Are allergies, congestion, or chapped lips making sleep hard to come by? You may need a humidifier. During the cold winter months, moisture gets sucked out of our indoor air, creating a dry environment that’s uncomfortable to sleep in.
Humidifiers help rebalance the levels of moisture in your home, so you can sleep easier at night and breathe better during the day.
Today’s humidifiers all provide the basic functionality, but many offer additional features like a nightlight or timer. Depending on the features, brand, and model you choose, bedroom humidifiers cost between $25 to $150.
Check out our reviews and read our buyer’s guide to recognize the features you need and make the best humidifier purchase for your home.
As an ultrasonic humidifier, the Pure Enrichment MistAire humidifier promises “whisper-quiet operation.” Plus, the unit has a modern design, appealing to those who want their humidifier to be more like eye candy instead of an eyesore.
The MistAire humidifier reservoir is the ideal size for humidifying most bedrooms, while still being easy to fill by hand. With two output settings, users can choose the best one for their needs. The low setting operates for a full 16 hours, which is more than sufficient for the average night’s sleep.
The automatic shut-off ensures safe use, turning the machine off whenever the water level gets too low or the reservoir is removed. The nightlight can calm nervous sleepers or children, or never be used for those who prefer total darkness while they sleep. The MistAire comes with a disk cleaning brush, and all the individual parts are easy to disassemble and clean.
The MistAire includes all the features you want in a humidifier—and more—for an affordable price. That’s why we’ve made it our top pick.
The Honeywell HCM350B’s UV technology kills 99.9% of bacteria. As you pour tap water in, it filters through a UV water tank before passing over the wick and back into the bedroom air. This extra, germ-killing step makes this humidifier a favorite among sleepers with allergies or asthma. And, since all parts are dishwasher-safe, daily cleaning is a pain-free process.
The 1-gallon tank is easy to fill in the kitchen sink, but large enough to run for a full 24 hours, making the Honeywell HCM350B a great fit for anyone who wants to maintain constant humidity levels in their bedroom.
As a cool mist humidifier, it’s safe to use in children’s rooms. The Honeywell HCM350B is available in both black and white, so you can choose a design that matches the rest of your bedroom decor. The three-year warranty is longer than most humidifiers, boding well for the unit’s longevity.
While the Vicks Warm Mist Humidifier can be used anytime of year, it’s a favorite during cold and flu season thanks to its comforting warm vapor. With two output settings, you can quickly adjust the mist level to your needs using a dial on the side.
This humidifier is designed to help you sleep better, even when you’re congested. Simply add Vicks VapoSteam to the included Medicine Cup to create a medicated mist that relieves congestion while humidifying your bedroom.
A fully-translucent tank makes it easy to see at a glance whether the humidifier needs a refill. The Vicks Warm Mist humidifier automatically shuts off when the reservoir is empty, preventing overheating. The humidifier also includes a nightlight.
The Vicks humidifier costs less than $40, and since it’s filter-free, you don’t have to worry about replacement costs adding up.
If you want a one-and-done setup, the AirCare MA1201 is for you. This whole-house humidifier efficiently humidifies up to 3,600 square feet. The humidifier runs for up to 36-hours, so you can set it and forget it, too.
Despite its large coverage area, the AirCare MA1201 isn’t huge. It’s less than 2 feet tall and can be rolled around easily on wheels.
With 4 fan speeds, users have a wide range to choose from. The unit also includes a humidistat, so you can monitor the humidity levels in your home without having to buy a separate humidity meter. The automatic shut-off feature turns the unit off whenever the present humidity level is reached, or if the water tank is empty.
If you have multiple bedrooms which need humidifying, the AirCare MA1201 is a much more affordable option than purchasing multiple humidifiers for each room.
As a cool-mist humidifier, the Crane Ultrasonic is safe for use around children, but there are other reasons why we selected it for our top nursery pick.
The Crane Ultrasonic humidifier enables easy breathing and congestion relief for your baby. It effectively cleans the air in your baby’s room, thanks to its clean control antimicrobial base. This humidifier is also a better fit for nurseries and children’s rooms, due to its smaller coverage area of up to 500 square feet.
The Crane Ultrasonic also comes in 8 color combinations, so you’re sure to find one that fits right in with the rest of the nursery decor. The teardrop shape is also very cute.
This humidifier promises energy-efficient and quiet operation for up to 24 hours, and it automatically turns off whenever the water tank is empty. As a filter-free humidifier, you don’t have to worry about buying replacement filters.
The TaoTronics Cool Mist Humidifier is a great choice for users who want like to geek out on technical bells and whistles.
This ultrasonic humidifier includes a LED display that monitors the indoor humidity levels and a 360-degree mist nozzle that can be rotated to angle the mist just right while you sleep. There’s also a built-in timer and sleep mode. The timer works from 1 to 24 hours, and operates on 3 mist settings.
The TaoTronics humidifier works in rooms up to 538 square feet, and produces less than 38 decibels of noise, making for whisper-quiet operation. It includes a cleaning brush and filter, and additional replacement filters are about $8 each.
Aromatherapy practitioners love the VicTsing because they can enjoy a humidifier and diffuser in one unit. The wood grain finish and 7 LED nightlight options provide a nice ambience, too.
Even if you’re not into essential oils, the small size of the VicTsing (it’s just 6″ high) makes it a perfect travel companion for whenever you need to take your humidifier on the go. However, that small size makes it a better fit for nurseries or smaller bedrooms.
The VicTsing comes with 4 time options and two mist settings. The 10-hour operation applies to the lowest mist setting, though, so this is not a good fit for those who need high humidity over an extended period of time.
The VicTsing is a diffuser first and a humidifier second, but it’s a solid option for travelers who need a portable option, as well as anyone who uses essential oils to help them sleep.
Bedrooms with stale, dry air can negatively affect sleep quality and duration. Other drawbacks include a higher risk of allergies, dry skin, and chronic congestion. Climate is a major factor related to air quality; different regions of the U.S. are susceptible to extremely high and/or extremely low temperatures that dry out indoor air.
Humidifiers, which utilize cool or warm mist to refresh interior air, can be very beneficial for sleepers experiencing uncomfortable conditions related to air quality. However, due to the wide range of humidifier models available, selecting the best one for your bedroom can be a challenging process.
This guide includes an overview of common humidifier types and features, cleaning and care instructions, some notable health benefits, and key factors for humidifier buyers. Read on to learn more.
Though there are many subcategories for humidifiers, the majority of models sold today are one of two main types:
Though specs vary by individual models, most warm-mist and cool-mist humidifiers come with the following features:
When browsing different humidifier models, shoppers can use these specs and features to determining which product is best for them. Important considerations include:
Shoppers should consider their bedroom size when choosing a humidifier based on its strength. Though ideal for larger spaces, powerful humidifiers can be overwhelming – and excessively loud – for those with smaller sleeping quarters.
Alternatively, those with larger bedrooms should opt for a stronger humidifier, since most low-output models will not improve the air quality to a noticeable extent.
The capacity of a humidifier reservoir may fall anywhere between 300 mL and 4 gallons. While 1-gallon or larger reservoirs are recommended for mid- and large-size bedrooms, they may be overkill for smaller sleeping quarters.
Also keep in mind that water capacity is linked to the humidifier’s runtime. The larger the tank, the longer the humidifier will release steam or mist before the device automatically shuts off.
Though humidifiers are designed to be compact and fit into most bedrooms, shoppers should measure their space to ensure the device will fit in its intended area. Measuring areas in the sink is also recommended to ensure the reservoir can be completely filled.
Additionally, buyers should check the humidifier total weight, since they will ostensibly be carrying the device to the sink on a regular basis in order to refill the reservoir.
Humidifiers are designed to humidify a certain size area. Generally speaking, warm-mist humidifiers have smaller coverage areas than cool-mist humidifiers. The smallest humidifiers are intended for desktop use, while the largest ones can add moisture to an entire house.
Humidifiers for bedrooms fall somewhere in the middle. Over-humidification can lead to mold and other air-quality issues, so finding a model with the optimal coverage area is highly recommended.
All humidifiers produce some sort of noise, though ultrasonic models tend to be the quietest while evaporative and warm-mist humidifiers are usually the loudest. That being said, the noise is not necessarily disruptive and may serve as white noise that helps with sleep onset.
Typically, larger humidifiers are louder than smaller models. Higher speed settings may make more noise than quieter settings, as well.
Recommended cleaning and care procedures vary by model. Some require daily maintenance while others only need to be cleaned and cared for once a week. Check the owner’s manuals to learn more details. Our ‘Caring for a Humidifier’ section below also has additional information.
Humidifiers are generally inexpensive, with most warm-mist and cool-mist models available for $100 or less, though some cost as much as $200. Larger models cost more than smaller ones; likewise, humidifiers with more advanced features and settings will probably have higher price-points than their more basic counterparts.
Most humidifiers can cut costs on the owner’s utility bills. However, some models – namely ultrasonic humidifiers – are more conservative with energy use than others.
Using a humidifier to cleanse air and improve air quality carries a host of benefits for sleepers, particularly those who live in extreme climates. These include:
Though humidifiers offer health benefits, owners should also consider the following variables related to safety and human health.
While clean, properly functioning humidifiers can improve bedroom air quality, dirty humidifiers often have the opposite effect. Here are some general guidelines to follow to ensure the humidifier is clean and cared for properly.
Before purchasing a humidifier, shoppers should take the following factors into account:
