Brand new open box Boneco S450 Stem Humidifier with digital control panel. Unit still has protective shipping tapes. Comes with Owners Manual and power cord. The Most Hygienic Way To Humidify This powerful steam humidifier system begins to operate by heating the water to the boiling point. The ensuing vaporized water from the unit then humidifies the room air. The steam humidifier system is the most hygienic way of air humidification, as heating the water to 212°F ensures a bacteria and mineral-free humidification. The S450 is an innovation in application. Steam humidification has been around for a long time and is a very effective way of quickly humidifying living space. We are pleased to offer you the S450 with Clear Mist Technology. The Clear Mist can be seen but more importantly it can be felt. Unlike traditional steam humidifiers, Clear Mist is warm to touch instead of burning hot. Therefore, we can recommend this product for all living areas, even around children. Bacteria and mineral-free humidification Recommended around children Can be operated on the floor Auto Mode & Clear Mist Technology Auto-cleaning mode Ideal for rooms up to 860 sq. ft.
