Top 11 Best Whole House Humidifiers Reviews of 2021

Thanks to its traditional design, the New Essick Air Ep9800 Digital Whole House Evaporative Humidifier is a whole house humidifier that you can use as a piece of furniture and keep out in plain view. The pedestal design makes it look like any other pedestal that you might use to display artwork or like a small table, and even if you tuck it into a corner of a room, it provides enough humidity for your entire house. Designed for use in homes of up to 2,500 square feet, it also works effectively in homes with a second story.

A built-in fan has nine different fan settings that you can select from based on the amount of humidity that you want, and it has a digital design that you can automatically control. When you select the humidity level you want, the humidifier will automatically turn off when it hits that setting to save on your energy bills. A digital read out on the humidifier shows you the current level and helps you more accurately keep track of the moisture in your home.

PROS:

  • Low maintenance
  • Cost-effective
  • Easy to operates

This Emerson HSP2000 Whole House Steam Humidifier is part of the White & Rodgers Comfort Plus line, which lets you know that it will increase your comfort while also adding to the moisture level in your home. The 120-volt humidifier has a filter that removes toxins like allergens and pollutants from your home’s air supply before releasing cleaner air and steam back out, and its humidistat constantly monitors the air and kicks on when it notices that the air is too dry. You can use this humidifier without waiting for your furnace to come on too.

Suitable for use in both residential homes and commercial businesses, this humidifier will only work if there is a minimum of 1,400 square feet in that property. It features a flushing timer that you can set for automatically flushing the system to remove old water and a humidity knob that lets you select the amount of humidity you want in your home.

Lennox has a great reputation for making quality parts and supplies, which is why its Y2786 Whole House Humidifier ranks so highly on our list, and while you can use this as a replacement part in your HVAC system, you can also install it separately to use that system to get the humidity that you need. Similar to a bypass humidifier, it connects to the furnace and uses the heat from that furnace to turn water into the steam necessary for increasing humidity levels, but it can do this without increasing the temperature of your home. It can also work with existing fans or blowers to push more of that steam away from the unit itself.

With a maximum daily output of 17 gallons of water per day, it uses under one gallon of water every hour but releases enough steam to bring down the humidity level in home with more than 2,000 square feet of space. Capable of reducing contaminants in your air, it has built-in filters that remove dust and other allergens to improve your overall air quality.

PROS:

  • Can install it separately
  • Has built-in filters 
  • Only 17 Gallons Per Day

SPECS:

  • 24 Volts, 60 Hz, 0.5 Amps

The Aprilaire 400 Humidifier Bypass comes with a digital control that lets you select the amount of humidity needed down to an exact figure, but you can also use a knob on the bottom to change the humidity from a low level up to a maximum level. As an evaporating model, it increases the temperature of the water, which turns it into steam and then releases that steam into your home. The Aprilaire 400 can add humidity to homes of up to 4,000 square feet in size.

With an evaporation rate of 0.7 gallons of water per hour, it slowly pumps out that steam based on your settings to make every room in your house feel just as comfortable as the next while also regulating the amount of water used to prevent waste. Though it requires less maintenance than other humidifiers, it does ask that you check the filter every 500 hours, and you may need to check it more often when you use it regularly. The Aprilaire 400 can also reduce your home’s temperature to make rooms feel cooler.

PROS:

  • Conserves water
  • Automatic system
  • Easy to install and affordable price

SPECS:

  • 8.8 pounds
  • 16 x 11 x 16 inches

Though similar to the Aprilaire 400, the Honeywell Whole House Bypass Humidifier (HE280) functions like a bypass humidifier and can install quickly onto your existing HVAC system to increase the humidity available. Once installed, it uses the heat from your furnace and the blowers on the whole system to transform water into steam and then to push those vapors through your home. Honeywell includes an installation kit for those who want to install it themselves without paying a contractor.

Unlike portable units and pedestal units that often require a lot of maintenance, Honeywell lets you use this one without doing much maintenance but does recommend that you check the filter and make sure the unit is clean and working properly every few weeks. One benefit of installing the Honeywell Whole House Bypass Humidifier (HE280) is that it begins operating so quickly and can starting adding more humidity to your home as soon as you install it and turn it on. It comes with a humidistat inside that regulates the humidity level and tells the humidifier when to kick on based on your preferences.

Its pedestal design has a convenient shape that you can use in any room, and its rich nutmeg finish has a classic look that can add a hint of style too. A front fill makes it easier to fill the tank and lets you add more water when needed without struggling or even moving the humidifier.

A fan inside produces the water vapors and has nine speed settings, which you can use to add more or less moisture into the air based on your preferences or the temperature inside. As part of the AIRCARE Home Decor Series, it comes with a small decorative tile that you can put on top to make a base suitable for a plant or piece of art.

Bypass humidifiers like this Aprilaire 600M Whole House Humidifier with Manual Controls essentially act like a bypass switch on your furnace or HVAC system to use the energy of that system to produce the vapors needed to increase humidity levels. The Aprilaire 600M is a 24-volt humidifier that has a digital control you can set up to use different automatic settings. The handle acts like a damper handle and gives you more control over the damper, which determines the amount of steam/vapors produced.

As water moves through the humidifier, it increases the temperature high enough that the water turns to steam, and you can adjust it to use up to three gallons of water every hour to make your home feel milder and cooler. When turned to its lowest setting, the 600M can use just 0.7 gallons of water per hour, which may be all you need on cooler or wetter days.

The AIRCARE 696 400HB Digital Whole House Console Style Evaporative Humidifier has the type of vintage look that might remind you of the console stereo or television your parents had when you were a child, but the inside of this console features a strong and effective humidifier. Its digital read out, which sits on the outside of the console, shows you the humidity level you selected, the current level and the speed of the fan. You can select from nine different fan speeds to cope with the current moisture level.

Two water bottles inside cut down on the number of times you need to fill the humidifier, and AIRCARE gives you a refill hose to make filling each one easier. The 696 400HB will shut off after reaching the humidity level you set or when both tanks are empty to keep itself from overheating.

Also from AIRCARE is the HD1409 Digital Whole House Console Style Evaporative Humidifier, which has a more modern design that incorporates a black finish on the console itself. When humidity levels climb high enough, the moisture in the air can actually kill spores and bacteria that might make your family sick, and the HD1409 can increase your home’s humidity to the proper level to kill those germs. It features casters on the bottom for moving the humidifier to different spots in one room or for use in a different room, and it can provide enough coverage for homes of up to 4,000 square feet in size.

Customizable settings let you pick the maximum amount of humidity level you want, and when it reaches this level, it automatically shuts down. Lights on the outside come on when you need to replace the filter or when the two water tanks need filled, and those tanks can hold five gallons to make the humidifier run for up to 55 hours.

As it uses an evaporative system, it won’t produce any of the dust that other humidifiers do.

Suitable for use in homes of up to 3,700 square feet in size, it comes with a single tank that fits inside and holds more than five gallons, and you can remove this tank for filling in your tub or sink.

This model uses wicks inside and has a 5.4-gallon water tank that you can refill easily when needed, and the humidifier has a maximum output of almost 12 gallons of water per day.

Our winner:

A whole house humidifier can increase your comfort level and make your house feel more inviting, but we think that the Emerson HSP2000 Whole House Humidifier does a better job of increasing the moisture levels of your home than any other humidifier. Designed for use with your existing AC or HVAC system, the best whole house humidifier uses steam to add more moisture to every room in your home, and it will only work in homes that are 1,400 square feet or larger.

As an energy-efficient system, it uses less energy and also reduces its output to help protect the environment. A flushing timer automatically flushes the system when needed to keep the steam produced fresh, and it can put out up to 13 gallons of water daily.


Whole House Humidifier Buying Guide

Warm vs. Cool Mist

A warm mist whole house humidifier boils water until it produces steam and then pushes that steam through your whole home. Filters inside pull some of the allergens from the air, but you’ll need to change those filters fairly often. As the outside can reach a high temperature, warm mist models aren’t suitable for use around kids.

Another option is a cool mist humidifier, which you can safely use around pets and kids. These can use a disc, a wick or another component inside that cools the water and releases water vapors back into your home. Most are fairly affordable too.

Capacity

You can pick up a standard humidifier from nearly any store that will work for a single room, but with whole house units, you need to consider the overall capacity. Larger models work well in rooms and homes of up to 999 square feet and are great for use in apartments. Always measure the square footage of your home and find a humidifier with a capacity that can fit the space.

Maintenance

With standard humidifiers, you need to empty the water reservoir and replace it with fresh water at least once a week and change the filter too. Whole house units can work with your home’s central AC system and will require less maintenance. You still need to get an idea of how quickly you can access that unit to make repairs or check the filter.

Installation

Find out easily you can install that humidifier too and whether you need help from a licensed contractor. Those that work with the AC system often require professional installation, and if you do the installation yourself, you might void your warranty. Professional installation can add more to the total cost of the unit too.

Output

Whole house humidifiers feature a design that releases fresh air and more moisture into all areas of your home, but if you pick one with the wrong output, you may not get the relief that you want. For homes of 3,000 square feet or more, you need a humidifier with an output of nine or more gallons of water every day.

Timer

Think about buying a humidifier with a timer feature, especially if you work or spend a lot of time away from home. This feature will let you tell the best whole house humidifier when to kick on and when to shut down, which can save on your power bills and still increase the moisture in your home’s environment.

Overflow Protection

Humidifiers that come with some type of overflow protection are good for most homes. This feature automatically turns the humidifier off when the water level in the dedicated reservoir drops too low or too high, which keeps the humidifier from overheating and stops the tank from overflowing.

Automatic Settings

You may prefer the best whole house humidifier that comes with some automatic settings too. These models can monitor your home for dry spots and produce water vapors or steam based on those dryness levels or on the temperature of your home.
