Helpful Tips: Where to Place Humidifier (+Complete Installation Guide)

Don’t know where to place humidifier at home? Don’t worry. We’re here to teach everything related to the air humidifier and how you can adequately place it.

Simply locating it on top of the table might seem like the way to go for this simple unit.

However, there are quite a few things you must take into account before placing the humidifier.

Once you’ve once gone through all the main points you should keep in mind, you’ll know exactly where to place this unit to get the most out of it.

Why Install a Humidifier at Home?

Ever noticed how the heat dries the air so bad to the point your family wakes up in the middle of the night feeling sick? Yeah, we’ve been there.

But if you’re not sure whether this device would make your life easier, we’ve got a couple of reasons that’ll change your mind.

Low Humidity

As you might already know, humidity is always is subject to change. For example, depending on how much moisture there is in the air, your skin could be affected.

You could get dehydrated, which will affect your mouth, and your eyes won’t produce any tears.

All these side-effects are caused by the lack of moisture in the air.

This problem can be fixed by using a humidifier. It will ensure to produce enough moisture to make up for it.

High Humidity

You know how the saying goes: excess of everything is unhealthy. And this holds true even with moisture.

As explained earlier, the humidifier has a simple job: to regulate the air’s humidity levels, even for high-humidity levels.

As opposed to low-moisture levels, high-moisture levels make you sweat a lot. This is why sweat tends to stay longer on your skin.

In addition to that, high-humidity levels can cause mold and even dust mites to appear all over the place.

Since the humidifier regulates the air, you wouldn’t have to worry about all these harmful contaminants.

Wood Shrinkage

The third benefit of having a humidifier at home is that you don’t need to worry about wood shrinking overnight.

Manufacturers tend to use industrial humidifiers when a specific humidity level must be preserved.

They’d be losing a lot of money if their wood were to shrink.

Of course, you don’t need a high-end industrial humidifier to preserve your piece of wood.

A simple humidifier is more than enough to prevent moisture from warping and shrinking the wood.

Ease Of Use

Increasing humidity in a dry house can be tedious, and conventional methods just don’t cut it.

Boiling water, leaving the bathroom door open, and even hanging your laundry indoors take too much time for the average person.

The air humidifier makes this process a lot easier as it only needs water to regulate the air.

Once you’ve filled up the tank, which the unit comes with, you need to press a button, and the water will flow out of the humidifier.

Feeling Well Rested

Dry air can make snoring a lot worse. If you have a partner who snores too loud to the point you can’t sleep in the same room, you probably know this pretty well.

Adding a humidifier to your place would significantly reduce the snoring at night, and you’ll feel well-rested when you wake up.

Where to Place a Humidifier at Home?

Humidifiers are quite efficient when appropriately placed. Otherwise, you won’t get much out of it. As such, here are some recommendations:

Watch Out For Wooden Surfaces

You might feel it might be beneficial to place the humidifier on top of a wooden surface.

And you’re not wrong. It is probably the humidifier best location for the air to flow through the bedroom.

However, here is the thing: it might damage the surface that it’s sitting on, and this can get even worse when it is running overnight.

As such, put it on top of the wooden surface, but with a towel or protective cover between.

This will keep the wooden surface from getting damaged with the humidity.

It may seem unnecessary at first glance, but it’ll change your mind as soon as you notice how much water it spills out.

Place It Away From Your Bed

There is some stigma around humidifiers since they can be harmful to you if they’re not far away from you.

However, this is only true if the unit has never been cleaned before. It has a filter, which you must clean from time to time.

If you never cleaned it before, you’ll notice how much airborne the filter has caught once you pull it out.

Running such a dirty device while you’re trying to get some sleep might make you sick.

On top of that, some air humidifiers can make some noise. While the noise might not be too noticeable for some people, some would argue otherwise.

Place It Where You Need It

So, where to put a humidifier? Once you’ve understood the previous points, you only need to ask yourself just where you spend a lot of time.

For example, the living room would be a great place since you probably spend quite a bit of time there.

As long as you place it far away and cover the surface where the humidifier is on, you should be fine.

How to Install a Humidifier?

Here, you’ll learn how to install a humidifier. We’ll walk you through every single step needed to install a humidifier at home on your own. That said, follow these steps:

1. What You Will Need

Here are the tools you will need throughout the whole process:

  • A hammer, a flathead screwdriver, and a tin snip—to install the humidifier, you must cut the ductwork. Using these tools will make the job a lot easier.
  • A drill—to mount the control panel on the ductwork, you need a drill.
  • A magic sharpie—using a sharpie will help you determine where you need to cut to install the humidifier.
  • Tape—use tape to mount the template for the humidifier on the ductwork.
  • Caulk—when installing the frame, use caulk to properly seal it.

2. Put Up The Template On The Ductwork

Where to place humidifier? You must install it on the ductwork.

The first thing to you’re going to need to install the humidifier is the template. Use tape to secure the template against the wall.

After that, take your magic sharpie and then outline the template. This will tell you where you need to cut. Next, remove the template from the wall.

Keep in mind that this template is where you’ll make a hole. If your unit did not come with it, you could measure the humidifier and then outline it.

3. Cut The Ductwork

Once you’ve drawn the line on the ductwork, you have to cut it out. So, take the flathead screwdriver and hold it against the sheet metal.

As you’re holding it, please tilt it towards the bottom. This will allow you to cut through the metal as you use the hammer.

Next, grab the hammer and hit the screwdriver. Keep doing this until the cut is long enough for the tin snip to cut through.

From there, begin cutting. We suggest getting to the corner of the line as you’ll have a much easier time cutting the ductwork.

Now keep doing this until you’ve cut around the corner.

4. Install The Frame

Now that we have space for the humidifier to go in, mount the frame. Make sure to tighten the little tabs on the back of the frame.

Once you’ve mounted it, seal it. To do this, run a bead of caulk around the frame.

5. Insert The Water Panel

Before installing the water panel into the frame, make sure the drain side is facing down.

As you’re installing it, you should hear a clicking sound, which means you got it right.

After that, connect the water feed tube to the water panel. Next, put the cover back on.

6. Connect The Lines

Once you’ve successfully installed the water panel, you must connect the water line to the valve, which can be found on the bottom.

Don’t forget that humidifiers need water to work. Next, connect the drain hose to the drain side of the unit.

Now you’re only left with the lead wires. These wires must run back through the control and the transformer for the unit.

And they should run back to the system. With that out the way, plug the humidifier into the outlet.

7. Install The Sensor

Now, here things can get pretty messy since there’s a lot to do. First, you must install the control panel into the ductwork on the return side.

For this, you’re going to make a hole using the drill for the control to fit it.

Depending on your unit, the hole might be bigger or smaller. In our case, we’ll go with a ¾ inch hole.

But before you can put the sensor into the hole, you must remove the dial and the cover. After that, install the sensor.

The screw holes should now be exposed. So, go ahead and secure the control with the screws.

8. Configure The Water Panel

We’re not done just yet. We still need to set up the control panel.

On the control panel, you should see the water panel. It looks just like a small circle and has a couple of letters.

By default, the unit is set to off. The goal here is to choose a setting that fits your needs.

For instance, the letter C will tell you to change the water panel after 600 hours, unlike the B option as it will only remind you to change the water panel after 300 hours.

You could leave it on the off position. But it’ll never tell you when to change the water panel.

So, once you’ve found the setting you feel most comfortable with, set the control to auto.

9. Wire The Control Up

On the bottom right side of the control panel, you should see the wiring terminal strip.

But before connecting the wires, here is what you should keep in mind:

  • The first one is R & C. This allows you to run 24 volts from the HVAC equipment.
  • The ODT is where you’d connect the outdoor temperature sensor
  • The W stands for the heat from the HVAC equipment.
  • The G refers to the fan from the thermostat.
  • The H terminal is meant to be used for the solenoid control output.
  • The GF must be used for the blower activation.

Once you’ve set up everything, put everything back on, and that’s about it. If you got lost somewhere in the process, check this video out for more information:

Frequently Asked Questions (FAQs)

If you’d like to expend your knowledge any further, here is some useful information about the humidifier:

Where is the best place to put humidifiers?

It depends on where you spend the most time.

For example, if you spend a lot of time in the dining room, and the humidity is pretty high, we suggest placing it there. Put on top of a table and cover the bottom side.

Is it OK to sleep next to a humidifier?

You can leave it running overnight. However, it would be best if you did not place it next to you.

Instead, put it further away, so that humidifier won’t bother you as you sleep.

Can you use tap water in a humidifier?

You should use distilled water. Tap water tends to make it misty, and it might cause mold.

You could also use cooled boiled water, but it’s probably cheaper to use distilled water instead.

Is it bad to use a humidifier?

Humidifiers are totally safe to use. However, keep this in mind: you should regularly maintain it. Otherwise, all the dirt that the filter has caught up in will make you sick.


The best advice to anybody who can’t figure out where to place humidifier is simply putting it where they spend a lot of time.

Think of it this way: by placing it where you regularly breathe, you’d make it easier for the humidifier to actually work.

Placing it somewhere where the humidifier is not needed is a waste of time and money.

You should also keep in mind that putting it too close to you might have some negative effects on your health.

Thus, place it a few feet away from you.
