Dry air can cause an array of problems, ranging from irritated sinuses to nosebleeds to cracked lips. Fortunately, a humidifier is an affordable solution to add moisture to any indoor environment. There are quite a few things to consider when picking out a humidifier, such as ease of cleanup (bacteria growth can be a problem for these devices), type (evaporative, ultrasonic, or warm-mist), and size.
The most traditional type, evaporative humidifiers, use a reservoir, porous wick, and fan to put moisture in the air. The wick absorbs water from the reservoir, and the fan then aids in evaporation by blowing on the wick. Ultrasonic humidifiers use high-frequency sound vibrations to create mist and are quieter than other types of humidifiers. Often there’s no filter, which can lead to mineral scale deposits. For smaller areas, warm-mist models are often preferred, as they’re quiet as well. They boil water via an internal heating element, killing bacteria and mold in the process, before dispelling the warm mist into the room. Some machines help individuals who need a desktop offering for the workplace, while others represent full-home solutions and come loaded with antimicrobial features designed to limit bacteria growth.
Below are our picks for the best humidifiers for 2019. If you’re looking for a dehumidifier, check out our picks for the best of those as well.
Pure Ultrasonic Cool Mist Humidifier
The Pure Ultrasonic is one of the most popular humidifiers, and for good reason. With a 1.5-liter tank, it’s perfect for bedrooms, offices, and medium-sized rooms. The top-mounted clear tank lets you easily view its water levels, allowing you to keep track of your next refill time. However, considering Pure designed it to last 16 hours on a single tank, you shouldn’t need to replenish the humidifier very often.
The 360-degree nozzle offers quick and convenient speed and directional mist adjustments. The unit also shuts off automatically if it runs out of water, so you don’t have to worry about wasted energy if the humidifier empties while you’re out. The device doubles as a nightlight, too. Simply activate the nightlight, and the Ultrasonic produces a gentle blue glow that serves as a perfect nighttime ambiance in the bedroom. However, if you need a humidifier for larger rooms or the entire home, you’ll need a more powerful device. Due to its shape, the device can be difficult to clean if you don’t stay on top of the recommended weekly cleaning. Fortunately, it comes with a brush to make cleaning a bit easier.

Honeywell HCM350B Germ-Free Cool Mist Evaporative Humidifier
The Honeywell HCM350B is another solid option. This unit boasts three separate speed settings, allowing you to more aptly control not only humidity levels in your home, but also the noise level of the device. The Honeywell HCM350B has a handy QuietCare Performance setting that minimizes the annoying drone often associated with humidifiers.
With this device, the antimicrobial design is the real selling point. Unlike many humidifiers, the Honeywell HCM350B uses a wicking filter to remove impurities such as germs, bacteria, and mold from the water it dispenses. The tank holds enough water for up to a full day of use between refills, too, and uses a wide opening for easy, spill-free refilling. Despite its antimicrobial design, you’ll still want to regularly and thoroughly clean it. The water tray and reservoir are dishwasher safe, making maintenance much easier than a lot of the competition.
While its matte-black finish and gentle contours represent nice design touches, the Honeywell HCM350B is still rather cumbersome for a unit not suited to humidify your entire home. If you need a humidifier for the whole house, we’d recommend shelling out a few extra bucks for a more powerful unit.

TaoTronics Ultrasonic Humidifier for Babies
While this might not be the most attractive TaoTronics humidifier on the market, the features are top-notch. The nano-coasted unit produces less than 27 decibels of sound and doesn’t produce any bright light, so it won’t disturb you while you sleep.
The 4-liter tank allows the unit to run for between 12 and 50 hours, but the humidifier is not overly large. The humidifier will also shut off automatically when the tank is depleted. It has a 360-degree nozzle, so you can choose exactly where you want the mist to go. You can even adjust the mist output between 60 and 300 ml per hour using the dial.
Cleaning the unit is easy, as the nozzle is removable. Plus, there’s a dust-proof sponge to prevent dust particles from entering the unit’s base.

Aircare MA1201 Evaporative Humidifier
The AirCare MA1202 is the no-frills, all-business humidifier on our list. The device isn’t going to take home any design awards, but when it comes to efficiently humidifying the air in your entire home, the AirCare Ma1201 is our utilitarian choice.
This device offers humidity control for 3,600-square-foot homes, and a set of wheels lining the bottom allows you to move the unit around with ease. A digital readout on the top of the device incorporates refill and “check filter” indicators, too, helping to eliminate any operational guesswork. The 4-gallon tank humidifies your environment for up to 36 hours. This particular humidifier also adds moisture to the air by circulating dry air through a saturated wick filter. As a bonus, this filter also traps mineral deposits.
Let’s be frank, the AirCare MA1201 looks better suited for an infirmary than a living room. For the price, however, there are few units capable of humidifying your entire house without daily refills.
