Top 7 Ultrasonic Humidifiers Review 2020
If you are on the market for one of these gadgets, you need to consider water tank capacity, total area the device will humidify, how long it runs alongside a few other extra features. This makes for an informed selection that you are less likely to regret. However, the amount of time you need to spend looking into each option is significantly reduced since we already researched manufacturer websites as well as took into account previous buyer experiences and product reviews. Consequently, you only need to read through the table, in-depth product descriptions, and lastly, the buying guide before selecting the best ultrasonic humidifier from the options provided.
PowerPure 5000 – Editor’s Choice

- Capacity: 3 gallons
- Coverage area: 700 sq. ft.
- Runtime: 12 hours (max.operation)
Other features: near-silent operation, a permanent ceramic filter, auto shut-off, LCD control panel, 12-hour timer function, safety lock, remote control included
This device comes with a minimalistic design and is also very quiet in operation. As such, placing this tool in your bedroom shouldn’t be too much of a hassle. While the machine is portable, it does need to be close to a power supply, such as a socket, to carry out its mandate. Nevertheless, the tank is significantly large, with a capacity of up to 3 gallons when full. This tank is as well easy to monitor from the outside to see if you are nearing on empty. Also, this component features a safety lock to prevent children from removing the water tank on a whim.
You are also likely to appreciate the permanent ceramic filter. Given that regular water may contain allergens and other harmful materials, the filter is there to ensure that the air you breathe remains pristine. However, even with the inclusion of a filter you need to clean the device regularly so that mold doesn’t build up inside. As well you would do well to use filtered water for a cleaner, fresher experience.
Another positive you can expect by buying this device is its extensive area coverage. It can service the humidity needs of the 700 sq. ft. around it and thus should be able to cover the length and width of most household rooms. Nevertheless, if you want to service multiple rooms at the same time, you may need to buy extra units.
Additionally, the device can emit both cool and warm mist. The latter is ideal for when the temperatures are low in the room and the general vicinity. You can turn it on or off and generally tweak any of the devices’ functionalities either by using the LCD control panel or the included remote. Another positive that you might like is the auto-shutoff feature when the tank nears empty.
The last thing to note is, of course, the one-year warranty just in case you run into any issues.

Of course, all this depends on the time of day and conditions available when you decide to use the device. You don’t need it at full blast in the morning.

In addition to the high mist and low mist modes that you will use during the day, there is the addition of night mode as well. The device itself has a polished outlook.

Here is yet another cool mist, only ultrasonic humidifier. From the outlook, the device has a rather aesthetically pleasing design and will be able to cover a 600 sq. ft. total area. As such, it is ideal for large rooms as well.
Nevertheless, the capacity is not too impressive maxing out at only 1 gallon. Eight hours is the device’s maximum runtime on full power. If you take it down to minimum mist output, this period can be extended to 24 hours.

The best ultrasonic humidifier will help keep your skin moisturized, alleviate cold symptoms, and even help you sleep better depending on the use scenario. However, spending money on a product that you don’t know about may leave you disappointed in its capabilities. You should be aware of the budget range to expect, features, and also, you should have at least three top picks to choose from. This way, it won’t matter if your first choice is not available. These are the reasons why the buying guide below is provided.
Advantages of ultrasonic humidifiers
As mentioned before, they help keep the humidity levels in the air at an acceptable level. Also, they help you breathe more comfortably as well as keep your skin from drying out. As such, if you experience low humidity in your office or household at any time of day, then an ultrasonic humidifier will make life remarkably easier on you.
Features to consider when choosing an ultrasonic humidifier
Each element on an ultrasonic humidifier will come with its advantages and disadvantages. Also, some features are more important than others; hence carry more weight when it comes to determining which model to pick. As such, a bit of knowledge on the features themselves may come in handy when you are making the selection; hence why they are highlighted below.
Even in low humidity areas, there are times when the weather is cold.
Runtime and capacity
The capacity refers to the size of the water tank since these devices need the fluid to function. An example is given in the Miro NR07G that has a one-gallon water tank. Also, if you look carefully through the device options we have provided above, you will notice a bit of correlation between the reservoir capacity and the runtime. Most of these devices will run until there is no water left; thus, those with larger tanks seem to run longer. However, there are exceptions to this rule. Additionally, you would be wise to get a purchase that also has a timer. As a consequence, you will not have to worry about shutting the device off and conserving energy as long as you set the timer.
This area refers to the distance that the humidity released by the device covers. As such, devices that cover areas of up to 250 sq. ft. are ideal for small room installations. Those devices that cover from 400 sq. ft. and upwards are for medium-sized rooms. As well there are those suited for the larger rooms, and these will have a square foot coverage of between 600 and 700 sq. ft.
Of course, with the above being the key features, others are presented in the device to sweeten the deal. Among them is a humidistat. The inclusion of this component in the overall setup of the equipment could be hugely beneficial to the user. Since the device will be able to regulate itself based on readings from the atmosphere, there is little for the owner to do but turn it on and off at specific times in the day. They might also have to refill the reservoir from time to time.
Also, some devices might incorporate components that allow for scents to be incorporated into the mist provided, therefore working as an air freshener for the room in question. Additionally, some devices like the Miroco Ultrasonic Cool Mist Humidifier may go the extra mile, even providing you with a warning whenever the water goes below a certain level.
Some people believe that ultrasonic humidifiers are, in fact, better than their evaporative counterparts. They do host some benefits over the latter with examples like the fact that they consume less energy, and they are quieter in operation. They are also compact to the point where they are easy to carry. However, evaporative gadgets also have top attributes, as well.
Most ultrasonic humidifiers do not kill germs. However, some of them do make it impossible for micro-organisms to live in their reservoirs. Even so, you would be better served by using purified water for your humidification needs. This is regardless of whether the device incorporates a water filter or not.
There are no health risks directly associated with using an ultrasonic humidifier. However, the water you use may pose several health risks. If mold and mildew are present in the tank, then they will likely be present in the mist produced and subsequently in the air you breathe. As such, this may result in allergic reactions. To be safe, you should clean the device regularly with clean water and again use purified water for humidification.
Just as we mentioned before, we already have a favorite in the PowerPure 5000. As such, we would order that as the first option from Amazon if we were in your shoes. The device has the most extensive area coverage of any device we have reviewed, not to mention remote control so you can operate it from anywhere within the room.
Nonetheless, things always go your way and so we have a contingency selection. This is the Pure Enrichment HumeXL. You may discount this device since it covers a relatively small area, but there are positive attributes to this device that you won’t find in a few other options. The most notable is the fact that you can switch from cold to warm mist at a moment’s notice. Apart from the editor’s choice, no other device offers the same. The PureGuardian H4750AR, as well, strikes our fancy due to the large water reservoir capacity that supports the elongated runtime.
It is as well hard to go wrong with any of the four remaining options. After all, you know best what your needs are and what product is best to service them.
