Best overall

The Pure Enrichment MistAire is an ultrasonic air humidifier that dampens dry air for 25 hours. It has a 1.5l capacity for more coverage and activates its auto shut-off feature at low water levels.

  • It may be a bit noisy


This humidifier is an excellent product from Pure Enrichment. It efficiently reduces air dryness and balances the humidity level in your rooms to prevent sinus issues. To aid this, the product’s design features a mist nozzle that rotates 360 degrees.

This air humidifier employs ultrasonic cool mist technology to quickly dampen dry air wherever it is placed. The product is safe because its body is made from BPA-free ABS plastic.

Its 1.5-liter tank capacity holds enough water for better coverage of your rooms. However, depending on the level of air dryness in your room, you may find it more suitable for small to medium rooms. Further, the tank has an inlet that is wide enough to fill with kitchen or bathroom faucets easily.

It’s a plug-in humidifier, which ensures around-the-clock dry air moisturizing. It typically runs for up to 25 hours. This product also has adjustable speed settings, allowing you to switch from low to high or vice versa, keeping you in control of your room’s humidity level.

We like that it has an auto shut-off feature that turns the device off when the water level is low, and it has a little bulb that glows in the dark. The product is easily disassembled for refills and comes with a cleaning brush for easy maintenance.

Despite this device’s long list of merits, some clients have complained about leakage problems from the tank. Some also found the noisy operation of the motor and gurgling water sounds a demerit. The good news is a 5-year money-back guarantee covers the product to compensate dissatisfied clients.

Altogether, the Pure Enrichment MistAire is the perfect humidifier for small to medium rooms. You are sure to get value for your money with this device.

AquaOasis™ Cool Mist Humidifier (2.2L Water Tank) Quiet Ultrasonic Humidifiers for Bedroom & Large room - Adjustable -360 Rotation Nozzle, Auto-Shut Off, Humidifiers for Babies Nursery & Whole House

Runner up

With a 2.2l capacity, this AquaOasis ‎HD-1 promises balanced humidity in your rooms for up to 24 hours. It also offers exciting features like a mist and nozzle adjuster for personalized performances.


  • Ultrasonic humidifier
  • 2.2 liters water tank
  • Up to 24 hours of run time
  • Mist and nozzle adjuster
  • Auto shut-off


  • High mist setting only lasts 6-8 hours
  • Leakage problems


With a 2.2-liter water tank, the AquaOasis ‎HD-1 makes a good choice for medium to large rooms. It is an ultrasonic air humidifier that utilizes cool mist technology to moisturize dry air in whatever space it is placed in, so you can bank on its effectiveness.

Like most designs, it is filled through an opening below the tank and has a nozzle that distributes cool mist at the top. The nozzle can rotate 360 degrees to set it to your preferred angles via a knob on the product’s base. In addition, the mist level can also be adjusted, further ensuring even distribution of cool mist around the room.

While the manufacturers state the tank doesn’t need a filter, we would recommend you use distilled water regardless. The device’s auto shut-off feature is one you’d like. Whenever the tank is about to run out of water, the feature is activated, and your device shuts down temporarily until the next refill.

If you’re worried about maintenance, there’s a cleaning brush included in the product package for fast and easy cleaning. The makers of this product guarantee a run time of up to 24 hours on a full tank, but some users have claimed it barely lasts 6-8 hours on the lowest and highest mist levels.

Another demerit is that there were several reports of leakage problems from previous users.

Apart from the leakage problems, we think this humidifier is a good option for large rooms and does a great job eliminating dry air.

Considering its large size, we like that there’s a cleaning brush included in the package to reach the nooks and crannies of the product.

Our favorite feature of this device is its quiet mode of operation, and many users have attested to that fact. However, some users have complained about the inaccurate hygrometer readings, saying it sometimes reads less than the room’s humidity level.

In terms of efficiency, it works in ultrasonic mode, dampening the air in your rooms. At first glance, its 250ml tank capacity appears on the low side, but remember, it is a portable device best suited for small spaces. For instance, you can place it in your car’s cup holder or work table to humidify those areas.

This device has a run time of up to 8 hours, which is pretty okay considering its tank size. It is corded and uses a USB cable for fast recharges.

You will find a button on its right side for switching mist levels from continuous to intermittent mode. We like that these two modes allow you to regulate the humidity distributed to the room based on the level of air dryness.

As expected, its tank is easily refilled by turning the black upper part clockwise to unfasten it. And the product is designed to cut off operations when it detects low water levels, all courtesy of the auto shut-off feature.

Citing some user reports, the product leaves covered in white or gray dust wherever it is placed. Likewise, some have complained about the nozzle’s lack of a 360-degree feature, which has them manually placing it in their preferred directions.

Overall, this is a good low-cost product that offers you more than its price, and we think it would be an excellent addition to your nightstand.

Humidifier buying guide

Humidifiers play a vital role in dampening dry air in your rooms during any season. To make certain you make the best decision while shopping for one, we have provided features to look for, how it works, maintenance, and more in this buying guide.

What is a humidifier?

A humidifier is a device that eliminates or reduces air dryness by introducing moisture into the air. This device is handy for preventing skin or nasal dryness and irritation during any season, especially winter. It also helps to relieve symptoms associated with cold or flu, such as cough, runny nose, or blocked nose.

Humidifiers’ work differ based on the type. An ultrasonic air humidifier, for instance, works by using high-frequency vibrations to convert water in its tank (usually distilled water) into cool mist, which is then released into a room through its nozzle. Some humidifier nozzles have a 360-degree feature, allowing even distribution around the room.

What are humidifiers used for?

You can use humidifiers to relieve the following:

  • Blocked or bloody nose
  • Dry cough
  • Dry or sore throat
  • Dry throat and skin
  • Cracked lips

Types of humidifiers

There are five main types of humidifiers, which all provide the same results but in different ways. They are detailed below.

Steam vaporizers

Steam vaporizers are powered by electricity and operate by heating and cooling water before blowing it into the air. Due to their portable sizes, they can be bought in neighborhood stores and are very affordable. However, they are only suitable for adult rooms because the boiling effect makes them hot and may cause burns if touched.

Impeller humidifiers

Impeller humidifiers work by using high-speed rotating disks to dampen dry air. Unlike steam vaporizers, they are affordable and can be used in children’s rooms as they do not cause burns.

Central humidifiers

This humidifier type is designed to humidify a whole building. This is achieved by incorporating the humidifier into a building’s heating or air conditioning system. Central humidifiers are very expensive to buy, install, and maintain.

Ultrasonic humidifiers

Ultrasonic humidifiers use high-frequency vibration to produce cool or warm mist. They are primarily portable and suitable for single rooms. The humidifier’s tank size determines the space you can place it in; a small tank size would go in a small room and vice versa.


Evaporators use fans to distribute moisture via a wet filter, belt, or wick. However, they may sometimes over-moisturize the air, increasing the possibility of mold growth, which may be an issue for asthmatic people. They are relatively cheaper than central humidifiers.

What should you consider before buying a humidifier?

The essential features and factors you should consider before purchasing an air humidifier are described below.
small humidifier

Tank capacity

The ideal humidifier tank capacity depends on your needs, room size, or preference. The tank capacity determines how much water it can hold, the volume of moisture it can send into the air, the room size it can cover, and how often you would have to refill.

Portable devices like ultrasonic humidifiers can range from 250ml to 6-liter tank size, while central humidifiers can hold up to 23 liters. If you don’t have time for frequent refills, a considerably large tank will be your best bet. However, make sure the tank capacity is not too big for your room size as this may cause condensation on windows and walls which can invite mold growth.


The run-time of an air humidifier depends on its tank capacity. The bigger the tank capacity, the longer its run-time. You can get between 24-50 hours of run time with a 6-liter tank, while a 2-liter tank can get you up to 24 hours of run-time.

Another contributing factor is the mist setting. A low mist setting will typically last longer than a high mist setting. A product’s run time is usually stated in its description, so you can easily check that.

Cold mist vs. warm mist

Cold mist humidifiers are more commonly used than their warm mist counterparts. The former is used to humidify the air and has better efficiency than the latter. However, the decision is based entirely on your needs. If you want to heat your room during cold weather, you can opt for warm mist units. Some products also offer both options, so if you want both, these types of products are your best bet.

Adjustable mist level

The device you’re looking at should offer adjustable mist levels, so you have options. This is particularly important because air dryness changes depending on the weather or season, so you should be able to adjust the mist level to balance the room humidity. This factor is also important because a high mist level may not be suitable for a small room and vice versa. Being able to adjust the mist levels keeps you in control of your room’s humidity.

Manual vs. smart control

A manual control air humidifier typically uses knobs or buttons to turn the device on/off or adjust the mist settings from low to high. A smart control, however, allows you to do these via an app or voice control. That way, you can be several feet away from your device and still be able to control it.

Quiet operation

You should ensure the product works quietly or near-quiet, especially if you’re getting it for your bedroom or baby’s nursery. Most ultrasonic humidifiers work silently, so be on the lookout for that when shopping.


The device should be constructed with safe, non-toxic materials. If it is made from plastic, check to ensure it is BPA-free and FDA-approved. Likewise, the device should have an auto shut-off feature that cuts off operation at low water levels to prevent accidents or damage to the device.

How to clean and maintain a humidifier

Following these steps, you can regularly clean your portable air humidifier to prevent mold growth or bacteria:

  • Unplug the device
  • Empty the tank and use the cleaning brush (most units come with one) and hydrogen peroxide solution or vinegar to scrub it clean. Rinse thoroughly and leave to dry.
  • Wipe the body clean with a towel soaked in vinegar and again with a wet towel. Finally, wipe with a dry towel.

To maintain your device, make sure to

  • Always use distilled water
  • Avoid extremely high humidity levels to prevent mold growth
  • Place in a dry area
  • If it uses a filter, replace it regularly.
