  • When should I use the humidifier?

    The Hey Dewy humidifier is great for your morning bathroom routine, in a car during your commute to work, at your workstation connected to your computer/laptop, overnight at your nightstand, and so much more!

  • How do I plug in the humidifier?

    There is a USB that can connect to any standard port in a computer, car, or charger; the other end has a mini-USB that connects to the humidifier for power.

  • Can I turn off the night light?

    Yes! The night light is an optional feature that can run with or without the mist.

  • How long will it spray?

    After filling up with water, the spray can last up to 10 continuous hours. When in the intermittent mode, it can last twice as long. Please note that there is an auto shut-off feature after 8 hours, which can simply be turned back on with the push of the power button.

  • What type of water works best?

    Pure, filtered water works best on our device. Distilled water may work, though some types may be too fine, cause excess dripping. Tap water may also work well, as there is a built-in system to ensure impurities are filtered before converting to mist.

  • Am I allowed to use essential oils?

    It is not recommended to use anything other than water (distilled/purified is best, though tap water would suffice). Essential oils could damage the device.

  • How do I clean it?

    Simple water rinsing of the inner cavity on a regular basis would be effective. For breaking up any hard water buildup around the spout, you may gently brush the area under running water, using a small brush (like a toothbrush).

  • Can I travel with it?

    Absolutely! The Hey Dewy humidifier is made for the on-the-go individual. It is compact and lightweight, and can be used in a car, airplane, hotel and more. Give it a go!
