quietest humidifier

A few months ago, I touched upon the benefits of owning a high-quality, quiet dehumidifier. And while some of my friends (and readers like yourself) struggle with humidity, I also know more than a few people who have issues with dry air. With that in mind, I decided to cover the other side of the proverbial coin of moisture. In other words, I began looking into humidifiers and vaporizers.

As a result of my research, I’ve compiled a list of the best quiet humidifiers of 2021. But that’s not all this article will cover. You will also get a handy guide on buying the right humidifier, as well as a list of useful tips on how to keep your unit clean and running. More importantly, you’ll find out just how important it is to own a humidifier and how it might benefit your life overall.

1. Crane USA Ultrasonic Humidifier

One of the key reasons for people to buy quiet humidifiers are, in fact, children. With a proper humidifier, you can get rid of bacteria from your newborn’s room and keep the little one safe. However, if that same unit is making too much noise, the child won’t be able to get the sleep it needs. So, as a parent, you will definitely enjoy Crane USA’s ultrasonic humidifier.

This stylish little unit has the shape of a transparent teardrop and it has a soothing, milky-white design. Of course, since it’s a humidifier designed for children’s rooms, it’s incredibly small. But don’t let that size fool you — this spectacular item can cover an area of up to 50 square feet.

In terms of noise, you will barely be able to hear the Crane USA. It’s ultrasonic, i.e., it runs at less than 30 decibels, well below any level of noise. When you turn it on, it’ll sound like a pleasant whisper, or like mild television static.

Crane USA will run for 24 hours if you leave it on the extra-low setting. However, any setting above that will deplete the water inside the tank sooner. Moreover, it has an automatic shut-off feature that activates once the water tank is completely empty.

One potential setback of Crane USA is the lack of filters. Sure, it will make your refilling job a lot easier, but regular maintenance will be a bit of a chore. If you live in a hard water area, you might need to purchase a demineralization filter, just to be on the safe side.


  • 24-hour runtime on the lowest setting
  • 360-degree mist nozzle for better coverage
  • 1-gallon water tank
  • Stylish and elegant design
  • Perfect for babies and young children


  • Difficult to clean
  • Doesn’t perform well in hard water areas without a filter

2. Pure Enrichment MistAire Humidifier

Another product that has a neat teardrop design and a 360-degree mist nozzle, the Pure Enrichment MistAire is a beautiful unit with a lot to offer. And when compared to Crane USA, it also shares the same basic setbacks. Mainly, if you were to use MistAire in hard water areas, it might underperform. In addition, the main water tank is difficult to clean, which might be a dealbreaker for some users.

However, the benefits far outweigh the flaws. MistAire is another whisper-quiet ultrasonic humidifier, running at 30 decibels. It’s perfect for bedrooms since it doesn’t take up a lot of space and isn’t noisy. Couple that with its 16-hour runtime on the lowest setting and you have the best recipe for a good night’s sleep, with enough moisture in the air.

Looking at the design, you might be tempted to buy MistAire just because of how beautiful it is. But the white-and-blue combination is there for more than just aesthetics. The light-blue, see-through tank lets you easily check how much water you have left. And thanks to its 360-degree nozzle, it can reach a wide area, making it suitable for large and small rooms alike.

I feel that it’s instructive to note just how popular Pure Enrichment MistAire really is. On Amazon alone, there were a staggering 10,000 units sold, making it one of the most sought-after humidifiers. That fact alone earns MistAire a spot on this list.


  • 360-degree mist nozzle for better coverage
  • Stylish and elegant design
  • Perfect for both large and small rooms
  • 16-hour runtime on the lowest setting
  • Automatic shut-off function


  • Difficult to clean
  • Doesn’t perform well in hard water areas without a filter

3. Vicks Warm Mist Humidifier

Vicks is the first warm mist humidifier on this list, and it’s here for a good reason. Just like MistAire, this product has had thousands of units sold over the years, with people praising it as one of the best warm mist humidifiers on the market.

Naturally, all of the praises Vicks is getting are warranted. After all, Vicks is a household name that has produced high-quality items for decades. Everyone knows the health benefits of their most famed product, the VapoRub. So, it was only a matter of time before the brand included humidifiers and vaporizers in its product line, including the one you’re currently reading about.

As a warm mist humidifier, Vicks removes over 95% of all bacteria from the air. Couple that with the automatic shut-off feature and you get a splendid unit that performs incredibly well and helps you stay healthy. Moreover, Vicks doesn’t use filters, so you won’t have to go through the hassle of replacing any after the water runs out.

Lots of humidifiers, both warm and cold mist ones, don’t have any humidity regulation settings. But Vicks most definitely has it; thanks to its two output settings, you can regulate the level of moisture at any given time.

In terms of runtime, it’s a bit behind the previous options I mentioned, at 12 hours on the lowest setting. But that’s more than enough time if you want to keep the unit on while you’re asleep.  


  • 1-gallon water tank
  • 12-hour runtime on the lowest setting
  • Stylish and economic design
  • Perfect for cough and congestion relief
  • It can use aromatic pads for added comfort
  • Medicine cup for inhalants


  • Bacteria removal not as effective as other warm mist options
  • Difficult to clean

4. Honeywell HCM350W Humidifier

The HCM350W has been on the top 10 lists since early 2020, and to date has remained one of the best-rated units out there. Thanks to its simple and effective design and noise-free performance, it’s possibly the most high-quality product that Honeywell has to offer.

With its 1-gallon tank, the HCM350W will have more than enough water to provide your room with cold mist. It will maintain the humidity level between 40 and 60, i.e. the perfect level for improving your overall health. Your skin, breathing, and sleeping pattern will improve and there will be next to no static electricity in the air.

One unique feature of Honeywell’s HCM350W is its native UV technology. When it’s humidifying, this unit will get rid of 99% of harmful bacteria from the air. It’s a perfect humidifier for the winter months, since it will keep your flu and colds at bay.

When using the lowest setting, you can humidify the room with HCM350W for 24 consecutive hours. Not only is that perfect for your sleeping schedule, but it’ll also keep your home hydrated if you’re away for a while.

Of course, the HCM350W has its own flaws. For instance, it uses filters that you will need to replace often. However, the filters are quite expensive, so you’ll be spending a lot of money to keep this device running smoothly. In addition, you will have to replace the wick regularly, as well as frequently take the fan out and clean it.


  • 1-gallon water tank
  • 24-hour runtime on the lowest setting
  • 99% bacterial removal
  • Water tank is easy to clean
  • Stylish and elegant design
  • Helps prevent health issues


  • Replacement filters are too expensive
  • The fan is difficult to clean

5. VicTsing Cool Mist Humidifier

VicTsing is possibly the best budget-friendly cool mist humidifier. If you want a portable, whisper-quiet option that won’t cost you a lot of money, then look no further than this wonderful, white-blue item.

Running at 32 decibels, the VicTsing is only barely louder than some of the more expensive devices out there. However, it’s still silent enough to the point where you won’t even notice it’s on.

The water tank of VicTsing has a half-gallon capacity, making it perform somewhat less efficiently than the other options on this list. Despite the tank size, however, this item has a runtime of 10 hours on the lowest setting, which is perfect for running it at night while you’re asleep. And in case that half a gallon water is used up, the automatic shut-off feature will turn the humidifier off. Moreover, the LED lights will warn you in advance if the water runs out.

Unlike other commercial humidifiers, the VicTsing has a simple set of controls. All you have to do is turn one know to the desired setting and you’re all set. However, I should stress that you must be careful when setting up your VicTsing. It has the tendency to leak condensed water around its base, so put a tray or a towel beneath the unit, just to be safe.


  • One of the most affordable humidifiers on the market
  • 10-hour runtime on the lowest setting
  • LED lights and automatic shut-off feature
  • Portable and easy to set up
  • A single knob that controls everything about the unit


  • Potential water leakage if you use it on the highest level
  • Not as durable as the pricier products on this list

6. TaoTronics TT-AH001

TaoTronics has taken the humidifier market by storm. In fact, if you merely mention that you need to buy a humidifier, one of the first brands that people will recommend to you is TaoTronics. And one of the first products that you’ll get recommended will definitely be TT-AH001.

On the surface, the TT-AH001 looks quite innovative. There are a few basic humidifier designs that most companies stick to, so there isn’t a lot of room for innovation. But TaoTronics managed to find a way, and TT-AH001 has a futuristic, high-tech appearance that tech junkies will simply love.

Of course, it’s not all about the looks. The TT-AH001 performs extremely well, with a 1.6-gallon tank and a 24-hour runtime. And while it does run at 38 decibels (more than other products on this list), it’s still one of the quietest humidifiers on the market today. More importantly, it can cover a vast area — up to 322 square feet, to be exact.

The TT-AH001 also excels when it comes to safety. The automatic shut-off sequence allows you to save power when the water in the tank runs out. Moreover, the patented microporous cartridge will keep the microorganisms and bad odor away, giving you fresh, humid air. All of these properties make this unit perfect for your baby’s room.

Finally, unlike a lot of other humidifier options out there, the TT-AH001 also has a humidistat. With the push of a button, you can choose between several different mist settings and humidity levels.


  • 24-hour runtime on the lowest setting
  • Microporous cartridge for cleaner water and air
  • 1.6-gallon water tank
  • Wide coverage area
  • Humidistat with several different humidity and mist options to choose from


  • No handle for carrying it from room to room
  • The tank isn’t attached to the base, which might cause spilling

7. TaoTronics Cool Mist Humidifier

Yes, TaoTronics as a brand is so popular that it’s no wonder two of their products ended up on this list. And based on user feedback, this particular humidifier does, indeed, excel across the board.

The TaoTronics cool mist humidifier stands out from the crowd thanks to its own unique design. And while the TT-AH001 has that futuristic, SF feel about it, this item looks like a modern work of art. The sleek black exterior with shades of blue and white was a bold choice by TaoTronics. No matter where you put this unit, it will fit right in and even bring a dash of class to the room.

Performance-wise, this TaoTronics product has a lot to offer. For instance, it can run for a whopping 60 hours without refilling. That’s almost three times more than some of the bestsellers out there, and almost six times more than some of the options listed above!

And the large numbers don’t end there, either! Thanks to its 360-degree swivel nozzle, the cold mist humidifier can cover a huge area of 430 square feet. That makes it ideal for large bedrooms, but it’s just as effective in snug, compact spaces.

Of course, with that type of water tank capacity and runtime, you’d think that a beast like this unit has to be loud. But then you’re in for a shock; not only is this TaoTronics product quiet, it’s in fact quieter than every other product I’ve listed. It runs at an incredible 26 decibels! In short, it seems as if you can’t get any better than TaoTronics.


  • 60-hour runtime on the lowest setting
  • 360-degree swivel nozzle for ultimate coverage
  • Covers a huge area
  • Quieter than any other option on the market today
  • Automatic shut-off function
  • Stylish and elegant design


  • No ability to adjust the mist type or temperature
  • Nightlight cannot be switched off

Quiet Humidifier Buyer’s Guide

Humidifier Type

Broadly speaking, there are two major types of humidifiers. Based on the type of mist they create, they are classified as either cold mist or warm mist humidifiers. However, you might also come across a third type. Known as a dual humidifier, this product can produce both hot and cold mist, depending on your needs.

Cold Mist Products

As the name suggests, these humidifiers produce cold mist. In terms of availability, they are the most common type on the market because of how safe and reliable they are.

Cold mist humidifiers themselves have two subcategories. The first of the two includes the so-called evaporative models. This type of humidifier uses a wick filter; a fan will blow into the wet wick, causing the air to cool in the process. And while this process is great if you want to avoid any mold and mildew growth or water condensation, the wicks are expensive and they need to be replaced frequently.

The second subcategory of cold mist products includes the ultrasonic models. They use a small vibrating diaphragm called a nebulizer to produce a fine mist. And because they have no fans, these models are some of the quietest on the market. However, lots of water tends to condense around an ultrasonic humidifier, so the surface below can get soaked.

Warm Mist Products

Warm mist products, also known as steam vaporizers, are not as common as cold mist humidifiers. However, they are usually not very pricey, so people tend to buy them quite often.

There are a few setbacks to warm mist humidifiers. A typical unit uses a heating element to boil the water inside and release warm mist. With that in mind, you have to be careful with the humidifier, since the water can cause severe burns. In addition, the warm mist isn’t something you want in your home if you have a cold, since it can cause your nasal passages to swell and endanger your breathing.

Of course, the benefits outweigh the drawbacks. A typical warm mist humidifier is perfect if you’re in the middle of winter because the mist will maintain warmth inside the house. In addition, you can use a warm mist unit together with a medical inhalant for cough relief. 


Each unit has a water tank, and when picking the right humidifier, you need to find out what the tank’s capacity is. That way, you’ll know when and how to refill it and, more importantly, how big of an area it can cover.

Depending on how large your bedroom is and how often you spend your time at home, you’ll probably need a humidifier that can produce mist for at least 24 hours. If possible, get a product that goes well beyond that capacity.

Coverage Area

Coverage area is actually intimately linked to the water tank capacity; usually, the smaller the capacity is, the smaller coverage the humidifier will have.

Now, if you have a large bedroom, you don’t want to buy a humidifier that’s too small. It will be a waste of money and you won’t get the desired humidity. But the same goes for oversized units; unless you plan on covering more than one room with the same product, don’t waste money on something huge.


Some users will only have the humidifier on for a couple of hours. However, if you have a snoring problem or live in an incredibly dry area, you will need to keep the humidifier on for a lot longer than that. So, when buying a unit for yourself, make sure that it has the runtime that suits your needs. The rule of thumb is simple: the bigger the water tank, the longer the runtime.

Noise Level

It should go without saying that, in order to get the best quiet humidifier, you’ll need to get one that produces a specific level of noise. But how can you know which units are quieter than others?

Before buying a particular brand of a humidifier, check their sound pressure level. If it’s anywhere between 32 and 38 decibels, you’re good to go. Furthermore, check the type of your unit as well; ultrasonic humidifiers usually produce the least amount of noise.   

Warranty and Price

Just like any other electrical appliance, a humidifier should be made to last. With that in mind, when shopping for your vaporizer of choice, always check the warranty. A typical humidifier can usually run for a couple of years, with the high-end models lasting for over a decade.

In terms of pricing, it comes down to what type of product you need and how often you plan on using it. Personally, I’d suggest avoiding ultra-cheap models, since they could be underperformers. On the other hand, you don’t have to pay thousands of dollars just for a humidifier. Instead, do a bit of market research and track down the best-rated models, like the ones on the list above. Then pick a model according to your budget and specific needs.

Bonus Features

Bonus features are not vital to a humidifier’s performance. However, they can actually prove to be invaluable to you. For example, if your humidifier has an automatic shut-off function, you don’t have to physically turn it off after waking up in the morning. Once it’s done humidifying the room, it’ll shut off immediately. Other features involve smart LED shut-off indicators, extra controls for intensity and mist type, and the ability to add scented liquids and essential oils to the water tank.

Frequently Asked Questions About Humidifiers

Why Should I Buy a Humidifier?

There are more than a few benefits to owning a humidifier. In fact, using one on a daily basis can actually improve your overall health in several important ways.

An average humidifier gets rid of harmful particles in the air while making it ‘wetter.’ Moist air will add some humidity to your airways and sinuses, which will reduce the risk of asthma and various allergies. In addition, you will be less likely to catch the flu and your coughs will contain more moisture; the more mois the cough, the more phlegm you’ll release during a cough.

Most of us tend to have some skin or hair issues, and dry air is, more often than not, responsible for them. The same goes for cracked or chapped lips. So, if you want to see your skin glisten again or your hair reclaim its full volume, a humidifier is definitely the way to go.

Now, snoring might not be as serious as influenza or allergies, but it is a problem lots of modern households face. In order to get rid of that pesky snoring habit, you’ll need more humidity in the air as soon as possible.

Finally, a humidifier is just as beneficial to your home, your pets, and your plants as it is to you. Like us humans, animals require some moisture in the air to help them with their own allergies or illnesses. Plants, in particular, will benefit from being in an environment with lots of humidity, as it boosts their growth and development. As for our homes, both wooden floors and brick-and-mortar walls can crack over time due to dry air, so some humidity is necessary.

How Should I Maintain My Humidifier?

If you own a humidifier, you have to remember to clean it regularly. A dirty unit can and will produce a lot of noise. In addition, it can be a breeding ground for bacteria, mold, and other invasive living beings. 

With that in mind, here are some basic tips on how you can clean and maintain your own unit:

  • Read the instructions well and stick to them
  • Wash and dry the unit after each and every use
  • Find the proper cleaning tools and chemicals
  • Always use fresh distilled water
  • Replace the filter
  • Clean it before and after storing it
  • Make sure that the area around the humidifier is dry
  • Unplug the product when you’re done using it

How Often Should I Refill the Humidifier?

On average, a portable quiet humidifier can operate for 24 hours before you need to refill it. Of course, there are other brands, both portable and otherwise, that operate for even longer periods than that. So, generally speaking, you will need to refill it every 24 hours or so, at least.

Where Do I Place the Humidifier?

When it comes to your bedroom, the best place to put a humidifier should be at least 3 feet away from the bed. However, there are other, general guidelines you ought to follow. For instance, make sure that the unit is at least 2 feet above the floor and that it’s on a level surface that isn’t wood or metal. If you HAVE to place it on a metal or wooden surface, simply put a plastic tray between the surface and the unit itself.

How Can I Make It Even Quieter?

It depends on what type of humidifier you’re using. In general, try the following steps:

  • Place the fan away from walls or anything else that might obstruct the airflow
  • Put the humidifier on a folded rag or towel so that it doesn’t vibrate as much
  • Take the top off the impeller tip
  • Replace the filter

Should I Use Distilled Water?

Distilled water is the recommended option. In fact, you can even buy distilled water specifically for humidifiers. However, there are brands out there that can use tap water perfectly fine.

Will Any Water Leak on My Floor?

The short answer is yes. Because of vapor emission, water will condense on the humidifier and drip to the floor. That’s why using a towel or a rag is highly important.

Can I Add an Oil or a Fragrance to the Water?

Some brands of humidifiers support this option, others do not. Before you try to do it, contact an expert or research your favorite brand of humidifiers. Adding anything other than water to the unit might damage the circuitry.

Final Thoughts

Proper air humidity is incredibly important to our health and wellbeing. I’ve personally met a lot of people who think that a humidifier is a “luxury item” and that it serves no real purpose. But that’s simply not true; a high-quality, quiet humidifier can help you keep your health in check. And if you pick one of the options from the list above, you’re also guaranteed to get your much-needed beauty sleep every single night.
