FAQ
Q1: Which humidifier technology is better?
A: Neither is universally better — ultrasonic is quieter and more efficient but can emit white dust with hard water; evaporative units are noisier but self-regulate and trap minerals.
Q2: Which should I choose?
A: Choose ultrasonic for quiet bedrooms with soft water; choose evaporative for hard water or hands-off operation.
Q3: Which is safer for babies?
A: Both can be used cool-mist and cleaned properly; ultrasonic’s quiet makes it popular in nurseries.
