    What Is a Warm Mist Humidifier Used For?

    Warm mist humidifiers simply boil water and then release it as warm steam, which increases the humidity. The main benefits of these popular units are:

    • Healthy: Warm mist humidifiers are considered as beneficial to our health due to the boiling process killing bacteria. They also give you a better chance for a clear airway (1).
    • Quiet: Not having a fan inside warm mist humidifiers means they operate quietly. This makes them ideal for peaceful humidification and night-time use.
    • Size: Unlike cool mist humidifiers, warm mist humidifiers are smaller and thus, more suitable for small spaces like your bedroom or office.

    Take Note

    Warm mist humidifiers should be used with caution due to the presence of boiling water. Keep your warm mist humidifier away from pets, children and the elderly.

    Finding the Best Warm Mist Humidifier

    With all the advantages of warm mist humidifiers, you still need to factor in certain aspects before committing. Consider the following points:

    Home Size and Coverage Capacity

    To decide on a mist humidifier, first measure the square footage of your space. Bear in mind that too much moisture can breed more bacteria and mold, and you need an ideal humidity level of between 30 and 50 percent (2). Getting a product that’s too big for the space you’re humidifying will create too much moisture.

    It’s fruitless buying a product that won’t cover your entire home. In contrast, you don’t want those high humidity levels by getting a model that’s too overbearing. With this in mind, only get a product suited to your home’s footprint.

    Output Levels

    Strike a balance between the space you need humidifying and the output level of the unit. For example, if your space is 400 square feet, it’s no use getting a model that has a low output level over 24 hours. You need that moisture hitting the entire area as quickly as possible.

    Most reasonably priced humidifiers are capable of handling rooms of approximately 200 to 500 square feet. The more expensive ones can do double the work, but do you need that?

    Cleaning and Maintenance

    The humidifier’s role is to assist you in living a healthier life, but the last thing you want is to have to maintain the unit constantly. It’s supposed to make your life easier, not bring more hassle.

    So, give good consideration to the shape, filter, tank size, and the entrance to the water tank or the filter. Our research showed us that many users complained how narrow the tank entrance was, making refilling their unit a real pain.

    Take Note

    Another challenging part to clean is the tube. Some humidifiers have an auto-cleaning feature that removes remaining moisture by itself. If not, a long, thin brush is required to do this job.

    The Best Warm Mist Humidifiers of 2020

    Choosing the best warm humidifiers demanded a lot of research. We piled hours into this, combining industry trends, user reviews and our own knowledge and experience.

    These are the top warm mist humidifiers on the market:

    1. TTLIFE Ultrasonic Warm Mist Humidifier

    Safest Warm Mist Humidifier

    TTLIFE 6L Warm and Cool Mist Humidifiers for Large Room Baby Bedroom, Humidifiers with Remote, Essential Oil, Customized Humidity, LED Touch Display, for Your Family
    Check Price

    This popular ultrasonic warm mist humidifier provides you with a strong capacity of 1.45 gallons.

    It’s reported that this capacity allows it to run continually for 40 hours, so you won’t need to refill it constantly.

    There’s a clear focus on health and safety with this model. It’s made from BPA-free plastic, has a built-in resin filter and can soften hard water.

    Why We Love It

    Sleep Mode

    The sleep mode is really handy for generating a mist in the night with the LED light switched off. This makes it an excellent choice for light sleepers and little ones.

    It combines well with the aromatherapy option. You can add essential oils to the aroma box for a calm and pleasant aroma during the night — or day, of course.

    Rotating Nozzle

    Dual 360-degree rotatable nozzles are also included in the model. They spread the mist in all directions with a speed of 550 ml/hour, thus humidifying all parts of your room.

    Built-In Ionic Generator

    This humidifier purifies the air and releases fresh air into your space. Thanks to the special integrated ionic generator, you and your family can breathe better. You can also enjoy a healthier life by preventing secondary pollution.

    Keep In Mind

    Disturbing Noise

    Due to the automatic humidity sensor, users report that the machine automatically activates and is disabled every couple of minutes. This creates an annoying noise disturbance.

    Additional Specs

    Working HoursUp to 40 hours
    Tank Capacity1.45 gallons
    Max. Mist OutputUp to 550ml per hour
    Dimensions24.8 x 19.7 x 15 inches
    Room Coverage430 to 753 square feet

    2. Levoit LV 600HH Hybrid Ultrasonic Humidifier

    Best Large Warm Mist Humidifier

    Check Price

    If you’re willing to pay a little more money for some amazing extras, the Levoit LV 600HH Warm Mist Humidifier is just made for you.

    Levoit is a well-known and respected brand in the humidifier market. This model is especially crafted for large spaces as it releases 500ml of moisture per hour. With that, you can definitely reach the targeted humidity in no time compared to other humidifiers.

    The manufacturer also didn’t miss out on adding an essential oil tray. So, now you can add your favorite scent to your room to enjoy the calm, humidified atmosphere.

    Why We Love It

    Extra Options

    Levoit has taken humidifier technology to the next level by adding a remote control to the device. This allows you to control the unit without disturbing your comfy lounge position.

    Besides, its humidity sensor gives you the chance to control the desired humidity level. There’s also an automatic shutdown option once the humidity reaches your preferred level.

    Large Tank Capacity

    Unlike most humidifiers, Levoit has a water tank capacity of 1.5 gallons, which allows it to work up to 36 hours non-stop. This should make your life easier since you won’t have to worry about refilling it in the middle of the night.

    Mist Settings

    This machine gives you the two mist settings to enjoy all through the year:

    • Cool mist: Recommended in the summer to protect unmoisturized skin and hair from the summer heat.
    • Warm mist: Great for easing cold symptoms.

    Keep In Mind

    Overheating

    With all the advantages of this Levoit unit, it has a reported problem of releasing extra moisture in the vicinity. To counter this, place it on a towel and keep it away from anything that could be damaged by water — especially electrical equipment.

    Additional Specs

    Working Time12 to 36 hours
    Tank Capacity1.5 gallons
    Max. Mist OutputNot specified
    Dimensions11.3 x 7 x 10.5 inches

    Are you searching for an excellent humidifier for temporary relief from cold and flu symptoms? The Vicks Warm Mist Humidifier could be your hero. It’s popular for releasing a soothing vapor into the air quickly and efficiently.

    This model is perfect for medium to large rooms. Its tank capacity of 1 gallon can cover up to 500 square feet. The transparent tank is excellent for checking the water level — no second-guessing when it needs refilling.

    Why We Love It

    Portable

    The Vicks V745 is well-built, and easy and safe to use. It’s especially lightweight and compact, meaning it’s incredibly portable around your home.

    Aromatherapist

    We all enjoy a house that smells nice, but chemical sprays can wreak havoc on health. With this humidifier, you can breathe the natural fragrances of your favorite essential oils.

    Simply add a few drops to the medicine cup, and the device circulates the oil through the water, releasing it all over your house. This same process can be applied to medical inhalants to relieve flu and cold symptoms.

    Auto Shut-Off

    As the humidifier starts running out of water, the device will shut off immediately to prevent dry burning. This is very useful, particularly if, during the night, the humidifier runs out of water and you forgot to top it up.

    Keep In Mind

    Leaking Problems

    Few people complained about leaking problems after a few months of usage. This seems to have been caused by critical design flaws of certain units.

    Additional Specs

    Working TimeUp to 12 hours
    Tank Capacity1 gallon
    Max. Mist Output2 gallons per 24 hours
    Dimensions12 x 7.9 x 14.2 inches

    Why We Love It

    Affordable

    HMW705B is not only saving your money because of its price. It’s also energy-efficient and will keep your electricity bill low. Also, being filter-free saves ongoing filter replacement costs.

    Easy Control

    One of its added benefits is having a low water indicator, which will save you the worry of when to refill it. We love its 1-gallon capacity and the automatic turn-off system. With those, you can go through the entire night knowing that your unit is working away.

    Breezy Cleaning

    Due to its accessible parts, it’s easily cleaned and refilled. Just soak the machine for about 15 minutes in vinegar, and dust off the device with a brush.

    Keep In Mind

    Not the Quietest

    Users report that the boiling noise can be frustrating. However, the good news is that once the water has boiled, the unit operates quietly for a comfortable atmosphere.

    5. Crane USA Classic Warm & Cool Mist Humidifier

    Cleanest Warm Mist Humidifier

    Crane USA Classic Warm & Cool Mist Humidifier - White
    Check Price

    This Crane model is mainly popular due to its being antimicrobial. A runtime of up to 72 hours means there’s less frequent maintenance to be done.

    A humidifier shouldn’t replace healthy eating and drinking water for helping with cold and flu symptoms. Nonetheless, this model reportedly assists when you’re ill. One way it does this is by alternating between the cold and warm mist options.

    Why We Love It

    Soothing Mist

    For when you have a cold, this Crane model can run for up to 72 hours. This is ideal for a consistent and soothing warm mist to alleviate some cold symptoms.

    You can alternate between the warm and cold mist setting to suit your specific needs at any time. Just be patient to wait for the transition between the two.

    Clean Control

    An antimicrobial protection system with silver particles coats this humidifier’s body. This prevents the spreading of mold and bacteria, which can be common in humidifiers due to the presence of moisture.

    Two Mist Options

    The flexibility of having a warm and cool mist option is excellent for versatility in the summer and winter.

    This can help in reducing heating bills. The warm mist provides a warm blanket feeling in the winter, and the cool setting substitutes for AC in the summer.

    Keep In Mind

    Bright Lights and Noise

    The LCD is super bright, so it’s best to not have this one on at night in the bedroom. While Crane says this model has a whisper feel, many people complain that it’s too noisy to work at night.

    Additional Specs

    Working HoursUp to 55 hours
    Tank Capacity1.2 gallons
    Max Mist Output2.5 gallons per day
    Dimensions17.5 x 11 x 11.5 inches
    Room CoverageUp to 500 sq. ft.
