Best for Large Spaces

The Air Innovations MH-701B isn’t just elegant and attractive; it is highly effective and functional too. It is a powerful ultrasonic humidifier with a run time of up to 96 hours and has a huge 1.7-gallon water tank built into its compact body.

Other noteworthy features include a ceramic filter for cleaner mist and an aroma tray to use as a diffuser. Plus, it comes in a variety of colors to choose from.




Our Review

This Air Innovations humidifier is eye-catching and features a round bottom with curved edges. The sides deepen in and then spread out to form the top side, which is characterized by a lot of curves. The top is finished off with a silver edge that adds further elegance to its look.

On the front of the humidifier is a circular LED control panel with different options to adjust its settings. The panel includes an easy on/off button and a mist button that lets you choose between 5 different mist settings: low, medium, high, supreme, and turbo.

Most devices offer only 2 or 3 mist levels, but the Air Innovations MH-701B goes a bit farther than that.

Apart from that, the humidistat button lets you select the desired humidity levels for the humidifier to automatically operate on. Meanwhile, the delay start option allows you to program the dehumidifier to automatically turn it on whenever needed.

It also has a waterless indicator for when the tank is empty and a Beep/Dim button that silences its beep and dims the LED display.

It is a big device, but that’s not surprising given the large 1.7-gallon water tank. This is a bottom-fill dehumidifier, and one complete fill is enough to last up to 96 hours on low speed. It is suitable for large rooms, small apartments, or any other area of up to 600 square feet.

Although the device itself is quite tall, it also comes with a 15-inch tall nozzle extension. This allows you to use it either as a tabletop humidifier or place it on the ground as a floor unit.

It also has a handle on the top of the tank, which makes it easy to carry.

The MH-701B also features a ceramic filter and an aroma tray. It rehydrates your skin, treats itchy eyes, and moistens the dry nose and nasal pathways to provide immense relief.

Best for Medium Spaces

The MH-408 has variable mist output levels, with a run time of up to 70 hours on the low setting. Equipped with a large 1.1-gallon tank, it can easily humidify spacious rooms.

It has a clean and small design and features a 360° rotation mist nozzle to target specific areas. Meanwhile, the analog dial lets you set the mist intensity you are comfortable with.




Our Review

The MH-408 is best for medium-sized spaces. It features a 1.1-gallon water tank that allows the humidifier to run continuously for up to 70 hours on low mist output. This means you can use it for almost 8 nights of sleep on a full tank before you need to fill it up again.

Although it may initially seem like a pretty basic unit, it definitely is not. While it lacks fancy features like a digital display and digital humidistat, it has some other ones to make up for it.

For instance, it has a 360° rotating mist nozzle that lets you set it in whichever direction you want the mist to blow. It also has a top-fill design that is simple and easy to fill up. Meanwhile, a built-in grip on the tank makes lifting it easy, even when it is full of water.

It has a manual dial for turning it on and regulating the mist output. You can choose between 3 variable speeds: low, medium, and high. But there are other variable levels in between, too, so you have more options than what actually meets the eye.

In addition, an indicator light flashes green when the operation is normal and turns red when it runs out of water. And the automatic shut-off safety feature switches off the unit when the tank is empty.

Best for Small Spaces

Although the Air Innovations AI-100 is a personal humidifier, it is suitable for humidifying small spaces too.

It features a small, spherical design with a built-in color-changing mood light. Although its water capacity is small, it is still good for up to 12 hours of misting. You can power it up with a traditional power adapter or hook it up with a laptop, PC, or even a power bank.  




Our Review

The Air Innovations AI-100 produces a powerful, fine, cool mist that’s quickly absorbed and inhaled. This little guy packs a punch of performance inside its compact body. It is the longest-running Air Innovations personal humidifier, boasting a run time of up to 12 hours on a single fill.

The unit is pleasant to look at. It is spherical with a color-changing mood light glowing in its center. There are no complicated controls or dials to fiddle with. Instead, there are only two buttons: one to switch the unit on and the other for light.

It is available in 2 equally appealing color options: black and white.

This humidifier is perfect for taking with you while traveling. It is fairly small, so fitting it inside your luggage or handbag won’t be a problem.

It comes with a USB cable that works with a standard adapter, so you won’t be hard-pressed to power it up. You can also use your laptop or a power bank for this purpose.

Although there are no mist levels to choose from, the pre-set mist output is enough to cover areas up to 150 square feet. As a personal humidifier, you can set it by your side to ensure that the air you breathe is moist and comfortable.

Air Innovations Humidifier Buying Guide

About the Air Innovations Brand

Air Innovations is an old and trusted brand in the home comfort industry. Its products focus on enhancing your quality of life with clean air solutions. The Air Innovations product line-up consists of humidifiers, air purifiers, aromatherapy, diffuser humidifiers, and cooling fans.

The company was founded by Joe McDonnell, a well-known and respected innovator and entrepreneur. He worked as a successful TV spokesperson on shopping networks, inventor, and business entrepreneur for 30 years before finding the company.

Given his decades of experience in marketing and entrepreneurship, Joe McDonnell had immense knowledge of what appealed to the buyers.

As a result, Air Innovations products have consistently outperformed competitor units, making it a leader in providing clean, pure, and healthy moisture to rehydrate your skin and nasal passages and creating a comfortable indoor environment in your home and workplace.

Types of Air Innovations Humidifiers

The Air Innovations humidifier range consists of ultrasonic, cool mist, room, personal, top-fill, and aromatherapy humidifiers. They don’t manufacture whole-house humidifiers or evaporative and warm mist humidifiers.

Let’s take a closer look at each type.

Room Humidifiers

As the name suggests, Air Innovations room humidifiers are designed to humidify entire rooms. They are specially built with bigger water tanks to cater for the whole room.

With a higher mist output, they effectively release moisture into the air. The extra moisture quickly brings up the humidity level of the entire room, making everyone in it comfortable.

Air Innovations room humidifiers range from average of 1.2-gallon units to huge 2-gallon models with excellent run times. You can find units for medium, large, and extra-large rooms, so choosing a suitable one really depends upon the size of the room you want to use it in.

Personal Humidifiers

Air Innovations personal air humidifiers are designed to humidify the immediate space around you. They are small-capacity devices with a runtime of 2 to 12 hours.

Some of these models don’t even have a built-in water tank; instead, they rely on an external water supply to produce mist. Some models have adapters to screw in water bottles, while others are long, straw-shaped to dip in a glass or a bottle of water.

Aromatherapy Humidifiers

Aromatherapy humidifiers from Air Innovations create a relaxing ambiance and help improve your well-being. They work with a wide range of aromatics to provide you with lasting physiological and psychological comfort.

Some of these devices have built-in aromatherapy trays where you can place a special scented pad, while others allow you to add a few drops of your favorite essential oil to the water.

In both cases, the result is a heavily scented mist that makes the indoor space more comfortable and relaxing.

Cool Mist Humidifiers

air innovations humidifier review

Cool mist humidifiers by Air Innovations are designed such that their mist also generates a cooling effect. With one of these, you can create a cooler and more comfortable indoor atmosphere. In the summer months, these can keep you cool during the day and help you sleep better at night.

 Air Innovations cool mist humidifiers also vary in capacities from 1.1 gallons to 2.15 gallons. They can effectively fill medium to large-sized rooms with thick mist without using tons of energy.

Ultrasonic Humidifiers

Air Innovations ultrasonic humidifiers are ultra-quiet, without any fan noises as are common in evaporative humidifiers.

Air Innovations ultrasonic humidifiers generate high-frequency vibrations that break down water tension and create a fine mist that fills your room with much-needed moisture.

Top-Fill Humidifiers

As the name suggests, top-fill humidifiers are designed for great convenience. They are easy to fill under a sink or with a water pitcher and ensure ease of use.

Each new model introduced in this category comes with new and innovative ways of making refilling easier, thus ensuring convenience.

Why Air Innovations humidifiers over other brands?

Air Innovations’ range of products cuts across several industries, and their low manufacturing time has made them one of the top humidifier manufacturers in the world. So how exactly do their products stand out from the rest?

Here’s how:

Large tank Capacities

Air Innovations humidifiers are well-known for their large water tanks. Where other brands’ humidifiers have a maximum capacity of 1 gallon, most Air Innovations humidifiers only start from here.

Their range commonly includes 1.2-gallon, 1.6-gallon, and 1.7-gallon models. Some of their units have a maximum water tank capacity of 2 gallons – this is something you don’t find in humidifiers from many other brands.

Exceptionally long run times

Due to their large water tank, these humidifiers also tend to have an exceptionally long runtime.

Where many other humidifiers tend to run for over 24 hours on a single fill on the lowest setting, Air Innovations humidifiers last as long as 96 hours, depending on the model. So, you can use one of these for several nights before needing to refill the tank.

Antimicrobial materials

One thing that truly sets Air Innovations humidifiers apart from humidifiers by other brands is their antimicrobial construction.

These are designed such that harmful microbes like bacteria, mildew, and mold cannot grow on them even after regular contact with water and humid working conditions. This prevents cross-contamination and the spread of harmful diseases through its mist.

Digital control

air innovations personal humidifier

Another good thing about some Air Innovations humidifiers is their easy-to-operate digital control, so using them is as simple as pressing a button.

These models are engineered with a built-in humidistat. All you have to do is set your required humidity level into the device, and it will work automatically to achieve it. Once reached, the unit will cycle off, and when the humidity levels start dropping again, it will turn back on to regulate it.

Built-in aroma tray

Although Air Innovations has an entire category of aromatherapy humidifiers, most of their humidifiers have built-in aroma trays to use with scented pads. This eliminates the need to mix essential oils into the water tank.

As surprising as it might sound, this practice is quitewidespread, but some units are just not made for it, and doing so affects their functionality.

But with most Air Innovations humidifiers, all you have to do is insert the scented pad into its aroma tray and let your favorite scent wash over you.

Vast Color Choices

Each Air Innovations humidifier comes in a variety of colors and sometimes patterns to choose from. You’ll find their models available in traditional finishes of black and silver, but contemporary colors like red, blue, teal and a leopard pattern are also available.

Other brands do offer color choices, but they are not as vast as the ones you get with Air Innovations.

What to look for in an Air Innovations Humidifier

With so many types and models available, choosing one is a difficult task. But you can find a suitable model keeping the following in mind:

Room Size

When purchasing a humidifier, the first thing you should determine is whether it is suitable for your room size.

Now, Air Innovations humidifiers are available in different water tank capacities and coverage areas. The smallest of them is suitable for a room of up to 150 square feet, while the largest one boasts a vast coverage area of up to 700 square feet.

The key to finding the best humidifier is to know your room size and then choose a unit with a similar area coverage rating.

Run Time

Although Air Innovations humidifiers have long run times, it is still crucial that you choose a unit with a run time that suits your purpose.

For example, if you plan for nightly usage, the humidifier should at least run for 8 to 12 hours before the water runs out.

Depending on the water availability and how much time you are willing to spare in humidifier maintenance, make sure you purchase a product with sufficient run time.


Most Air Innovations humidifiers are fitted with a digital control panel and a built-in humidistat. The control panel is programmable and lets you choose between different settings. Some units even come with remote control. 

Meanwhile, some units have a manual dial as well, but digital controls are comparatively better, easier to operate and more accessible.

You should carefully check out the different control options Air Innovations offers and choose one that you are more comfortable with.

Timer Settings

Most Air Innovations humidifiers, especially those that have a long run time, come with a timer. You can use it to pre-set the number of hours you want the machine to run before automatically turning it off.

A timer comes in very handy in creating the right atmosphere before you get back home or before you wake up. It also ensures your energy bills are appropriately managed and prevent unwanted spikes.

Filter Types

Most ultrasonic humidifiers don’t make use of filters. However, Air Innovations ultrasonic humidifiers use ceramic filters. They are permanent filters that last a lifetime.

Some models use hard water filters, too, that significantly reduce the amount of white residual dust created when the machine is used with tap water.

Take your time to look at all the options and choose the unit that best meets your criteria.


Other brands offer a humidistat in their premium humidifiers, but Air Innovations includes a humidistat in many of its units, so users don’t have to face any difficulty while using the device.

A humidistat lets you set the desired humidity level range and produces mist until the level is reached. Then it cycles off but continues to monitor the relative humidity levels. Once the levels start to drop again, it turns back on automatically and starts working again to regulate humidity.

So, if you have the budget and the need, go for a unit with a built-in humidistat to help you regulate indoor humidity efficiently.

Pros and Cons

air innovations ultrasonic humidifier manual

While we do believe Air Innovations is one of the best humidifier brands, it comes with its fair share of limitations, too.


Attractive and Colorful Designs

The biggest perk of Air Innovations humidifiers is their attractive design and color choices. Their models are more vibrant than humidifiers from other brands, but that doesn’t mean there is a shortage of subtle colors in their range.

You can choose between a more contemporary-looking red or teal unit or go with a conventional white and gray device. The choices are plenty.

Feature-rich Machines

Air Innovations humidifiers are some of the most feature-rich machines.

They are powerful, ultra-quiet machines with large water tanks that offer good area coverage and long run times. Most have digital controls with a built-in humidistat for ease of operation, while some units even come with remote controls that improve the overall experience of using a humidifier.

Permanent Ceramic Filter

Where most ultrasonic humidifiers are not compatible with filters, Air Innovations incorporates specially-designed ceramic filters to trap impurities. You can simply clean them every once in a while, to enjoy cleaner and fresher air.

Antimicrobial Tanks

Since a humidifier is in constant contact with water, there is a high chance of harmful microorganisms like mold and bacteria growing inside them.

Air Innovations humidifiers are made with antimicrobial materials, so there is no chance of harmful microbes growing inside them.

No Shortage of Replacement parts

Another perk of investing in an Air Innovations humidifier is the easy availability of replacement parts.

If your Air Innovations humidifier starts malfunctioning at any point, you can also easily have it repaired.


Ultrasonic Humidifiers Only

The greatest limitation of Air Innovations humidifiers is that they only make ultrasonic humidifiers. They don’t have any evaporative or warm mist humidifiers in their range.

So if you want a warm mist to keep you cozy during winters, or a humidifier with some white noise, you will have to turn to another brand.

Distilled Water Only

As with any ultrasonic humidifier, Air Innovations humidifiers are the most effective when used with distilled water.

If you use tap water in these devices, its mineral content will leave behind a white residue in your machine. This white residue is often released out and settles down as whitish dust on every surface in the room.

Frequently Asked Questions

air innovations cool mist ultrasonic humidifier

Are humidifiers from Air Innovations free from harmful chemicals like BPA?

Yes, all the humidifiers from Air Innovations are free from harmful chemicals like BPA. They are thoughtfully designed to provide gentle humidity without diffusing toxic chemicals into the air. These are completely safe to use around children, especially babies.

Why is the tank empty indicator still on when I have refilled the tank?

This can happen when there is trapped air preventing the water from flowing into the base. The ‘tank empty’ inductor only turns off when the water reaches its sensor located in the base.

If you’ve already filled the tank, but the indicator is still flashing, try loosening the tank lid to allow the air to escape and water to reach the appropriate level in the base for the sensor to turn off the indicator.

Do ceramic filters in Air Innovations humidifiers need replacing?

No, ceramic filters in Air Innovations humidifiers do not need replacement. They are permanent filters, and with proper care and maintenance, they can last as long as the humidifier.

You should rinse them with water regularly, but be careful not to use dishwashing soap or detergent as they can actually crack the filter. 

Final Verdict: What is the best Air Innovations humidifier sold today?

Air Innovations has a range of good humidifiers, making it hard to settle on the best one.

However, we think that the MH-701B is the best choice for large spaces. It boasts the right balance of features and convenience and makes for a good purchase.

Meanwhile, for medium-sized spaces, the MH-408 is a good option.

And if you want a compact yet stylish unit, make sure you check out the AI-100 Cool Mist Humidifier.
