Pure Warm Mist: Boils water to release steam; up to 212°F high-temperature steam; produces cleaner warm mist with lower water quality requirements; reduces dust common in ultrasonic humidifiers; ideal for families with children, elderly, or pets sensitive to air dryness
Rapid Humidification: Begins mist production in 30-40 minutes of operation; delivers a maximum 500 mLl/h output with a 4-liter capacity; covers up to 500 square feet; offers standard, fast, and sleep modes; timer settings from 1 to 12 hours
Safety Protection: Features a child lock and a special design above the mist outlet to prevent accidental contact; auto shuts off if the unit is tilted beyond 45 degrees, if the water tank is empty (with a red indicator lights up), or if the top cover is opened
Easy Maintenance: filter-free design requires no replacement parts; dishwasher safe components include a removable top cover and a 304 stainless steel tank
Usage Tips: Filtered tap water recommended; clean the water tank and removable cover plate regularly, at least once a week; use citric acid or vinegar for descaling (better with auto clean mode); avoid using highly concentrated acidic cleaning solutions
