Quiet Ultrasonic Humidifier

The Lasko UH300 uses ultrasonic technology to deliver both warm and cool mist for year-round comfort. It suits anyone looking to maintain indoor humidity within the 30% to 50% range recommended by the Mayo Clinic. The unit runs quietly and comes fully assembled with no filters to replace.

Humidistat and Timer Limits

The built-in humidistat lets you set a target humidity level while the 12-hour timer caps continuous operation. On the lowest mist setting the humidifier runs up to 100 hours before the tank empties and the automatic shut-off activates. Three mist flow options provide basic output control without fine-grained adjustment.

Patented Safety Fuse

Patented safety fuse technology cuts power if an electrical fault is detected, a single safeguard that distinguishes this model from basic units. The feature works alongside the empty-tank shut-off to prevent dry-run damage. Buyers who need app connectivity or voice control will not find those functions here.
