Top 7 Best Humidifiers
#1 Homech Quiet Ultrasonic Humidifier
We’re sorry, this product is temporarily out of stock
Award: TOP PICK
WHY WE LIKE IT: Large water tank that offers 60 hours of continuous use with an auto-shutdown functionality, for safety, and a quick clean design that helps to prevent mold from growing.
- 60 hours of continuous use
- Auto shutoff when tank is dry
- Quick clean design helps to prevent mold from growing

The Homech Quiet Ultrasonic Humidifier puts high-quality moisture in the air, with a four-liter water tank that offers 60 hours of continuous use without having to pause for a refill and an innovative design that automatically shuts down when the tank is empty, for electrical safety. We also loved the quick clean design, which reduces the chances of mold growth, and the quiet operation of 26dB. Although, if you’d like a great air purifier/humidifier, we have a round-up of those, too.
This humidifier does not feature a night light, which could be an issue for children who enjoy that feature, though could be a boon to those who like to sleep in absolute darkness. Additionally, no indicator imparts information as to how much water is left in the tank. If you want a purifier specifically for asthma issues, take a look at the best air purifier for asthma.
#2 TaoTronics Cool Mist Humidifier
We’re sorry, this product is temporarily out of stock
Award: HONORABLE MENTION
WHY WE LIKE IT: Features an extremely quiet operation, 26dB, with an innovative slim design that eliminates the sounds of water dripping, in addition to a built-in handle for carrying and a notification system that alerts users when water is low.
- Very quiet operation
- Notifies when water is low and shuts down automatically when dry
- Convenient carry handle
- 50 hours of continuous use, slightly lower than top pick
- Can get mineral buildup if not cleaned often
- Bottom fill design not for everyone
The TaoTronics Cool Mist Humidifier operates quietly, with a noise level of just 26dB, and an innovative slim design that drastically reduces the sound of water dripping, an issue that can plague some models. We also loved the built-in handle, for convenient carrying, and the notification system that lets users know when water is low, in addition to an auto-shutdown functionality when all water has dissipated.
Though this is a four-liter design in line with our top pick, we found that it maxed out at 50 hours of continuous use, whereas our top pick worked for 60 hours before needing a refill. Also, this product is easy to clean but can suffer from mineral buildup if not cleaned at least once a week. So while it might not be the best for a household, it would probably be a great air purifier for the office.

#3 Levoit Ultrasonic Cool Mist Humidifier
Award: MOST PORTABLE
WHY WE LIKE IT: Compact and light form factor, with a removable power cord for easy transport, with several features that make it excel for babies, including adjustable night light, 3 mist levels, and components that are BPA and toxin-free.
- Best for babies

- Does not prevent against mold and bacteria
The Levoit Ultrasonic Cool Mist Humidifier is the best humidifier for a baby that we tried, thanks to a quiet operation, around 30dB, an adjustable night light, three mist levels, and components that are free from BPA and related toxins. The quick clean design is fantastic, as is the compact and portable form factor, complete with a removable power cord for easy transport, making this an excellent portable humidifier. For another option, compare the Molekule Air Mini vs the Air Mini Plus.
The supreme portability does come at a cost, however, as this is one of the smaller humidifiers on this list, with a 2.4-liter capacity and the ability to run continuously for around 24 hours on the lowest setting. Additionally, this product has no functionality built-in to prevent mold and bacteria, so we’d recommend cleaning it once a week with bleach.

While it doesn’t have a nightlight like this device, the Dyson Pure Humidify+Cool PH01, has a nice nighttime feature.
The six-liter capacity does make this unit somewhat difficult to clean, and the manufacturer recommends weekly maintenance. Also, this humidifier is over five pounds, which can be frustrating if you find yourself wanting to move the product from room to room.

This is a small capacity humidifier, however, with a maximum fill level of just 1.5 liters and a continuous run time of around 16 hours on its lowest setting. Also, we found this item to be somewhat difficult to clean, with several parts, each containing nooks and crannies.
#7 Pohl Schmitt Viral Support Humidifier
Award: BEST ON A BUDGET
WHY WE LIKE IT: Budget-friendly product with plenty of high-end features, including a built-in night light, and a sensor that automatically shuts the unit down when all water has been dissipated. This could be considered one of the top air purifiers under $100.

How We Decided
To help narrow down the above list, we first ensured that each of our picks featured enough capacity to easily humidify a standard-sized bedroom, with several picks boasting large enough water tanks to humidify an entire home. We liked products with nozzles that swiveled 360 degrees, for disbursement, and those with several speed settings.
We liked models that were relatively easy to clean and those that contained a suite of sensors that automatically powered down when the tank became low or completely dry, which helps to protect the interior electronics. A quiet operation was also of paramount concern, as all of our chosen picks operate at 30dB or lower. You can also get a portable purifier that can be the best car air purifier.
We also loved items with additional features, such as calming night lights, built-in filtration systems, and easy-to-use touch-enabled surfaces.
Best Humidifier Buyer’s Guide
The Most Important Features to Consider
- Tank Capacity and Coverage
If you are looking to humidify a small bedroom, such as a baby’s room, any sized model will do the job. If you are looking to cover a large living area, such as a dining room, or an entire home, you are going to want to pick something with a capacity of at least four liters, though six liters may be preferred. Large tanks can also allow the unit to operate continuously for lengthy periods, as long as 60 hours in some cases. - Automatic Shutdown and Notifications
You will likely want to choose a product that comes equipped with sensors that automatically shut the humidifier down when the water has been depleted, thus ensuring the interior electronics will remain undamaged. Some items go a step further, offering up notifications that let you know when water is running low, so you can refill before it gets depleted, while others display other useful metrics, including humidity level. - Filters
You may want to choose an item with a reusable and replaceable filter, which can help purify the water before it is dissipating into mist. These filters can increase the humidifier’s effectiveness when it comes to the reduction of symptoms from sinus issues, allergies, and other ailments. If a unit does not include a filter, it will usually require a thorough cleaning around once a week, to remove excess mineral build-up. - Additional Features
Many humidifiers come with all manner of additional features, including adjustable night lights and timers, so you can plan ahead of time as to when your room will be humidified. Other features include filters that make sure the dispersed moisture is of the highest quality and a convenient carry handle, making it easy to move the unit from room to room as needed.
