The air freshener wearing on the neck -- Electronic mask

The world's smallest air freshener -- "i-Fresh" anion generator uses the latest scientific and technological achievements in the world. It generates uses high pressure with the thinnest, smallest of the piezoelectric ceramic voltage transformer and other components, ionize air in the macjine and generates about 5 million per protect the human, especially the elderly, children, women, sick, disabled from cover the human's mouth and mose tightly, make people feel uncomfortable. Apart from it's small and light, there is no noise, no electromagnetic radiation, and does not suffer from electromagnetic raditation to prevent other radiation.
