Warm Mist Humidifiers


Years ago, warm mist humidifiers were named vaporizers according to the process in which they generate humidity. Those humidifiers used an internal boiler plate to boil water into a warm steam output. Unfortunately, these humidifiers proved to be very unreliable due to varying water conditions. The slightest amount of hardness in your water would result in minerals scaling onto the boiler plate, resulting in an irreparable appliance that must be thrown out and replaced. Despite a history of a short lifespan, warm mist humidifiers remain extremely popular as these are what you likely grew up using when you had a cold or the flu. Today’s warm mist humidifiers have been designed to cope with our varying water quality issues and are now very reliable and effectively humidify larger areas than ever before. Warm mist is widely considered healthier since the boiling of water destroys waterborne microorganisms and bacteria. Ultimately, warm mist humidifiers are your best choice when you need relief from asthma symptoms, a cold, the flu or a respiratory infection.

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.
