If you’ve been using single room humidifiers in each room in your house, you may have noticed a slight increase in your energy bill. These slight increases can take away comfort from your pockets. But that can never be the case when you install any of the best whole house humidifiers we are reviewing today.

There’s no better way to keep the air in your room from getting dry other than using a humidifier. If there was, there wouldn’t be any need for this best whole house humidifiers review.

For individuals who love whole house appliances like whole house water filters, this review will surely educate and point you to the right spot as you shop for a new whole house humidifier.

Let’s skip the definition of a humidifier – better still, let’s summarize it for our folks who don’t know. Simply put, a humidifier is a device that keeps the atmosphere in a room moist. At least, that’s how Wikipedia defines it. As we earlier hinted, there are 2 categories of humidifiers;

  1. Point of Use Humidifiers: As the name implies, they are the type of humidifiers used in a single room. They are often referred to as single room humidifiers.
  2. Whole House Humidifiers: Just as in the case of whole house water filters, a whole house humidifier humidifies the air in all the rooms of the house. Sometimes, they are referred to as furnace humidifiers when they are installed in furnace areas alongside your furnace. More so they are connected to HVAC systems from where they deal with the dry air in the whole house.

We believe that you’re interested in getting one of these best whole house humidifiers for your home. You’ll get to read our expert reviews but not until you read the following.

The first humidifier to grace the top of our list today is the Aircare EP9800 humidifier. It’s one of the most recommended whole home humidifiers. Arguably, the Aircare EP9800 is the best whole house pedestal style humidifier. It features a three and half gallon tank for storing water. This sizable tank provides the EP9800 with more than enough moisture to take away the dryness from the air in your home. It uses a saturated wick filter instead of the fabric belt found on some other whole house humidifiers.

Design wise, the Aircare EP9800 humidifier comes in a spot-on black finish that makes it fit properly into any background where it’s placed. From any point where it is placed in your home, the Aircare EP9800 keeps the humidity level hovering between 30% and 50% depending on the settings you specified. As with most humidifiers, you’re guaranteed of comfort as well as protection for your priceless wooden objects. The Aircare EP9800 humidifier boasts of the ability to humidify an area of about 2400 sq. ft. This makes it one of the most suitable whole-home humidifiers for large houses.Also worth mentioning is the fact that the EP9800 humidifier boasts of an incredible 60-hour runtime. Seriously, that’s a pretty good deal unlike competition with less than 24 hours runtime.

The Aircare EP9800 comes with an auto shut off feature. Once your EP9800 humidifier reaches your set humidity level, it will automatically shut off. So you can humidify your home while you’re away in the office. Cool, isn’t it? Installation wise, the Aircare EP9800 humidifier is not too difficult to install for someone who’s familiar with the installation of whole house appliances. If, however, you are skeptic about installing it, then you can employ the services of an expert.

Housed in an all-white resplendent casing, the Aircare MA1201 deserves to be on our review list. This whole house humidifier is effective in keeping the humidity of an area of 3600 sq. ft. at the normal level. Oh yes, it covers more area than the Aircare EP9800 humidifier.

Unlike the EP9800 and some other models that cannot be moved by one person, the Aircare MA1201 humidifier is simple to move, thanks to the wheels on its base. The MA1201 humidifier sports a digital humidistat which can be set to automatically carry out a variety of functions. This also helps you to set your desired humidity. The auto shut off feature which is now a standard for many products takes care of the rest when the set humidity level is reached.

The Aircare MA1201 humidifier is easy to clean and install. It comes with an inbuilt evaporative wick that traps mineral deposits in the water. This ensures your air is not contaminated. For cleaner water, the water should be distilled using the appropriate water distiller.

Under the hood, the Aircare MA1201 humidifier boasts of up to 36 hours runtime and a 3.6-gallon tank. Both features allow the device humidify your house on autopilot. Refilling the water is as easy as ABC as the humidifier uses dual easy fill water bottles that come with refill hoses.

Sitting princely on the third position on our review of the best whole house humidifiers is the Aprilaire 500 Whole House Humidifier. It’s the first Aprilaire product we are reviewing, so let’s see if it stacks up to the standards of the Aircare humidifiers.

The Aprilaire 500 humidifier is a bypass humidifier and is touted to be the best in its class. It is designed to keep the air in an area of 3000 sq. ft. constantly humid for several hours at a stretch. Aprilaire didn’t provide us with the maximum runtime for the product nor did they provide the tank capacity. On the other hand, the Aprilaire 500 is designed to provide up to 0.50 gallons of humidity every hour.

It comes with automatic controls that make use very easy. Additionally,  it features a drain hose which is used to flush the unwanted water particles away from the humidifier since it’s a bypass model. This ensures that the water that is being used to humidify your home is at least clean enough for your health. The unit can be installed directly with the central heating and cooling system in your home.

Did we mention that the Aprilaire 500 comes in two variants; 500 and 500M? The 500 is the digital model while the 500M is the manually controlled model. Each of these models comes with a water panel change indicator. The change indicator notifies you of when it’s time to change your humidifier’s water panel. Arguably, this will ensure you keep getting clean air all year round.

Honeywell HCM-6009 Cool Moisture Console Humidifier

The Honeywell HCM 6009 Cool Moisture humidifier is one of the few whole house humidifiers on our list that blows cool mist. This humidifier is a member of the Quietcare series from Honeywell. It’s a console style humidifier with a coverage range of about 2300 sq. ft. With the Honeywell 6009 humidifier, the discomfort that comes with dry air is driven far away from your home.

Honeywell equipped this humidifier with a 3-gallon water tank. Surprisingly, this provides up to 24 hours of uninterrupted humidity in your small and medium-sized homes. One of the most amazing features of this humidifier is the auto on and off feature. It is pertinent to note that some of the models we saw and tested during the course of our review had only the auto shut off feature.

Just like the Aprilaire 500 humidifier, the Honeywell HCM 6009 humidifier comes with a wicking filter. The wicking filter helps to remove minerals from the water you put in the humidifier. Aside from that, the humidifier has 3 different speed settings which can be adjusted to suit your taste. Did we mention that the tanks on this model are out of this world? Yes, first, they are easy to fill and carry and secondly, they are easy to clean.

Main Features

  • Easy to clean and refill 3- gallon tank
  • An average coverage area of about 2300 sq. ft.
  • Soothing cool mist for your body and your home.

  • Speed is adjustable
  • Automatic on and shut off feature triggered by the level of humidity in your home’s atmosphere.

We’re almost halfway down our review of the best whole house humidifiers. Now, we’re taking a look at the Aprilaire 600 humidifier auto, a close cousin of the Aprilaire Model 500 humidifier. They share quite a handful of similarities but there are quite some distinguishing features. Let’s find out.

The Aprilaire 600 humidifier was designed to be flawlessly easy to operate and install. One cool feature on it is the permanent memory feature. In the case of a power outage, your humidifier remembers all the instructions you gave to it. Talk about being a good boy! Additionally, the humidifier features a 7-day programming copy function.

This copy function allows you to program different humidity settings for each day of the week. It’s quite handy especially if you experience varying humidity levels in your home on different days. Did we also mention that the humidifier sport programmable fans unlike some other humidifiers on our review list? The Aprilaire 600 humidifier auto has an internal mesh evaporator filter inside of it. This filter is connected to a drain which removes any water that is not evaporated by the humidifier.

Furthermore, professional knowledge is not a prerequisite for installing the Aprilaire 600 humidifier. The humidifier boasts of a wide coverage area of about 4000 sq. ft. and the more tightly constructed the home is, the better – at least, that’s what Aprilaire says.

Main Features

  • A massive coverage area of 4000 sq. ft.
  • Copy function that allows you to choose different humidity settings for 7 different days of the week.
  • Programmable fan speeds
  • Internal mesh evaporator
  • Drain hose for draining any external water.


  • Large coverage area.
  • Varying adjustable fan speeds for optimal humidity in the home.
  • Option to set different humidity settings for 7 different days.


  • You cannot adjust the humidistat on this humidifier
  • Might require the help of a HVAC expert to install if you’re a newbie in DIY installation of humidifiers.

Vornado Evap40 4-Gallon Humidifier (Best Whole House Humidifier For Small Homes)

Breaking away from the norm of 3-gallon tank humidifiers is the Vornado Evap40 4-gallon humidifier. This whole house humidifier is suitable for just small apartments with two to three rooms. It’s designed to humidify an area of about 1000 sq. ft.

One of the reasons why we’re reviewing it is because of the fact that there are homeowners who prefer this since they’re on a budget. The humidifier uses a unique mode of operation called the vortex circulation. It’s actually peculiar to this type of humidifier – we haven’t seen it in other humidifiers.

The Vornado Evap40 humidifier comes with an option for selecting variable speed settings. Hence, you can choose either low, medium or high from the 3-speed options that are available. There is also a near accurate humidistat which automatically ensures the humidity in your home is controlled appropriately.

With the Vornado Evap40 humidifier, you get at least 24 hours of uninterrupted humidity, thanks to its 4-gallon tank. The 4-gallon tank is a tad higher than the average 3.5-gallon tanks we’ve seen so far. The tanks are easy to fill and are designed to be spill and leak proof. It’s quite surprising to see an unpopular whole house humidifier with such specs. In comparison to other best whole house humidifiers on our list, it stacks up nicely.

Video Review:

Main Features

  • Massive 4-gallon spill and leak proof tank.
  • 24 hours runtime
  • Adjustable speed settings
  • 1000 sq. ft. coverage area.


  • The 4-gallon tank is quite impressive
  • 3-speed settings to choose from
  • A full day of comfort in your home.


  • Wick filters require frequent replacements always.
  • Setting the speed to low won’t humidify your home at all.
Aircare H12-400HB 3-Speed Whole House Console Style Evaporative Humidifier

We don’t know what Essick Air was thinking when they accepted the design papers for the Aircare H12-400HB humidifier. At first sight, you’ll probably think that you’re looking at a vintage washing machine. That’s how one of our reviewers felt when he set his eyes on the product. We do like the oak burl look of the humidifier – eye-catching and different from the white color we’re used to.

As large as the H12 humidifier is, it sports only a 5.4-gallon tank, a tad above the 4-gallon tank found on the Vornado Evap40 humidifier. Additionally, it is only capable of providing humidity for an area of 3700 sq. ft. – quite disappointing given the product’s size. On the other hand, Essick Air made up for that by equipping it to work for 45 hours nonstop. This implies that the maximum runtime of the humidifier is 45 hours. Apparently, it’s the best we’ve seen so far during the course of this review.

On one corner of the humidifier are analog control buttons for your settings. The humidifier does, however, come with a digital display screen to complement those buttons. The humidistat is quite impressive on this product and the same can be said for the fan. Fan speed is adjustable on the device and you have 4 options to choose from.

Main Features

  • 4-gallon tank
  • A sizeable coverage area of about 3700 sq. ft.
  • Amazing 45 hours maximum runtime
  • Analog controls with a digital screen
  • 4 adjustable fan speed options


  • Coverage area is impressive
  • The humidifier lasts longer than most other whole house humidifiers.
  • Control options allow you choose your own variable humidity settings and fan speeds
  • Near accurate humidistat
  • Indicator showing when to refill and check the filter.


  • A bit bulkier than you would expect.
  • Plastic body makes it susceptible to cracks easily.

The Aircare MA0800 Digital Whole House Console Style Humidifier is another masterpiece from Aircare. Sporting quite a few handy features, this humidifier held our attention long enough and thus we’re reviewing it.

The MA0800 humidifier is built to cover an area of about 2600 sq. ft. It comes with an easy fill water tank that is capable of holding a paltry 2.5 gallon of water. Aside from that, the MA0800 humidifier is able to utilize such limited amount of water for up to 36 hours.

Just when you thought you have seen it all, Aircare surprises you with one cool feature. The Aircare MA0800 humidifier comes with a quiet night time setting. This will help you keep the operation of the humidifier low whilst you sleep. The auto shut off feature, as usual, turns off the humidifier once the set humidity level is reached. Furthermore, there are 3-speed options to choose from. You get a digitally controlled humidistat with a digital display screen.

Main Features

  • Digitally controlled humidistat.
  • A moderately sized coverage area.
  • 5-gallon water tank.
  • 36-hours runtime.
  • 3-speed options to choose from.


  • The humidistat is digitally controlled hence boasts of fairly accurate readings.
  • Variable speed options to set with a Quiet night time mode to set when you’re asleep at night.
  • Up to 36 hours of uninterrupted humidity in your home.
  • Coverage area of 2600 sq. ft. is apt for not so large homes.


  • The humidifier can rattle at times when set on high fan settings

Do you live in a mansion? If your answer is yes, please proceed to take a look at the specs of this massive whole house steam humidifier. On the other hand, you can simply take a look at the other best whole house humidifiers on this review list.

The Aprilaire 800 Residential Steam Humidifier is quite big in terms of physical size and functions. First, it’s as big as the Aircare H12-400B humidifier although we didn’t measure them for their exact dimensions. Secondly, it covers a massive 6000 sq. ft. Now, that was why the question “Do you live in a mansion?” was necessary.

Aside from being able to humidify such a large amount of space, the Aprilaire 800 has a runtime of 60 hours. The humidifier delivers the right amount of humidity needed at any given time. It’s controlled via the automatic digital humidifier control panel. Aprilaire designed the humidifier to run without being installed directly with a HVAC system. Installing the Aprilaire 800 requires a little bit of technical knowledge. It is advisable to seek the installation services of experts rather than installing it and damaging the product in the process.

Main Features

  • A massive coverage area of 6,000 sq. ft.
  • A whopping 2 and half days maximum runtime
  • Digital controls for your controlling pleasure
  • Can be installed independently of your homes HVAC system.


  • A large coverage area of 6000 sq. ft.
  • 60 hours of uninterrupted humidity
  • Easy to set and control via the digital control buttons.


  • Some users reported that much of the water drained out.

Last but certainly not the least of the humidifiers on our best whole house humidifiers review list is the Aprilaire 700 humidifier. There’s no doubt that Aprilaire is a force to reckon with when it comes to the production of durable and superb humidifiers.

The Aprilaire 700 humidifier is designed to evaporate about 0.75 gallons of water per hour. This explains why it sports a sizeable storage tank. However, Aprilaire didn’t fully specify the gallon size of the humidifier. The Aprilaire 700 humidifier is designed to cover an area of 4200 sq. ft.

Controlling the humidifier is as easy as ABC, thanks to the automatic digital humidifier control panel. There isn’t much to say about the Aprilaire 700 save for the fact that it offers you great value for your money.

During the course of the review, we found out that installing the product is a breeze for professionals. The same cannot be said for people without prior installation experience. With multiple installation instructions to follow, one will definitely be confused along the way. One other thing we didn’t like about the Aprilaire 700 is the fact that it didn’t come with any thermostat.

Reasons Why You Should Use A Whole House Humidifier

Dry air apparently has a way of making everyone at home uncomfortable. To combat this discomfort, many families purchase humidifiers. With their humidifiers came a handful of benefits…


With a whole house humidifier, you’re guaranteed great benefits.

In this section of the review, we shared 6 benefits you’ll derive by simply using a whole house humidifier.

Humidifiers Help Reduce Health Risks

Respiratory-related infections and ailments such as bronchitis, sinusitis, nosebleed, and asthma are triggered by dry air. The chances of worsening these health situations decrease drastically especially when your humidifier is in active service. Since whole home humidifiers have a longer lifespan, they keep the whole house moist for as long as you need them.

They Make You Comfortable

You are entitled to a certain level of comfort with regards to the air you breathe in your home. Only a humidifier can do that when it’s dry air season. The dry air which would have caused discomfort to your body and respiratory system is eliminated.

Preserves Your Home

Talk about preservation and humidifiers stand up. In the absence of moisture in your home, there’s no telling what will happen to wooden objects and surfaces. This suffices to say that humidifiers help prevent damage to wooden surfaces in the home.

Saves Cost

Truth is, many people think installing a whole home humidifier is very expensive. It isn’t, literally. To be frank with you, even if it was expensive, you’ll benefit from it in the long run. Using whole house humidifiers, you will possibly add a few cents or dollars to your water bill. However, you save more since you don’t need to purchase distilled water. It’s a fact that most single room humidifiers need distilled water to function effectively. Imagine the amount you’ll spend on buying distilled water for 3 or 4 single room humidifiers! That amount will definitely add up to something significant within a short period of time.

Control Over Your Home’s Humidity Level

Generally, all humidifiers allow you to control the humidity level in your home. Through these settings, you impede the growth of mold and mildew which can be triggered by much humidity. Using a whole house humidifier, you’re in charge of your comfort, health, and happiness – as well as that of your pets.

It’s Energy Efficient

Did you know that you can shave a few cents from your energy bill when you use a whole house humidifier instead of a single room humidifier? Raise your hand if you don’t want to shave off a dollar or two from hour energy bill!

Having known these benefits of whole house humidifiers, we’re sure your interest has been ignited. In the lines that follow, we’ll review the best whole house humidifiers 2019 has brought our way. But before
