In terms of humidifying, there are little differences between cool mist and warm mist models. Both types of humidifiers will add moisture to the air through various technologies. With optimum humidity level, it will relieve cold and allergy symptoms caused by dry air exposure. However, cool mist will consume less electricity than a warm mist humidifier as there are no heating elements. Cool mist humidifiers also offer slightly better coverage and lower pricing even though the differences are insignificant. You will have better peace of mind with a cool mist as there is no burn risk towards children from the steam. Warm mist humidifiers are perfect for winter use as it creates warmness on its surrounding air. It is suitable for bedroom use with the silent operation that does not involve a fan.

Why Cool Mist Humidifier

Cool mist humidifiers disperse room-temperature mist that is safe and effective. It will rehydrate dry skin, chapped lips, col allergies, flu, and asthma symptoms. Evaporative or ultrasonic are the two different types with unique technologies to humidify the air. Evaporative AKA wick humidifiers use a fan to pull air into the water-saturated wick filter from the reservoir. The air will then absorb the moisture from the filter and emit moist air out. Ultrasonic humidifier, on the other hand, uses a small metal plate that vibrates at an ultrasonic frequency. The strong vibration will break down water particles inside the tank and convert them into water vapor before releasing it. Ultrasonic is much quieter and effective but will draw more white dust in it.

Cool Mist Pros and Cons

  • Cover more space yet use much less electricity than warm mist humidifier.
  • Slightly cheaper in price compared with the warm mist counterpart.
  • Suitable for baby, children as there is less hazard risk from water spilling.
  • More mineral build-up thus higher chance of mold and mildew growth in the bucket.
  • Models like evaporative humidifiers come with a fan and filter that needs replacing.
  • Higher maintenance requires cleaning every 3-7 days depending on the usage frequency.

Why Warm Mist Humidifier

Warm mist humidifiers generate heat through its internal system and emit warm, visible steam into the air. Great in reducing airway inflammation, congestion, nosebleeds, sinuses, and sore throat. By heating the liquid in the tank to a boiling point, the water will vaporize and moisturize the air evenly. No fan is needed during the whole process as the pressure generated from the steam is enough to force the air out. Great for winter use as the heat will warm up the room slightly without affecting the dampness level.

Warm Mist Pros and Cons

  • Most warm mist humidifiers are quieter than cool mist due to the lack of an internal fan. Best for bedroom use.
  • Generates a little bit of heat that can be useful in the winter season.
  • Less cleaning required as there is little mineral build up with heat killing most of the microorganisms.
  • Use more electricity due to the nature of heating elements.
  • Dangerous when placed next to children. The dispersed mist can reach a high temperature that would incur a burn when touched.

Cool Mist VS Warm Mist Humidifier for Babies

Cool mist humidifier is best for babies at home. Hands down. This is because the mist released from a warm mist can reach close to a boiling temperature. It may cause a burn if children get too close to the steam or the humidifier is accidentally knocked over and spill all over the hot water. Very dangerous as baby or children tends to fiddle around with all the stuff at home.

Of course, a cool-mist humidifier will provide swift and dependable humidification. Baby has a narrow nasal passage and developing lungs that are very sensitive to poor air quality. With a cool mist humidifier, it will soften mucus, alleviate nasal congestion and prevents germs from sticking around. Without any breathing difficulty, the baby can sleep comfortably throughout the night. Parents will also not have to deal with a cranky baby that can be energy-draining to say the least.

Which is Better Cool Mist or Warm Mist Humidifier?

In short, a cool-mist humidifier would be the better choice as it is slightly cheaper yet has better humidification coverage. It is also much safer to be used around the house if you have children at home. The ultrasonic series will also generate minimal noise similar to a warm-mist humidifier. Then again, getting a warm mist humidifier would also have its own advantages mainly mold resistance. At the end of it all, both models will humidify the air and you can’t go wrong picking on either one.
