After conducting 50 hours of research and analysis to determine which humidifier available now is the best on the market we found that the Pure Enrichment Ultrasonic Cool Mist Humidifying Unit is the clear top pick for just about every room. From its adjustable settings to its easy-to-clean design, this humidifier stands out amongst the many other models for its quality and functionality. It’s very affordable and out-performs many of the more expensive models.
The Pure Enrichment Ultrasonic Cool Mist Humidifying Unit uses ultrasonic technology to quickly and quietly raise the humidity level in medium-sized rooms. It’s easy to use, to fill, and to clean making it a very convenient option. This model also features a large tank which allows it to run for long periods of time without needing to be refilled and has adjustable settings so you can customize how much mist it produces.
Close behind our top pick, the Homasy 800ml Ultrasonic Cool Mist Humidifer proved to be another fantastic option. This model is not only a humidifier but can also be used as an essential oil diffuser to add scent to your home. It’s great for small- or medium-sized rooms and its large tank ensures it’ll run for hours. It’s a great unit with an attractive design that should be considered if you’re in the market for a humidifier.
Our step-up pick is the SPT SU-4010G Dual Mist Humidifier with ION Exchange Filter which offers some extra features. This humidifier can be used effectively in substantially larger rooms than our top pick and can produce cool or warm mist. While this unit does include some of the same standard features as other models on this list, it comes with a couple additional ones—including a split nozzle and more strength settings—that make it more adaptable to your needs.
For those on a budget, we recommend the PureGuardian H900P 10-Hour Nursery Cool Mist Humidifier. Though smaller than the other models listed, this unit can run through the night and is capable of an output similar to that of our top and runner-up picks. Because of this unit’s size, it works best in smaller spaces but can be used to improve humidity in medium-sized rooms as well. The name suggests it’s for kids but this unit’s great performance makes it perfect for anyone on a budget.

Why you should trust us
We have an extensive background in product research and put our analytical skills to work when looking at humidifiers. Dozens of hours were spent investigating and we took our time finding out exactly what each model has to offer and how they perform in real homes. Between the many reported tests and the firsthand user experiences we were able to make a list of the best humidifiers on the market.
Who should buy this?
Humidifiers are fantastic for people whose homes are very dry. If the air is causing irritation—such as dry eyes, skin, or throat—a humidifier is a good investment to improve comfort. Some people also use humidifiers to help prevent the spread of germs and to soothe symptoms when colds or flus hit. Some humidifying units can also be used as diffusers, so if you’d like to improve the humidity level in your home and add a pleasant scent to the air, a humidifier is a great purchase.
Types of humidifiers
There are three main types of humidifying units: ultrasonic, evaporative, or steam-based.
Ultrasonic units are often the least expensive option but quite effective. These use vibrating plates to turn the water in the tank into a fine mist which is then blown from the unit by a fan. This mechanism is very quiet and some models are nearly silent. This mechanism has the potential to produce a white dust but many models today do not have this problem.
Evaporative units also have a fan mechanism which is used to blow the water in the reservoir and expel the mist created. This type is also very quiet, hygienic, and does not create any white dust. Both the ultrasonic and evaporative mechanisms create cool mist.
Steam-based humidifiers create a warm mist by heating the water in the tank. These are great for killing germs to create a very hygienic must but they tend to get more build-up and require more frequent cleaning.
Humidifiers also sometimes come with the description of portable, console, or diffuser. Most of the models on our list are considered portable as they are easy to move and not especially heavy. Console units are quite a bit larger and heavier and not meant to be moved around a lot. They are also usually more powerful. Humidifiers that are considered diffusers are meant to be used with essential oils and are great for spreading scent but aren’t usually as effective at raising humidity.
How we picked
To determine which humidifiers are best, we looked at what kinds of features the models had and how well they function.
Quiet operation is a basic quality that is important. Since humidifiers are often used in nurseries or bedrooms through the night a noisy unit can be very disruptive. Humidifiers reviewed as being nearly silent were more seriously considered. Another basic that we looked for is an automatic shut-off function. This is not on all units but is a valuable safety feature.
Tank size and runtime were also big considerations. A larger tank typically means a longer runtime and fewer refills which is convenient for the user, especially when used overnight. The output of the unit can be calculated using these numbers and this was also considered when using models. Some small units only put out 15ml of mist per hour while larger ones can produce over 300ml per hour. Humidifiers with higher output capabilities were considered preferable but mid-range were satisfactory as well.
Most units are built to work in a particular sized room and the maximum size is typically listed on the package or product page. Having the capability to humidify a larger space is great but since most rooms people use these units in are medium sized, these were considered similarly.
Multiple settings were another factor as customization is great for any appliance. Bonus features and lots of different settings were not necessary to be considered for our list but those with multiple settings took precedence over those with a simple on/off function.
General ease of use was also important. Those models that were reviewed as easy to operate, to fill, and to clean were placed higher on our list. There were many qualities to consider and some models even had bonus features that could be beneficial, but if it wasn’t easy to use the humidifier wasn’t worth considering.
Finally, with all other aspects in mind, the feedback on performance from professionals and day-to-day users helped give a clear idea of how well the humidifiers actually work. Some models sound great on paper but when customers report multiple problems, it’s evident that the quality of the humidifier is questionable. Our list consists of units that have fantastic features and operate well.
Top Pick: Pure Enrichment Ultrasonic Cool Mist Humidifying Unit
From the dozens of models we looked at, the Pure Enrichment Ultrasonic Cool Mist Humidifying Unit is the one we would recommend for most buyers. This unit is sure to raise the humidity in any medium-sized room and is easy to operate and maintain.
Like most of the models on this list, the Pure Enrichment humidifier produces cool mist using ultrasonic technology. This makes the unit safe for use in bedrooms of young children as there is no risk of burns from hot water and it will not raise the temperature in the room which can be a downfall of warm mist in summer months. The ultrasonic mechanism is also remarkably quiet with many users saying the humidifier is virtually silent so it won’t disturb your sleep.
This model is ideal for medium-sized rooms like offices, bedrooms, and nurseries and can be very effective in small spaces as well. It’s built with a large reservoir to hold up to 1.5 litres of water allowing it to run up to 16 hours on low or 12 hours on high. This equates to an output of about 90 to 125ml per hour which will raise the humidity in the air efficiently and keep the air moisturized through the night. When the water does run out the machine turns off automatically.
Many humidifiers run at just one speed but this particular model is designed with two options—high or low—offering the user a bit of flexibility in the amount of mist produced. The direction of the mist can also be changed without rearranging the unit itself by simply turning the 360° nozzle to point in the preferred direction. Another bonus feature is the nightlight which is great for kids and can be turned off when not needed.
The Pure Enrichment humidifier is also very convenient to clean as the pieces come apart easily and there is no filter to replace. These are important things to consider when purchasing a humidifier since regular cleaning is required to ensure the water used to create the mist remains free of bacteria, mold, and fungi and the cost of filters can really add up.
On top of all the great qualities of the machine, this model also comes with a 2 year warranty which is much longer than what is offered with most models (if there is a warranty at all). If your humidifier arrives damaged or malfunctioning or if anything happens in the first two years the company will replace the unit for a new one.
Flaws but not dealbreakers
One thing is the frequency of cleaning. You might be disappointed with the regular cleaning required by the unit. However, this isn’t really a flaw with this unit and is simply part of maintaining a humidifier. Experts recommend rinsing humidifying units every day and thoroughly cleaning at least once per week when used daily.
Runner-up: Homasy 800ml Ultrasonic Cool Mist Humidifier
The Homasy 800ml Ultrasonic Cool Mist Humidifer is another great model that we would recommend right behind the Pure Enrichment humidifier.
This humidifier holds up to 800ml of water which is quite a bit less than our top pick. However, it is able to run steadily for 10 hours and has an output of 80ml per hour which is sufficient for raising the humidity in a room without creating excess moisture. The Homasy unit is great for smaller rooms up to 161 square feet but can also be helpful in medium rooms as well.
There is a single touch button on the front of the unit used for controlling the humidifier making it very simple to operate. However, there is only one setting which may be a downside for those who like being able to adjust the amount of mist produced. The top of the machine has a small spout that can be rotated 360° to direct the vapor in any direction. The Homasy humidifier does not have a timer but does automatically shut off when the water is depleted.
Along with easy operation, the Homasy humidifier is easy to fill and clean. The top of the unit lifts off for filling and the smooth design means it’s easy to reach every part when cleaning it out. As mentioned previously, humidifiers need regular cleaning so this is a definite bonus. Other bonus features include the nightlight function which creates a soft blue glow and the unit’s ability to act as an essential oil diffuser while humidifying the air.
Step-up pick: SPT SU-4010G Dual Mist Humidifier with ION Exchange Filter
If you’re looking for a humidifier that offers more customization, go for the SPT SU-4010G Dual Mist Humidifier with ION Exchange Filter.
Like the top and runner-up picks, this humidifier is an ultrasonic unit so it’s quite quiet which is great for use through the night. However, some of the other specifications are a bit more advanced. The tank on this model holds up to 4 litres of water and creates an output of 400 ml per hour that can humidify rooms up to 500 square feet. This output is much higher than the two previously mentioned models so it’s great for very dry climates. With the tank size and output considered, the total runtime works out to be approximately 10 hours on one tank, but reviewers say it will run up to 12 hours on the high setting.
Another great thing about this unit is that it can be set to produce either warm or cool mist. There are times when one is preferred over the other so it’s nice to get both options in one machine. The amount of mist can also be customized using a simple knob adjustment on the front of the machine. For directing the mist, this humidifier has dual 360° nozzles which can be pointed in one direction or two different directions to ensure the mist is dispersed throughout the room. Overall, the SPT humidifier has a lot of potential when it comes to customizing how you humidify your space.
The easy cleaning is another great aspect of this humidifier. The shape of the tank and the wide tube for the spout makes it easy to reach every part that needs to be cleaned. It’s also interesting to note that many users remarked that the unit doesn’t produce much build-up which makes the cleaning even easier. The SPT humidifier uses disposable filters and replacements cost just a little. This recurring cost should be considered when choosing a humidifier as a new filter will be needed every 3 months to a year depending on what type of water you use in the machine.
Budget pick: PureGuardian H900P 10-Hour Nursery Cool Mist Humidifier
There a lot of lower-priced humidifiers available but there are few rated as well as the PureGuardian H900P 10-Hour Nursery Cool Mist Humidifier. Despite the name, this model is not just for nurseries but great for bedrooms, offices, and other small rooms as well.
The PureGuardian humidifier uses ultrasonic technology to quietly produce a steady stream of cool mist. The reservoir is built to hold 800ml of water and claims to run for 10 hours on the low setting. However, users have stated that, on average, the unit runs for about 8 hours on the low setting and up to 6 on high. With these numbers, unit’s output is calculated to be between 80 and 150ml per hour making it as capable as our top and runner-up picks when it comes to adding moisture to the air.
Though small, this humidifier has a number of great features. It has an auto-off function that turns off the humidifier when water runs out and multi-colour nightlight that is perfect for use in children’s rooms. This PureGuardian model can also be used as a diffuser. On top of the unit, there is a small white tab where essential oils or medicine can be placed to be spread throughout the room with the mist.
Cleaning this model is quite simple. Using the brush included with unit and some vinegar, it’s very easy to give the tank and machine a thorough clean. This particular humidifier doesn’t tend to get a lot of grime thanks to the built-in Silver Clean Protection which prevents the growth of mold and mildew on the humidifier’s surfaces. Easy to run and easy to maintain, this small humidifier has a lot to offer.
Most stylish humidifier: Amir Cool Mist Ultrasonic Humidifier
If having a humidifier that looks great in your room is a priority, check out the Amir Cool Mist Ultrasonic Humidifier. It’s an effective machine with a 300ml reservoir that can produce mist for up to 10 hours on low or 6 hours on high which equates to an output of about 30 to 50ml per hour. It has two settings for mist strength, four timer options, and an automatic shut-off feature to ensure it doesn’t continue running when the water runs out. It’s also designed to be an essential oil diffuser to spread your favourite scent throughout your home. It functions very well, but it’s the look that earned it a spot on this list. The smooth, round shape of the machine is very aesthetically pleasing and the woodgrain look gives it a modern, decorative look. It also has a 7-colour LED light that creates a beautiful glow. This model won’t raise the humidity as much as a larger unit but it will add a bit of moisture to the air and look stylish doing it.
Best travel humidifier: JZK Blue Mini Portable Night Light Air Humidifier
The JZK Blue Mini Portable Night Light Air Humidifier is a well-rated and effective little unit that costs just a little. Small enough to sit in the palm of your hand, its reservoir holds just 120ml which produces mist for to up to 3 hours. This is not especially useful in larger rooms, but is perfect for sitting on your desk while at work since it can be plugged into a wall outlet or a USB port. Its USB cord and miniature size also make it perfect for use in the car during dry winter months. We wouldn’t recommend relying on this model to raise the humidity in your bedroom, but it’s a fantastic option if you want to take your humidifier with you on the go.
Best anti-microbial humidifier: Honeywell Germ Free Cool Mist Humidifier HCM-350
There is always the possibility of harmful build-up inside humidifiers and that’s why keeping them clean is so important. However, some models are built with extra features to ensure that the water being expelled as mist is as pure as possible. Of the anti-microbial units we looked at, the Honeywell Germ Free Cool Mist Humidifier HCM-350 came out on top. Its 1.5 gallon tank can be run for up to 24 hours and works in small- and medium-sized rooms. It’s quite easy to control using the dial on top of the unit and it comes apart for cleaning. This model does use a filter that will need to be replaced periodically and they cost very little. Its reliable functionality is combined with germ-fighting technology to kill up to 99% of bacteria, mold, fungi, and viruses for the purest mist possible. For those concerned about the cleanliness of their humidifier’s output, this Honeywell model is the best option.
Best for large spaces: Honeywell Cool Moisture Console Humidifier
Though our step-up pick, the SPT SU-4010G Dual Mist Humidifier with ION Exchange Filtercan manage rooms as large as 500 square feet, the Honeywell Cool Moisture Console Humidifier is a multi-room humidifier capable of humidifying spaces up to 1900 square feet. This model is more heavy-duty than the others on this list and that comes with some downsides, namely that it is not as quiet as the smaller models. It runs at about 55 decibels which is comparable to an air conditioner which runs at around 60 decibels. It’s also quite a bit larger than the other units; measuring approximately 17.5″ x 23″ x 15″ and weighing 20 pounds, it’s not meant to be placed on a desk or bedside table. It’s a powerful machine that can run for 24 hours on a single fill but it uses less energy than an 80 watt light bulb. If you’re just looking to raise the humidity of a larger room our step-up pick is likely sufficient, but for multiple rooms or very large spaces this console humidifier is the way to go.
There are some models that we’d like to mention that didn’t fit into any other area on this list. The first is the TaoTronics TT-AH002 Ultrasonic Humidifier with Cool Mist. It’s comparable to our runner-up pick in terms of settings but has a higher hourly mist output. Its large reservoir holds 3.5 litres and can produce about 350ml of mist per hour for up to 10 hours. It’s a very quiet machine that has an extra fine ceramic filter to help remove bacteria and odor from the water in the tank making it fantastic for babies as well as older children and adults. The TaoTronics model should be considered if you need a higher output.
Another humidifier worth considering is the Seneo 3.0L Cool Mist Humidifier. It functions beautifully for up to 33 hours on the weak level and has a built in sensor that can detect the humidity in the room and adjust its output accordingly. Users agree that it’s worth the price for an effective humidifying unit that can determine the appropriate amount of mist necessary on its own.
The Vicks Warm Mist Humidifier is a model that is remarkably popular and it’s quite affordable. With 2 settings, automatic shut-off, the ability to operate for up to 12 hours on one fill, and a medicine cup feature, it’s understandable that this humidifier is frequently selected for top 10 humidifier articles.
Wrapping it up
We recommend the fantastic Pure Enrichment Ultrasonic Cool Mist Humidifying Unit as the best humidifier for most homes with the Homasy 800ml Ultrasonic Cool Mist Humidifer as a second consideration. If you’re looking for a unit with more features and settings, the SPT SU-4010G Dual Mist Humidifier with ION Exchange Filter is a versatile unit that operates smoothly. For those on a budget, we recommend the PureGuardian H900P 10-Hour Nursery Cool Mist Humidifier as a high-functioning unit at an affordable price.
