With over 72,000 reviews and a 4.5-star rating, and being an Amazon's Choice pick, this humidifier comes highly recommended. It runs for up to 25 hours of continuous operation, has an optional night light, comes with an automatic shutoff feature, and works best in medium-size rooms or smaller.
What a reviewer says: "Love the small humidifier I purchased—I use it in a bedroom and it makes a tremendous difference! So quiet you don't know it's on and provides just the right amount of moisture to keep me breathing easy all through cold weather months."

If you're looking for humidifier for a large room, this one's for you. This can run for 50 hours nonstop, has auto mode so it adjusts by itself, has a remote control and timer, and gives you the option to choose from warm or cool mist.
What a reviewer says: "First, I love this humidifier. We have four different humidifiers in our home, and this one is by far our favorite. The settings are easily adjustable, no leaks, it's stable, it's quiet, no problems."

We've included this product on our list of best essential oil diffusers, but surprise! It's also a humidifier, too. The cool mist humidifier changes colors, acts as a night light, has programmable on and off cycles, and has an auto-shutoff feature.
What a reviewer says: "One of the best aspects about this little humidifier is that you can fill it, turn it on and forget about it. Since the humidifier turns off automatically when the water is out, you do not need to worry about it running while dry. Based on our experience, if you are planning on using this as a humidifier, then it is definitely best suited if you place it within a few feet of where you'll be located."

You don't have to worry about this humidifier keeping you up at night—it's so quiet. It features multiple mist settings and a 360-degree rotating nozzle. There's also a dial to allow you to control the mist output and direction.
What a reviewer says: "I bought this humidifier hoping it was going to suit my needs. I wanted something small, easy to use, very quiet, and one that would not run out of water overnight. I got all those things. And the price was amazing at that."

For Dyson fans (or those who dream of owning a fancy vacuum), the brand also makes a humidifier. This one doesn't come cheap, but it does double-duty by moisturizing the air and keeping it cool. It has intelligent climate control, so it is smart enough to measure the temperature and humidity of the room and adjust accordingly.
What a reviewer says: "We live in Southern California, so it tends to get very dry during the spring and summer seasons, especially when you are running the A/C all the time. The Dyson humidifier really did the trick in normalizing the moisture in our 1,100-square-foot condo. Gone are the days of waking up with dry lips and a sore scratchy throat."

Honeywell's humidifier is ideal for medium-size rooms and can run up to 24 hours. The compact size makes it easy to fit on a desk or nightstand.
What a reviewer says: "We've owned this humidifier for 3-plus years now and today when I was filling it up I thought I should write a review because I still love it! We use it probably about 30 days or so a year whenever our kids are sick with congestion. It really helps their breathing at night. It is so easy to clean and maintain."

This humidifier also has an essential oil tray so it can give off your favorite scent. This one works in rooms up to 500 square feet (great if you're living in a studio apartment!) and runs for 50 hours nonstop.
What a reviewer says: "This humidifier hands down is the best one I've bought so far. It functions well without any hiccups, and the cherry on top is its massive volume so I don't have to fill it as frequently."

Park this humidifier in your bedroom and watch it work its magic on sore throats, allergies, and more. It has a four-liter tank, so it can run for 40 hours without refilling. There's also a 360-degree rotating nozzle, and you can set the preferred mist level with one touch.
What a reviewer says: "I can say without a doubt, this is the best ultrasonic humidifier I have owned to date. I love the durability of it, ease of use (only has three settings and that's all you honestly need), and I easily clean it every other morning before leaving for work (empty reservoir and tank, and wipe down with a microfiber cloth). This machine makes it so easy. Oh, and it looks amazing no matter where you put it."

Both a humidifier and a diffuser, this device is the best of both worlds. It delivers up to 30 hours of runtime on the lowest setting and up to 12 hours on the high setting.
What a reviewer says: "I was looking for a humidifier that I could use for my plants as well as my family. This humidifier is perfect. It's extremely quiet, which is great for when you use it while sleeping. And it takes essential oils. I don't really know anything about essential oils, but this humidifier plus eucalyptus oil was helpful when we were sick and it helps with my husband's allergies at night."

If you want a warm-mist humidifier, you might want to look into this top-reviewed one from Amazon. It has a one-gallon tank and can run continuously for 24 hours. And this one is extra helpful if you're sick—it comes with a medicine cup so you can put in a liquid inhalant.
What a reviewer says: "Realizing that my room was so dry, I started running the humidifier anytime that I'm in my bedroom. Within an hour of cranking the humidifier on the highest setting, the room reaches a very comfortable 40% humidity. Anywhere between 30-50% humidity is a comfortable range so I try and keep the humidity right in the middle. I am no longer waking up to a sore throat or dry mouth after using this humidifier."

With over 25,000 ratings and 4.5 stars, this is another winning aromatherapy-humidifier combo. It has seven different LED light colors, various mist modes, and an auto-switch so it doesn't overheat.
What a reviewer says: "This is the second of these humidifiers I've purchased—I loved the first so much that I wanted a second, particularly for my plants. I live in a studio apartment, so this humidifier isn't big enough to get the entire room. I run the humidifier all day and all night; I'd say it lasts a good 12 hours before it needs refilling, but it might even be longer than that. I never knew it was possible to be so passionate about a humidifier, but I did a lot of comparative research before purchasing, and I believe this humidifier has several features that make it a good buy."
