Capacity and intended use

The Optimus U32030 is a 3.4-gallon warm mist humidifier designed for rooms up to 700 sq ft. It suits households that want consistent humidity without daily tank refills. The medicine cup allows optional inhalant use when needed. Its variable humidistat lets you set a target level and leave the unit to maintain it.

Sustained operation

On the high setting the unit runs for 24 hours before the tank requires refilling. A refill indicator light signals when water is low and automatic shut off activates once the tank is empty. The PTC ceramic heating element with absorption sleeve produces steady warm vapor without the scaling that demands frequent cleaning.

Build and daily handling

The patented Warm Wicking Vapor System means the heating element does not need regular descaling, reducing maintenance time. High, low and medicine cup settings are selected by simple controls on the housing. The 120V 60Hz 520W power draw plugs into a standard household outlet. The tank lifts off for filling and carries enough water for a full day of continuous use.
