Things to Consider

Whether you’re torn between two humidifiers or just cannot decide from the entire market of products, let our buying guide help you choose the best pick not only for the health of your family but also the size of your home.

Why buy a humidifier and what problems can it solve?

There are so many benefits to a humidifier and clean air in your home. We might be so bold to say that. Actually, it may even solve problems you didn’t even know you had — or help prevent them from arising.

Here are some health benefits of a humidifier:

  • Can prevent influenza: A humidifier in the home can reduce your risk of catching the flu since it gets rid of harmful particles in the air.
  • Reduce snoring while you sleep: The more moisture in the air, the less snoring from your sleeping partner (or you).
  • Reduce asthma and allergy symptoms: When your sinuses and airways are dry, you’re more susceptible to allergic reactions or asthma-related issues. Moistening these airways up can help you a ton!
  • Relieve your cough: A “wetter” cough can help release all that trapped phlegm in the esophagus and the throat.
  • Not only does it keep your cough moist, but it also helps the skin and hair. Not to mention smoothing cracked lips!
  • Can help your house and plants. You should invest in a humidifier if you have wooden floors, walls or furniture. Not to mention your houseplants that will definitely thank you!

Features to consider while choosing a quiet humidifier

Before you go out and buy your new humidifier, make sure you pay attention to the details. Some features that may seem not that important at first can play the crucial role later, after the purchase,

when you realize that the coverage area doesn’t suit your room, or the tank capacity is way too small. Keep reading to be armed before your next shopping trip.

Noise level

Choosing the quietest room humidifier, like the Bionaire Ultrasonic Warm and Cool Mist Humidifier can make all the difference—especially if you are planning to keep it running while you are sleeping.

32-38 decibels is a great range of noise to have when you’re choosing a quiet humidifier for a bedroom or a nursery.

Mist type

Cool mist humidifiers, as the name states, are producing cold mist, creating a pleasantly cool and humid home environment. Warm mist humidifiers heat the water inside, helping to fight the growth of bacteria.

These models are less common and are not advised for homes with kids because of the heating element inside that can be potentially dangerous if the running unit is accidentally upended. Most of the quietest humidifiers, like the VicTsing Humidifier, is only available with the cool mist function.

However, there are various models that allow for adjustments between warm and cool mist, like the Bionaire Ultrasonic Warm and Cool Mist Humidifier.

Water tank capacity

The water tank capacity is an essential feature — you don’t want to have to keep on changing the water on an everyday basis! Take a look at the water tank capacity, whether it’s in gallons or liters, to know which humidifier is right for you. On our list, the AIRCARE 831000 Space-Saver has the biggest capacity, at six gallons.


The runtime is also important to note. Especially if you plan on sleeping with it (to help with snoring), knowing how long it can run for without a need to be refilled. Usually the bigger the water tank, the longer runtime you can expect.

Coverage area

If you live in a large area, knowing the coverage capacity of the humidifier can make all the difference! You wouldn’t want to invest in a humidifier just to find out it doesn’t really reach all corners of your home.

Likewise, don’t buy a humidifier that is designed for whole house usage in case you just intend to use it for one room: a waste of money and space!


The warranty period is also a great feature to look at. To be assured about making the investment and knowing that it will last for many years you and give you the most for your money is a great feeling.

Extra features

There are also a few additional features that can add value to your humidifier. For example, the auto shut-off can come in handy when you’re asleep. Once the humidifier is empty, the LED light indicators and automatic shut-off keep the unit from overheating.

Extra controls to be able to choose the type of mist or how intense you want your humidifier to be can also come in handy.

Tips to keep your humidifier in perfect condition:

  • Although it might seem impossible to keep anything in a perfect condition, these quick tips can definitely help keep your humidifier running smoothly!
  • Change the humidifier water and filters regularly: check the manufacturer recommendations.
  • Use distilled or de-mineralized water for the best results.
  • Always rinse out the tank when you’re cleaning it.
  • Clean or change the filters regularly if your humidifier comes with one.
  • Unplug the unit when not in use.


Lastly, we’re going to go ahead and answer some of the most frequently asked questions we’ve seen roaming around out there about humidifiers:

How do I know when the air is humidified enough to shut the unit off?

The AIRCARE 831000 Space-Saver, for example, shuts itself off automatically after the air is humidified “enough” or the water runs out. This is a great feature to look for in a humidifier as it really does give you some peace of mind.

To get scientific, you should be looking for a healthy humidity level that measures between 30% and 50%. To help measure the humidity, a hydrometer can help.

Can these devices be left operating overnight?

Yes, absolutely! If the runtime equates to an overnight timespan, it can definitely be run overnight. If you’re going to be choosing to run it only overnight, a cool mist option is your safest bet.

My humidifier model comes with a filter. Where do I get the replacement ones and how often should they be changed?

Typically you should be replacing your humidifier’s filter every three months. If you’re using it every day, replace it every two months. The replacement filters can be found on Amazon as well as the manufacturer website.
