6 Best Small Room Humidifier Reviews

1. Miroco Ultrasonic Cool Mist Humidifier (TOP PICK COOL MIST)

VIEW PRICE

Main Features:

  • 360 degree rotatable mist nozzle
  • 6L tank
  • 20-60 hours continuous use
  • 26db ultra quiet
  • Adjustable mist levels with maximum output of 300 ml/h (0.08 gal/h)
  • Filter-free

For adding moisture to air that is warm but dry, this sleek and powerful design is top pick among our cool mist humidifiers. The Miroco is packed with user friendly features. It’s very easy to carry, refill and clean; has adjustable mist levels to suit personal preferences; has a rotating nozzle so you can direct the cool mist wherever you want; and shuts off automatically when water runs out to prevent overheating.

The other feature that makes the Miroco our top small humidifier pick is the quiet operation. The large capacity tank and long running time combined with whisper quiet operation makes this one of the best humidifiers for nighttime. Light sleepers, babies and pets can rest easy undisturbed by loud humming or the sounds of water drops, and the night light helps them see the home gadget and other surroundings at night.

This humidifier is great for everyone but is an especially ideal humidifier for families with young children and babies. Just set your new humidifier on the floor, table or shelf then sit back and enjoy more humidity in the air and relief from dry skin and nasal congestion, as well as a better sleep.

The Miroco ultrasonic cool mist humidifier is available at a mid-range price that offers great value for top features and since it is a filterless humidifier, you will not have the ongoing cost of replacement filters.

Main Features:

  • 360 degree rotatable mist nozzle
  • 6L tank
  • 20-60 hours continuous use
  • 26db ultra quiet
  • Adjustable mist levels with maximum output of 300 ml/h (0.08 gal/h)

If you live in a part of the country that experiences winter weather, you’ve likely experienced the chapped lips, itchy skin, stuffiness and static electricity that seem to persist when the temperature is cold and the air is dry. A warm and cool mist humidifier is a great solution for these winter months and cool conditions. Increasing the temperature of the air and keeping the relative humidity above 43% can help you fight colds and stay healthy throughout winter.

This small room humidifier from TaoTronics delivers both warm and cool mist with quiet operation, three mist levels to choose from and top features including sleep mode and automatic shut-off for safety.

The large capacity water tank and long run time allows you to go days without refilling the tank, and when you do, it’s easy to lift the detachable tank using the handle, and to refill from the top without messy spills. That same large opening makes this humidifier easy to clean using the cleaning brush and mineral absorption pad included.

This is one of the more expensive humidifiers that we reviewed, but it’s well worth the price for a humidifier that delivers cool mist and vaporizer warm mist with so many features. This is a humidifier you’ll use and love for small rooms and offices all year long.

Cons/Cautions: Keep in mind that for safety reasons, the warm mist does not work in sleep mode. Only the cool mist works in sleep mode. And because the mist near the nozzle can get very hot, this humidifier is not ideal if young children are around. Also, essential oils should  not be added to the water tank.

Buying Guide: Humidifier FAQs

picture of person sleeping beside everlasting comfort ultrasonic cool mist humidifier

Is a cool mist or warm mist humidifier better?

You may have seen reviews of cool mist and warm mist humidifiers and are wondering which humidifier is better. Whether a cool mist or warm mist humidifier is better depends on the climate you live in and the seasons you experience. A cool mist humidifier adds moisture to dry air but does not increase the temperature. A cool mist humidifier is useful if the air is warm and dry. It’s a great choice for places with a warm or moderate climate year round. A warm mist humidifier adds moisture and heat to cold dry air. A humidifier with warm mist is useful during the winter months. A humidifier that produces both cool and warm mist is a great choice if you live in a city where you experience all seasons of cold, moderate and warm weather.

Is a filter or filterless humidifier better?

Our reviews of the best small room humidifiers includes mainly filterless humidifiers. The ultrasonic humidifiers work by creating a mist using vibration instead of by cooling or boiling the air. Filter-free humidifiers are an economical and sustainable choice in the long run, but aren’t the best humidifier for people with asthma as germs and bacteria are not filtered from the air. A humidifier with filter will trap dust, germs and bacteria but will also be louder and require more cleaning than an ultrasonic humidifier..

What causes fine dust from humidifiers and how can you avoid it?

Using hard water in your humidifier can cause fine dust left on your furniture. To avoid fine dust from humidifiers, used distilled or demineralized water instead of hard tap water, or choose a humidifier with filter.

What’s the difference between a humidifier and vaporizer?

You may have seen both terms and are wondering what is the difference between a humidifier and a vaporizer. It is essentially the difference between a cool mist and warm mist humidifier. A vaporizer is a type of humidifier that uses boiling water or steam to warm the air. Since a vaporizer or warm mist humidifier boils water, it has less chance of carrying germs and bacteria than a humidifier that emits cool mist only, and would be preferred by allergy and asthmas sufferers. [1]

How do you clean a humidifier?

It is always best to follow the cleaning instructions provided with your appliance. Our humidifier reviews include mainly filter-free humidifiers that are easy to clean with the tools supplied. You can also use a simple household cleanser of vinegar which effectively dissolves calcium.It’s important to clean the humidifier regularly to avoid the buildup of mineral deposits that result from the use of hard tap water. [2]

Is a humidifier with aromatherapy good?

Aromatherapy has many benefits. A humidifier that has the dual function of diffusing essential oils is a great way to get the health benefits of aromatherapy with one handy home gadget. Fragrancing your home or office with different essential oils can help you relax, focus, energize and even produce positive memories. [3]
