluding the above-mentioned issues) or if there is a large amount of water around the top mist chip but no mist is produced, it may indicate abnormal issues with the mist chip, and the humidifier needs to be replaced.

  2. After the humidifier water tank is filled with water, it should not be tilted or placed upside down.
