What is a Steam Humidifier?
A steam (warm mist) humidifier works by boiling water up to 212°F (100°C) and releasing it as a gentle warm mist. This high-temperature process naturally sterilizes the water, producing cleaner, healthier mist that’s safer for sensitive respiratory systems.
By contrast, an ultrasonic humidifier uses vibration to turn water into cool mist, but it can also release minerals, dust, and bacteria into the air. This often leaves behind white residue and can irritate those with allergies or breathing issues.

Hygienic Steam
Unlike filters or plastic tanks, this humidifier uses a 304 stainless steel tank that boils water at 212°F, releasing 99.9% germ-free steam for cleaner, healthier air.

Easy to Clean
No filters, no hassle. The removable stainless steel tank and cover are dishwasher safe, and the built-in auto-clean mode helps remove any mineral buildup.
Rapid Humidification
Tired of waiting for dry air to improve? With a powerful 500 mL/h mist output, this steam humidifier increases humidity levels nearly 2.5× faster than ultrasonic units (200 mL/h). Enjoy comfortable humidity in just 30–40 minutes.
Wider Coverage
Ultrasonic humidifiers keep mist in a small zone (about 250 sq. ft.). Steam spreads naturally, reaching up to 500 sq. ft., making them ideal for bedrooms, living rooms, or nurseries.
Filter-free design means no replacement parts and no extra expense.
Protective outlet prevents accidental steam contact.
Soft night light adds comfort and relaxation.
Auto shut-off activates with low water levels or if the humidifier is tilted beyond 45°.
