Electric desktop no leaf air cooling bladeless fan humidifier diffuser.
This is an electric fan (110 or 220Volts), without blades that, due to the fact of having a water reservoir, generates (through piezoelectric effect) wind with vaporized water. It really helps on decreasing the temperature something around between 3-4 Celsius degrees. Water tank amount is enough to assure the working around 6 hours. I like it, so much.
