From Vicks to Honeywell, these humidifiers have over 32,000 reviews combined.
Keep waking up with dry skin and stuffy sinuses? It’s officially time to find the best humidifier for your home.
These handy machines regulate a dry environment by adding moisture back into the air. Ideally, your home will sit at the optimal humidity level of 40 to 50%, as Princess Ogbogu, MD, director of allergy and immunology at The Ohio State University Wexner Medical Center, previously told Health.
When humidity is added back into the air, it not only helps dry nasal and sinus passages, but can also make a big difference in how you look and feel, according to Clifford W. Bassett, MD, medical director of Allergy and Asthma Care of New York. Having the right humidity level in your home and bedroom makes it easier to breathe (especially when you’re sick), prevents skin from dying out, and can even improve your sleep.
For a lucky few—typically those living in newer homes— humidifiers have been built into their HVAC system. But for the rest of us, a humidifier is a household necessity for tackling dry air—especially in the winter—and a much more affordable alternative to uprooting your home’s entire heating and cooling system.
Before shopping for a humidifier, you’ll want to decide if you’re looking for a warm or cool mist machine. Warm mist options create steam by vaporizing water with heat. Typically faster at humidifying spaces than their cool mist counterparts, warm mist humidifiers can be used with soothing medicinal vapors, but can be a bit loud due to the bubbling of heated water.
You’re more likely to find cool mist humidifiers on the market, because the lack of heat makes them a safer choice for homes with children or pets. They require regular thorough cleanings, but also tend to be quieter.
There’s two types of cool mist humidifiers: ultrasonic or evaporative. An ultrasonic humidifier, which is the quietest option, uses high-frequency vibrations to create mist, while the evaporative option uses a filter and fan to release water vapor into the air. The latter are less likely to grow mold, but require you to replace the filter occasionally. An ultrasonic humidifier doesn’t use a filter, but will need a thorough scrub every month.
When picking the right humidifier for your space, you’ll want to ensure the product is powerful enough to cover your desired square footage (and for the desired length of time). Large humidifiers that are best for the whole house, like AIRCARE Whole-House Humidifier ($147, amazon.com), can cover up to 2,400 square feet—while smaller, portable options and single room humidifiers are great for more confined spaces like the car or your bedroom. Many humidifiers on the market can run for over 8 hours at a time (and have built-in auto shut-off for safety), so you can create the ideal humidity level in your home and bedroom.
To help you narrow down the search, we’ve compiled a list of the 13 best humidifiers on Amazon, according to customer reviews. With thousands of five-star reviews between them, these top picks include everything from the best bedroom humidifiers for sleeping to high-tech options you can control through your smartphone to the best one for your sinuses.

Best Overall: Pure Enrichment MistAire Ultrasonic Humidifier
This ultrasonic humidifier uses high-frequency sound vibrations to create a cooling mist for up to 16 hours. Between a super quiet operating system, automatic shut-off, and optional night light setting, it’s a great pick for a bedroom, nursery, or any medium-sized room in your home. You can even customize the modern tank to your space by selecting your ideal misting speed (low or high) and using the 360-degree nozzle to direct mist away from sensitive areas, like upholstery or plants. Best of all, the user-friendly design means the tank is super easy to refill and clean.
“I have always had a humidifier in my home but this has got to be my all time favorite,” a reviewer wrote. “I love the size because it fits nicely on an end table and [can be] easily moved to any room in the house. It is easy to fill with water and doesn't become heavy or awkward to place on the base. I found it very easy to clean. The unit is completely quiet: If you didn't see the mist you would think it was off. I love everything about this humidifier.”
Best for Winter: Honeywell Germ-Free Humidifier
When flu season rolls around, you’ll be grateful for this “germ-free” humidifier which uses UV light technology to automatically kill up to 99.9% of bacteria that could be lingering in the unit’s water. The large one-gallon tank means the machine is powerful enough to cover spacious rooms and can humidify your home for up to 24 hours—so you can tackle the woes of winter, including nasal congestion, coughs, and dry skin, without having to deal with constant upkeep. Available in both a black and white finish, this humidifier is also a great pick for anyone worried about over-humidifying their air: The tank uses evaporative technology, so the machine won’t expel more moisture into the air than it can hold.
In fact, a parent reviewing the humidifier revealed it’s the only thing that stops their son from coughing or having a runny nose at night—something they discovered after forgetting to turn it on one night. They also shared that it’s not too noisy and doesn’t emit a sound any louder than a white noise machine.
Best for Sinuses: Vicks Cool Mist Humidifier
The 1.2-gallon tank uses ultrasonic technology to quietly restore moisture to the air for up to 30 hours. Each humidifier also comes with two Vick Vapors packs, so you can opt to add soothing aromatic vapors to your mist—whether that’s a plain menthol scent or a sleepy time blend. Plus, there’s automatic shutoff when the water runs out, and the wide tank makes for easy cleaning and refilling.
One reviewer who suffers from sinus dryness, which leads to pain, found this product’s cool mist put an end to their discomfort. They used the humidifier in a large bedroom with 16-foot ceilings and discovered it could easily conquer the massive space.
Best for Whole House: AIRCARE Whole-House Humidifier
Skip the mismatched collection of humidifiers scattered around your home by purchasing a whole-house humidifier that can cover up to 2,400 square feet. You can select both your ideal humidity level and fan speed, and the digital humidistat will automatically shut off the humidifier once the pre-chosen humidity level is reached. While it definitely has a large footprint (the machine is just over two feet tall), it’s shaped like a sleek pedestal and the tiled top can be customized to fit your home decor.
“Attractive, compact, [and] easy to assemble. Once the home reaches the humidity level desired, the unit seldom comes on—and I live in near desert conditions,” one shopper wrote. “The price was awesome. It was far more than I expected for the money or for a whole house humidifier in general. I've recommended it to several people already.”
Best for Large Bedrooms: LEVOIT Hybrid Ultrasonic Humidifier
If you need complete peace and quiet as you sleep, this humidifier is the perfect solution. Not only is the machine whisper-quiet, but you can turn the LED screen off completely to ensure your room stays pitch black. Depending on the season, choose between either warm or cool mist to humidify spaces up to 753 square feet. An ideal pick for larger bedrooms, it also has an intelligent mode that uses a built-in sensor to keep humidity at the optimal 40-to-60% range. Plus, there’s an option to put essential oils into the aroma box.
“I have had at least 4 other humidifiers, and this is the best so far,” a reviewer raved. “This humidifier works wonders in our 11 by 13 foot bedroom. With central heating in Boston, our apartment's humidity was around 20%, which wreaked havoc on my sinuses, hair, and skin. During the worst months of winter we always kept this full and running continuously. It actually increased the humidity in the room, finally getting up to 35% was a miracle, and I have been sleeping much better. I like the high capacity and have recommended this specific humidifier to friends because it works great.”
Best Ultrasonic: Pure Enrichment Hume XL Ultrasonic Humidifier
This ultrasonic humidifier with a nearly perfect 4.7-star rating on Wayfair can quickly humidify spaces up to 270 square feet for as long as 50 hours. The ultrasonic technology used to create the mist stands out from other designs by skipping the need for expensive filters, which saves money in the long run. But the innovations go beyond the interior: Its sleek exterior—a contemporary brushed metal exterior that’s fingerprint-resistant—also suppresses noise for a near-silent operation. Other standout features include an automatic shut-off and node mode, which dims all LED control panel lights.
“I have used many humidifiers due to my allergies. The Hume XL Ultrasonic Cool Mist is by far the best,” one reviewer wrote. “I love that this holds so much water and it lasts longer than any I've tried. I also love the 2 nozzles on top. I just can't say enough good things and I wholeheartedly recommend this to everyone!”
Best Warm Air: Honeywell Top-Fill Warm Moisture Humidifier
Unlike cool mist humidifiers, you can actually see the warm, soothing mist this design creates. Slightly louder than ultrasonic options, this warm mist humidifier heats the air to create a steam-like vapor in medium-sized rooms for up to 24 hours. When the tank runs out, the machine will automatically shut off and a refill light will illuminate. You can also optimize the tank to meet your needs in the wintertime by choosing your ideal moisture output and adding vapors through the medicine cup.
Reviewers say this warm mist humidifier will be a lifesaver during cold winters thanks to its quick setup and plethora of settings that make it easy to personalize based on your space and needs. They also revealed the tank holds enough water to run continuously all night on even the highest settings—and with its super quiet design, you’ll actually want to!
Best for Diffusing Essential Oils: SpaRoom AuraMist Essential Oil Humidifier
PSA: Not every humidifier can process the addition of essential oils—and those that can don’t always do it well—but this cool mist humidifier is a major exception. The unique design allows you to directly mix your favorite essential oil blend directly into the water tank and even comes with a 100% pure Eucalyptus oil to get your aromatherapy started. The no-frills, simplistic design operates with a single touch button that lets you choose between a high mist, low mist, and sleep mode (which is low mist with all lights turned off).
“I went through 3 humidifiers in 2019 this by far is the best!” one shopper shared. “I’ve searched high and low for a large tank that I can add essential oils to—I ruined one because the oils deteriorated the plastic. This machine is excellent quality and the tank lasts forever! I have mine constantly running in my bedroom due to allergies and dry coughing at night and the lavender and eucalyptus smell makes me feel like I’m relaxing at a spa.”
Best Budget: Holmes Cool Mist Humidifier
Designed for small rooms, this budget-friendly find proves you can still get all the smart features of a higher-priced humidifier without breaking the bank. Just like many pricier models, it offers multiple speed settings and an automatic shut-off. Beyond an easy-to-fill removable tank (which holds enough water to run continuously for 24 hours), it also runs air through a triple-layer filter powered by baking soda to eliminate impurities and reduce odor. Reviewers say this results in a practically invisible mist. In fact, with the whisper-quiet operation, you might not even realize it’s running.
One reviewer said it was the best purchase they’d made in awhile, writing that they planned to purchase additional units for other rooms in their home beyond the bedroom. They also raved about its tank capacity and revealed it runs about 12 hours on the highest setting. Plus, it’s got a doable noise level.
Best for Travel: HoMedics Personal Ultrasonic Humidifier
If you’re a frequent traveler, this super versatile mini humidifier is a great pick for adding moisture back into the air on the go. Small enough to fit into the palm of your hand, it runs off USB power from a laptop or wall outlet, and the compact, portable size means it’s easy to bring with you anywhere. To use, simply screw off the top, add water to the fill line, plug in, and press start. It will run continuously for up to five hours—so you can enjoy the soothing benefits of a humidifier even while you’re in a hotel room.
A reviewer explained, “Because of dry air in hotel rooms, I wanted something packable to help bring some moisture into the room: This unit is quite small, easy to fill and clean, and creates mist for 4+ hours. [It] also shuts off if I fall asleep before it does!”
Best for Purifying: Brondell O2+ Revive Cool Mist Evaporative Console Humidifier
Instead of investing in both an air purifier and humidifier, opt for this multi-purpose pick that acts as both. Its fast-acting purifier swiftly moves air through two HEPA (High-Efficiency Particulate Air) filters—a special standard developed by the U.S. Department of Energy that requires a filter to remove 99.7% of all particles at least .3 microns in size—along with an odor-trapping carbon filter and gas-reduction filter. The evaporative humidifier then restores moisture back into air to keep your space refreshed. In warmer weather, you can drop the humidity level down to moderate or simply opt for no humidity at all.
“I got my Brondell air purifier when I moved to the city and the first night I used it I slept better,” wrote a 5-star reviewer. “I felt better and my overall health has improved over the months I've used it. I love the air humidifier and it puts the perfect amount of humidity in the air. I got one for my son's room since he has bad allergies and he's breathing fine and not using his inhaler.”
Best Personal: Innerest Portable Humidifier
The slim design of this portable humidifier makes it the perfect size to fit into a standard car cup holder. When winter rolls around and you need to heat up your car, this tiny “magic cup” will be a lifesaver that adds moisture back into the air for an exponentially more comfortable environment. The construction is also foolproof: just add the ultrasonic humidifying stick to any cup of water (though it’s best used with the included one), plug into a power source, and switch on after 3 minutes. It’s also powered by USB, so you plug into your car, laptop, or even a powerbank for easy use on the go.
One reviewer raved: “Got it delivered yesterday. My wife had just started feeling all the cold and flu symptoms. Coincidentally, my wife felt better! She used it last night and bye, bye cough!”
Best for Sleeping: Oskar Evaporative Humidifier
Your friends won’t even realize this modern console is actually a humidifier at first glance, making it the perfect bedside companion. The environmentally-friendly pick uses just 2 gallons to effectively humidify up to 540 square feet at either a low or high speed. Unlike other designs, it features dimmable LED lights and an ultra-quiet fan to ensure it only improves your sleep rather than disrupting it. Plus, it even has a fragrance dispenser to add your favorite soothing essential oil—lavender anyone?
“I bought this as a gift for my sister,” wrote one shopper. “She is very happy and says it works. She no longer wakes up with a stuffy nose.”
