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, this Amazon number one best-seller is 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.
“On a scale of 1 to 5, I rate this product a definite 5! This is our second pure humidifier—we now have one in each of our 2 kids rooms—and you can’t beat the quality for the price. It’s silent, easy to clean and with 2 output settings, is great because one of our kids has a large room and the other is small.” —J. Cline
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.
“We have owned many humidifiers in this house over the past five years. We’ve had everything from the fancy to the cheapest ones we could grab at Walmart. They all end up the same, in the trash because they get disgusting. Our newborn became sick with an upper respiratory infection and we needed a new humidifier again, stat. This is a great quality and easy to maintain humidifier. I only wish we had purchased it sooner. It’s quiet, has a large tank that’s DISHWASHER SAFE and super easy to keep clean in general.”—Lauren Nicole
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.
“I used to get a sinus infection every winter that gets bad and turns into pneumonia. I started running a cool mist vaporizer in the bedroom as soon as we have to turn the furnace on in the fall/winter. The winter sinus infection stopped—I didn't wake up with everything in my throat and nasal passages feeling dry.”—SS
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. Plus, it has over 1,000 positive reviews from customers who say it’s super efficient at controlling the humidity level in their homes.
“Been using this humidifier for almost two years now and could not be happier with it. After years of trying out multiple different units, which all resulted in issues with mildew building up, filters being disgusting, and the humidifiers not really doing their job, this one really works. No more waking in the middle of the night with dry coughing and feeling like a lizard with dry skin. This product has dramatically improved our lives.”—Honest Reviewer
Best for Large Bedrooms: LEVOIT Hybrid Ultrasonic Humidifier
If you need complete peace and quiet as you sleep, this humidifier is the perfect solution.

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. It’s no wonder this savvy humidifier has almost 1,000 perfect five-star reviews on Amazon.
“It is fantastic that this humidifier can blow hot steam, because it rises up and pretty much bathes my face when I am sleeping at night. I stopped getting bloody noses, started sleeping better at night without sinus problems, and it has a large enough capacity that I can sleep the entire night with it blasting at the 60% setting on max steam and it won't run out of water. Very easy to control, and nice to be able to drop some lavender essential oil sometimes when I need to relax.”

Other standout features include an essential oil tray to add soothing aromas, a blue LED night light, and an automatic shut-off.
“This is the best humidifier I've ever purchased. Puts out a nice heavy spray (scented if you purchase the scents pack, which I recommend). If you fill it, it lasts through the night and more. I now breathe easier because of this pro.”—Mac
Best Warm Air: Honeywell Filter-Free Warm Moisture Humidifier
Unlike cool mist humidifiers, you can actually see the warm, soothing mist this design creates.

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.
“Compared to my past warm moisture humidifiers, this humidifier seems very well designed. Sturdy handle. Easy to fill from our bathroom sink faucets. Well-functioning valve. Plenty of output for its size. Subtle yet effective indicator lighting. Reliable auto-off when [the] water level is very low. Performance as expected + very competitive price = solid value.”—Haynes
Best for Diffusing Essential Oils: Homasy Cool Mist Humidifier

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). You can also set the mood with optional lighting in seven different colors.
“This humidifier is great!! It’s so hard to find a humidifier that you can add essential oils to. This one is easy to set up and easy to use. It’s so nice to just lift the lid and pour water in.
