There are four primary types of Holmes® humidifiers – Cool Mist, Warm Mist, Ultrasonic, and Vaporizers.
Cool Mist (Evaporative Wick) humidifiers gently disperse cool, invisible mist into the air. Dry air is pulled into the system, passing through a saturated wick filter. Moisture is fan-evaporated into the air while sediment, minerals, and other impurities are trapped in the filter. The result is clean, pure, refreshing mist. These safe and effective humidifiers work well in larger rooms, and the cool, refreshing mist is comforting in arid climates.
Warm Mist models produce warm, soothing visible mist for added comfort during cold winter months. A gentle boiling process traps impurities, releasing clean warm vapor into the air. Many models offer humidistat technology and medicine cups to disperse inhalants for added relief.
Ultrasonic humidifiers produce fine, lighter mist that quickly disperses humidity into the room. In these models, a transducer vibrates water at ultrasonic speed to break it down, producing pure, refreshing visible cool mist. Ultrasonic models are quiet, refreshing, and low-maintenance.
Vaporizers produce warm, soothing vapor through a boiling process that removes impurities from the water before releasing clean, fresh moisture into the air. Vaporizers are compact and cost-effective, and do not include a removable tank.
