What forms the core of this model is a powerful built-in fan that pulls air directly from the furnace for humidifying and dispersing it throughout your home. 

Coupled with this is a pair of efficient sensors that work to monitor and respond to the outdoor temperature and the indoor relative humidity constantly. This action helps the unit deliver optimum humidity in your rooms, keeping your home ideally humid throughout the day. 

Moreover, this steam humidifier can add as much as 18 gallons of moisture to your home daily, which is perfect for eliminating the dryness of the air completely. And that’s not all; this amazing moisture-adding capacity makes it capable of providing coverage of 4200 sq ft. 

You can even control the humidifying action efficiently through the smart digital control panel on the bottom right corner of the unit. It lets you adjust the humidity level on a scale of 1-7.  

What Could’ve Been Better?

Installing this whole house humidifier can seem a bit difficult since the instructions only come in the form of a few pictures on a single sheet. As such, you will need to consult online guides to get the job done. You will also require purchasing a few extra fixtures, such as a water drain line, supply line, and thermostat wire. 

Pros
  • Powerful humidifying action
  • High moisture capacity
  • Large coverage
  • Efficient humidity control
Cons
  • Complicated installation
Type: Whole-house | Coverage Area: Up to 5,300 sq ft | Tank Capacity: 18 gal/day | Humidity Control: Automatic | Filter Type: Water panel

Are you looking for a cost-effective yet high-performing humidifier to help your little one sleep comfortably at night? Then the Vicks Vaporizer is a model you can count on. It can be equally effective for adults, helping them stay healthy throughout the dry winter months. 

Why Did We Like It?

First and foremost, we like the convenient design of this vaporizer which lets you carry it to any room in the home as per your needs. 

Adding to the convenience is a pair of lightweight molded handles that are also quite sturdy for long-term use. Thus, this unit ensures you’re always able to breathe better wherever you go. 

Using the vaporizer is also quite simple, as you just need to fill up the machine with water, insert the Vicks Vaposteam and connect it to a power outlet. Thereafter, you can relax and enjoy warm and humid air throughout the room. Even filling up the unit quickly and conveniently, thanks to an efficient easy-fill water level mark. 

Another noteworthy feature is its protective steam guard design, which helps lower the outlet steam temperature by 20%. This makes it a much safer option for use around children and small babies.  

What Could’ve Been Better?

The only drawback of this unit is that the indicator light on the cap can’t be switched off at night, which some might find slightly disturbing after going to bed. However, considering the efficient humidifying performance the unit offers, this can’t be called a deal-breaker after all.

Pros
  • Convenient design
  • Easy to use
  • Easy to refill
  • Safe for use around kids
Cons
  • No on/off button for indicator light
Type: Room | Coverage Area: Up to 400 sq. ft. | Tank Capacity: 1.5 gal | Humidity Control: Manual | Filter Type: Scent pad

3. Aprilaire 800 – Best For Ease Of Use

Why Did We Like It?

To begin with, this humidifying system not only relieves you from the hassle of filtering the water but also doesn’t require refilling any tank. You just need to connect it directly to the water source. And thereafter, it will humidify and disperse the air on its own using the internal steam pipes, canister, and dispersion tube. 

The only thing you will need to replace in the next humification season is the canister built exclusively for this model. But that’s not a problem since it can be purchased separately any time you want and is very easy to insert as well. Plus, the model comes with detailed instructions for the replacement, so rest assured that it will be a breeze. 

Not to forget the excellent coverage of 6200 sq. ft. offered, making it an ideal fit for medium-sized and tightly built homes.  

What Could’ve Been Better? 

Owing to the use of electrode technology, the power consumption of this model is much higher than many other steam humidifiers. As such, it increases the monthly power bill, which might not suit all homeowners. That’s why you’ll first need to figure out whether the increased power consumption would be viable for your home. 

Pros
  • Filter and tank-free
  • Directly connects to the water source
  • Easy-to-install replacement steam canister
  • Large coverage
Cons
  • Much higher power consumption
Type: Whole-house | Coverage Area: Up to 6,200 sq. ft. | Tank Capacity: 11.5 gal/day | Humidity Control: Automatic | Filter Type: Water panel

4. Honeywell HM750A1000

Honeywell is also known for its efficient range of electrode humidifiers, and one such popular model is the HM750A1000. A great advantage of this model is that it can be mounted on the wall or on the air ducts in your home as per the need. Notably, this feature can be found in very few humidifiers on the market.

  • Smallest footprint on the market for flexible,...

Why Did We Like It? 

Firstly, we loved how this model could be installed smoothly and much faster than other electrode humidifiers. The installation can even be carried out by one person with the help of some basic tools. 

Speaking of its internal parts, it comes with a pre-mineralized cylinder for humidification that helps to enhance the conductivity of the water getting in. As a result, the device is able to generate much more steam than ordinary models and can also start and shut down faster. 

This whole-house steam humidifier also includes a humidistat, which helps the user choose a precise level of humidity that it can function with reference to. This way, it maintains the desired humidity level in your home day in and day out. 

Another benefit is that the power consumption of this unit is much lower compared to other high-performing models such as the Aprilaire 800. Thus, it would never bring about an exceptional rise in your monthly power bills.  

What Could’ve Been Better? 

Being an electrode steam humidifier, this model will require a replacement canister at the start of each humidifying season. And this is where you’re likely to feel the pinch, as the canisters are priced much higher than that of electrode models from other brands. 

Pros
  • Smooth and fast installation
  • Facilitates better humidification
  • Lets you choose a precise humidity level
  • Low power consumption
Cons
  • Expensive replacement canister
Type: Room | Coverage Area: Up to 2,000 sq. ft. | Tank Capacity: 1.5 gallons | Humidity Control: Automatic | Filter Type: Antimicrobial wicking filter

5. AIRCARE Aria

Towards the end, we’ve included this steam humidifier from Aircare that performs considerably well in maintaining the humidity level in the desired part of your home. Rather than coming loaded with lots of features, this model offers a simple operation and is also a quite cost-effective option to go for.

  • Simple push button control and Easy fill removable...

Why Did We Like It? 

First things first, this steam humidifier consists of a removable tank with a capacity of 0.75 gallons. This makes it sufficient for uniformly humidifying small to medium-sized rooms for up to 12 hours. Its power switch is also designed to shut off automatically after the water is exhausted, thereby ensuring that the device keeps functioning consistently. 

At the same time, the refill indicator lights up to tell you that it’s time for a refill. Another beneficial feature is the presence of a powerful fan that disperses the humidified air efficiently to help you feel healthy and refreshed. 

What’s more, it includes a sturdy pull-out diffuser tray for adding essential oils of your choice. This lets you infuse an energizing fragrance throughout the room.  

What Could’ve Been Better?

If you wish to humidify a larger space, this model might not be the right option to go for. That’s because it offers coverage of about 380 sq ft, which will prove insufficient for uniformly humidifying such a space. So, make sure you consider the area of the space you plan to use it for before zeroing in on this model.

Pros
  • Uniform humidification for small spaces
  • Efficient refill indicator
  • Lets you create a fragrant atmosphere
  • Auto shut-off switch keeps the device safe

Buying Guide For The Best Steam Humidifier

To ensure that the model you choose is perfect for your needs, it’s essential to consider some key features that influence the overall performance of a steam humidifier. Remember that making a hasty decision might not fetch you the desired results. So, here are the three most important points you need to keep in mind: 

1. Coverage

Like an air conditioner, the surface area of the space where you wish to use a humidifier is crucial for its performance. Hence, don’t forget to consider the size of the room you will use it for. 

Note that the small and easy-to-carry humidifiers are suitable for use in single rooms and come with a recommended room size too. But in case you wish to use it for the entire house, you should look for steam whole-house humidifiers that provide much larger coverage.

2. Maximum Output And Mist Time

It’s essential to consider the maximum amount of mist a humidifier can produce daily as that determines the efficiency of the model to a great extent. That said, this measurement applies to a particular time frame as well. Together, these parameters indicate the ability of a model to humidify a space effectively. 

This is why you’ll always find the moisture output of a model mentioned in terms of gallons per day. The more this figure, the greater will be the humidifying power of a unit. So, make sure you check the moisture output of the model you’re considering.

3. Running Cost

The cost of running a humidifier is essentially the amount of electric power it requires to enable uniform humidification. Note that it’s especially important to consider this factor when you’re buying a humidifier for the entire home. That’s because such a model would need more power to run and hence is more likely to affect the running costs. 

So, make sure you check the customer reviews of the humidifier you’re considering to get an idea about the power it will consume.
