The importance of having a humidifier in your home or office cannot be stressed enough. The dry air that’s found throughout many indoor environments can have a huge impact on your health after extended periods of exposure.

Having a humidifier inside your home not only makes the environment more habitable, but consuming more water will also make you feel full faster, as well as ensuring that your body remains hydrated.

Unfortunately, though, very few people are able to find quality humidifiers in the market today. Most humidifiers don't come with an awesome design, and don't last more than a couple of years, and often require constant maintenance.

But don't worry, I've prepared for you a detailed buying guide to the best humidifiers of 2021. You can also check out my list of the best humidifiers from 2018.

The last 6 months have been challenging for my family. Our daughter was born at 36 weeks and spent many weeks in the NICU. We struggled on what to do to keep her dry and comfortable at bedtime. The umbilical area was cracked and crusty, and she woke up every couple of hours to feed. The nurses recommended a humidifier and I purchased the iTvanila Cool Mist Humidifier.

The two things it does use, it has them. One big bonus is that it runs in a really low 45 dB, meaning I can run it at night, and unlike a lot of humidifiers, the family is hardly going to hear it.

The other is that it does do an entire house. It’s not a super large thing, but it is a nice large shape. That helps eliminate the need to buy a bunch of individual humidifiers for the different rooms.

Frequently Asked Questions (FAQ)

Which brand of humidifier is the best?

We’ve detailed our 13 favorite humidifier models above, but the truth of the matter is that each individual will have a unique opinion on the best humidifier brand. Everyone’s needs are different, and we’re all looking for something slightly different.

However, the humidifier industry leaders are Honeywell, Dyson, and Vicks. These brands are proven to be the most efficient and reliable when it comes to humidifiers. But, there are plenty of other brands that have really great humidifiers.

All three of the brand leaders have a number of different model options. They even produce models that are specifically catered to different needs. The Vicks V745A Humidifier, for example, is ideal for bedrooms. It not only acts as a humidifier but also actively purifies your air.

What is the best rated humidifier by Consumer Reports?

The Sunbeam S3300 MistAire Ultrasonic Humidifier is the best rated consumer-grade humidifier by Consumer Reports. It is also the bestselling humidifier on Amazon, with nearly 66% of reviewers giving it 5 stars.

It features an ultrasonic humidifier that can be run full-on or used to breathe out a fine mist. It can also be set to oscillate for a more dispersed humidity. The mist comes out in short and puffs, which makes it easy to direct. It can be set to several different levels of humidity and is one of the quietest models available at 68 decibels.

What is the best cool mist humidifier?

It is important to determine the difference between cool mist humidifiers and warm mist humidifiers. Cool mist humidifiers emit clean, cool, and moisture into the air to help keep you and your family comfortable. Since cool mist humidifiers do not warm or heat the water, they do not emit water vapor as warm mist humidifiers do. Warm mist humidifiers typically have the ability to heat and humidify larger areas than the cool mist humidifiers. This means that they may not be suitable for those living in small areas such as apartments or dorm rooms. Cool mist humidifiers are perfect for people living in smaller spaces.

What is the best placement for a humidifier?

One of the most important things to consider when choosing a humidifier is where you want to put it. Because there are both large and small humidifiers on the market, you may have a few options available to you.

Wall units tend to be slightly larger than standalone units but may offer you a larger tank and superior features. However these units are generally more expensive and you’ll need to make sure you have enough room for them.

Standalone units can work great because they can be taken with you, but be aware they tend to be a bit louder and don’t have the features wall units or larger units may have.

Where your humidifier will be placed will also determine the amount of noise it will emit. Most of the time, the larger the humidifier the louder it will be. The more humidifying power a unit has the more noise it will produce exponentially.

Conclusion

Humidifiers are a great way to take enjoy of the dry air during winter, or to make sure your home remains warm and healthy during the winter chill. Of course, you want to be sure that you use one of the very best humidifiers on the market. That’s why we review the in-depth features of many of the top-rated humidifiers, helping you get the best discount humidifiers for your home.
