In natural surroundings, air is filled with thousands of negatively charged ions that attach themselves with positively charged dust particles and create a type of natural ionic air purifier. When this technique is used in homes, ionic air purifiers emit innumerable number of negatively charged ions that stick to dust particles and form a heavy mass. This becomes too heavy to float in air and settles down on ground. In this way, it wards away dust particles from reaching your respiratory tract.

It all started with one woman’s frustration with losing weight. She was an ordinary housewife who had tried every fad diet known to mankind. In desperation she turned to a free diet clinic in New York City. She stuck with diet and lost 20 lbs but soon lost her motivation.

It was also about changing one’s habits and getting support from people who cared.

The company rapidly began to expand as their former members branched out and formed franchises around United States and abroad.
