Ultrasonic Humidifiers. Warm and Cool Mist Humidifiers


The best way to combat dry air and reduce your susceptibility to an infection is to invest in a humidifier. Ultrasonic humidifiers use high-frequency vibrations to generate a micro-fine mist which is output into your room for increased humidity. Cool-mist humidifiers are best used to combat allergies while warm-mist humidifiers offer relief for those with asthma, a cold, the flu or a respiratory infection. Households with excessively hard water often use a water softener to counteract the high mineral content. Unfortunately, a water softening system uses calcium, magnesium and sodium ions, and those high sodium levels will create white dust when used in an ultrasonic humidifier. Ultrasonic humidifiers are our top choice for your bedroom as they offer virtually silent operation.

For the best soothing, warm steam humidifier, you might consider our Air-O-Swiss S450 Steam Humidifier.
For a quiet bedroom, we recommend our PowerPure and our Air-O-Swiss Humidifiers.
For a large open area, we recommend our evaporative, fan-based AIRCARE Humidifiers and our new Brune Professional Humidifier.

More about Ultrasonic Technology:


Ultrasonic Warm/Cool and Cool Mist Humidifier Pluses

  • Ultrasonic humidifiers are quieter than evaporative cool mist units
  • When using the warm mist option, the mist will evaporate faster into the air so you will be able to increase the humidity very fast. If using the humidifier in a bedroom you will not need to have it going all day.
  • Warm mist humidifiers feel the most comfortable especially in Northern winters
  • Ultrasonic humidifiers require less cleaning
  • There is no limit to how much humidity you can add to the air since the water mist droplets will not decrease regardless of the room humidity. Ultrasonic humidifiers are particularly beneficial if one wants to raise the humidity over 45% or higher such as preserving certain materials or products for example cigars, musical instruments, etc.


Ultrasonic Warm/Cool and Cool Mist Humidifier Minuses

  • They cover a smaller area than the evaporative cool mist humidifiers, often no more than one decent sized bedroom.
  • They require placement at least 2 feet from the floor to prevent the moisture from hitting the floor before it has a chance to evaporate. Note that as the humidity increases in the room, the mist being emitted will take longer to evaporate into the air. Therefore, you may find it necessary to raise the humidifier positioning higher from the floor and/or use the warm mist option if available.
