Working through Ultrasonic waves, USB-TOY52 Humidifier is presented as a counter-measure against the dry-eye problem of people who have to work long hours before the computer screen. It is a compact device (W80×D60×H160mm), weighs 450 gr.and costs 5,229 yen.

Actually, compared with the USB Humidifier by Greenhouse we introduced 2 days ago New humidifiers from Green House, Humidify your air with SuperSonic WaVeS, it is even heavier and more expensive.

Anyways, choice is up to you..
