What is warm mist humidifier?
Warm mist humidifiers heat water to boiling point to disperse warmer air. However, this type comes with a heating element that does the boiling process. After heating the water, the hot water is further sent to a cooling chamber inside the unit to cool it to a certain degree acceptable to the human skin.

From research studies and consumers’ reports, humidifiers that release warm mist air are generally recommended for cold wintertime because of their capacity to deliver warmer air that eliminates colder air. They are also the best kinds of humidifiers for sinusitis, allergies, and asthma patients as the warm mist produce help relieve sinus congestion. It also prevents symptoms of allergies and further reduces the rate of asthmatic episode occurrence.

Besides, you will get safe steam air to breathe because, during the boiling stage, bacteria and molds are 100% destroyed. However, warm mist humidifiers provide the best steam ever without micro-organisms. More so, warm mist humidifiers are of two types, such as the steam unit and the vaporizer. From the sampled opinion, vaporizer seems to be the best of the two because they produce steam with lesser mineral deposits compare to the steam models.

Warm Mist Humidifier Benefits
  • Have the capacity to collect left over mineral deposits on the water heated.
  • Provides healthier air devoid of germs or micro-organism
  • Have the ability to warm up cold room with warmer mist to fight colder air.
  • More quiet compare to cool mist unit because they have no fans that do generates noise.
  • They are available in small sizes and designs that enhanced mobility.
Drawback of warm mist humidifiers
  • They consumer more electricity (energy) bills unless you’ve an energy rated unit.
  • Not suitable for homes with children because they may sometimes release hotter mist that can be hazard to young ones.
  • Require regular clean to clear out accumulated particles gathered from water in the course of heating.
  • They are more expensive compare to cool mist humidifier due to heater in them.
