10 Best Whole-House Humidifiers for you Reviewed

Whole-House humidifiers come in various styles, furnace-mounted types that can directly be connected to the HVAC system in your home, wheeled models, and units that come as standalone.

These are standard humidifiers that meet the safety standards to be used in your home. But, don’t tarry to ask the experts if something is not clear.

1. Best Value: AIRCARE 831000 Space-Saver Evaporative Whole House Humidifier AIRCARE

This low-cost whole-house humidifier is meant to be placed on the floor and starts working immediately, unlike other choices that require installation and plumbing knowledge.

It’s also light and portable, weighing only 14 pounds.

Despite its low price, this humidifier has many features, including a filter check indication and an auto-shutoff feature that takes charge when your home’s humidity level is achieved.

It’s a space-saving whole-house humidifier with a modern design. The top of the device draws in dry air, which is moistened as it travels through the reservoir’s evaporative wick and disperses back into the air.

With this humidifier, refilling the water is a breeze. Because it’s filled from the top, all you have to do is pour water directly into the reservoir from above. As with other humidifiers, no tilting or turning is required to achieve a satisfactory filling angle.

A strong Trapmax filter is included with the Aircare 831000. It traps allergens and has antibacterial qualities, making the air cleaner.

We recommend changing the wick at the beginning of each season. If you reside in a location with hard water, you may need to replace your filter more frequently.

The model’s 7-gallon water tank allows it to run for up to 70 hours before needing to be refilled.

It has a bright LED display that makes selecting your chosen humidity level simple.

The refill indication lets you know when to replenish your water supply. However, if you neglect to fill the humidifier, it will turn off automatically to prevent damage.

The three fan speeds allow you to adjust the temperature during the day and night.

The casters make moving the device around, including replenishing the reservoir.

Fan blades are super easy to access and clean – unplug the machine, remove the top housing, and turn the housing upside down to access and clean the fan blades.

The direction of the blower is set at 45 degrees upward. However, this should not be a problem because the humidifier can be rotated.

On the second or third fan speed, it becomes noisier.

Appropriate for homes with a square footage of up to 2000 square feet or more – position the humidifier at the bottom of the stairs in two-story homes.

2. AIRCARE Valiant Digital Whole-House Console-Style Evaporative Humidifier

AIRCARE Valiant could be a good choice if you want the portability and convenience of a standalone humidifier with the coverage of a furnace-mounted humidifier.

The digital humidistat automatically maintains the ideal humidity level in your home or the level you specify.

You can also use a digital interface to monitor the humidity in your house, which displays both the current and ideal humidity levels.

With the ability to adjust humidity levels in houses up to 4,000 square feet, this compact, quiet humidifier packs a more significant punch than its size suggests.

The 5-gallon tank can humidify your home for up to 55 hours on a single refill.

The oak finish, while artificial, allows this humidifier to blend in a little better than a black or white type.

The water level indicator is quite useful, and you won’t worry about unexpected refills.

It uses evaporative technology to humidify without producing a visible mist, and it shuts off automatically once you’ve reached the desired humidity level.

This tower humidifier is meant to look and work like a side table to fit right in with your living room decor. It even comes with a top tile that you can change to suit your flooring and furniture.

The unit itself takes the responsibility of shutting down and makes it easy to use. The shutdown mechanism is activated when the required humidity level is reached.

When this fan is spinning at high speeds, users say the noise is off-putting.

The H12-600 also includes a high-output evaporative wick that retains minerals while delivering clean, natural moisture to the air and a new four-speed fan that lets you choose your preferred degree of performance.

The digital humidistat automatically maintains your preferred humidity level. Further, set your desired humidity level anywhere between 25% and 60% in 5% increments (continuous always-on mode when set to 65%)

You have four fan speeds at your disposal to achieve your desired performance level.

When the appropriate humidity level is reached, or the device is empty, it automatically shuts off.

The digital display shows the current humidity level, the ideal humidity level, and the fan speed.

Thanks to the removable power pack and evaporative cooling, cleaning is super simple.

The filling is simple with the removable 2.5-gallon water bottle that you easily lift out for convenient filling at your sink with the fill hose (included).

There are four speeds to choose from, giving you the option of power output or low noise.

7. Best Portable Whole House Humidifier:  Vornado Evap40

It would be a squander of funds, but it would also put you at risk of mold due to the excessive moisture blasted into the air.

It could be the best option if you live in a smaller home.

Its maximum output and coverage area are minimal, making it ideal for compact living spaces. It also means that the tank will require more frequent filling than other types.

8. Aprilaire 700 Whole Home Furnace Humidifier 

Aprilaire 700 Whole Home Furnace Humidifier 

Aprilaire 700 is the most user-friendly appliance because you may operate it in either a manual or digitally programmed mode.

These two modes will allow you to choose the appropriate relative humidity level in your house.

One of the more challenging aspects of using a whole-house humidifier is being cautious with the water you run through. Some models are incredibly picky about the water they use, and if you use anything other than that, you risk destroying the machine.

Luckily, this device does not require you to use specific water. It will be able to handle any type of water, including distilled, soft, hard, hot, or cold.

If you opt to buy this humidifier, ensure you have it installed by an expert. Because it must be connected to your furnace, it might be a little tough to get just right.

This humidifier has it all: a reputable name, a reasonable price, furnace installation, twin sensors for hands-free humidification, and more.

We particularly like the digital control interface because it allows us to make quick modifications and receive notifications.

Guide to Buying Whole-House Humidifier (What to consider )

It’s simple to get the best whole house humidifier for any home when customers know these devices’ most significant technical and practical qualities.

Not all whole-house humidifiers are created equal, and there are several factors to consider before purchasing one, mainly because some models may be costly.

When choosing the best whole house humidifier for your home, it’s not just about finding one that looks great and is reasonably priced; there’s a lot more to think about.

Some appear to be attractive, but appearances aren’t everything.

In the following sections, we’ll go through some of the most common humidifier kinds and essential factors to consider so you can make the best decision possible.


One of the most crucial factors to consider when buying a humidifier is your home’s size.

The majority of whole-house models have a capacity of 1,000 to 4,000 square feet. However, some have higher or lower capacities.

Look for a product that explicitly indicates it can cover homes of that size (5,000 square feet or more).

It’s also good to check with an HVAC professional to ensure it’ll function in your space.

Type of whole-home humidifiers

The first step is to figure out what type of whole house humidifier you want and whether it will work with the size of your home and the HVAC system you already have.

There are two types of whole-house humidifiers, one that can work with an existing HVAC system and free-standing console versions.

Different installation requirements apply to humidifiers that interact with an HVAC system.

Some can be installed by a layperson, while others will require the assistance of an HVAC engineer.

Whole-house humidifiers that work with HVAC systems require little maintenance because they’re wired into their existing electrical and water supply systems.

A whole-house humidifier might be one of three types that work with an HVAC system:

Steam humidifiers (the most efficient but also the most expensive).

The most potent humidifiers are steam humidifiers, commonly used in large homes.

They boil water in a steam canister before releasing the steam through the ventilation ducting.

Also, they can be costly, and their energy usage is higher than that of other models.

Bypass humidifiers (furnace-mounted).

Instead of heating the water, bypass humidifiers utilize the heat from the furnace. A panel holds the water, which is usually changed once a year.

These are highly reliant on your furnace and will almost certainly necessitate the installation of additional ducting.

It can make them a little too complicated at times, and they’re better suited to homes with the requisite ductwork already installed.

As with a steam humidifier, water particles flow through the ducting.

Fan humidifiers

Instead of using heat, fan humidifiers blow air across a saturated humidifier pad.

Ducting is used to expel fine water particles.

They are more energy-efficient, and they do not affect the air conditioning because no warm air is present.

Evaporative humidifiers (warm or cool mist can be noisy).

Evaporative humidifiers are the most prevalent type of whole-house humidifier. These can be portable humidifiers that can be moved from room to room or humidifiers attached to your HVAC system and add extra humidity to the heat generated.

These usually are best suited to smaller homes and rooms, but if you have a portable one, you can use it in other places because it is movable.

They work by forcing air through a saturated wick filter through a fan or heating system.

Because they don’t use steam, bypass and fan humidifiers are sometimes known as evaporative humidifiers.

Console humidifiers are a lot easier to use. They only need to be regularly positioned where you want them, filled with water and plugged into an accessible power outlet.

There’s also the issue of background noise.

Permanent installations near the furnace rarely generate a perceptible noise in the living room, although console whole-house humidifiers can make significant noise at high fan settings.

Because cool mist models require a fan to project moisture, they are the loudest. Warm mist and ultrasonic humidifiers, usually only available on room-size humidifiers, do not have a fan and are quieter.


Many whole-house humidifiers work by introducing warm or cool mist into the air.

A warm mist whole house humidifier serves the dual aim of boosting humidity and temperature in chilly conditions.

In such circumstances, cold mist may be detrimental, lowering the home’s temperature even further.

A cool mist whole house humidifier, on the other hand, will be ideal in warmer conditions.

It has two functions: it lowers the temperature and humidifies the air in your home.


Pick a design-forward unit that doesn’t clash with your decor when placing it in the open. The following are the crucial features of whole-house humidifiers:


A humidistat (also known as a hygrometer or hygrostat) is a built-in sensor in most whole-house humidifiers that detects humidity levels and switches the device on and off to maintain a consistent level.

It provides the right comfort level, saving water and energy.

Water tank indicator

This feature is essential for determining when your tank is empty or running low.


The auto shut-off function is convenient if you think you are the forgetful type.

Water level monitoring is standard on console whole-house humidifiers, and if the water level falls below a certain threshold, the unit will shut down to prevent harm.

Filter indicator

Humidifiers with built-in filters purify the air in many cases, but not all. These are useful, but they aren’t necessary.

Filter indicators are helpful for quickly determining whether the filters are working correctly.

Because a clogged filter can leak pollutants back into the air and pose a health danger, it’s essential to clean it out regularly.

Refill Indicator

Maintenance is simple with the refill indication.

Coverage area

The coverage area tells you how much space you can humidify.

One of the most crucial factors to consider when purchasing a humidifier is the coverage area for which it is best suited.

You won’t get the correct humidity levels if you choose one designed for a coverage area that is either larger or smaller than your home.

To go even further, if the coverage area is much larger than the size of your home, you’ll be spending a lot more on bills because the more significant the coverage area, the more energy is used.

Another problem is that your home is likely to be considered too humid, leading to problems like mold.

While several intelligent DIY hacks can enhance the moisture level in a home environment without the added expenditure of a new unit, these are neither practical nor consistent and dependable options for providing coverage across the entire home.

The size of the coverage area required is determined by the size of the home.

Console whole-house humidifiers are often less powerful and have a smaller coverage area than their HVAC counterparts.

They span a range of 2,500 to 3,600 square feet, which should be enough for most households. On the other hand, HVAC systems can humidify spaces up to 6,000 square feet.

When looking at the coverage areas available, the term “tightly built home” is frequently used. This fully insulated living space with correctly fitting doors and windows creates a well-sealed internal environment.

Older houses may not be as well constructed.

Those who aren’t insulated or have periodic drafts may need a 40 to 50% more robust model for successful humidification.

Alternatively, the flaws could be addressed.

Not only might a less expensive humidifier be utilized, but the home would also become more energy efficient in general, lowering heating expenditures.

There’s another factor to consider when it comes to coverage, and it has to do with the sort of whole-house humidifier you choose.

Even closed rooms acquire humidity if you have one that operates with an HVAC system.

A closed-door on a console model isolates a room from the humidified air supply.

Weight & dimensions

You’ll need to carefully coordinate the size and weight of your new humidifier with the size and weight of your house’s furnace and the amount of space you have to work within your basement area.

Because most humidifiers are connected to your HVAC system, you’ll want to ensure your furnace can withstand the added weight.

If you don’t think you’ll have enough space to install your new humidifier, a more portable type, such as the AirCare MA1201, would be a better option.

You’ll be able to place your new humidifier wherever you choose without worrying about it interfering with your existing HVAC system.

Maximum output per day

How much humidity can the humidifier output to the environment?

The maximum output per day refers to the amount of moisture your humidifier can release into the air throughout 24 hours.

It is critical to think about how much the maximum output of any humidifier you’re considering is. It is another balancing act since you’ll want to make sure it meets your daily requirements.

If you use too much, you risk mold, and if you use too little, your home will seem dry rather than humidified.

System compatibility

If you live in an older home with an older furnace, it’s possible that you won’t be able to connect your new whole-house humidifier readily.

It is also true for any heating system that does not use forced air to heat your home.

Most whole-house humidifiers types cannot be installed if your home has radiators rather than air ducts.

Also, consider if the air humidifier you’re contemplating is suitable for your home and heating system.

You should keep in mind that, except for portable humidifiers, all humidifiers will not work in your home if you have central heating instead of forced air heating.

Even if air ducts are used, there is no guarantee that the humidifier will operate with them. It would help double-check that your heating system and whole-house humidifier are compatible.

Before you go out and buy a whole-home humidifier, make sure you take a close look at your heating and cooling systems.

Nothing is more aggravating than getting it home and attempting to install it only to discover that it is incompatible with your heating system.


When shopping for a whole-home humidifier, be sure it comes with a solid warranty, as with most equipment. There are numerous moving parts in these machines.

They also operate with water, which can cause a slew of issues even if all of the proper maintenance procedures are followed.

You should think about the guarantee you’ll be offered and any other extra features the whole house humidifier may have.

The latter could feature the ability to be programmed rather than constantly manipulated manually and an exceptionally easy-to-read display.

If you don’t change the pads and filters regularly, your warranty may be void.

When looking at the various warranties available, read them thoroughly.

Many of the warranties available are limited in scope and will only apply if you maintain the equipment properly.

The Humidifiers Dimensions

Is your basement big enough for a whole-house humidifier? Is it manageable in terms of size and portability? And will your furnace be able to handle the additional load?

Because several humidifiers will need to be linked to your house’s HVAC system, size and weight should always be addressed.


Humidifiers make a lot of noise because of their fans.

Warm mist and ultrasonic humidifiers are the quietest on the market. Unlike cool mist humidifiers, these two types do not require the vapor to be discharged into the atmosphere by a fan.

The noise created by the fans on the high setting may be loud enough to wake you up. It is an important consideration, particularly in homes with babies or light sleepers.


Can you switch it off while the humidifier runs? It can be annoying to light sleepers.


Size, weight, and availability of casters for mobility. These are critical when the intention is to move the humidifier from one room to another instead of having a fixed one.

Water refill method

The standard methods for water refill are top vs bottom fill. Bottom fills are more prone to leaks.

Ease of cleaning the water reservoir

Regular cleaning is necessary to prevent mold growth. As a result, getting a whole-house humidifier that is easy to clean is the priority.


It would be a disappointment to discover that your humidifier is only suitable for one room when you have four?

Before making a purchase, it’s critical to understand the capacity.

Humidifiers for the entire house should be able to cover a few thousand square feet.

When determining a humidifier’s capacity, it’s critical to inquire about the mist output.

With a higher output, your spaces will be humidified more quickly.

Water Tank size and Runtime

This functionality complements the capacity wonderfully.

Humidifiers for the entire house cover a lot of ground. It has a direct impact on how much water they require to function.

You wouldn’t want to replace your tank every hour or day.

Humidifiers that are set to their highest settings will use more water. The ability to go for extended lengths of time without having a refill is a huge plus. Also, look out for one that has a water tank that can be simply removed.

The supply is constant since whole-house humidifiers are plumbed into the HVAC system. Though, a water consumption rating is still offered in most cases.

Console models are not connected to the plumbing system in the home. They contain onboard water tanks that must be replaced regularly.

The regularity with which something is required will impact overall convenience. They can’t offer humidification when the tank is empty. Therefore, the Runtime suffers as a result.

The efficiency with which the humidifier operates, the coverage area, and the degree of humidity required by the inhabitants all have an effect.

It’s difficult to claim, for example, that a particular tank size provides a certain amount of Runtime.

When distributing humidity across a smaller area, a small device for a 1,500-square-foot home may run longer than a large one for a 3,000-square-foot home, but it will empty much more quickly if the room is beyond its intended capacity.

Because there is no universal runtime standard, each model must be examined and compared to others with similar results and features.

On the other hand, most units last from 24 to more than 40 hours between refills.

Manufacturers provide sufficient recommendations within product specifications, but moisture loss from unsecured doors and windows and a lack of insulation will likely affect Runtime.

Extra features

While some units allow for on-the-spot refilling, others require filling the tank from a faucet.

Given that a gallon of water weighs over 8 pounds, two small tanks may be more practical than one colossal tank.

As found with the Aprilaire 600, a persistent memory is another fantastic feature to make your life easier. This function ensures that your programming is not lost in a power outage in your home.

The remote control is essential if the humidifier’s ideal placement may not always be the most convenient for you. Another advantage is the ability to control fan speeds, which allows the user to increase humidity or run the device silently and swiftly.

Intelligent controls via phone apps and connections with home management systems are growing popular. However, the options are currently limited.

A programmable model with an easy-to-read display is one of the top characteristics to seek to make your life much easier. You can quickly and simply ensure that your humidifier operates just as you want. The Aprilaire 700 has an easy-to-read display and may be controlled manually or via a program.

Set up

You should also think about the setup needs.

Some whole-house humidifiers, such as those mounted on the furnace, require professional installation.

Consoles, pedestals, and other free-standing units are typically easier to set up, though maintenance needs and the frequency with which you must replenish the water tank vary.

What Are the Benefits of a Whole House Humidifier?

During the dry months, a humidifier adds moisture to the air, bringing it to a comfortable temperature for you, your pets, and your plants.

The advantages of a whole-house humidifier include:

  • It relieves dry air discomforts such as scratchy throats, dry skin, and eyes for you and your pet.
  • Encourages the growth of healthier plants.
  • Static electricity is reduced, which protects home electronics.
  • It nourishes your home’s wood and leather items.
  • Ensures that musical instruments are kept in the best possible condition.
  • In the winter, increased humidity aids in heat retention and lowers heating costs.

Whole-Home vs. Large Room

All of the alternatives on this list are powerful enough to humidify entire homes of various sizes.

Still, you’ve probably also come across options marketed as large room humidifiers during your research.

Large room humidifiers are designed to humidify a single room with a covering area of 500 to 750 square feet, though they can handle more or less space.

While that power level may be sufficient for a modest, open-plan studio apartment, anything more significant will require a whole-house humidifier.

HVAC System Humidifier vs. Console Humidifier

You’ve probably observed that some humidifiers require extensive installation and integration with your existing HVAC system, while others are simple plug-and-play console humidifiers.

It’s all up to you whether you go with an HVAC system-compatible humidifier or a console humidifier, but you should weigh the advantages and disadvantages of each.

HVAC system humidifier

Installing a humidifier in an HVAC system may necessitate the services of a professional, although they can be solid, and noise is usually not an issue.

Console humidifier

Console humidifiers are easier to set up, but they must be filled regularly, and the fans can be noisy.

What are the Costs Involved in Running Whole-Home Humidifiers?

The cost of each home piece of equipment is determined by how much electricity it consumes every month.

On the other hand, a whole-house humidifier will only consume as much electricity as is required to keep your home moist.

It will also be determined by the size of your home since the more significant the area to be humidified, the longer your humidifier will need to run.

You must also be aware of your specific model and the type of humidifier.

They’ll each use a different quantity of power.

Because of the various weather conditions, the price of running a whole-house humidifier will change from one household to the next.

According to our study, monthly costs should range between $20 and $65 for homes of varied sizes and systems.

However, it would help if you balanced this off with the savings you’d be making.

Because humidified air keeps heat better, you’ll be able to turn down the heat in your home during the cooler months.

You will save energy and money as a result of this.

How to Install a Whole House Humidifier?

Because there are so many types of whole-house humidifiers, the installation for each one will be unique.

As you might expect, if you choose a portable humidifier, you’ll be able to set it up yourself – after all, you’ll only have to transfer it to a room and plug it in.

On the other hand, the installation process will be significantly more difficult if your humidifier is utilized in conjunction with or is connected to your home’s heating system.

Not all of them will be too difficult for you to do, and you may be able to accomplish some of them yourself, but a substantial number of them will probably be better left to professionals.

How we evaluated

We offered a good balance of whole house humidifier alternatives in both free-standing and furnace-mounted models to effectively handle many home types and humidification needs.

We also considered overall quality, including devices from well-known brands we’ve come to trust, such as Honeywell and Aircare.
