Here’s a fact that might scare you: Indoor air pollutant levels are typically 2 to 5 times greater than outdoor levels, according to the EPA.

That’s especially worrying when you consider the fact that the average American spends 90% of their time indoors. It’s no wonder that the EPA considers indoor air quality to be one of the five greatest environmental risks to public health. Some appliances such as portable air conditioners can change the natural air flow within your home.

Fortunately, some appliances can improve the quality of your indoor air, like whole house humidifiers.

Whole house humidifiers are devices that add moisture to the atmosphere indoors to create higher levels of humidity. They spread this humidity out evenly throughout your home. I’ll be covering everything else you need to know about these useful appliances throughout the article.

I’ll also be listing, reviewing, and comparing the best whole house humidifiers on the market so that you can get the right product for your home.

Styles of Whole House Humidifiers

We can broadly subcategorize whole house humidifiers into the following two different styles:

Furnace

Furnace humidifiers are appliances that integrate with your existing HVAC system, hence the name. The humidity that they generate is distributed evenly throughout your home via your HVAC system.

They typically have around 3 to 4 times greater humidity output than console humidifiers. They also have minimal maintenance requirements.

The downside to furnace humidifiers is that they’re usually more expensive and are much more complicated to install. You’ll probably need to pay for professional installation service.

Console

Console humidifiers, on the other hand, don’t integrate with your HVAC system. Instead, they’re standalone appliances that just need to be plugged in and turned on. However, this does limit its humidity output and distribution capabilities.

The humidity generated from a console humidifier can’t pass through your HVAC system so you’ll need to leave your doors open if you want it to spread throughout your home. Even then, at best, it will only be able to distribute humidity to the rooms on the same floor.

They’re usually cheaper to purchase and much easier to install than furnace humidifiers, but they also require a lot more maintenance.

Humidifier Types

We can further subcategorize humidifiers based on how they work. Here are the main different humidifier types you should know about:

Bypass

Bypass humidifiers are a type of furnace humidifier. They connect between your hot and cold air return ducts to push heated air through the humidifier as it passes through the ducts. As the heated air passes through the bypass, it’s used to create humidity.

There are different types of bypass systems, such as drum bypass systems and flow-through systems, but we won’t go into those just yet. Drum systems are the most popular. You can find more information on how these different systems work towards the bottom of this page.

Fan-Powered

Fan-powered humidifiers are similar to bypass systems but they also use a fan to pull hot air directly from the furnace and push it through the humidifier. The fan speeds up the evaporation process and these units can therefore usually produce more humidity per day than bypass humidifiers. As they don’t require a bypass duct, they also take up less space and can be installed in smaller areas such as bedrooms that babies are sleeping in.

Fan-powered can also refer to console units that use a fan to blow a cool mist into the air.

Steam

Steam humidifiers (also known as sometimes as ‘hot or warm mist humidifiers) also use heat to create humidity, but they don’t take it from your furnace. Instead, they generate their heat via electricity and use it to boil water.

As the water boils, it turns into steam. The humidifier then distributes that steam through your home/ductwork to create humidity. Filters in steam humidifiers also remove some of the allergens and pollutants from the air. Steam humidifiers tend to be the most powerful and can generate the highest humidity output.

Evaporative

Evaporative humidifiers are sometimes known as ‘cold or cool mist’ humidifiers. Unlike the types above, these humidifiers don’t use heat. Instead, they create humidity through evaporation via a wick, a water reservoir, and a fan.

The wick absorbs water from the reservoir, which then evaporates from across its surface area. There is also a fan to help distribute the water as it evaporates. The speed of evaporation will depend on the humidity of the room, which means that these types of humidifiers are self-regulating. Sometimes, flow-through bypass humidifiers are referred to as evaporative humidifiers.

Benefits of Having Humidifiers for the Home

There are many benefits of having a humidifier in your home, but here are some of the biggest ones:

  • Helps combat breathing issues and minimize the effects of allergies
  • Reduces respiratory-related health risks
  • Helps to prevent nosebleeds and asthma that may be triggered by dry air
  • Increases comfort
  • Stops wooden objects and furniture in your home from drying out and becoming damaged
  • Guards against mold and mildew

I could go on and on, but you get the picture!

Signs that Your Home Needs a Humidifier

You know you need a humidifier if:

  • Your plants are looking unhealthy/drooping
  • The wallpaper is curling upwards at the edges
  • You’re suffering from more frequent nosebleeds
  • Your lips and dry and cracked and/or have regular sinus problems
  • There’s a lot of static electricity buildup in your home
  • You’re more frequently having allergy symptoms, asthma attacks, or other respiratory problems

Buying Guide: Whole House Humidifiers

Before we get into the list of best whole house humidifiers, I’ve put together a brief buying guide. Here are some factors you should consider when shopping around for a humidifier:

Humidifier Type For Your Home

Think about what type of humidifier would work best for your home. For example, furnace humidifiers may be more suitable than console humidifiers for homes in super dry climates, especially if you plan on running your humidifier 24/7. Similarly, if you have kids, cool-mist humidifiers might be more suitable than steam humidifiers as they’re less dangerous.

Room Coverage/Capacity

Make sure to choose a humidifier capable of covering your whole home. Most models will tell you their coverage area in square feet, and this should match the size of your home as closely as possible. More coverage area isn’t necessarily better. If it’s much greater than the size of your home, you might end up with too much humidity (and mold!).

Setup & Installation

Portable/console humidifiers should be fairly easy to install. Furnace humidifiers that integrate with your HVAC system will be much more difficult. If you attempt to install the latter type yourself, you could potentially void your warranty. Think about whether you can afford the installation cost of the electrician when comparing humidifiers.

Daily Humidity Output

Different humidifiers have different humidity outputs. The humidity output is typically measured in ‘gallons per day.’ The humidity output you need will largely depend on three things:

  1. How dry your home/indoor climate is
  2. Your desired indoor humidity levels
  3. The size of your home

Generally speaking, for large households (3,000 sq. feet or more), you’ll need a humidifier with a humidity output of at least 9 gallons per day to bring your whole home up to a comfortable humidity level. You can use this tool to calculate your personalized daily humidity output requirements.

Weight and Dimensions

Consider the dimensions and weight of the humidifier before you buy it to make sure it will fit where you want to install it. If you’re purchasing a furnace humidifier, make sure the size and weight are suitable for your HVAC system.

System Compatibility

Some older homes have older furnace/HVAC systems that aren’t compatible with many types of humidifiers. Most furnace humidifiers rely on air ducts to distribute humidity, so they won’t work in any home that doesn’t have existing ductwork (like those that use radiators for central heating and cooling). Consider system compatibility carefully before you make your purchase.

Warranty

Make sure to check the warranty information of your humidifier too. Many products will come with a part warranty, typically for 5 years after the installation date, which covers you for a replacement of any defective parts within that period. Some humidifiers have shorter/more limited warranties than others, so check the small print!

Extra Features

Finally, look out for any additional features that improve the overall quality of the humidifier. For example, some water heaters come with fancy features like:

    • Timer
      This feature lets you set the times you want your whole home humidifier to run in advance
    • Overflow protection
      This is a safety feature that helps to stop the system from overheating/overflowing
    • Automation
      Some heaters can even actively monitor your home’s humidity levels and use this information to activate and correct dry spots automatically.

10 Best Whole House Humidifiers Reviewed

1. Aprilaire 400

Best Whole House Furnace Humidifier (Automatic)

Type Bypass (flow-through)
Water Tank Capacity N/A
Room Coverage 4,000 square feet
Daily Humidity Output 17 gallons per day
Dimensions 10.2 x 15.4 x 15.8 inches
Warranty 5 year part warranty

My number one pick for the overall best whole house furnace humidifier goes to the Aprilaire 400. Aprilaire is going to come up a few more times on this list as they’re the leading brand when it comes to making the best whole house furnace humidifiers.

Out of all of their products, I think that the 400 model offers the best value for money. It’s a bypass humidifier, so you’ll need to pay for a professional installation, but it’s definitely worth it.

“We used this Aprilaire 400M to replace a 40-year-old Aprilaire 550. The technology of this unit is impressive, and it should save a lot of water”, says one reviewer on Sylvane.

It works on a flow-through system in which dry, warm air is passed through the HVAC bypass and pushed through water panel to evaporate it and create humidity. It can cover up to 4,000 square feet and generate up to 17 gallons of water per day, which should be plenty enough for medium to large households.

One thing I love about this unit is that it’s automatic. The dual sensors monitor the humidity levels so that you don’t have to. It will automatically maintain a humidity level of 35 – 45%, which is right in the sweet spot.

Little maintenance required, but you will need to replace the water panel evaporator annually, so I’d recommend pairing your purchase with a water panel evaporator pack.

Pros

  • Conserves water
  • Automatic humidity sensors
  • No drain required
  • Easy maintenance
  • Great value for money

Cons

  • Complicated installation (requires professional)
  • Not as powerful as fan-assisted or steam models

2. Aprilaire 700M

Best Whole House Furnace Humidifier (Fan Powered)

Type Fan powered
Water Tank Capacity N/A
Room Coverage 4,200 Square feet
Daily Humidity Output 18 gallons per day
Dimensions 10.3 x 15.9 x 18 inches
Warranty 1 year part warranty

Next up we have the Aprilaire 700M – the best whole house furnace humidifier (Fan Powered). It’s very similar to the 400 above but with a few important differences.

Firstly, as this unit is fan powered, it doesn’t require any extra bypass ductwork as it won’t be using your furnace’s blower motor to push air through the system. Instead, it takes care of this itself using the in-built fan.

This makes it a little pricier, but it also comes with a lot of extra benefits.  HVAC summarized these benefits nicely in the quote below:

“Fan-powered humidifiers moisturize the air and distribute it directly to the home, preventing humidity loss. These units are capable of producing around one gallon more humidity each day than a bypass humidifier. They have the power to add moisture across a larger square footage, making a fan humidifier an ideal choice for larger spaces.”

Secondly, it’s a manual humidifier, so you’ll have to set the humidity level yourself. However, it does have a sensor to show you the current relative indoor humidity levels.

Pros

  • Fan powered increases output
  • No bypass required
  • Good value for money
  • Good room coverage

Cons

  • Manual humidifier
  • Short warranty period

3. Aprilaire 800

Best Whole House Steam Humidifier (with Air Ducts)

Type Steam
Water Tank Capacity N/A
Room Coverage 6,200 Square feet
Daily Humidity Output 34.6 gallons per day
Dimensions 7.1 x 10.1 x 20.9 inches
Warranty 5 year part warranty

Moving on to the Aprilaire 800, the overall best whole house steam humidifier (with air ducts). The first thing to mention here is that this model is super powerful. As it’s a steam humidifier, it’s able to create moisture and distribute it around your home much more effectively than other types of humidifiers.

It has a whopping room coverage of 6,200 square feet and can generate almost 35 gallons of water per day. That makes it suitable for substantial households and homes in arid, desert climates where the air is very dry. Despite all that power, it’s surprisingly quiet.

“The unit makes no noise other than the water and drain solenoids opening and closing.”Supplyhouse review

The only problem is all that water means it wastes a lot of it, so if water preservation is a priority, it might not be the way to go. However, the good news is that you can use regular old tap water and don’t need to use purified water. In fact, purified water is not recommended as the technology needs those minerals to be present to properly transfer electricity to the water.

Pros

  • Ideal for the driest climates
  • Superb room coverage and humidity output
  • No need for distilled water
  • Maintains optimal humidity levels for health

Cons

  • A lot of water wastage
  • Requires air ducts

4. Aprilaire 865

Best Whole House Steam Humidifier (without Air Ducts)

Type Steam
Water Tank Capacity N/A
Room Coverage 6,200 Square feet
Daily Humidity Output 34.6 gallons per day
Dimensions 7.1 x 10.1 x 20.9 inches
Warranty N/A

The Aprilaire 865 is essentially the same model as the 800, but with one important difference: it doesn’t use air ducts. It’s another steam humidifier that boils water and distributes the steam throughout your home, but the method of distribution is a little different. Instead of pushing the steam directly into your air ducts, the wall mount fan distributes it throughout your living space.

This is perfect for houses in very dry climates that don’t have a duct system or want something easier and quicker to install. It covers up to 6,200 square feet, and you can set the humidity output at any of 6 levels ranging from 11.5 gallons to 34.6 gallons depending on your requirements.

It’s much easier to install than the Aprilaire 800 as you’ll need to perform a straightforward water supply connection and hook up a circuit. However, I’d still recommend hiring a professional over doing it yourself, especially if you don’t have any electrical knowledge.

Pros

  • Easier to install
  • No ductwork required
  • Huge room coverage
  • Great daily humidity output

Cons

  • Wastes a lot of water
  • Doesn’t distribute moisture as effectively as it would via a duct system

5. Aprilaire 500

Compact Whole House Humidifier for Hard Water

Type Bypass
Water Tank Capacity N/A
Room Coverage 3,000 Square feet
Daily Humidity Output 12 gallons per day
Dimensions 10.2 x 15.6 x 13 inches
Warranty 1-year part warranty

Last up we have the Aprilaire 500, the final Aprilaire product on this list and the best compact whole house humidifier for home use. It’s relatively compact so that it will take up less floor/wall space. However, you can’t install it on the wall in your living area as airflow needs to be able to reach the humidity sensors for accurate humidity recording.

It works with hard water, which is great if you’re in an area where the water supply has high mineral content. It has a respectable 3,000 coverage area which is enough for small to medium sized homes and a humidity output of 12 gallons per day.

It can be difficult to install unless you’re a qualified professional and will take at least 3 or 4 hours but, once it’s up and running, it works like a charm. I like the fact that it offers automatic humidity control and comes with a digital control that allows you to easily see when you need to perform some basic maintenance tasks.

Pros

  • Compact design
  • Automatic humidity control
  • Digital control for easy maintenance checks
  • Works with hard water

Cons

  • Short warranty period
  • Difficult to install

6. URPOWER

Quietest Whole House Humidifier

Type Ultrasonic
Water Tank Capacity 5L
Room Coverage up to 300 sq.ft.
Daily Humidity Output 2.5 gallons per day (approx)
Dimensions 16.8 x 10.1 x 7.3 inches
Warranty N/A

Unlike the units we’ve looked at so far, this humidifier from URPOWER is a console humidifier, which means it’s a standalone appliance that doesn’t need to integrate with an HVAC system. It’s much easier and quicker to set up.

It’s also the best quiet whole house humidifier on the market, thanks to the fact that it doesn’t have a fan or any noisy parts.

“The mist is almost immediately absorbed into the air. Because this type of humidifier does not use a fan, it is very quiet when operating” – Guardian Technologies

It’s also the best whole house ultrasonic humidifier we could find. Ultrasonic humidifiers are another type of unit that we haven’t talked about yet. They work by emitting high-frequency vibrations to break up the water into a very fine mist before expelling it into the room.

It doesn’t have a vast humidity output or coverage area, so it’s best for small apartments or single rooms. I also like the fact that it comes with some great additional features, like a ‘sleep mode’ button that turns off the lights and an automatic shut off function.

Pros

  • Easy to operate
  • Stylish design
  • Silent operation
  • Cool extra features

Cons

  • Humidity output fairly low
  • Not great at distributing humidity throughout the home  

7. AIRCARE MA1201

Best Evaporative Whole House Humidifier

Type Evaporative
Water Tank Capacity 13.6L (approx)
Room Coverage 3,600 Square feet
Daily Humidity Output N/A
Dimensions 14.5 x 21.5 x 20.5 inches
Warranty 2-year part warranty

The AIRCARE MA1201 is my top pick for the best evaporative whole house humidifier, at least when it comes to console units. The fact that it’s an evaporative humidifier means it works by moving dry air through a wet wick filter to naturally release that moisture into the air.

It runs automatically, all you need to do is set your desired humidity level, and the unit will do the rest. Once the humidity level in your home has reached the correct level, the unit automatically shuts off. I also appreciate how easy this unit is to clean. The wick traps the mineral deposits, so you don’t need to worry about white dust. It’s simple and easy to operate.

It’s also on wheels, so it’s easy to roll around from room to room. If you leave your doors open, it should be able to humidify the whole house. The room coverage is 3,600 square feet, so if you’re in a modestly-sized home, it should be plenty!

Pros

  • Easy to operate
  • Mobile and compact
  • Quiet
  • Reasonably good coverage area

Cons

  • Short warranty period
  • Works best with doors left open to aid distribution

8. Honeywell Cool Moisture Console

Best Cool Mist Humidifier

Type Fan powered
Water Tank Capacity 11.3L (approx.)
Room Coverage 2,300 square feet
Daily Humidity Output N/A
Dimensions 23.1 x 15 x 17.5 inches
Warranty 3-year part warranty

The Honeywell cool moisture console humidifier is, without a doubt, one of the best whole house cool mist humidifiers on the market. Like the unit above, it works on evaporative technology. This is safer for two reasons:

  1. You don’t have to worry about making the room too humid as moisture will only evaporate when the moisture content in the air is below a certain threshold, so it self-regulates
  2. It emits a cool mist, which is safer for use around children – there’s no boiling water involved.

The wick also removes impurities from the water as it passes through so you don’t have to worry about white dust. The unit is easy to use and can be set up as a standalone unit. The automatic shut off feature means you don’t have to worry about it overheating, and the dual water tanks are straightforward to clean.

I’d recommend this humidifier for small homes or apartments, especially if you have children.

Pros

  • Large water tank
  • Easy maintenance and cleaning
  • Straightforward set up and use
  • Self-regulating evaporative humidifier

Cons

  • Room coverage fairly low

9. AIRCARE EP9 800

Best Pedestal Style Humidifier

Type Evaporative
Water Tank Capacity 13.2L (approx)
Room Coverage 2,400 Square feet
Daily Humidity Output N/A
Dimensions 18 x 18 x 27.2 inches
Warranty 2-year limited warranty

The EP9 800 evaporative humidifier from Aircare is the beset pedestal-style whole house humidifier I’ve come across. Unlike the humidifier above, it doesn’t have wheels and looks more like a decorative piece of furniture.

Users have claimed that it can easily last for 2 + years with regular cleaning and care. It’s a large, heavy-duty unit that looks at home in a stylish, modern interior. The large, flat surface on top means it can even double up as a table or a display unit.

It’s not all about looks though; it works well too. It has an estimated room coverage of around 2,400 square feet. To be entirely honest, that might be a little optimistic, and I’d say it’s probably better in smaller homes or apartments. I’d recommend putting it in the room you spend most of your time in as it will be most useful there.

Pros

  • Elegant design
  • Automatic unit
  • Useful digital display
  • Automatic shut off feature

Cons

  • Limited room coverage and distribution
  • Not very portable

10. hOmeLabs (9-Pint & Energy Star)

Best Whole House Humidifier for Allergies

Type N/A
Water Tank Capacity 6L
Room Coverage 4,000 Square feet
Daily Humidity Output 9 gallons per day
Dimensions 15.4 x 11 x 24.3 inches
Warranty 2-year limited warranty

Finally, I wanted to finish up with this hOmeLabs dehumidifier. Yep, that’s right; it’s not a humidifier – it’s a dehumidifier. Rather than putting moisture into the air, this takes it out of it.

“no matter how many houseplants you have in your home or air purifiers running, it is impossible to keep your quality of air in your home at a healthy level if there is too much humidity”Allergy & Air

It’s a useful thing to have if you live in a very humid, sub-tropical climate. Ideally, the humidity within your home should be no more than 50%, so if it’s higher than that, it might be worth investing in a dehumidifier like this.

It has a room coverage of 4,000 square feet, so it can maintain the right humidity levels in large rooms and damp basements, and can remove up to 9 gallons per day, which should be plenty!

Pros

  • Good room coverage
  • Helps limit humidity levels
  • Stylish minimalist look
  • Helps eliminate odor

Cons

  • Can’t increase humidity levels  

Negative Impact of Dry Air

Dry air doesn’t just affect how comfortable you are; it affects your health too. Breathing in dry air all day at home can have some pretty bad adverse effects on the body, including:

  • Respiratory ailments (asthma, bronchitis, sinusitis, etc.)
  • Dehydration
  • Skin irritation and itchy eyes caused by dry eyes and skin
  • Static electricity
  • Nosebleeds

It also puts you at greater risk of contracting coughs, colds, and other viral infections.

It’s not just you that dry air impacts either, it’s your home too. Dry internal climates can cause the wood in your home to dry out, your wallpaper to start peeling, and your furniture to become damaged.

Whole House Humidifiers Working Systems

There are three different types of working systems used in whole house humidifiers. Here’s how each of them works.

Drum System

Drum systems are used in bypass humidifiers. In drum systems, a reservoir of water is attached to the furnace. Water is supplied via a pipe, and the water level is controlled by the float valve. A foam pad is mounted on top of a drum, which is then attached to a small motor.

Hot air travels through the bypass and into the drum on one side before leaving through the sides. The motor rotates the drum through the reservoir of water to prevent the foam pad from drying out.

Flow Through

Flow-through systems are another type of system used in bypass humidifiers. Unlike drum systems, flow through systems don’t require a reservoir of water. Instead, a pipe brings water directly to a valve on top of the unit. Air is passed via the bypass through an aluminum pad coated in matte ceramic.

To create humidity, the valve opens up and sprays water onto the aluminum pad. As the hot air passes through, the water on the pad evaporates and passes through the duct system to the rest of the house.

Spray Mist

Spray mist systems are a little more straight forward. A pipe brings water to the unit’s valve. To create humidity, the valve opens up, and the ‘atomizer’ forces the water to travel through a tiny space, which breaks it up into a fine mist. This water mist is then sprayed into the supply air and travels throughout the home.

Best Location to Put Humidifiers

Naturally, furnace humidifiers don’t leave you a lot of choices when it comes to the installation location. They have to integrate directly with your HVAC system, so the manufacturer’s instructions will specify exactly where they need to be installed.

Console units, on the other hand, can be installed pretty much anywhere. Most people prefer to put the humidifier in a central location in their home, like the staircase, so that the moisture can spread quickly throughout the premises. Others choose to put it where they spend the most time, like their living room or bedroom.

There are, however, two tips that you should stick to when deciding where to put it.

  1. Don’t put it on anything made of wood as it can wreak havoc with the moisture content and cause it to go out of shape
  2. Don’t put a warm-mist humidifier near your bed as it’s a potential safety hazard. Cool-mist humidifiers are fine.

DIY Guide to Installing Whole Home Furnace Humidifiers

I wouldn’t recommend trying to install a furnace humidifier yourself. This would be putting yourself and your home at risk. Instead, I’d advise you to hire a qualified contractor to install it for you as it requires professional electrical and plumbing knowledge.

Portable and console models can likely be installed following the manufacturer’s instructions. If you want to give it a shot, you’ll need some tools, such as:

    • A drill and drill bits
    • Marker
    • Wire strippers & nuts
    • Screws and screwdrivers that fit them
    • A wrench
    • Vent pipe
    • The humidifier
    • Aviation Snips

Here’s a video that walks you through the installation process for one model of a whole-home humidifier.

Care and Maintenance of Humidifiers

It’s important to regularly clean and maintain your humidifier. If you don’t, your unit can become a breeding ground for mold and nasty bacteria. It could also become clogged up, which will directly affect the performance of the unit and increase energy output.

Here are some whole house humidifier maintenance tips:

  • If your humidifier has a tank, replace the water in it daily and discard of any stagnant water
  • Rinse out the water tank daily, or as often as possible
  • Cleanse the humidifier unit once a week with diluted vinegar
  • Replace your wick filters every couple of months (2 to 4).

Note: always consult the maintenance instructions from your specific manufacturer

Frequently Asked Questions

How often should I change my humidifier filter?

Typically, humidifier wick filters will last up to 3 months, but I’d recommend changing it every 2 months if you use it frequently.

How often should I change the water in my humidifier?

You should try to change the water in your humidifier at least once a day to make sure the mist stays clean.

Can I use tap water in my humidifier?

You can use tap water, but I’d advise you against it. Tap water contains minerals that can build up inside your humidifier and shorten the lifespan of the filter. It’s much better to use distilled water.

What is the ideal humidity level for my home?

According to the EPA, the humidity level in your home should ideally be between 30% and 50%. This is a comfortable level of humidity in which spores can’t grow.

What is the white dust collecting in the humidifier?

White dust usually means there’s a buildup of mineral content in your humidifier. It often happens if you’re using a non-distilled water supply like tap water.

How much does it cost to have a whole house humidifier installed professionally?

Installation costs range from around $400 to $750. In some cases, it can be as high as $1000. It depends on things like the type of humidifier, your HVAC system, and the location you live in.

How do you size a humidifier for your home?

Here’s a video that walks you through the whole process. Consult the chart on the video to size your humidifier.

Is it safe to leave a humidifier on all night?

Generally, yes, it’s safe. It’s also usually a good idea as it will help to keep the indoor air quality top notch and help you to sleep better. This can also help those who suffer from dry skin because they can receive a ‘facial’ during the night.

Which is better, cool mist or warm mist?

Neither is definitively better than the other, but each has its pros and cons. For example, cool mist humidifiers may be safer, while warm mist humidifiers disperse fewer minerals into the air.

Where is a good place to buy these units?

You can purchase these units from Amazon and have them delivered to your doorstep. Alternatively, you can also buy them directly from the brand website, as well as other online and offline appliance stores.

Conclusion

Ok, that’s all you need to know about the best whole house humidifiers. Have you tried any of the units we recommended on this list? What did you think of them? Let us know in the comments!

If you haven’t made up your mind about which humidifier you want to buy yet, I’d recommend that you go for the Aprilaire 400. It’s the overall best whole-home humidifier on the market and will do the job without breaking the bank.

Good luck with the installation, and enjoy that healthy air!
