Ions Can Be Bound Molecules Or Atoms That Contain An Electric Charge And Exist in Nature in Various Sizes. Small Ions Last Only 30 to 300 Seconds Before Losing Their Charge, But Are Extremely Active. In Nature, Negative Ions Are Generated By Processes Such As Sunlight, Lightening, Waves From The Ocean, And From Waterfalls. “Concrete Jungles” Minimize The Natural Production Of Negative Ions By Disrupting The Delicate Electrical Balance Between The Atmosphere And The Earth. Crystal Clean Air Purifiers Recreate Them With Electrode Pins (“Needlepoints”) To Electrically Produce Negative Ions. This Method Produces A Density That Is Many Times Higher Than The Negative Ion Level Found At Niagara Falls, The Highest Natural Producer Of Negative Ions And One Of The Healthiest Environments In The World.”
