Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy, but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed products and single out the most convincing ones. (You can learn more about our rating system and how we pick each item here.)

And while we’ve written about the dry-air essential before — including the best USB-friendly models, a germ-free humidifier, and even de-humidifiers — here, we’ve rounded up the best humidifiers, as praised by the most enthusiastic reviewers on Amazon.

Best-rated humidifier

Pure Enrichment Ultrasonic Humidifier

More than 9,000 reviewers give this humidifier five stars, and many love how easy it is to use. “Just fill with water and push the button,” one says, adding, “No assembly required. It has four settings that produce high/low volumes of ‘mist’ with various states of blue LED illumination.” And though the blue light from the LED is controversial, as many think it’s hard to sleep with it on, those two levels of output are described as “useful when adjusting for different-sized rooms,” according to one customer. And nearly a third of five-star reviewers also note how quiet this machine is, with one saying it’s “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.” Even if you don’t think you need a humidifier, one reviewer thinks you should get it: They weren’t suffering from any sinus issues but still found themselves “sleeping much better, being more alert throughout the day, and having more energy.”

“This little humidifier is smaller than a water bottle,” reports one reviewer, and that compact footprint allows this humidifier to be functional in a variety of spaces. “I like that I can use it in my SUV or in my bathroom,” one customer writes, while another says it’s perfect for their desk at work. “This is small and unobtrusive; stays out of sight and does its job without a lot of attention drawn to itself,” they explain. “It turns off after the water has been depleted, which is important because I’m sure I’ll forget to turn it off when I leave my office, and I wouldn’t want to come back to a desk fire.” Nearly 20 percent also think it’s great for travel, too. “The small size fits into our cup holder perfectly, and the USB cord is long enough to reach the plug and operate just fine while traveling,” one reports. And even though it’s small, many agree that it’s plenty powerful. “I used it for nine hours today and never had to refill it,” says one user. “It’s easy to set up, quiet, and I like that I have the option to use with or without the changing lights.”

“FINALLY …. A humidifier that actually lives up and exceeds to what the manufacturer says it will do,” says one reviewer, who’s just one of many customers overjoyed by this do-it-all humidifier. “Whisper quiet? You can’t even hear it running when it’s sitting a foot away from you. Programmable humidity setting? Yep, anywhere from 45 percent up to 80 percent. Large capacity water tank? This could run for DAYS if you want, or only a few hours — it’s up to you. Warm or cool mist? Just push the button for the one you prefer. Aromatherapy option? It’s totally got you covered. Remote control? Ditto,” lists one reviewer. All of these features get the seal of approval from an experienced humidifier buyer, too. “We have four different humidifiers in our home, and this one is by far our favorite,” they write. “The settings are easily adjustable, no leaks, it’s stable, it’s quiet — no problems.”

Best filterless humidifier

A selling point for more than 10 percent of reviewers is that this humidifier does not require a filter, which in turn makes it easier to clean and maintain. “The filters were a bother; the cleaning was a bother, and difficult for me, with the shortness of breath to contend with as well,” one writes.
“So here comes the Vicks Filter-Free model and I could NOT be more pleased.” However, many reviewers warn that without the filter, you need to use filtered water “so you don’t have any buildup in the bottom of the device,” recommends one user. But after all the necessary precautions, reviewers are impressed by how well this works — especially in large spaces. “My wife and I live in a 2,000-square-foot apartment and have had this humidifier running full blast for 24 hours a day for almost a week and it works great,” one writes, while another says, “We run two all winter long in a 1,500-square-foot apartment and it really helps.”

Best humidifier for the bedroom

This humidifier’s efficient “sleep mode” is beloved by reviewers, because it “is almost dark with a dim indicator that shows it is powered on.” One reviewer writes, “The sleep mode is perfect and it auto shuts off with a little waterless icon indicator. Makes it easy for even the kids to know when to fill them.” It’s also very quiet, making for ideal sleeping conditions: “It was so quiet, I didn’t notice [it was on] until I saw the mist rising. Very quiet. There is a tiny gurgle every now and then as air bubbles rise, but that is a negligible sound.”

Best cool mist humidifier


“This is my first cool mist humidifier and I’m so impressed,” writes one satisfied reviewer. “It’s super easy to refill and when I run it continuously on the lowest setting it will usually produce mist for over 24 hours.” Another reviewer, who moved from Los Angeles to Las Vegas, says this humidifier is the only thing that’s help alleviate some of the worst symptoms of the drier climate: “Since my time in Las Vegas I find that my allergies have been getting worse. My nose has been so dry to the point that it was hurting to blow my nose. I’ve had the Ultrasonic Cool Mist Humidifier for three (3!!!) days and I cannot believe the power of this little thing. My dry nose has cleared up miraculously and the best part is that it’s not sore to the touch which what was bothering me the most.”

Many reviewers also praise the humidifier’s durability. “The components and parts seem really high quality, especially after buying some cheaper options which I’ve found to be incredibly chintzy and fragile” writes one user, adding, “I have had zero problems with mine and would highly recommend it!”

“Whether you want a strong stream of mist sent right over your head (like I do) or only a small amount this one should fit the bill,” says one reviewer who thinks the best part of this humidifier is the cool mist, which can break up congestion and be used year round versus warm mist humidifiers that are meant more for wintertime colds. Another common use of a cold mist humidifier is for helping to prevent bloody noses. One customer bought this specific model off his doctor’s recommendation, writing, “I have had the humidifier for a week, and I have to say that I am so much more comfortable now. My dryness is gone and no more stuffiness or bloody noses.” He calls it a “a snap to use.” And another customer agrees that it’s easy to operate. But for her, the most useful quality is that “the water take usually lasts two to three nights,” so she doesn’t have to constantly fill it up. Plus, she adds, “I love the fact that I can change the amount of mist coming out.”

Best dual-nozzle humidifier

TaoTronics TT-AH002 Humidifier

This product has two nozzles that can be aimed in different directions for more even coverage, and reviewers often cite the utility of the dial-knob to control how strong they want the vapor. As one reviewer put it, “This thing rocks! It puts out more mist than Snoop Dogg puts out smoke in the green room.” It’s a good pick for rooms with low ceilings, as one reviewer notes that with this nozzle, “the cool air goes forward and not straight up, which for me that is important since our bedroom has a low angled ceiling. So if the air went straight up it would get our ceiling damp. We now use it nightly for our dry air bedroom and it works very well. One nozzle is pointed toward my husband and the other nozzle towards my way.”
