It can be quite difficult to find an adequate humidifier for a large bedroom, living room, or space. We have therefore decided to compile a review of some of the best humidifiers for larger rooms. Each of the humidifiers reviewed below has a large water capacity of over 1 gallon for continuous mist production. They also have the necessary design and features to properly humidify larger rooms.

Moreover, these humidifiers also help in the prevention of the potentially adverse effects poorly humidified air has on your health. Lack of properly humidified air may lead to dry skin/scalp, sinus problems, dry throat, chapped lips, and more. Therefore, it is important to have a good humidifier for the large rooms within your home.

There are three general types of humidifiers available on the market. Each one has its strong and weak points. So, the choice rests with the users based on compatibility between their needs and the features of each humidifier type.

Three general types of humidifiers

Ultrasonic cool/warm mist humidifiers:

Ultrasonic cool/warm mist humidifiers use high-frequency mechanical oscillation that transforms water into the form of mist which is then released into the atmosphere.

  • Requires little to no maintenance
  • Do not produce noise and are generally the quietest because the vibration frequency is higher than we can hear
  • Are more effective in larger areas
Evaporative cool mist humidifiers

Evaporative cool mist humidifiers use internal fans to blow air at a moistened wick causing the evaporation of the moisture within that wick which releases into the atmosphere as cool mist.

  • Requires some maintenance and filter replacement every few months
  • Are generally the loudest but the noise sounds more like white noise and fades into the background
  • Are more effective in larger areas
Steam vaporizer warm mist humidifiers

Steam vaporizer warm mist humidifiers boil water using a heating element that produces a warm soothing mist that disperses into the atmosphere. They are also known as vaporizers and steam humidifiers. These units are very hygienic as the process of boiling water into warm mist kills bacteria and other impurities.

  • Require frequent cleaning and are generally more difficult to clean
  • Produces cleaner mist than most cool mist humidifiers
  • Great for treating colds and the flu
  • Produces very little to no noise
  • Not very practical for large rooms
