1. AIRCARE MA1201 Review (Editors Choice)air care best whole house humidifier review

The number one spot on our best whole house humidifier review is the Aircare MA1201. This is is my number one pick because this humidifier can provide humidity to a whole house, up to 3600 square feet. Many other whole house humidifiers require installation in order to provide coverage up to 3600sq.  The Aircare is a console, simply plug it in and turn it on.

The Aircare features a digital humidistat to automatically maintain your desired humidity level with precision accuracy. To prevent excess humidity levels, the machine will shut off when desired levels are reached and when the unit is empty. The automatic shut off will prevent damage to the machine and adverse effects from high levels of humidity.

 This whole house humidifier can run up to 36 continuous hours with its 3.6-gallon tank. With the assembled dimensions of 20.5(h) x 21.5(w) x 14.5(l). 


 The downside to this product is the head rest height. Reviewers have commented that the head rest was shorter than they expected. For someone that is around 5″8, the head rest may be slightly below the head. 


Covers up to 3600 sqm
No installation
Large water tank
Great price
Filter costs may add up


For under $100, you can’t go wrong with this whole house humidifier. It is an excellent unit that covers a vast area without the need to install it to the home’s HVAC system. Many humidifiers in the same price range only cover room to room. While other whole house humidifiers that can cover the same amount of space, tend to cost twice if not three times as much.

2. Ultrasonic Cool Mist Humidifier XLReview (Best Sinultrasonic best whole house humidifier reviewgle Room)

The runner-up on our best whole house humidifier list is the Ultrasonic Cool Mist. This little unit is ideal for rooms up to 500sq. This is great for those who don’t need to cover large areas in their homes.

The Ultrasonic Cool Mist is much more eye appealing than the Aircare. It is also much smaller and can be placed on a table as decoration. With an optional night light feature, offering soothing light for maximum relaxation and providing attractive blue green or red light.

It holds up to 1-gallon of water, providing enough steam output to cover large bedrooms, offices and other rooms up to 500sq. Choosing between single and dual mist nozzle settings, providing long lasting relief from 10 to 24 hours depending on your settings.

With a built-in safety feature, turning off the humidifier when the water is low or when the tank is removed. There is no worrying of damaging your humidifier.

Product dimensions:  13.5″ x 13.5″ x 8.5″ 

Very Quiet

LED lights


I would strong recommend this product to those who don’t need to cover a large area with their humidifier. This humidifier is perfect for smaller houses and rooms that are used more frequently, like the bedroom and living room. The design and LED feature make this humidifier appealing. The Ultrasonic Cool Mist is tied for first place in the best whole house humidifier review.

3. Vornado Evap40 Review (Best for 1000SQ)vornado best whole house humidifier review

The Vornado Evapo40 is our middle pick for best whole house humidifier. It is covers significantly larger area than the Ultrasonic Cool Mist but less than the Aircare. Covering up to 1000sq, it would be a great choice for those who want more coverage than the Ultrasonic but less than the Aircare.

The Vornado features an automatic humidity control with a built-in humidity state. With three settings, allowing for perfect humidity levels of your choosing. Using two humidifying filters to circulate humidified air throughout the room.

With an extra large 4-gallon water tank, allowing long continuous operation with fewer water refills.

The product dimensions are  10.5″ x 19.5″ x 13.5″.   The downside to this product according to many reviewers is the weight of the humidifier once refilled. A simple solution is to fill a jug full of water and refill the humidifier where it is. This solution is much easier than carrying over a humidifier filled with water. 


Covers up to 1000 sqm
Large water tank
Well priced
Loud on high setting


I would highly recommend this humidifier for those who want something bigger than the Cool Mist and something smaller than the Aircare. Covering up to 1000sq is enough for the majority of users. The large water tank is also an excellent design feature. Forget about all the hassle when it comes to refilling it all the time.

4. Aprilaire 500 Review (Up to 3000SQ)Apailaire 500 best whole house humidifier reviews

This humidifier isn’t like the ones listed above. The Aprilaire requires installation to the home’s HVAC system. Installation directly to the home’s HVAC system can distribute humidity evenly throughout the house.

The Aprilaire will cover up to 3000 SQ with an evaporation rate of .5GPH.

 The downside to this product is the installation. It may require some technical skills or even a trained professional. Though after you set it up once, it will be hassle free. 


Doesn’t require filling water
Covers up to 3000 sqm
Evenly distributed humidity
Technical installation


This whole house humidifier is rated at number 4 because of the installation. If you are in an area where low humidity is constant, then I would strongly advise installing the Aprilaire. It will save you lots of time from having to replace filters and refilling water tanks on console models.

5. Aprilaire 700 Review (Up to 4200SQ)Aprilaire 700 best whole house humidifier reviews

Last on our best whole house air humidifier review is the Aprilaire 700 Automatic Humidifier. The reason for this being last on the list isn’t because it’s the worst. The Aprilaire 700 is a step up from the Aprilaire 500. This humidifier is capable of handling up to 4200SQ.




Doesn’t require filling of water
Covers up to 4200 sqm
Evenly distributed humidity
Technical installation



Often we opt for the simple method, which in this case would be the plugin console type of humidifier. If you are constantly in a low humidity setting, I would strongly suggest using a humidifier that installs to your home HVAC system. This will ensure the whole house will have proper levels of humidity, and not just single rooms. It also only requires maintenance once a year compared to the console systems where they should be looked at every few days.

Whole House Humidifier Buying Guide

As you can see from the reviews that there is no one size fits all when it comes to whole house humidifiers. Here are a few things to consider.

Space – How big is the area you intend to use your humidifier for? If you are only at home when you sleep then a small console unit like the Ultrasonic Cool Mist would be sufficient. If you intend to be in other areas of the house, consider getting the Aircare or Vornado. Getting a humidifier that covers a large area will save you time and effort from having to
move the humidifier from room to room. It is most important to have it where you sleep.

Location – Where do you live? What kind of climate do you have to deal with throughout the year? In places that are hot and dry like Arizona, you should consider getting an install type of whole house humidifier. Getting an install type is better suited for this situation because it distributes even humidity throughout the whole house.

Price – What is your budget that you have set out for your humidifier? Smaller console types are more budget friendly than install types if you have to pay for installation. Install types can be quite budget friendly if you can do the installation yourself. Paying for a professional can be pricey when it comes to HVAC installation.

Appeal – Does the look of the machine matter to you? Some of the consoles like the AirCare does not look very appealing. Whereas the Ultrasonic Cool Mist is very attractive. Take this into consideration before purchasing.

 My recommendation if you plan on using a humidifier year round is to opt for the install type (Aprilaire 500 or 700) depending on the size of your home. It will save you tons of hassle down the road compared to the console type.   General use for bigger homes I would pick the AirCare and the Vornado for homes up to 1000SQ.   General use for bigger homes I would pick the AirCare and the Vornado for homes up to 1000SQ. 

What is a Whole House Humidifier

A whole house humidifier is a device that increases humidity (moisture) to the entire house or building. These units can be connected to the home’s HVAC system to increase the humidity throughout the house. Or be placed in a single room to improve the room’s overall moisture.

How to Clean Humidifier

It is important to keep up with cleaning your humidifier. Each humidifier will have their own specific cleaning instructions. So be sure to follow the instructions according to the manual.

Here is a video on how to clean a humidifier. This should give you a general idea of the things you will need and the steps to take.

5 Benefits of Using a Humidifier

  1. Reduce risk of infections – Using a humidifier will lower chances of getting an infection, especially when it comes to the winter flu.
  2. Easing Asthma – Humidifiers are useful for those who suffer asthma. Many children and adults have reported their asthma conditions have improved with the use of humidifiers.
  3. Treats Cold, Flu, and Allergy Symptoms – Humidifiers add moisture in the air to fight against dryness, irritation in the nose and even eyes.
  4. Softer Skin – humidifiers can combat dryness in the winter by adding moisture in the air.
  5. Protecting Wood Furniture – The dry air in the winter time can cause damage to wooden furniture. Adding moisture will keep your furniture looking new.

Humidity and Temperature

Having a whole house humidifier is important especially in hot, dry climates and artificially heated spaces, especially during winter. During the winter seasons, the humidity may drop as low as 10-20%. Having little humidity can cause adverse health effects. Low humidity drys out mucous membranes in the nose and throat, causing respiratory distress. While low humidity is a factor, high humidity is a problem also.

While low humidity is a factor, high humidity is a problem also. High humidity can cause damage to wood and other household items. High humidity can also lead to the growth of dust mites and mold. And also have advert health effects.

Effects of Low Humidity

During the winter months, heaters and cold temperature can cause dry air and low humidity. Low humidity can cause dry skin, irritated sinuses, throat and even itchy eyes. When exposed to low humidity over time, the sinuses can dry out, leading to a risk of infections. Low humidity can also cause the eyes to dry out due to increased evaporation of tears.

Effects of High Humidity

We now know what little humidity can do, let’s discuss what high humidity can cause.

High humidity can help the growth of mildew, mold spores, and other harmful bacteria. Elevated levels of humidity can also have adverse effects on your home as well as your house. Mold and mildew can develop and seep into the walls of the house, compromising its structural integrity. It can also do the same to wood furniture in the house, making them much weaker.

To combat high humidity we can use devices called dehumidifier. This machine takes the moisture out of the air, unlike the humidifier; which adds moisture instead.

Types of Humidifiers

Central Humidifiers

Central humidifiers are built directly into the home’s air condition or heating system (HVAC System). These are generally the most expensive and require professional installation. This is the best choice when you want to add even humidity throughout the house.


These are the most common traditional type of humidifiers. They blow moisture through a moistened filter. The filter is used to trap mineral scale and reduce the risk of fine white/grayscale dust penetrating the room. These humidifiers are more affordable than central humidifiers, but the downside is they are limited to single rooms. The costs associated with changing the filters can also add up in the long run.

Cool Mist Impeller Humidifiers

These work like evaporators but do not require a filter. They are very budget friendly but are limited for use in small areas. Since the cool mist humidifiers don’t use filters, it requires distilled water. Using distilled water will prevent water impurities from depositing on surfaces around the humidifier. The impurity deposits resemble a fine white/gray dust or powder.

Ultrasonic Humidifiers

Ultrasonic humidifiers utilize an ultrasonic vibration to produce a cool mist. These humidifiers are often quieter than other humidifiers, and they do not use filters. Without the use of filters, impurity deposits may form around the room. These are also safer around children because the unit does not heat the water.

Steam Humidifiers

This type of humidifier is generally the cheapest. The unit boils the water, releasing steam into the air. This technology could be paired with a medicated inhalant to reduce coughing. Steam humidifiers can be dangerous to children due to the hot water in the unit.
