Explanation

Ultrasonic humidifiers use a metal diaphragm vibrating at ultrasonic frequencies (beyond human hearing) to break water into an extremely fine cool mist, which is then dispersed into the air - making rapid vibration the defining mechanism. An infrared humidifier does not exist as a standard humidification category; infrared refers to heat radiation, not mist production. An electromagnetic humidifier is not a real product category and appears as a plausible-sounding distractor. A steam canister humidifier works by heating water until it boils and releasing steam, which involves heat rather than vibration.

Memory tip: Think "ultra-sonic = ultra-vibration." The prefix "sonic" relates to sound waves, and ultrasonic devices vibrate at sound frequencies too high to hear - that rapid vibration is exactly how they turn water into mist.
