7 Best Humidifiers For The Bedroom


Looking for the best humidifier for the bedroom? We’ve got you covered.

Do you suffer from dry skin, allergies, chapped lips, nosebleeds, sinus headaches, or eye irritations come wintertime?

These are just a few of the many common health issues that can be caused by dry air in the atmosphere.

If this sounds like you, fortunately there is something that can be can be done to alleviate these complaints — installing a humidifier in your home.

We’ve got the full-run down on the best humidifiers on the market, as well as everything you need to know before you buy.

Let’s get straight into it…

What is a Humidifier?

Humidifiers come in a wide range of forms, but they are all designed to perform one single important function —  put moisture back into the air .

Evaporative humidifiers achieve this by using an internal fan to pull air into the unit and pass it across a water-saturated wick filter to absorb moisture.

Once the air has been humidified, it is pushed out again by the fan to circulate around the environment as a fine mist.

Ultrasonic humidifiers achieve the same effect by using an ultrasonic vibrating diaphragm to create super fine water droplets which are then forced into the atmosphere.

Humidifiers are available in both cool mist and warm mist versions.

Cool Mist Humidifiers
Cool mist humidifiers transform water into a mist with a slightly lower temperature, making them a good choice summer as well as winter use.
Warm Mist Humidifiers
Warm mist humidifiers heat water to boiling point in order to vaporize it to enable the heat energy generated to move the warm mist about in the air.

Some humidifiers are capable of generating both cool and warm mist.

As an added bonus, installing a humidifier benefits not just you but your home too, preventing damage to walls and furniture caused by long periods of exposure to dry air.

How will a Humidifier Help Me Sleep?

Another good reason for investing in a humidifier is that is can improve your quality of sleep.

Not only does a moist environment feel warmer and more comfortable, but it is also better if you or your partner snores or suffers from sleep apnea.

How can a Humidifier Help Snoring?

If your snoring is caused by allergies or upper respiratory illness, a humidifier can usually help by enlarging the air passageways when you sleep and ensuring that air enters your lungs easily, thus eliminating snoring.

How can a Humidifier Help Sleep Apnea?

Similar to snoring, sleep apnea is caused by narrowing of the air passageways during sleep which prevents enough air getting to the lungs, and in severe cases stops airflow completely.

Keeping the air in your home clean and moist by using a humidifier also helps keep your nasal passageways clean and moist too, reducing sleep apnea symptoms or even preventing it entirely.

Features of the Best Humidifiers for the Bedroom


When you’re trying to get to sleep, the last thing you need is a noisy humidifier whirring away in the background.

One of the main features of the best humidifiers is that they run quietly so as not to disturb your sleep.


A humidifier should be straightforward and easy to use, as well as simple to set up and easy to clean.


It may seem obvious, but a top notch humidifier will have a decent moisture output, and preferably adjustable humidity settings.


Humidifiers generally undergo heavy use, and the best humidifiers are deigned to be durable and energy efficient in order to cut down on running costs.

What Size Humidifier do I Need?

There are a whole host of humidifiers in a wide range of shapes and sizes — from table top machines to whole house humidifiers — so the size of humidifier you need is dependent on how you want to use it.

If you want to disperse moisture throughout your entire home, a house humidifier can achieve that by connecting to your HVAC system and water supply.

If you just want to humidify a single room, a small tabletop humidifier will do the job.

In addition, choosing a humidifier with a larger water capacity means that you won’t have to refill the tank as often as a smaller one, although larger units can be heavier and more awkward to fill up.

In general you should choose a humidifier the right size and capacity in square feet for the space you want it to humidify.

Where Should a Humidifier Be Placed?

Where you position your humidifier is actually surprisingly important. Firstly it should be placed  in the room where it is going to be used the most  — unless it is has an easily portable design.

When using a warm mist humidifier in a bedroom it shouldn’t be placed too next to the bed or close to pillows and sheets as they may get damp.

Wherever possible,  warm mist humidifiers should be elevated  and placed on an item of furniture at least 2 feet off the ground to prevent any mold or mildew forming beneath or behind them.

Cool mist humidifiers, on the other hand, can be placed near the bed — preferably on a bedside table of chest of drawers — but it’s critical to leave a space of at least six inches between the device and wall to allow proper air circulation.
