1 . Portable and Small volume
2. build-in colorful light
3. generate cascade negative ions
4,wash air
5,diffuse fragrance

Theory  :
1 .Water –washes function .Air is purified with air as filter ,Fan motor is rolling in a high speed to creat a wind current inside the machine ,The rurrounding air is to be sucked into water tank ,and washed by water ,as a result fresh air will release out of the outlet
2 . the water will dash on the inside piahbin by wind rotor through the high-speed rolling motor , it will make man-made waterfall , and thereby   generate natural negative ions ,
