So, you already have a humidifier in your home. It’s great, you feel its benefits, and the whole family loves it. But, until when? It’s okay if everyone is in the living room all day, but what happens when it comes to bedtime? I’m pretty sure that your small, single humidifier will not cover the entire house.

On the other hand, you might have a few humidifiers plugged-in in each bedroom. If so, I bet you’re having a hard time cleaning and maintaining all those units! Well, maybe its time you get a humidifier than can cover the entire house.

Here’s our take on whole house humidifier pros and cons. Be sure to read the whole article before you make your decision!

Whole House Humidifier

Before we talk about the advantages and disadvantages of a whole house humidifier, it’s important to know how they work.

How Does It Work?

Whole house humidifiers work just like your portable humidifiers. The main difference is, of course, the area it covers. As the name suggests, they cover the entire home area.

They may or may not be installed directly into your HVAC system. Most models are installed right next to your furnace and will turn on automatically once your HVAC is turned on. They’re usually controlled with a humidistat.

Some are pedestal style humidifiers that are still portable but have a much larger coverage area.

What Does It Do?

Generally, whole house humidifiers emit water vapor or steam to increase moisture levels in the air.

Why Get One?

So, what are the benefits of installing a whole house humidifier?

Health and Comfort

Flu, colds, and allergies will be prevented. Cracked, itchy skin will also be kept at bay.


They are also good for wood floors, artworks, and instruments.

Wider Coverage Area

If you’re tired of taking care of a lot of small humidifiers, well, get a whole house type. Their coverage area goes up to 3,600 square feet! No need to bring your humidifier with you anywhere.

Automatic Humidity Control

Since we can’t see the humidity level physically, it’s a good thing that whole house humidifiers can automatically control it for us. Most models are equipped with humidistats that allow you to easily set your desired humidity level, which should be between 40% and 60%.

Low Maintenance

Whole house humidifiers that are installed with your HVAC are very easy to maintain. A replacement of the water panel once a year is all you need to do.

Less Likely Do-It-Yourself

You can save yourself from the hassle of installation since professionals will do it for you. Plus, no need to refill it every few hours since it’s linked directly to your plumbing.

Easy to Control Remotely

Most models come with a remote-control system so you can adjust the humidity without actually touching the unit.

Silent and Hidden Away

Usually, they are placed somewhere you don’t usually see, and you don’t need to worry about it producing any loud noise.

What Are the Downsides?

As with every product, whole house humidifiers also come with their downsides.

Mold and Mildew

If you fail to clean and maintain your whole house humidifiers regularly, molds will probably form inside it or in your HVAC system. When the furnace air filter is full of dust, plus the moisture is present all the time, molds can take root.


Whole house humidifiers cost more than portable ones. Plus, you need to pay for the installation.

Hiding HVAC Air Leaks

This appliance may cause a bigger problem of home air leaks to be unseen.

Difficulty Moving

Naturally, since you will install your whole house humidifiers in your HVAC, it’s not an easy task to move it if needed. Maybe you want to upgrade to a higher model or resell it; nevertheless, you need to do quite a lot of work to detach it.

Even pedestal type whole house humidifiers are hard to move and transport due to their weight.
