Hydro Mist is a compact, portable humidifier that's been designed to give off a gentle, cool mist of humidified air. Once you turn this device on, the humid air that it emits may soothe your nose and throat, potentially relieving allergies, along with helping eliminate unpleasant odors and bacteria from the air. Your Hydro Mist will only take up about as much space as a large coffee mug, and it'll make very little noise while it's running.

How to Use (Step by Step)

  1. Add Water to Reservoir

    To get started with this portable humidifier, pop off its top and fill the inner reservoir with water without letting any spill over the edge. You can fill it with virtually any type of water, regardless of whether it's from the tap, a water bottle or some other source. It's best if the water isn't extremely hot or cold, though.

  2. Plug In and Turn On

    Next, put the top back on and plug the humidifying device into electricity. Be sure that your device is resting on a flat surface so it won't fall over easily. Use the power button on the top of the device to turn it on, and it'll start giving off a cool, humidified mist within a second or two. You'll also notice that the color of illumination it's giving off will begin to shift.

  3. Enjoy Four Hours of Use

    Once your Hydro Mist is running, the water within its reservoir will provide you with a humidified mist for four or more hours at a time. After the reservoir is empty, you'll have to either turn off your device, unplug it and put it somewhere safe until you need it again, or refill its reservoir with more water.


  • Portable

    Hydro Mist is so portable that most users will be able to carry it from place to place within their home in just one hand. One of these devices will even fit into a car's cup holder, so if you've got some sort of electrical outlet to plug yours into, you'll be able to use it in your vehicle, too.

  • Quiet

    Each of these devices contains a small fan that will make hardly any noise as it moves and thereby delivers you the humidified air you desire. That means you'll be unlikely to disturb anyone else by using your Hydro Mist, even if they're sitting or lying down only a few feet away from you. If you choose to use your device in your bedroom, it also won't make loud noises that'll keep you up all night.

  • Color-Changing Light

    Your Hydro Mist will come equipped with a light that will change color by alternating among six different shades, such as red, blue and green. As with the noise of this device's fan, the gentle illumination the light provides won't keep the majority of people from sleeping, but it will allow this device to double as a night light. You'll likely appreciate the bit of brightness that it's able to give off if you fall asleep with the device on and then wake up needing to make a trip to the bathroom.

  • No Batteries Required

    This device plugs in, which means that you won't have to worry about keeping an appropriate set of batteries on hand in case the current set wears out.

  • Accommodates Essential Oils

    Many people will choose to fill this humidifier with water only, but if you want to add a natural scent to the air, you can add a few drops of essential oil to the device. You'll be able to add these right after you fill your device's reservoir with water, and the oil won't interfere with the effectiveness of the tool's inner mechanisms. Its aroma may overpower any foul smells that are present in the immediate environment. 

Positive Points

  • Fights Bacteria

    Things like allergens and other bacteria tend to float around dry, stale air, so humidifying the air directly around you with your Hydro Mist will help remove these things. That means they'll be less likely to affect you, and you may, in turn, feel physically better than you would in a room with drier air. The humidified air that comes out of each device may also have a soothing effect on your nose and throat, which may help you breathe better when allergies are stuffing you up.

  • Ideal For Work

    One of these devices is an ideal thing to put on your desk or in your cubicle at an office job since it'll enable you to change the air quality for yourself and not others. These devices don't have a far-reaching effect, so it's unlikely that your humidified air will reach the desk of a colleague who prefers dry air and cause them to get annoyed with you.

  • Handy During Travel

    Your Hydro Mist will likely come in handy when you need to travel, especially if you're headed to a hotel room that may be filled with stagnant, musty air. No matter where you're going, it's highly probable that you'll be able to fit your device and its small extension cord into your suitcase or carry-on bag. As long as there's an electrical outlet available, you'll be able to immediately get it out, fill it with water and use it at your new location.

  • Useful In Dorm Rooms

    The compact size of each Hydro Mist will make it a wonderful device to add to a college dorm room or even a small apartment. One of these will likely take up less space than your bedside lamp and will start working quickly to improve the air quality of the room. Since dorm rooms tend to offer a similar air quality to hotels, this may come as a relief to your nose, and you likely won't keep any roommates up all night by coughing and sneezing.

Negative Points

  • Requires Electricity

    You'll need a source of electricity to use your Hydro Mist, which means you won't be able to use it in some locations, such as certain cottages or campsites that aren't equipped with power. It's quite common to have an electrical outlet in one's car these days, but if you don't have one in yours, you won't be able to use this device in there, either. While it's great that you don't need batteries to run one of these devices, having the option of using them would be helpful.


  • Only Use Water and Oil

    The Hydro Mist humidifying tool has been designed to be filled with water and essential oils only. You should not fill it with any other type of liquid, even if you think it smells nice. Oils that contain any ingredients that aren't 100 percent natural should also be left out of the device's reservoir since chemicals could damage its insides.

Bad Battery

Took from Dec 13, 2022, to Feb 23, 2023, to receive, then after a few weeks of use the battery not holding a charge even plugged in.
Works great but feel it is money wasted due to battery issues.
Happy to start, but unhappy now.

Love It

I use one at home and the other two at both job sites. It has reduced my coughing from indoor allergens. I run it from the USB port on my desktop computers.
